Texte intégralRésumé :
This dissertation is concerned with the principles of pavement management systems and their applications in western and developing countries. The first part of the dissertation deals with the principles of pavement engineering and the role of the different layers in order to gain the required knowledge in highway pavement components, which will allow a cost-effective repair related to each specific defect. The second part deals with the existing systems for monitoring pavement condition and evaluatest heir benefit in assessingh ighway condition. The study shows the main problems usually militate against using the sophisticated technology in monitoring highway condition and implementing maintenance management systems in some cities in developing countries. In addition to the problems inherent in cities in developing countries, the city of Benghazi in Libya has special factors which have developed as a result of UN sanctions which were imposed in 1992. Therefore, the city of Benghazi has been selected as a case study for this particular research since it is a typical example of most cities in developing countries in terms of size, population and in ten-ns of lack of maintenance resources and skilled labour (Benghazi might have been so well resourcedth at it would no longer fall into the categoryo f developingc ity but for the sanction). The objectives of the study are attained through conclusions which indicate that establishing a pavement maintenance strategy in the city of Benghazi based on any or some of the sophisticated technology in road condition monitoring is not appropriate. This conclusion is tested by manufacturing a unique prototype measuring machine and using it in pilot monitoring exercises in the cities of Newcastle and Sunderland. The results of these pilot exercises are analysed to evaluate the benefit which such appropriate technology equipment can bring to the issue of monitoring of pavement condition in cities in developing countries having problems similar to those that prevail in Benghazi. The prototype equipment developed in this study is unique in that it is purely mechanical and uses no electronics in monitoring road condition. Moreover, all parts of the machine are fabricated from materials available in most cities in developing countries and therefore such machines could be easily maintained locally. The prototype described in this study is not only relevant to road monitoring but points the way towards the development of similar equipment in many engineering situations in developing countries. This research study points engineers in similar conditions in the direction that the Author thinks they should follow in applying their engineering abilities in developing countries.

Texte intégralRésumé :
This thesis describes the development of a new Road Traffic Monitoring (RTM) system designed by a team at the University of Aberdeen, to provide low cost traffic monitoring that maintains the privacy of the driver and provides high quality traffic data for the authorities. The RTM system communicates with vehicles equipped with satellite transceivers attached to Global Positioning System (GPS) units which provide data about position and velocity, enabling a picture to be built up of traffic flow conditions. The author developed an innovative system to maintain the anonymity of the driver in order for the system to be attractive to both authorities and drivers. The thesis focuses on the author's contribution to the project - the design of the major protocols, including polling and 'system wide' strategies, an in-depth study of the statistics of the capacity of the RTM system and the development of a protocol to limit the number of responses from vehicles to a manageable level. The RTM system was implemented as a simulation and all designed protocols and parameters thoroughly tested. It is currently being used by the European Space Agency in a pilot study as the first phase of implementation. The author then envisaged an intelligent control system that would monitor and control the RTM system in real time, optimising parameters dynamically in order for the system to run efficiently and accurately. A hybrid 'Artificial Intelligence' (AI) system composed of a rule based system and a number of Artificial Neural Networks (ANNs) is proposed. A new rule extraction system developed by the author to counter the 'black box' effect of ANNs is then presented, making use of a hierarchical system of Self Organising Maps (SOMs). Following this, an extension to the system is described, using the Quantisation Error (QE) to enable the real time detection of 'unusual' data, or data from outwith the current operating environment, enabling retraining or the return to a previous control situation, to take place. Such a system of ANNs is ideal for use in both monitoring and control of a dynamic real time system such as RTM.

Klingel, Heidi M. « Developing a physical effectiveness monitoring protocol for aquatic organism passage restoration at road-stream crossings ». Thesis, Colorado State University, 2014. http://pqdtopen.proquest.com/#viewpdf?dispub=1558242.
Texte intégralRésumé :
Two US Forest Service draft monitoring protocols are used to assess the effectiveness of design channels at road-stream crossings by comparing their physical channel dimensions to those in the natural channel. Level II physical monitoring is a time intensive, quantitative and statistically based procedure for assessing effectiveness at selected sites. Level I physical monitoring is a less detailed, rapid procedure limited to a few simple measurements and observations for assessing effectiveness at a large number of sites. Study objectives were to: 1) test and refine the field methods for collecting data by the levels I and II physical monitoring protocols; 2) find a meaningful way to combine the data collected by levels I and II into separate effectiveness evaluations by each protocol; and, 3) evaluate whether the level I protocol can be used as a proxy for the level II protocol. Where the two protocols systematically differ, field data help distinguish why.
Study results for all objectives (combined) include: improved field methodologies, recommendations for further development, and separate summary rubrics for the levels I and II monitoring protocols. The recommendations are of three categories; channel metrics/data collection, methods of scoring each metric, and sample sizes. Some of most significant of those recommendations are described within the following paragraphs.
Data collection methods might be improved to save time, increase the accuracy of protocol evaluations, and facilitate agreement between the levels I and II protocol evaluation results. The techniques by which the level I bankfull stage and coarse fraction of the gradation metrics are collected should incorporate level II methods. Instructions for collecting level II coarse fraction of the gradation data should specify measuring all particles within the channel, including particles much larger than the sampling frame. The level I method by which the representative reach is selected should incorporate a basic longitudinal profile survey in which only the most prominent grade controls separating slope segments are captured. Decreasing the allowable gradient difference between the level II design channel and representative reach might also improve accuracy. The method by which the levels I and II protocols compare channel units (or channel unit sequences) between the design and representative reach should be equivalent, as should the rules by which slope segments and channel units are defined. Finally, the channel metrics of low flow width and bed irregularity are inconsistent with the objectives of physical effectiveness monitoring, in that they are aspects of habitat, rather than strong controls on channel form. I suggest they be eliminated from the levels I and II protocols.
The level II summary rubric scores most metrics statistically by a Wilcoxon Rank-Sum test of medians. For most metrics, the Wilcoxon Rank-Sum test appears to be a reasonable way to compare representative reach and design zone data. For the metrics of bed and bank irregularity, however, a test of distributions (e.g., Kolmogorov-Smirnov) is recommended instead. The coarse fraction of the gradation metric would be more fairly assessed if the modes of the particle size (in phi units) were compared instead of the medians. Doing so would allow the design and representative reach gradients to be slightly different (as does the criteria for selecting a representative reach) without penalizing the metric score.
The levels I and II summary rubric tools created were used to evaluate twelve AOP road-stream crossing designs. The performance of the levels I and II summary rubrics were then assessed by the evaluation results at those twelve sites. Levels I and II generally seemed to provide effectiveness evaluations which agreed with site observations, data, and photographs. Further, the summary rubrics facilitated concurrent evaluation of the many channel dimensions which together affect the hydraulic conditions experienced by aquatic organisms. In addition, the simple utility of the levels I and II summary rubric tools should encourage effectiveness monitoring and help restoration practitioners learn from their mistakes, ultimately improving aquatic organism passage design methods and results.

