Повний текст джерелаIntelligent Transportation systems (ITS) are massively used in the Public Transport sector since the Two decades. This profusion of systems on-board and off-board vehicles generates inter-operability issues. The growth of urban zones and the increase of public transport attractiveness, brought multi-modal constraints that are today limited due to a lack of architecture vision embracing all ITS. This thesis proposes to unify the architecture vision of on-board ITS. We based our technical architecture on the Service Oriented Architecture (SOA) proposed in the European Bus System of the Future (EBSF) project, in which this thesis actively contributed. We study first the global requirements of different transportation modes operated in Europe. Those requirements are a basis to the definition of technical constraints of a global architecture. Those constraints are ranked in terms of importance using a proposed method based on Multi-Criteria Decision Making (MCDM) techniques. The method that we propose permits to size the technical architecture. We then study the flow management of data, considering the context of operation of vehicles and the criticality of ITS applications. We propose to adapt the Real-time Mixed-Criticality model to communication systems on-board the vehicles. We apply this method on a communication gateway of a bus, through its journey. Finally we present the work done at the standardization level (CEN) in order promote the global architecture vision presented in the thesis

During the past two decades, Intelligent Transportation Systems (ITS) have provided transportation organizations with increasingly advanced tools both to operate and manage systems in real-time. At the same time, federal legislation has been tightening the linkages between state and local transportation investments and metropolitan air quality goals. In this context, ITS seems to represent a case of the potential synergies - or so-called "win-win" outcomes - that could be realized for the dual policy goals of air quality and mobility. If the various public sector organizations responsible for air quality and transportation could cooperate in deploying, assessing and further adapting these new technologies to take advantage of these synergies, they could achieve a "sustainable use" of ITS. However, looking beyond ITS and air quality, these issues point to broader questions of how to appropriately manage technology and its impacts on society, specifically those technologies deployed by the public sector. In particular, how does the public sector innovate and deploy technologies in ways that maximize the benefits, and minimize or avoid the negative impacts? In order to examine this phenomenon, this thesis takes the example of ITS and air quality to develop and test a broader framework of Integrated Innovation, Deployment and Adaptation of Public Technologies (IIDAPT).
(cont.) In this thesis, we define and articulate a framework for IIDAPT, and identify testable conditions that make IIDAPT either more or less likely to occur. We identify seven conditions - based in the literature of political science, organizational theory, and public administration - that should, in theory, influence the ability of public agencies to achieve synergies for multiple policy goals through technology deployment. Having developed a theoretical framework for the conditions that influence IIDAPT, we then test those conditions using five U.S. cities - Los Angeles, Houston, Boston, Orlando, and Tulsa - as case studies in ITS and air quality. We then extend the framework to a non-US case, Mexico City, in order to further test the IIDAPT framework and to identify possible changes at the federal and local level to better align ITS deployments with both mobility and air quality goals in Mexico City. This research explains some interesting outcomes in terms of failures by public sector agencies to take advantage of new, lower cost ITS technologies that can provide multiple benefits for both mobility and air quality. We find that "cheap" solutions, such as ITS rather than conventional infrastructure, are not always in an agency's interests, as defined by the agency.
(cont.) Specifically, we found that lower-cost innovations may compete with an agency's or elected official's priorities for certain categories of investment, by undermining the ability to build up the case for that investment. The overarching conclusion, is that the possibilities for synergies (or "win-win" outcomes) must be defined, not according to the stated policy objectives or mission of the public sector agencies, but according to the underlying interests and agendas of agencies, which may, or may not align with the public interest. We also found that new information on the impacts of new ITS technologies on air quality does not generally lead to adaptation in the application of those technologies either to reduce negative impacts or to provide additional benefits for air quality. Even where evaluations of air quality impacts were required, those assessments were not well integrated into the process of technology deployment and later adaptation in the use of those technologies. Indeed, new information that can change the perception of possible mutual benefits is not always welcomed by agencies, and assessment methodologies will tend to reflect existing agency preferences. However, there were reasons for optimism.