Texte intégralRésumé :
Road network of a region is of a paramount importance in the overall development. Management of road traffic is a key factor for the city authority and reducing the road traffic congestion is a significant challenge in this perspective. In this thesis, a Wireless Sensor Network (WSN) based road-traffic monitoring scheme with dynamic mathematical traffic model is presented that will not necessarily include all adjacent intersections of a block; rather the important major intersections of a city. The objective of this scheme is to reduce the congestion by re-routing the vehicles to better performing road-segments by informing the down-stream drivers through broadcasting the congestion information in a dedicated radio channel. The dynamic model can provide with the instantaneous status of the traffic of the road-network. The scheme is a WSN based multi-hop relay network with hierarchical architecture and composed of ordinary nodes, Cluster-Head nodes, Base Stations, Gateway nodes and Monitoring and Control Centers (MCC) etc. Through collecting the traffic information, MCC will check the congestion status and in defining the congestion, threshold factors have been used in this model. For the congested situation of a road-segment, a cost function has been defined as a performance indicator and estimated using the weight factors (importance) of these selected intersections.
This thesis considered a traffic network with twelve major intersections of a city with four major directions. Traffic arrivals in these intersections are assumed to follow Poisson distribution. Model was simulated in Matlab with traffic generated through Poisson Random Number Generator and cost function was estimated for the congestion status of the road-segments over a simulation period of 1440 minutes starting from midnight.
For optimization purpose we adopted two different approaches; in the first approach,
performance of the scheme was evaluated for all threshold factor values iteratively one at a time, applying a threshold factor value to define threshold capacities of all the road segments; traffic was generated and relative cost has been estimated following the model specifications with the purpose of congestion avoidance. In the second approach, different values of threshold factor have been used for different road segments for determining the optimum set-up, and exhaustive search technique has been applied with a smaller configuration in order to keep computations reachable. Simulation results show the capacity of this scheme to improve the traffic performance by reducing the congestion level with low congestion costs.

Texte intégralRésumé :
Le réseau routier est l'un des atouts majeurs d'un pays. L'évaluation de l’état structurelle des infrastructures de transport routier et de leur évolution dans le temps est essentielle pour l'établissement de plans d'entretien rentables. À cet égard, l'instrumentation des chaussées permet une surveillance continue et à distance sans interruption de la circulation. Cependant, l'instrumentation reste un défi scientifique et technologique majeur en termes de résilience des dispositifs ainsi que de stratégies d'interprétation des données des capteurs. L'objectif global de cette thèse est de prouver la faisabilité du monitoring des routes par technologies de détection embarquées en démontrant l'exploitabilité des données de capteurs pour évaluer le vieillissement de la route et en fournissant une technologie à haute performance et faible intrusion. Nous proposons, via un essai accéléré à l'échelle 1, une validation des jauges de déformation pour la prédiction de l'endommagement par fatigue d'un revêtement routier. Ainsi, nous avons exploré l'utilisation de capteurs embarqués pour le calcul inverse des conditions mécaniques de la chaussée via l'instrumentation d'une route existante avec un réseau de jauges de déformation. La même section d'essai a servi d'environnement pour une première validation d'une nouvelle technologie de détection basée sur l'utilisation de capteurs de déformation flexibles à base de nanocarbone, testés plus tard dans la chaussée dans le cadre d'un essai accéléré. Nous avons ainsi démontré comment la nanotechnologie proposée pouvait répondre aux enjeux de l’instrumentation des chaussées en termes de géométrie, de compatibilité avec l'environnement routier, et de sensibilitéThe road network is one of the major assets in our countries. The assessment of pavement conditions and their evolution with time is essential for the establishment of cost-effective maintenance plans. In this respect, pavement instrumentation allows remote and continuous monitoring with no traffic disruption. However it remains a major scientific and technological challenge in terms of devices resilience to the harsh road environment as well as of strategies for sensor data interpretation. The overall goal of this thesis is to prove the feasibility of embedded pavement monitoring by demonstrating the exploitability of embedded sensor data to assess road ageing, and by providing a high performance, low intrusiveness technology. We propose, via an accelerated pavement test, a validation of asphalt strain gauges as monitoring method for fatigue prediction in a road pavement. Thus, we further explored the use of embedded sensors for inverse calculation of pavement mechanical conditions via the instrumentation of an existing road with a network of asphalt strain gauges. The same trial section was the environment for a first validation of a novel sensing technology based on the use of nanocarbon-based flexible strain sensors, later tested under an accelerated pavement test. Thereby we demonstrated how the proposed nanotechnology can overcome some of the drawbacks of existing sensing devices in terms of geometry, compatibility with the road environment, and sensitivity

Texte intégralRésumé :
A variety of traffic management schemes have been tried in the past to alleviate traffic problems, but with limited success. The European Space Agency proposed a satellite based Road Traffic Monitoring (RTM) system to overcome the limitations in existing schemes. This is studied in Aberdeen in the form of a simulation operating under varying conditions. This simulation has been introduced into the Internet using advanced Web technology to acquaint a wide range of users with the RTM concept. The work that has contributed towards this thesis looks at different approaches used for incorporating pre-processing and post-processing modules to strengthen the RTM simulation on the Web. A Database Management System was integrated into the system to improve data storage and manipulation tasks. This acts as the central coordinator to several sub-applications within the RTM system. A Graphical User Interface has been added to the front end of the simulator to provide easy access into the simulation through a sophisticated visual display. The post-processing needs are being handled by a spreadsheet suite. Techniques that were followed to integrate these modules with each other or with the core simulator have been considered in detail. The spreadsheet facilities have provided analytical ways and means of interpreting RTM system characteristics and performance criteria satisfactorily. As the thesis proceeds from the beginning to the end, it reflects how the original RTM simulator has evolved into a powerful simulation tool for analysing the effects and underling protocols of the RTM system comprehensively.

Texte intégralRésumé :
Traffic collisions cost Uganda millions of dollars each year. The purpose of this descriptive case study was to describe the strategies and processes needed to implement a road management system. Such a system would significantly reduce the fatalities and accidents in Uganda, improve the transportation within Kampala's business district, and increase business profitability. Three conceptual theories framed the research study: management theory, strategic management theory, and criminology theory. Using a snowball sampling strategy, data were collected from open-ended interviews, questionnaires, observations, and archived documents from 20 administrative participants in the government and organizational leaders involved in the transport operations and transport services in the Kampala business district in Uganda. Data were analyzed using 3 phases: (a) interpretational analysis, coding, and grouping segments; (b) structural analysis, consistency, and quality; and (c) reflective analysis, consequences, what, when, where, and how. Five themes or action requirements emerged from the data analysis: to improve transport operations and transport services profitability, reduce traffic jams and fatalities, provide sufficient driving training, maintain road infrastructure, and maintain traffic law enforcement. The findings and recommendations from this study may improve the profitability of businesses, reduce the traffic jams and fatalities, and improve the gross domestic product of Uganda, thereby contributing to positive social change.

Texte intégralRésumé :
Road collisions negatively affect the lives of hundreds of Canadians per year.
Unfortunately, safety has been typically neglected from management systems. It is
common to find that a great deal of effort has been devoted to develop and implement
systems capable of achieving and sustaining good levels of condition. It is relatively
recent that road safety has become an important objective. Managing a network of roads
is not an easy task; it requires long, medium and short term plans to maintain, rehabilitate
and upgrade aging assets, reduce and mitigate accident exposure, likelihood and severity.
This thesis presents a basis for incorporating road safety into road management systems;
two case studies were developed; one limited by available data and another from
sufficient information. A long term analysis was used to allocate improvements for
condition and safety of roads and bridges, at the network level. It was confirmed that a
safety index could be used to obtain a first cut model; meanwhile potential for
improvement which is a difference between observed and predicted number of accidents
was capable of capturing the degree of safety of individual segments. It was found that
the completeness of the system resulted in savings because of the economies obtained
from trade-off optimization. It was observed that safety improvements were allocated at
the beginning of the analysis in order to reduce the extent of issues, which translated into
a systematic reduction of potential for improvement up to a point of near constant levels,
which were hypothesized to relate to those unavoidable collisions from human error or
vehicle failure.

Texte intégralRésumé :
In the late 1980s and early 1990s few transportation agencies around the world considered performance-based specifications as an alternative to improve the efficiency of the services provided to the public. These initiatives are better known as Performance-Based Road Maintenance (PBRM). PBRM calls for performance-based work, in which a desired outcome is specified rather than a material or method. This type of specification promises to be an excellent tool to improve government efficiency in maintaining transportation networks; however, without proper monitoring, it could likely yield adverse outcomes. Since PBRM is relatively new, the availability of reliable and comprehensive sets of guidelines to evaluate the effectiveness and efficiency of this type of specifications in the roadway maintenance arena is limited. Transportation agencies currently rely on criteria and procedures they have had developed from their traditional methods used to evaluate performance. Unfortunately, some of these procedures cannot appropriately assess the benefits, if any, accrued by the government as a result of implementing performance-based specifications for the maintenance of the roadway system. This research presents the development of a framework for monitoring PBRM more comprehensively and accurately. The framework considers the assessment of five main areas -- Level of Service Effectiveness, Cost-Efficiency, Timeliness of Response, Safety Procedures, and Quality of Services -- in order to guarantee the comprehensiveness and reliability of the evaluation process. The major contribution of this framework is to provide transportation agencies with guidelines for evaluating the effectiveness and efficiency of PBRM as an alternative delivery method to maintain and preserve the roadway system.Ph.

Vick, Steven. « Automated spatial progress monitoring for asphalt road construction projects ». Thesis, University of Cambridge, 2018. https://www.repository.cam.ac.uk/handle/1810/278795.
Texte intégralRésumé :
Construction progress monitoring allows schedule and/or cost deviations to be identified early enough to effectively implement corrective actions. At least 77% of transportation projects experience cost overruns, and as much as 75% of these overruns have been attributed to “real” construction management factors like progress monitoring. Progress is measured on road construction sites in terms of completion percentages at various activity and work package levels. This percentage is then used to identify schedule deviations and support the earned value analysis often used as the baseline for contractor progress payments. Unfortunately, the current methods for producing these completion percentages are not as correct or time efficient as they should be to enable effective project control. The objective of this research is to develop, test, and validate a novel solution for automatically producing completion percentages and progress status determinations that are more correct and time efficient than those generated in current practice. The proposed solution seeks to automatically detect incremental progress on road design layers in 3D as-built point cloud data generated using unmanned aerial photogrammetry and a novel data simulation approach. A parallel as-planned progress estimate is also automatically prepared using 4D information, and the progress status determinations are made by comparing the two results. This solution was tested on 15 datasets (13 simulated and 2 real-world) representing a variety of road designs and progress conditions. The method achieved an average 95% F1 score in layer detection on the real-world data, and mostly outperformed current practice in correctness. The automated processing of as-built and as-planned data to produce the progress estimate took 12 seconds for the real world data, which was indeed faster than the current practice equivalent. Although the research objectives were met, there remains room for further improvement, particularly in regards to the solution’s robustness to occlusions on the monitored surfaces.

Texte intégralRésumé :
The road network is extremely valuable. Road Administrationsare expected to invest maintenance funding in a way thatreturns maximum benefit to road users. Cost-benefit analysis isone method to ensure that an adequate return in terms ofbenefits results from committing expenditure. Today,cost-benefit calculations are frequently used as a base fordecision making of investments. The surges for such methods inthe maintenance management sector are increasing.
Up to the present, one reason for not analysing costs andbenefits for various maintenance management measures has beenthe lack of knowledge about comfort benefits for road users inquantitative monetary terms. The aim with this thesis is toinvestigate motoristsapprehension of pavementmaintenance management and winter maintenance operations. Thefinal goal is to find out their willingness to pay fordifferent levels of road maintenance management. Those valuescan later be used in cost-benefit calculations and also ineffect models of road maintenance management.
Due to the pioneer status of this study, focus groups andin-depth interviews as well as a number of pilot studies havebeen carried out before a main survey with stated choiceexperiments could be designed. These exploratory studies showedthat the interviewees were familiar with the types of roadsurface damage that exist and in many cases mastered the sameterminology as the Road Administration and others. Showingpictures of well-known types of road damage lead to highermonetary valuations of getting better road standard incomparison with just text descriptions. One reason for thatcould be the requisite severness of the damage in order toillustrate a certain road maintenance shortage. The respondentswith the text descriptions could have stated their preferencesfor an, in their own minds, average shortcoming while the groupwith access to photograph of road damage all saw the samesevere damage. Illustrations of different road maintenancestandards make it possible to control the respondentsinterpretation of the maintenance management standard valuatedbut could lead to high monetary estimations.
Driving comfort was very important to the interviewees inthe exploratory studies. That was manifested in the pilotstated choice surveys, which resulted in high willingness topay for better pavement management.
The main study consisted of two surveys; the first one wasabout pavement maintenance management and was carried out inOctober to November 2000 and the second one took place inFebruary to March 2001 and was about winter maintenanceoperations. Both the pavement and the winter survey includedattitude questions and two stated choice experiments. Theresult showed that the maintenance management status of theroad network was important to car users. For example, the worstpavement damage was roughness; the motorists were willing topay 1.7 SEK (Swedish Crowns) per kilometre to avoid roadsdamaged in their full length. The least harmful damage of thosestudied was cracks; the willingness to pay to avoid that was0.5 SEK per kilometre. For more rapid snow clearance, the carusers were willing to pay 60 to 80 SEK per year for getting theroads cleared from snow one hour earlier than the currentstandard implies. The willingness to pay for driving on bareroads in comparison with snow roads was 0.4 SEK per kilometre.Statistical tests on the models showed that the parametervalueswere well estimated.
In the pavement as well as in the winter survey, a clustergroup analysis was performed in order to test the heterogeneityof attitudes and behaviour to road maintenance management. Theanalysis resulted in two separate groups in each survey. Onegroup consisted of drivers who reported to be very influencedby the level of maintenance management regarding chosen speed,joy of driving and so on. The other group reported to be lessinfluenced and had lower acceptance of higher road tax for thepurpose to increase the maintenance management standard.Separate stated choice models revealed that the differences inattitudes could also reflect the respondentswillingnessto pay for higher road maintenance standard. However, thedifferences were only small and the different groupsmonetary valuations were not found to be significantlydifferent from each other.
The result of this study, better knowledge aboutmotoristsapprehension of maintenance management, theirattitudes to driving comfort and road standard and theirmonetary valuations of different levels of pavement maintenanceand winter maintenance operations, opens up the possibility tomake cost-benefit analysis of various maintenance managementprojects. The impact of the monetary values found in this studyhas been studied in a limited cost-benefit analysis.

With a degrading road infrastructure and dwindling public funds, governments are turning towards the private sector to develop roads and finance them though toll revenues. However, these high stakes endeavors were not always successful; in other words, they were not able to provide a fair return to the sponsors and investors while guaranteeing the public welfare and satisfying the government interests. A review of the international experience of toll roads, with a focus on developing countries, suggests that if a thorough and pertinent risk management program is implemented by private concessionaires, with the support of the government, then many risks could be mitigated, thus reducing the exposure of both the private sponsor and the government. Thus, in this study, we suggest a three-step risk management process. This first step of this process consists of identifying and classifying the risks in toll roads, according to the milieu from which they stem (project, market, country); the second step is an investigation in an array of risk mitigation strategies that are relevant to one or more risk categories; finally, the third step is risk analysis which consists of accounting for risks when evaluating a project. In the last two chapters, we will embody major issues in risk management in two case studies: In the first case study, New Batinah Highway project, we focus on the value of flexibility in toll roads and in the second case study, Melbourne City Link project, we focus mainly on the role of project organization and financial structure in risk management. Finally, in the conclusion, we emphasize that the private sponsor cannot be the only player in the risk management process but government support and commitment are vital. Thus we redefine the role of the government and the role of the private concessionaire in the provision of toll roads.