(cont.) We found that in response to an increasingly "severe" air quality problem (as defined by federal regulations), local agencies are in fact experimenting with the use of ITS to achieve air quality benefits as well as mobility benefits. Furthermore, by creating the Congestion Mitigation and Air Quality (CMAQ) program, a dedicated federal funding source for non-traditional transportation investments (such as ITS) with air quality benefits, agencies were provided with the resources and additional motivation to seek out and deploy ITS technologies with air quality benefits. To conclude this work, we highlight possible areas of future theory development for IIDAPT, and point to additional technology and policy domains where the IIDAPT framework can be applied and tested.

Struwig, Claudia Bernadine. "A stepwise approach towards achieving a multimodal platform within the context of the CoCT’s land transport networks." Thesis, Stellenbosch : Stellenbosch University, 2013. http://hdl.handle.net/10019.1/80001.
Повний текст джерелаENGLISH ABSTRACT: The importance of transport should not be underestimated. Transport progresses a person’s quality of life: it connects people to one another and provides access to work, services and recreational opportunities. However, post-apartheid South Africa is unfortunately still faced with a legacy of segregation. While the less-privileged, who mostly live at the fringe of Central Business Districts (CBDs), are captive users of public transport, the private vehicle trend, under the privileged, is becoming more evident. This research project thus proposes that a balanced and integrated sustainable transport system be promoted. That is, one that will aid South Africa in growing and improving its general socio-economical status by providing all its citizens with (equal) access to a balanced transport network. It is believed that, if a multimodal system is promoted, the deficiencies of the current heterogeneous non-integrated systems may be overcome. Therefore, if South Africa’s transport network is augmented with a multimodal platform, the nation will be able to move its citizens effectively and efficiently, without jeopardising the economy, social matters and the environment, today and in the future. Moreover, South Africa will also have the necessary stimulus to utilise the already available resources at its disposal by working together as ‘one’. This research project thus stipulates a (generic) sequential approach needed in achieving an integrated (sustainable) public transport system. The goal of this research project is to create awareness of the benefits that may arise from, and the implementation steps required in obtaining, such a multimodal platform. The focus area for researching the proposition made herein is the City of Cape Town’s (CoCT’s) land transport networks. The City has a management facility, with resultant transport data repository, known as the Transport Management Centre (TMC). This TMC is regarded as one of the finest state of the art facilities in the world and the features thereof offer a sufficient base and point of departure for the promotion of a multimodal transport system. By conducting research in this field, the following portraying aspects, needed for the realisation of the proposition made herein, were found. Firstly, in order to obtain an integrated sustainable transport system, the appropriate Intelligent Transport Systems (ITS) need to be integrated. It is believed that, if an intelligent transport scheme, grounded on ITS applications, is advocated, the City will be in the position to more effectively monitor what is going on, to more accurately predict what might happen in the future, and to manage its transport system proactively on an area-wide basis. Secondly, in order to meet the integration requirements imposed by multimodal transport, a centralised database needs to be created. With such a database in place, information sharing across all modes of private- and public land transport, and thus also between the investors or the operators, will be possible. An example of such a database was developed in Microsoft Access and the modes considered therein are: MyCiti, Metrorail and Golden Arrow Bus Service (GABS). The data stored in this database is historic, but the incorporation of real time information was also catered for. Thirdly, it is believed that the success of the City’s transport system, and the development of a multimodal system, is dependent on the provision of an efficient Advanced Traveller Information System (ATIS). The idea is to promote multimodal transport as a convenient transit option by providing travellers with information on journey planning that aims to counteract their reluctance to change. In order to develop such a multimodal Journey Planner (JP), the unimodal networks considered herein were combined into a supernetwork on which Dijkstra’s Shortest Path Algorithm was applied. This algorithm was programmed in Microsoft Excel’s Visual Basic for Applications (VBA) and it incorporates the following user criteria: the origin, the destination, the user’s mode preference, and the user’s optimisation preference of either time or distance. In conclusion, it can be argued that, with information becoming such a vital commodity in everyday life, the catering for informed travellers are the key to successful future transport services. If travellers are informed about the transport networks’ performance, a positive attitude is fostered. Moreover, by providing travellers with information on journey planning, their feelings of uncertainty and fear of the unknown, that are present in (especially) public transport services, may be neutralised. This information will give the public carte blanche to make decisions that give them the perception of having more ‘control over their lives’. Therefore, if a multimodal JP that can be accessed from one portal is created, people’s inclination to acquire more information will be met. And as a result, traversing in an integrated manner may become the norm.