Texte intégralRésumé :
The risk analysis process involving information acquisition, modeling, analysis, and decision steps result in system design improvement. To allow an accurate and active system risk assessment in road transportation, this study identifies the contributing factors in reliability of road transportation systems and develops the systematic and stochastic methodologies and mathematical models. The developed models and methodologies aim to assess the reliability and risk of drivers interacting with the today’s typical vehicles equipped with Advanced Drivers Assistance System (ADAS) and Passive Safety Systems (PSS) with any degree of complexity and availability of such systems. The research further examines and addresses the specific needs of such vulnerable users and perhaps risk to others on roads including older drivers, younger drivers and pedestrians. The research presents the conditions monitoring concepts as in-vehicle tools for live assessment of risk state of drivers built on the methodologies and models developed in the studies. The necessity for availability of good data and specific databases for purpose of risk assessment in road transportation is then highlighted and stressed. The complete procedure for accident investigation and data collection is developed and presented in the research and a conceptual model for a typical human centered reliability databases in road transportation is also developed. The research is novel and innovative and expected to pave the way for improvement and development of new risk mitigating systems and better assessment and monitoring of the safety of users on roads and with the capability of information sharing resulting in saving many lives worldwide.

Texte intégralRésumé :
Transportation agencies report the localization of roadway anomalies that could cause serious hazards to the traveling public. However, the high cost and limitations of present technical prevent scaling the road monitoring to all roadways. Especially the unpaved road, because of the complexity of unpaved road. Using smartphone application as road condition data collection tool offer an attractive alternative because of its potential to monitor all roadways in real time and its low cost. However, the sensor sensitivity and sampling frequency of different smartphones may vary significantly, which challenge the confidence of using smartphones for actual pavement condition assessment applications. This study tends to solve this challenge by calibrating different smartphones using two different calibrating methods including calibrating towards reference or average road roughness.

This report describes the design of the Ina Road Landfill Stormwater Management System. Such a system is required by the Arizona Department of Environmental Quality to efficiently and safely remove stormwater drainage from the landfill to better protect the environment and the public during storm events. Stormwater drainage systems are required at landfills to efficiently collect and remove stormwater, limit moisture that can penetrate waste, protect the integrity of the buried mass and the final cover system from washing out and reduce risk of flooding to neighboring property. The State requires that landfill stormwater management systems be designed to handle a minimum size storm event based on historical precipitation records.

Hu, Yazhe. « Degenerate Near-planar Road Surface 3D Reconstruction and Automatic Defects Detection ». Diss., Virginia Tech, 2020. http://hdl.handle.net/10919/98671.
Texte intégralRésumé :
This dissertation presents an approach to reconstruct degenerate near-planar road surface in three-dimensional (3D) while automatically detect road defects. Three techniques are developed in this dissertation to establish the proposed approach. The first technique is proposed to reconstruct the degenerate near-planar road surface into 3D from one camera. Unlike the traditional Structure from Motion (SfM) technique which has the degeneracy issue for near-planar object 3D reconstruction, the uniqueness of the proposed technique lies in the use of near-planar characteristics of surfaces in the 3D reconstruction process, which solves the degenerate road surface reconstruction problem using only two images. Following the accuracy-enhanced 3D reconstructed road surface, the second technique automatically detects and estimates road surface defects. As the 3D surface is inversely solved from 2D road images, the detection is achieved by jointly identifying irregularities from the 3D road surfaces and the corresponding image information, while clustering road defects and obstacles using a mean-shift algorithm with flat kernel to estimate the depth, size, and location of the defects. To enhance the physics-driven automatic detection reliability, the third technique proposes and incorporates a self-supervised learning structure with data-driven Convolutional Neural Networks (CNN). Different from supervised learning approaches which need labeled training images, the road anomaly detection network is trained by road surface images that are automatically labeled based on the reconstructed 3D surface information. In order to collect clear road surface images on the public road, a road surface monitoring system is designed and integrated for the road surface image capturing and visualization. The proposed approach is evaluated in both simulated environment and through real-world experiments. The parametric study of the proposed approach shows the small error of the 3D road surface reconstruction influenced by different variables such as the image noise, camera orientation, and the vertical movement of the camera in a controlled simulation environment. The comparison with traditional SfM technique and the numerical results of the proposed reconstruction using real-world road surface images then indicate that the proposed approach effectively reconstructs high quality near-planar road surface while automatically detects road defects with high precision, accuracy, and recall rates without the degenerate issue.Doctor of Philosophy
Road is one of the key infrastructures for ground transportation. A good road surface condition can benefit mainly on three aspects: 1. Avoiding the potential traffic accident caused by road surface defects, such as potholes. 2. Reducing the damage to the vehicle initiated by the bad road surface condition. 3. Improving the driving and riding comfort on a healthy road surface. With all the benefits mentioned above, it is important to examine and check the road surface quality frequently and efficiently to make sure that the road surface is in a healthy condition. In order to detect any road surface defects on public road in time, this dissertation proposes three techniques to tackle the road surface defects detection problem: First, a near-planar road surface three-dimensional (3D) reconstruction technique is proposed. Unlike traditional 3D reconstruction technique, the proposed technique solves the degenerate issue for road surface 3D reconstruction from two images. The degenerate issue appears when the object reconstructed has near-planar surfaces. Second, after getting the accuracy-enhanced 3D road surface reconstruction, this dissertation proposes an automatic defects detection technique using both the 3D reconstructed road surface and the road surface image information. Although physics-based detection using 3D reconstruction and 2D images are reliable and explainable, it needs more time to process these data. To speed up the road surface defects detection task, the third contribution is a technique that proposes a self-supervised learning structure with data-driven Convolutional Neural Networks (CNN). Different from traditional neural network-based detection techniques, the proposed combines the 3D road information with the CNN output to jointly determine the road surface defects region. All the proposed techniques are evaluated using both the simulation and real-world experiments. Results show the efficacy and efficiency of the proposed techniques in this dissertation.

Texte intégralRésumé :
It has been known for some time that police records collected by the Department of Transport could be unreliable. Local Authorities use these data as an aid to the decision making process and to assist with objective setting. Studies warning of deficiencies in the accuracy of Stats 19 police data show confusing and often differing levels of inaccuracy. Due to the atypical nature of Road Traffic Accident typology the thesis sets out to examine a methodology for use by professional safety practitioners in order to test the reliability and accuracy of existing data and to test how in an operational environment these data might be expanded to meet the needs of the practitioner responsible for education, training and publicity measures rather than the pure highway engineering function which exists at the present time. Saunders, in 'Road Safety Management in a shire county' showed how tactical objectives were set by safety practitioners but concluded that operational resource planning was a vital stepping stone between the tactical and operational objective setting phase. The thesis examines this aspect in depth from a theoretical backcloth but illustrates throughout how this is-necessary to improve management efficiency and effectiveness within a public sector organisation. The thesis examines the levels of under-reporting in the local area from a management standpoint and considers the effects this information will have on the organisation. At the same time, aids to accident analysis such as statements made to the police and methods for improving the quality and reliability of data collection in an operational setting are considered. From this, the thesis examines the current and a proposed revision of the resource base and considers how these findings affect the operational resource plan for the organisation. This, and the methodology discussed, is a necessary management consideration if it is to enable an organisation to meet its aims and objectives.

This thesis describes the design, implementation, and execution of the Linear Road benchmark for stream-based data management systems. The motivation for benchmarking and the selection of the benchmark application are described. Test harness implementation is discussed, as are experiences using the benchmark to evaluate the Aurora engine. Effects of this work on the evolution of the Aurora engine are also discussed. Streams consist of continuous feeds of data from external data sources such as sensor networks or other monitoring systems. Stream data management systems execute continuous and historical queries over these streams, producing query results in real-time. This benchmark provides a means of comparing the functionality and performance of stream-based data management systems relative to each other and to relational systems. The benchmark presented is motivated by the increasing prevalence of "variable tolling" on highway systems throughout the world. Variable tolling uses dynamically determined factors such as congestion levels and accident proximity to calculate tolls. Linear Road specifies a variable tolling system for a fictional urban area, including such features as accident detection and alerts, traffic congestion measurements, toll calculations, and ad hoc requests for travel time predictions and account balances. This benchmark has already been adopted in the Aurora [ACC⁺03] and STREAM [MWA⁺03] streaming data management systems.

Texte intégralRésumé :
Mestrado em Engenharia Eletrónica e TelecomunicaçõesIn today's world, connectivity is an important requirement for the population. People want and, in a broad range of cases, need to be connected with each other and with the world. To share a video, attend an e-meeting or just keep in touch with friends and family, Internet is truly part of our everyday life. However, this massive growth of the connected world presented a lot of challenges to the engineering task-forces and research teams in computer networks. One of these challenges is mobility. The network mobility theme is not a recent matter in the networking world since people want to reach the Internet everywhere and still be able to do it like when at home. Several solutions have been presented and applied over the years; however, with the expansion of vehicular networks, new solutions must be presented in order to ful ll the requirements of such networks. In this work a study on the available mobility management solutions is performed. The studied mobility management solutions include both centralized and distributed solutions; however, the focus of the work presented is in the distributed category. In this context an implementation for a new distributed mobility management protocol, DMIPA, suitable to be used in a vehicular environment is presented. This new protocol aims to deliver mobility management in a distributed way, avoiding the disadvantages of centralized solutions, even in networks that do not provide any support for mobility without any hardware or network changes. Moreover, the protocol was tested in laboratory and on the road in order to acquire real data about the performance and behaviour of the implementation. These tests were based on the access technologies IEEE 802.11g, commonly used in WiFi access points, and IEEE 802.11p, a technology tailored for vehicular networks.
Actualmente, a conectividade ubíqua é uma necessidade importante para a generalidade da população. As pessoas querem e, em muitos casos, têm a necessidade de estar ligadas entre si e com o mundo. Para partilhar um vídeo, participar numa reunião online ou apenas para manter contacto com os amigos e familiares, a Internet faz verdadeiramente parte do nosso dia-a-dia. No entanto, este crescimento maciço do mundo online apresentou uma série de desafios às equipas de engenharia e investigação em redes de computadores. Um desses desafios é a mobilidade. O tema da mobilidade na rede não é uma questão recente, uma vez que as pessoas desejam aceder à Internet em todos os lugares e querem poder fazê-lo como se estivessem em casa. Várias soluções foram apresentadas e aplicadas ao longo dos anos; no entanto, com a expansão das redes veiculares, novas soluções são necessárias de modo a cumprir os requisitos de tais redes. Neste trabalho foi realizado um estudo sobre as soluções de gestão de mobilidade disponíveis. As soluções de gestão de mobilidade estudadas incluem soluções centralizadas e distribuídas; no entanto, o foco do trabalho apresentado está nas soluções distribuídas. Neste contexto, é apresentada uma implementação de um novo protocolo de gestão distribuída de mobilidade, DMIPA, adequado para ser utilizado num ambiente veicular. Este novo protocolo pretende aplicar a gestão da mobilidade de forma distribuída pelos vários nós da rede, evitando as desvantagens de soluções centralizadas, mesmo em redes que não oferecem qualquer apoio à mobilidade, sem quaisquer mudanças de hardware ou de rede. Além disso, o protocolo foi testado em laboratório e na estrada, a fim de obter dados reais sobre o seu desempenho e comportamento. Este teste foi realizado utilizando as tecnologias de acesso IEEE 802.11g, utilizado em pontos de acesso Wi-Fi, e IEEE 802.11p, uma tecnologia desenvolvida em especial para redes veiculares.

This study focuses on the current practice of health information management and its effectiveness in Oman. It investigates the factors driving the direction of future practice and their impact on the quality of health information, HIM employees and the Ministry of Health as a whole. It applied an exploratory sequential mixed-methods design through three integrated studies: focus groups, interviews and survey. The consolidated research data in this thesis identified a widespread misunderstanding of the HIM concept and confusion in regard to its function and importance. The research generated a framework for understanding the factors and their relationships to each other and to improved health system outcomes, which may guide the future development of HIM practice and make a major contribution to international knowledge within the discipline of health information management.

Texte intégralRésumé :
Today there are shortcomings in monitoring, control, analyses, learning and reporting of the results of activities and operations in the road management processes. There are also shortcomings in transparency and verifiability, in knowledge of road management’s costs and life cycle costs, of the road capital’s standard and condition and in measures of quality deficiency costs, productivity and maintenance backlog. The starting points for different applications of the model are taken from experience of the subprocesses in practical road management, independent analyses of activities, operations and results, presence at directors’ meetings (in an independent co-opted capacity) and literature reviews. It is my belief that the problems can largely be solved with transparent, verifiable information that is relevant to the sub-processes. A model has been designed with the transport policy’s requirements at the focus for all sub-processes’ applications without repeating errors as regards internal control, use of standard values and index adjustments. For each component, the model provides quality-related information about its current condition and condition value, acquisition value, replacement value and standard target value with the effects of measures carried out. Changes in standard and condition of new construction, improvements, maintenance and consumption can be shown in the model. Information can also be found on a component’s consumption cost, index adjustment and successively accumulated life cycle costs. Quality deficiency costs, inefficiencies, maintenance backlog, cost drivers, productivity and, for example, expected funding needs can be calculated by computer. The model has been tested and this document also describes the model’s implementation project at the SNRA. Most of the road network’s components have been registered for a long time in the SNRA’s road and traffic data bank as compulsory or optional phenomena. The remaining components will to a large extent be entered automatically. Some will require inventorying. In theory, the quality-related accounting will thus have access to information about every individual component in the entire state-administered road network. For at least 75% (80% in the implementation project) of the total value o fthe road capital, current condition information will exist for each individual component in the road network. The information, that constitutes “best available knowledge” of the components’ current functional condition, is administered in dedicated administration systems and comes from different kinds of inventories. The values of the remaining components can be appraised systematically on the basis of individually assessed technical length of life and, for example, planned maintenance. The model shows that decisions to carry out measures can also be based on “best available knowledge” of socioeconomic effectiveness, consideration of the environment, climate and energy in a life cycle perspective, customers’ (society’s and road-users’) expectations and political demands for fairness. These requirements are systematically worked into the limit values for “as constructed” and “worst acceptable condition”. The condition interval between the limit values shows the component’s functional consumption margin provided that the transport policy’s requirements are taken into consideration. The information makes it possible to consider and stipulate requirements regarding the development of components’ accumulated life cycle costs in procurements. Contractors will have a natural focus on increased productivity and cost increases in projects should be smaller. The model makes the long term planning process more efficient and shortens lead times. Prices, costs, accumulated life cycle costs and various types of deviations can be analysed continuously to achieve systematic learning from good examples and failures. In the project follow-up, deviations are automatically divided within the system into causes dependent on time, quantity, and unit price. Control and monitoring with analyses and learning can be made more effective through automatic monitoring against control limits. The concept of quality-related accounting of road capital should be a part of the international discussion around models for Transportation Asset Management (TAM).QC201007723

Texte intégralRésumé :
Understanding the impacts of roads on wildlife and the natural environment is of increasing importance, especially in the context of widespread urbanisation. Macropods (mostly kangaroos and wallabies) are a diverse and widespread taxon in Australia that has been significantly affected by the presence of roads in various ways. Although a moderate volume of research has been conducted on the interactions between macropod species and roads in Australia, this a fraction of the research effort conducted on large mammals in Europe and North America. Research that encompasses a variety of aspects of interactions between roads and macropods (and wildlife in general) is needed to broaden our perspective on impacts and mitigation.
Patterns of wallaby road mortality were investigated in a per-urban area of South East Queensland. Wallaby road-kill rates varied greatly; between 0.044 and 0.883 road-kills km-1 month-1 at the road or road section scale. Four wallaby mortality hotspots and several other areas of high mortality density were identified from the kernel density spatial analysis. Percent of commercial vehicle traffic (positively correlated) and distance to water (negatively correlated) were important spatial variables for determining the patterns of red-necked wallaby road-kill. Cumulative rainfall over the previous four weeks and maximum wind gust speed (both negatively correlated) were important temporal variables in determining the patterns of red-necked wallaby road-kill. Too few swamp wallaby road-kills were observed to be analysed.Thesis (PhD Doctorate)

Texte intégralRésumé :
Roads are an important part of the infrastructure of any country, as they facilitate the transportation of goods and people. The UK has got a good road network but has a low motorway density compared to other European countries. The High-ways Agency has a programme to improve the road network, mainly to ease con-gestion. To ensure the sustainability of road projects the UK government has set guidelines and standards that have to be met. These are the criteria used to ap-praise road projects for which EIA is a significant input. This paper seeks to find the connection between the transport appraisal objectives and post-EIA monitor-ing. The study was carried out by reviewing EIS and CEMP documents of three road projects in England. A short questionnaire with open questions was also ad-ministered. The results show that monitoring of impacts associated with the re-spective projects was mainly proposed during the construction phase, and for en-vironmental impacts. Social and economic impacts are generally not monitored during and after construction. Whilst post-EIA monitoring of impacts is seldom carried out, monitoring depends on the type of project, construction involved and the location of the project. More research is required in different kinds of projects, and more needs to be done to enforce ongoing monitoring after the EIA to sup-port the POPE exercise.