AFRIKAANSE OPSOMMING: Die belangrikheid van vervoer mag nie onderskat word nie. Vervoer speel ’n belangrike rol in die bevordering van ’n persoon se lewenskwaliteit: dit verbind mense met mekaar en verskaf toegang tot die werksplek, diensteverskaffers, en vryetydsbesteding. Post-apartheid Suid-Afrika is egter nog steeds vasgevang in ’n nalatenskap van rasseskeiding. Die minderbevoorregtes, wat meestal aan die buitewyke van die stad woon, is geforseerde gebruikers van openbare vervoer, terwyl die neiging (onder die bevoorregtes) om privaatvoertuie te gebruik, aan die toeneem is. Hierdie navorsingsprojek beveel dus aan dat ’n gebalanseerde, geïntegreerde en volhoubare vervoerstelsel bevorder moet word. ’n Sodanige stelsel sal help om die sosio-ekonomiese status van Suid-Afrika te bevorder. Dít kan net bereik word as alle landsburgers gelyke toegang tot ’n gebalanseeerde vervoernetwerk het. As ’n multimode-stelsel dus bevorder word, kan die tekortkominge van die huidige heterogene, nie-geïntegreerde stelsels oorkom word. Indien Suid-Afrika se vervoernetwerk ’n multimodale platform het, kan die landsburgers effektief en doeltreffend vervoer word sonder om die ekonomie, sosiale aangeleenthede of omgewing, tans en in die toekoms, in gedrang in te bring. Suid-Afrika sal boonop, met so ’n platform in plek, ook die nodige stimulus hê om die bestaande hulpbronne optimaal te gebruik. Hierdie navorsingsprojek verskaf ’n (generiese) in-volgorde-benadering om ’n volhoubare, geïntegreerde openbare vervoerstelsel daar te stel. Die doel is om bewustheid van die voordele wat uit ’n multimodale platform spruit, sowel as die nodige stappe vir die uitvoering daarvan, te kweek. Die fokusarea van die navorsing is die Stad van Kaapstad se land-vervoernetwerke. Die Stad het ’n beheerfasiliteit waar vervoerdata versamel word. Dit staan bekend as die vervoer-beheersentrum (TMC: Transport Management Centre). Hierdie fasiliteit word as toonaangewend in die wêreld beskou. Die kenmerkende eienskappe van hierdie fasiliteit bied verder ook ’n goeie vertrekpunt vir die bevordering van ’n multimodale stelsel. Die navorsing in hierdie veld het die volgende bydraende faktore, wat benodig word om die voorstelling te realiseer, geïdentifiseer. In die eerste plek moet die intelligente vervoerstelsels (ITS: Intelligent Transport Systems) geïntegreer word om ’n geïntegreerde volhoubare vervoerstelsel daar te stel. Indien ’n intelligente vervoerskema, gebaseer op tegnologiese inisiatiewe, aangemoedig word, sal die Stad van Kaapstad in die posisie wees om sy vervoerstelsel pro-aktief te bestuur deur meer effektief te monitor wat aangaan en meer akkuraat te voorspel wat in die toekoms mag gebeur. Tweedens moet daar ’n gesentraliseerde databasis geskep word. Met hierdie databasis sal die nodige integrasievereistes vir ’n multimodale vervoerstelsel, bereik word. Inligting kan dan gedeel word tussen privaat- en openbare landvervoer, asook tussen die beleggers en die operateurs van die verskillende vervoermodusse. ’n Voorbeeld van so ’n databasis is in Microsoft Access geskep en die modusse wat deel daarvan uitmaak, is: MyCiti, Metrorail en Golden Arrow Bus Services (GABS). Die data wat hierin vervat is, is histories, maar daar is vir intydse inligting voorsiening gemaak. In die derde plek is die sukses van die Stad van Kaapstad se vervoerstelsel en die ontwikkeling van ’n multimodale stelsel afhanklik van die daarstelling van ’n effektiewe, gevorderde inligtingsstelsel vir pendelaars (ATIS: Advanced Traveller Information Systems). Die idee is om ’n multimodale vervoerstelsel as ’n gerieflike opsie onder pendelaars te bevorder. Dit kan bereik word deur