The South African government monitors and tracks the health of newborns and the growth of children. The Department of Health (DoH) does this monitoring using the Road to Health Booklet (RtHB). In this dissertation I analyse the use of the booklet in the township of Masiphumelele in Cape Town. The state produced booklet is intended for the child and mother as a patient-held medical health record. Liaw (1993) defines a patient-held record as notes or space provided on a document for the recording of follow up appointments for further investigation by medical doctors. The RtHB is used to record the child’s development, immunisations and HIV related information from birth to the age of twelve years. The dissertation results from ethnographic research with eight black Xhosa1 mothers and caregivers with children under the age of five years old. Mosley, and Chen, (1984), argue that in developing countries where standard child healthcare has been made available, children should survive the first five years of life. In my research, during the period of six weeks between July, August and September 2017, I followed the booklet in to Masiphumelele. From my observation and semi-structured interviews, looking at the state’s role of ‘pastoral’ care, child wellbeing and living in a township, and recording, under the theme of child wellbeing, certain concepts emerged. These concepts were state power, mothering, caring for children, responsibilisation, gender, kinship, fatherhood, child wellbeing knowledge production, social networking. In this dissertation I use ethnographic findings, accompanied by my own personal narratives. I argue that tracking child wellbeing through this booklet, the state exercises what Foucault (1982) referred to as ‘pastoral power’ in ensuring the wellbeing of the populations.

Texte intégralRésumé :
When a pile of scrap at Stena recycling has reached the maximum height, the loader operators need to drive around the facility to check whether or not the pile has to be emptied. This causes a lot of unnecessary driving, resolving in wear to the loaders and loss of time, but mostly the unnecessary use of diesel. In this paper different sensors is evaluated and tested against each other to find a system that can measure the volume of the pile. The sensors used is IFM O3D303 and the Kinect V1 sensor. These sensors are then used with two different volume calculation software, CloudCompare and 3DF Zephyr. The goal of the project is to get a system that can get a volume with an accuracy within 2.5 % of the actual volume. If a volume can be calculated from the scrap piles, then it is also possible to know when the pile should be cleared. Since the facility is a recycling plant, there is a lot of metal dust that is gathering in the indoor part of the facility. The sensors being used, should be able to work in this environment. To do that the sensor needs to have an IP certification higher than IP 55. The distance of measuring the pile can be more than 10 m, so the sensors should also be able to handle this requirement. From the sensors a point cloud and a mesh were captured, two data formats that contain information of where every point on the object is located in a three-dimensional space. Every system needs to be calibrated to suit the specific application. The results show that, even with a basic sensor such as the Kinect V1, an accurate volume of a scrap pile could, with calibration, be calculated. However, the cheap sensor does have limits, unlike the IFM which can cope with all the requirements. This report shows how the two sensors compare to each other and how the different software, combined with the sensors, can be used to calculate a volume of a pile of scrap.

Texte intégralRésumé :
Erosion from forest roads is a known problem in mountainous terrain. To abate these negative consequences, physical Best Management Practices (BMPs) are implemented, sometimes with no knowledge of erosion hot spots. With the need to minimize water quality impacts while at the same time accounting for multiple considerations and constraints, road BMP planning at the watershed scale is a difficult task. To assist in this planning process, a methodology is presented here that combines WEPP: Road erosion predictions with simulated annealing optimization. Under this methodology, erosion predictions associated with BMP options for a segment comprise the objective function of an optimization problem. This methodology was tested on a watershed in the Lake Tahoe Basin. WEPP: Road input data was gathered through road surveys. Modeling results predicted relatively little sediment leaving the forest buffer, as a result of numerous well-maintained BMPs and the dry climate found in the watershed. A sensitivity analysis for all WEPP: Road input parameters is presented, which provides insight into the general applicability of these erosion estimates as well as the relative importance of each input parameter. After evaluating erosion risk across the entire watershed, applicable BMPs were assigned to problem road segments and WEPP: Road was used to predict change in sediment leaving the buffer with BMP implementation at a given site. These predictions, combined with budget constraints as well as equipment scheduling considerations, were incorporated into an algorithm using simulated annealing as its optimization engine. Three modeled scenarios demonstrate the viability of this methodology in reducing total sediment leaving the road buffer over a planning horizon. Of the 173 segments surveyed, 38 segments could be treated using generic BMPs. For all three scenarios, BMP-SA reduced sediment leaving the buffer by as much as 70% over the course of a 20-year planning horizon. For the 38 segments treated with BMPs, sediment was reduced by greater than 90% over the planning horizon. This methodology is a viable approach for streamlining watershed-scale road network BMP planning, despite its heavy reliance on road erosion estimates.

Animal monitoring devices are deployed by the Department of Conservation (DOC) in remote areas. Currently this requires field workers to visit each device on a regular basis, which is costly and time consuming. This report details wireless technologies that would allow remote monitoring of these devices to bring about increased operational efficiency for DOC. Of particular interest is the wireless transmission of images through forested terrain.
While traditionally recognised as a difficult environment for wireless communications, research undertaken has indicated transmissions at 27 MHz are capable of achieving the feat. Development of a working system is greatly reduced through the use of Slow Scan Television technology; however justification for the system requires further study into particular case studies.

Texte intégralRésumé :
Monitoring systems represent an important tool to support efforts aimed at improving productivity and quality, reducing waste and enhancing safety in manufacturing. Modern technologies including electronic devices, communication technology, the Internet, database systems and modern computer technology represent resources that can provide flexible and cost accessible attractive and efficient solutions for the implementation of distributed and intelligent monitoring systems. A new generation of microcontrollers offer a high level of integrated devices and operate at low power, making them the ideal choice for many embedded industrial applications. However, the development of application software for microcontroller- based implementations has normally been a restrictive factor. Before this work this has resulted in most process and condition monitoring systems being PC based. This research presents an intelligent and distributed monitoring system based on microcontroller technology, specifically the PIC18C452. The system uses a flexible architecture that can be adapted to the necessities of different monitoring applications. "Monitoring Modules" that can be deployed according to the application requirements were developed. Industrial networks and Internet technologies are employed to enhance communication, therefore allowing monitoring records to be made available in a remote database. The Petri-net concept is used to represent the monitoring task in such a way as to provide independence from the system's hardware and software. Extensions to the original Petri-net theory and new modelling elements, including the acquisition of analogue signals, required to support the use of this method in a microcontroller-based environment, are presented. These enhancements represent a major contribution of this research. Finally, the benefits of the system are considered by means of three application examples a simple Press Rig to illustrate the general features and use of the system, a more complicated Assembly Process Rig to show the flexibility of the modelling approach, and finally a CNC Milling Machine tool changer is used to demonstrate the system in a real manufacturing application.

A new method for the monitoring of filament lamps and low pressure discharge lamps has been developed. The new technique monitors the electrical characteristics of the lamp to provide real time analysis of the lamp's condition, without the need for additional wires or expensive light sensors. The advent of low-cost microcontrollers developed for electrical metering applications means that not only is this technique technologically practical, it is also financially viable. The deployment of this technology, particularly in the case of UV water sterilizers, would improve safety and save the significant expense and environmental impact of unnecessary replacement lamps.

Texte intégralRésumé :
The sport of cricket is challenged by three formats of the game; each with varying workload demands. The most recent format is T20 cricket, first played internationally in 2005. Further to this, elite performers are often required to play for upwards of four different professional teams across the year; increasing the complexities in player workload management and other sports science-related support. Fast bowlers have greater overall match-play demands than other playing positions in cricket. Wearable microtechnology for tracking external load in athletes is common practice. Despite microtechnology enabling meaningful analyses of workload beyond routinely reported metrics, little application has occurred within fast bowling. The high injury risk in fast bowlers is well established, yet the intensive demands on these athletes remain poorly understood. The overall aim of this program of research was to use scientific literature to first understand the interaction of workload, injury and performance in elite level fast bowlers and then improve the understanding of workload management using advances in wearable microtechnology. The program of research in this thesis “with publication” first generated studies identifying the problem (a systematic review). The four subsequent chapters of original research built on the review to profile the match-play and training demands of cricketers, explore the variability of wearable microtechnology outputs during fast bowling, and finally develop and quantify an innovative means to monitor and manage workload within the specific demands of fast bowling in cricket. Although monitoring acute and chronic workloads of fast bowlers remains the most ideal method for identifying preparedness and injury likelihood in fast bowlers, complexities exist that make the systematic prescription of bowling workloads difficult. The results confirmed that the external load of cricket match-play and training varied between fast bowlers and non-fast bowlers. Furthermore, external loads experienced by 26 elite performing cricketers differentially affected the neuromuscular, endocrine, and perceptual fatigue responses of these players. Outputs from wearable microtechnology provided adequate stability across the performance of elite fast bowlers. These outputs were comparable with routinely used measures of fast bowling performance and intensity. Algorithms linking microtechnology outputs demonstrated good sensitivity in detecting fast bowling events in elite cricketers across competition (99.5%) and training (99.0%). The specificity of detecting fast bowling events decreased in competition (74.0%) however, remained high during training (98.1%). With the ability to automatically detect fast bowling events, metrics of bowling intensity can be explored more rigorously. Outputs from the gyroscope and accelerometers in the wearable technology provided strong associations with prescribed bowling intensity. Collectively, this thesis has highlighted the challenges of applied research in cricket, and more specifically the capacity to more objectively monitor external load in cricket fast bowlers.

Texte intégralRésumé :
Les mesures de trafic permettent aux opérateurs de réseaux de réaliser plusieurs applications de surveillances telles que l’ingénierie du trafic, l’approvisionnement des ressources, la gestion de réseaux, et la détection d’anomalies. Cependant, les solutions existantes présentent plusieurs problèmes, à savoir le problème de scalabilité, le problème de la détection des changements dans le trafic du réseau, et le problème de la perte d’informations significatives sur le trafic. La principale conséquence de cette tendance est un désaccord entre les solutions de surveillance existantes et les besoins croissants des applications de gestion des réseaux ; Ainsi, l’amélioration des applications de surveillance présente un défi majeur et un énorme engagement pour les grands réseaux. Ce défi devient plus difficile avec la croissance remarquable de l’infrastructure d’Internet, l’hétérogénéité des comportements des utilisateurs et l’émergence d’une large variété d’applications réseau. Dans ce contexte, nous présentons la conception d’une architecture centralisée adaptative qui fournit une visibilité sur l’ensemble du réseau grâce à un système cognitif de surveillance de son trafic. Nous considérons les exigences suivantes dans la conception de notre système de surveillance de réseaux. La première souligne le fait que les vendeurs ne veulent pas mettre en œuvre des outils d’échantillonnage sophistiqués qui donne nt de bons résultats dans certaines circonstances. Ils veulent mettre en œuvre des solutions simples et robustes qui sont bien décrites par une certaine norme (i. E. S’Flow, NetFlow). Ainsi, nous décidons de concevoir une nouvelle solution qui utilise des techniques de surveillance existantes et tente de coordonner les responsabilités entre les différents moniteurs afin d’améliorer la précision globale des mesures. La deuxième exigence stipule que le système de surveillance devrait fournir des informations générales sur l’ensemble du réseau0. Pour ce faire, nous adaptons une approche centralisée qui offre une visibilité sur l’ensemble du réseau. Notre système combine les différentes mesures locales en vue d’atteindre le compromis entre l’amélioration de la précision des résultats et le respect des contraintes de surveillance. Et la dernière exigence indique que le système de surveillance devrait régler le problème de scalabilité et respecter les contraintes de surveillance. Par conséquent, notre système repose sur un module de configuration de réseau qui fournit une solution réactive capable de détecter les changements dans les conditions du réseau et d’adapter la configuration des moniteurs à l’état du réseau. De plus, ils évitent les détails et les oscillations inutiles dans le trafic afin de garder la consommation des ressources dans les limites souhaitées. Le module de reconfiguration du réseau utilise des outils locaux de surveillance et ajuste automatiquement et périodiquement leurs taux d’échantillonnage afin de coordonner les responsabilités et répartir le travail entre les différents moniteursTraffic measurement allows network operators to achieve several purposes such as traffic engineering, network resources provisioning and management, accounting and anomaly detection. However, existing solutions suffer from different problems namely the problem of scalability to high speeds, the problem of detecting changes in network conditions, and the problem of missing meaningful information in the traffic. The main consequence of this trend is an inherent disagreement between existing monitoring solutions and the increasing needs of management applications. Hence, increasing monitoring capabilities presents one of the most challenging issues and an enormous undertaking in a large network. This challenge becomes increasingly difficult to meet with the remarkable growth of the Internet infrastructure, the increasing heterogeneity of user’s behaviour and the emergence of a wide variety of network applications. In this context, we present the design of an adaptive centralized architecture that provides visibility over the entire network through a net-work-wide cognitive monitoring system. We consider the following important requirements in the design of our network-wide monitoring system. The first underscores the fact that the vendors do not want to implement sophisticated sampling schemes that give good results under certain circumstances. They want to implement simple and robust solutions that are well described by some form of a standard (i. E. SFlow, NetFlow). Thus, we decide to design a new solution that deals with existing monitoring techniques and tries to coordinate responsibilities between the different monitors in order to improve the overall accuracy. The second requirement stipulates that the monitoring system should provide general information of the entire network. To do so, we adopt a centralized approach that provides visibility over the entire network. Our system investigates the different local measurements and correlates their results in order to address the trade off between accuracy and monitoring constraints. Ands the last requirement indicates that the monitoring system should address the scalability problem and respect monitoring constraints. To this end, our system relies on a network configuration module hat provides a responsive solution able to detect changes in network conditions and adapt the different sampling rates to network state. At the same time it avoids unnecessary details and oscillations in the traffic in order to keep the resulting overhead within the desired bounds. The network reconfiguration module deals with local monitoring tools and adjusts automatically and periodically sampling rates in order to coordinate responsibilities and distribute the work between the different monitors

The issue of effectively scheduling pavement maintenance and rehabilitation treatments over a multi-year planning horizon plagues road authorities around the world with the significance of this issue being amplified by both an ageing pavement network and the trend towards insufficient fund allocation. The scope of the problem can be quantified as follows: if only a single treatment is able to be applied to each individual road segment in a single year, then the total number of possible programmed maintenance and rehabilitation schedule alternatives for a moderate-sized network of 1,000 road segments, with eight different treatments possible, over a twenty year anaysis period is ((1.0 × 103)8)20 = 1.0 × 10480. Assuming that a computer can build and evaluate 100 complete maintenance and rehabilitation schedules a second, to identify the optimal schedule for this 1,000 segment road network would take 3.17 × 10471 years. The overall goal of this study is to investigate the benefits of applying modern heuristic optimisation techniques to the problem of pavement main- tenance and rehabilitation scheduling over a multi-year planning horizon. To address this goal, a four stage approach was utilised using a real road network with real pavement condition data as the test benchmark.Thesis (PhD Doctorate)