inligting rakende reisbeplanning aan pendelaars daar te stel. Met die verkryging van sodanige kennis sal die pendelaar se weerstand teen verandering ook afneem. Om so ’n multimodale reisbeplanner (JP: Journey Planner) te ontwikkel, is die eenmodaal-netwerke gekombineer om ’n supernetwerk te skep. Dijkstra se algoritme is op die supernetwerk toegepas. Die algoritme is in Microsoft Excel se VBA (Visual Basic for Applications) geprogrammeer en dit bevat die volgende gebruikerskriteria, nl. die begin- en eindpunt, die gebruiker se modes-voorkeur en die gebruiker se gekose optimeringsvoorkeur van tyd of afstand. Ten slotte kan gesê word dat inligting ’n groot rol in die mens se daaglikse lewe en aktiwiteite speel. Daar kan dus geredeneer word dat die sleutel tot suksesvolle vervoerdienste daarin lê om vir ingeligte pendelaars voorsiening te maak. As pendelaars ingelig is oor die stand van die vervoernetwerk maak dit hul houding meer positief. Verder, as pendelaars ook inligting oor reisbeplanning het, kan dit hul gevoel van onsekerheid en vrees jeens (veral) openbare vervoer teenwerk. Met al hierdie inligting tot sy beskikking kan ’n persoon dus sy eie keuses maak en dit lei daartoe dat die persoon meer in beheer voel. As ’n multimodale JP geskep word, voed dit die mens se begeerte vir meer inligting. En met ’n sodanige JP in plek, kan geïntegreerde pendel moontlik die norm word.

Повний текст джерелаCities in the world aim to ensure the mobility of people, through the implementation of efficient Integrated Transportation Systems (ITS). This aims to improve the transport of people, which guarantees that they can be mobilized safely and without delays in the terminals and bus stops of the public transport system. The present article proposes a design of public transport stops aimed at optimizing the waiting time of users when transferring from one bus to another. For the validity of the proposal, the social force model of the Vissim program was used, where the behavior of the users within the bus stops was reflected. The results showed that the waiting times in the calibrated and validated microsimulation model were optimized by approximately 20%, which generates an improvement in the efficiency of the public transport system.

The Public Transportation Systems provides modern technology able to improve operation performance , comfort and safety for the costumers. This work intends to study the uses of Information Technology, its application and results as subsidy for planning and management of public transportation of passangers, predominantly fulfilled by bus. The basic hypothesis of this work is that the technological resources available are not used or are used inadequately by the managers and operators of the public transportation. The work invastigates what is known by quality on public transportation in literature and how it is conceived by the agents envolved: costumers, operators, managers and the community in general. This works shows, still, the basic concepts of Intelligent Transportation Systems, and the details and analysis of applications on public transportation, in special those regarding resources in Information Technology. The details of a survey that aimed to identify which technological resources are used by the organ managers of public transportation, in many city in Brazil, and that should be able to turn in improvements of quality of the system, completed the work. The result of this survey indicated that, even though there is a range of technologies available, the use of this potential is very small, and contributes little for the improvements of quality of the public transportation.