Texte intégralRésumé :
Lean Construction is regarded as an innovative approach of management for various types of projects in the field of construction. As much as it is currently applied in some countries, its expansion is inevitable, for better overall results are obtained and the projects’ objectives are met more precisely. Despite the fact that Lean Construction offers solutions to many problems occurring under the traditional management approach known as the Project Management (PM), the scope of its application is not as promising. Countries where Lean Construction is minimally applied include the United States of America and the United Kingdom besides other countries in Europe and Latin America. However, it is still not applied to a more exhaustive extent in these countries and is completely missing in many others around the world. This study primarily focuses on the application of Lean Construction to Infrastructure, specifically road projects; investigating Lean Construction solutions to the time wastes. Through conducting a case study research, this work focuses on investigating the impact of applying Last Planner System as a Lean Construction tool on the elimination of Non-Value Added (NVA) activities, that is, wastes in a highway project in Cairo, Egypt. This study includes a State of Art on both Project Management approach and Lean Construction. The study applies a comparative approach between the application of Project Management approach and Lean Construction in road projects. Hence, the researcher conducted different simulations of the studied road project, taking into account the two approaches (Project Management and Lean Construction), then obtaining the simulations results. Two parameters are used as comparison criteria: Percentage Plan Complete (PPC) and Percentage Activity Waste (PAW). The later (PAW) is a new parameter introduced by the researcher to investigate its results before/after applying the Lean Construction tools. Findings of the study support the research hypothesis that the application of Lean Construction approach to road projects enhances productivity through eliminating time-related wastes and decreasing the project duration. This research supports the argument that road projects can benefit greatly from the application of Lean Construction instead of the traditional approach.Lean Construction es considerado como un enfoque innovador para la gestión de diversos tipos de proyectos en el campo de la construcción. Por más que se aplique actualmente en algunos países, su expansión es inevitable, ya que se obtienen mejores resultados generales y los objetivos de los proyectos se cumplen con mayor precisión. A pesar del hecho de que Lean Construction ofrece soluciones a muchos problemas que ocurren bajo el enfoque de administración tradicional conocido como Gestión de Proyectos (Project Management, PM), el alcance de su aplicación no es tan prometedor. Los países en los que se aplica mínimamente el Lean Construction son los Estados Unidos de América y el Reino Unido, además de otros países de Europa y América Latina. Sin embargo, todavía no se aplica de manera más exhaustiva en estos países y está completamente ausente en muchos otros en todo el mundo. Este estudio se centra principalmente en la aplicación de el Lean Construction a Infraestructura, específicamente en proyectos viales; Investigando soluciones de Lean Construction para los desperdicios del tiempo. A través de la realización de una investigación de estudio de caso, este trabajo se enfoca en investigar el impacto de la aplicación del Sistema Last Planner como una herramienta Lean Construction en la eliminación de actividades sin valor agregado (NVA), es decir, desechos en un proyecto vial en El Cairo, Egipto. Este estudio incluye un estado del arte tanto en el enfoque de gestión tradicional de proyectos Project Management como en Lean Construction. El estudio se aplica a un enfoque comparativo entre la aplicación del enfoque de el Project Management y el Lean Construction en proyectos viales. Por lo tanto, el investigador realizó diferentes simulaciones del proyecto de carretera estudiado, teniendo en cuenta los dos enfoques (Project Management y Lean Construction), y luego obtuvo los resultados de las simulaciones. Se utilizan dos parámetros como criterios de comparación: Plan de porcentaje completado (PPC) y Porcentaje de residuos de actividad (PAW). El último (PAW) es un nuevo parámetro introducido por el investigador para investigar sus resultados antes / después de aplicar las herramientas de el Lean Construction. Los hallazgos del estudio apoyan la hipótesis de la investigación de que la aplicación del enfoque de Lean Construction a los proyectos viales aumenta la productividad al eliminar los desechos relacionados con el tiempo y disminuir la duración del proyecto. Esta investigación apoya el argumento de que los proyectos viales pueden mejorarse en gran medida con la aplicación de el Lean Construction en lugar del enfoque tradicional el Project Management.

Texte intégralRésumé :
This Ph.D. dissertation focuses on optimizing automated decision-making processes involving critical aspects of road management tasks. Specifically, the research aims to define and implement specific strategies for supplying support to decision-makers considering two leading elements: road maintenance and road safety. We propose some novel applications based on the integrated use of high-performance Non-Destructive Techniques (NDTs) and Geographical Information Systems (GISs) in order to obtain a “fully sensed” infrastructure, creating a multi-scale database concerning structural, geometrical, functional, social, and environmental characteristics. The environmental aspect is essential since climate change phenomena and extreme natural events are increasingly linked with infrastructure damage and serviceability; nonetheless, current Pavement Management Systems (PMSs) commonly rely solely on road pavement structural characteristics and surface functional performance. The high amount of collected data serves as input for calibrating different data-driven approaches, such as Machine Learning Algorithms (MLAs) and statistical regressions. Considering the aspect of road monitoring and maintenance, such models allow identifying the environmental factors that have the most significant impact on road damage and serviceability, as well as recognizing road sites with critical health conditions that need to be restored. Moreover, the calibrated MLAs enable decision-makers to determine the road maintenance interventions with higher priority. Considering road safety, the calibrated MLAs allow identifying the sites where serious road crashes can be triggered and estimating the crash count in a specified time frame. Moreover, it is possible to recognize infrastructure-related factors that significantly impact crash likelihood. Road authorities may consider the outcomes of the dissertation as a novel approach for drafting appropriate guidelines and defining more objective management programs.

M. Tech. (Information Technology, Faculty of Applied and Computer Sciences), Vaal University of TechnologyTraffic congestion is a concern within the main arteries that link Johannesburg to Pretoria. In this study Matlab function Randperm is used to generate random vehicle speeds on a simulated highway. Randperm is used to mimic vehicle speed sensors capturing vehicle traffic on the highway. Java sockets are used to send vehicle speed to the Road Traffic Control Centre (RTCC)-database server through a wireless medium. The RTCC-database server uses MySQL to store vehicle speed data. The domain controller with active directory together with a certificate server is used to manage and provide security access control to network resources. The wireless link used by speed sensors to transmit vehicle speed data is protected using PEAP with EAP-TLS which employs the use of digital certificates during authentication. A java database connectivity driver is used to retrieve data from MySQL and a multilayer perceptron (MLP) model is used to predict future traffic status on the highway being monitored i.e. next 5 minutes from previous 5 minutes captured data. A dataset of 402 instances was divided as follows: 66 percent training data was used to train the MLP model, 15 percent data used during validation and the remaining 19 percent was used to test the trained MLP model. An excel spreadsheet was used to introduce novel (19 percent data not used during training) data to the trained MLP model to predict. Assuming that the spreadsheet data represent captured highway vehicle data for the last 5 minutes, the model showed 100 percent accuracy in predicting the four classes: congested, out congested, into congested and normal traffic flow. Predicted traffic status is displayed for the motorist on the highway to know. Ability of the proposed model to continuously capture the traffic pattern on the highway (monitor) helps in redirecting (controlling) the highway traffic during periods of congestion. Implementation of this project will definitely decrease traffic congestion across main arteries of Johannesburg. Pollution normally experienced when cars idle for a long time during congestion will be reduced by free highway traffic flow. Frequent servicing of motor vehicles will no longer be required by the motorists. Furthermore the economy of Gauteng and South Africa as a whole will benefit due to increase in production. Consumers will also benefit in obtaining competitive prices from organizations that depend on haulage services.