Os sistemas de transportes públicos dispõem de modernas tecnologias capazes de melhorar o desempenho da operação, o conforto e a segurança dos usuários. Este trabalho pretende estudar o problema do uso da Tecnologia da Informação, sua aplicação, e seus resultados como subsídio para o gerenciamento e planejamento do transporte público de passageiros, predominantemente realizado por ônibus. A hipótese básica do presente trabalho é de que os recursos tecnológicos disponíveis não são utilizados, ou são utilizados inadequadamente, pelos gestores e operadores do transporte público. O trabalho investiga o que se entende por qualidade no transporte público na literatura, e como é percebida pelos agentes envolvidos: usuários, operadores, gestores e a comunidade em geral. O trabalho apresenta, ainda, os conceitos básicos dos Sistemas Inteligentes de Transportes, e os detalhamentos e análises das aplicações no transporte público, em especial os referentes aos recursos da Tecnologia da Informação. O detalhamento de uma pesquisa que visou identificar quais os recursos tecnológicos são utilizados pelos órgãos gestores do transporte público, em diversas cidades do Brasil, e que pudessem se traduzir em melhorias da qualidade do sistema, completaram o trabalho. O resultado da pesquisa indicou que, embora exista uma gama de tecnologias disponíveis, a utilização desse potencial é muito pequeno, e pouco contribuem para a melhoria da qualidade do transporte público.

Повний текст джерелаENGLISH ABSTRACT: Mode choice modelling is an important and versatile tool that can aid decision makers with transit related strategies and scenario planning. The traditional approach to modelling public transport is labour intensive and requires many resources. The expensive nature of developing mode choice models can also act as a deterrent for developing a model. Not having access to a functional mode choice model can force decision makers to make important decisions without having access to proper information. There is therefore a need to provide a simplified solution for developing a functional mode choice model that can be developed and maintained with fewer resources. This research project explores the possibility of developing a simplified alternative approach to public transport modelling that can model mode choice behaviour with the same degree of accuracy as traditional models. The modelling steps employed in this research project were the typical four step demand modelling approach, but the principles employed differ slightly. The focus area of this research project is the development of simplified utility functions and the calibration thereof. Typical mode choice models coincide with many assumptions, variations and uncertainties. In this research project the proposed utility functions are simplified by incorporating most of the assumptions and intangible components of the utility function into a single station to station specific calibration factor. The hypothesis is that a simplified alternative approach to the utility functions can still provide a model that is purpose built and functional. The application of the proposed mode choice model is to model the mode choice between the Gautrain and private vehicles as the major mode of transport.

Повний текст джерелаThis dissertation proposes a technological model for automation for conducting surveys in the public transport sector, in order to contribute to the improvement of data collection, evaluation and maintenance of quality of services rendered to the population. The work is justified by the need to overcome gaps for obtaining information, which affects the management of the public transport system as a whole. Due to the increasing relevance of the issue of urban mobility and its impact on quality of life, the chosen object of study were the passenger movements through the bus use in the city of São Paulo. The proposed model integrates the radio frequency identification technology - RFID, on smart cards currently used to pay the fare, with fleet tracking technologies, which, through GPS (Global Position Systems), provide information on the bus traffic locations. The results show that this integration can solve the problems of lack of precision in data about where passenger trips are initiated and completed as well as make systematic withdrawals of such data without the need for manual searches, saving features. It is an innovative proposal with great use to expand the conditions that improve urban mobility and is convergent to the development of smart cities.

Повний текст джерелаNowadays, the technology to turn cities smart already exists. Smart Cities, as they are called, are capable to sense, analyze and react: sense through the set of sensors displaced along the city, as they are sensors either xed (for environmental monitoring) or moving (for instance, citizens with their smartphones). A notable case is Porto, which incorporates a mesh network with more than 600 vehicles (buses, taxis and garbage trucks), communicating in-between and enabling the passengers of the buses of the city major bus carrier to access freely to the Internet while commuting. A vehicular network like this has huge positive impact in the city mobility, which is one of the biggest concerns of the governmental institutions. Therefore, it is crucial to understand what can be done to improve mobility. By analyzing the data generated by the movement of the buses, it is possible to deliver a new set of tools that might be useful for the everyday life of the bus passengers and bus eet managers. From the passengers perspective, the utility can be brought by the introduction of smart schedules, which consists on delivering estimated time of arrival that is adapting itself to the city dynamics, through the evolution of the time, and that can be accessed directly from their smartphones. From the perspective of the bus eet managers, it is possible to deliver insights about the usual behaviour of their bus lines, giving openness for them to react to the new or abnormal city public transportation dynamics. This dissertation presents an approach for analyzing the data descendent from the vehicular network and how to use it to answer the previously addressed problems. Regarding the missing link between the GPS trace from the bus and the bus line that they are doing, a map-matching algorithm is implemented. That turns possible the computation of estimations and predictions of the bus' passing times. In what concerns prediction, three machine learning ensemble algorithms have been tested. Finally, proof-ofconcept applications are implemented to demonstrate the real-life applicability, by helping the bus passengers and bus eet managers to react to the di erent events of their quotidian. The results show that the map-matching algorithm presents a good quality. Also, they demonstrate that the best machine learning algorithm, considering the prediction error, is Bagging using Support Vector Regressor as the base estimator. Finally, the pro les obtained in the performance dashboard enable distinction between optimal and non-optimal bus lines.
Hoje em dia existe tecnologia para tornar as cidades inteligentes. As cidades inteligentes s~ao capazes de sentir, analisar e reagir: sentir através dos variados sensores espalhados em torno da cidade, sensores estes que podem ser fixos (sensores para a monitorização do estado ambiental) ou moveis (por exemplo, os cidadãos, graças aos seus smartphones). Um caso notável e o da cidade do Porto, que incorpora uma rede em malha com mais de 600 veículos (autocarros, táxis e camiões do lixo) que comunicam entre si, habilitando os passageiros dos autocarros da maior operadora da cidade a navegar na internet gratuitamente, enquanto viajam. O maior impacto de uma rede como esta e a mobilidade; e uma das preocupações das instituições governamentais locais e como elas podem melhorar a mobilidade. E por isso crucial analisar o que pode ser feito para melhorar a mobilidade de uma cidade. Utilizando os dados gerados pelo movimento dos autocarros e possível fornecer um conjunto de novas utilidades praticas que podem ser úteis ao quotidiano dos cidadãos e dos gestores de frota. Na perspectiva dos passageiros pode ser introduzido o conceito de smart schedule que consiste em fornecer o tempo estimado de chegada de um autocarro que se vai adaptando ao longo do tempo, de acordo com a dinâmica da cidade, que pode ser acedido directamente a partir do seu smartphone. Na perspectiva dos gestores de frota e possível fornecer introespecções sobre o comportamento habitual das linhas de autocarros, dando abertura a que estes sejam capazes de melhor reagir a novas ou anormais dinâmicas dos transportes públicos da cidade. Esta dissertação apresenta uma abordagem para analisar os dados provenientes da rede veicular e de como usa-los para tornar as ideias previamente esclarecidas, possíveis. Devido a inexistência da identificação do trafico GPS a uma linha de autocarro, um algoritmo de map-matching foi implementado. Isso torna a computação de estimações e predições sobre o tempo de passagem dos autocarros possível. No que toca a predição, foram testados três algoritmos diferentes de aprendizagem automática em conjunto para a construção de modelos preditivos. Porem, foram implementadas aplicações como prova de conceito que demonstram a aplicabilidade no mundo real, ajudando os passageiros dos autocarros e os gestores de frota a reagir aos diferentes eventos do seu quotidiano. Os resultados demonstram que o algoritmo de map-matching apresenta uma boa qualidade. Também demonstram que o melhor algoritmo de aprendizagem automática, considerando o erro de predição, e o Bagging utilizando como estimador base Support Vector Regressor. Porém, os pers obtidos pelo painel de controlo permitem distinguir linhas de autocarro com um funcionamento óptimo daquelas em que o funcionamento e insatisfação.

Повний текст джерелаLarge-scale integrated systems working collectively for a common mission are known as Systems of Systems (SoS). In the present work, we propose a modeling method for a class of SoS, namely mechatronic systems, based on the Bond graph modeling approach. The proposed approach is applied to an Intelligent Transportation System (ITS) by modeling the traffic dynamic of Intelligent Autonomous Vehicles (IAVs); where Vehicle to Vehicle (V2V) and Vehicle to Infrastructure (V2I) communications are considered. Such set of autonomous vehicles describe the organization of a SoS. The traffic dynamic is modeled at three abstraction levels namely: submicroscopic, microscopic, and macroscopic levels. Subsequently, the three levels are combined to develop a multilevel model of the traffic dynamic using the same Bond graph approach. The model is simulated for normal and faulty scenarios. Then, the model is validated on a real-time simulator of vehicle dynamics. In addition, real experiments on IAVs are performed to validate the model. Finally, the model is used to develop a supervision strategy for the traffic SoS based on the behavioral and structural analysis of the Bond graph model

Повний текст джерелаThis thesis demonstrates the benefits of using Graph Signal Processing (GSP) techniques for an intelligent taxis transportation system. Graph Signal Processing, an application arising to handle multiple source signals on a graph, has developed into an active field of research during the last several years due to its ability to analyze enormous datasets or dynamic data that usually pose a challenge to researchers. One of the most significant operations of Graph Signal Processing that arises in many areas is noise reduction.
This thesis introduces a possible method of using Graph Signal Processing and its operations to analyze signals in a network of taxi stand locations. Two examples are given using real data of taxis' and stands' locations in San Francisco where the number of taxis around these stands is the detected signal. The results showed the effectiveness of using Graph Fourier Transform to detect the anomalies in the signals which represent unusual transportation activities or driver distributions within the taxi network.
Signal denoising is addressed by using four techniques which are often based on the signal filtering methods. The first technique used the low pass filter, followed by a harmonic decline filter, and then standard and modified Kalman filters, including the case for uncertain observation or process noise between the standard and adaptive Kalman filters. The results are compared with the other filters.

Повний текст джерелаThe development of transportation all over the world has been providing a lot of benefits for many aspects of human life. Intelligent Transportation Systems (ITS) are advanced applications that aim to make the transport networks safer, more convenient and smarter. According to their usages, they can be classified into two types of ITS applications, which are safety applications and non-safety applications. Vehicular ad hoc network (VANET) is a key component of ITS since it enables communications among transportation units. These communications support different ITS applications with various properties. Between two types of applications, we are interested in safety applications which have tighter quality and security constraints. Depending on an applied scenario of a given safety application, the exchanged information among vehicles must be broadcast locally within one-hop communication and/or also be notified to vehicles in large range. The main objective of this thesis is to improve the performance of safety applications in term of the quality of service and security, in both one-hop communication and multi-hop communication. We focus on reliability, connectivity and Denial of Services (DoS) attack. We study and propose technical solutions coming from lower layers (Physical, MAC and network layers) which play a fundamental role in mitigation to challenges created by the nature of the vehicular environment. Firstly, we introduce a reliable scheme to achieve the reliability for broadcasting. In our scheme, the safety messages are rebroadcast when the sender is solicited. This increases the percentage of vehicles receiving the messages while duplicated messages are limited. Secondly, with consideration of the fragmentation of the network, we study solutions that overcome the temporary disconnection in the network to bring the safety information to the recipients. Based on the social properties of vehicular networks, we propose a social-based forwarding protocol to support the communication between vehicles to points of interest that provide safety services with looser time constraints, such as search and rescue. Thirdly, we investigate jamming attack, a kind of DoS attacks, which is crucial for safety applications because of the adequate condition of the attack at the lower layers. We model jamming attack on broadcasting in order to study the degradation caused by the attack on network performance. The degradation at a certain level in network performance is an indication of a jamming attack presence in the network; therefore results from this analysis will allow us to determine network performance thresholds to distinguish between normal and attacked scenarios. However, according to our analysis, the method using the degradation as an indication to detect a jamming attack is not feasible for real-time applications. Hence, we propose methods to detect jamming attacks in real-time. Our methods allow real-time detection with high accuracy, not only at the central monitor but also at each vehicle. Therefore, vehicles are noticed about the attack soon enough to recover the communication and react to these attacks
