Abstract:
Two methods for assessing the road damaging potential of heavy vehicles are described in this paper. The methods use a simple laboratory test to characterize vehicle dynamics. This information is then used to predict the dynamic tyre forces generated by the vehicle for typical highway conditions. A quarter car laboratory test rig fitted with a leaf spring suspension is used to investigate these methods. Step inputs are used to excite the rig, and various sensors measure the response. A linear technique using the convolution algorithm is investigated initially. A non-linear method using parameter estimation is then examined. The accuracy of both systems is determined by comparing tyre force data measured on the test rig with predicted tyre forces.

Abstract:
Off-Road Environment Simulator (ORES) is a Real-time Hardware-in-the-Loop (RT-HIL) platform to simulate the dynamic response of off-road vehicles. This paper primarily focuses on the vehicle model development and validation using both field and rig testing using the ORES platform. Off-road vehicles are capable of operating on bumpy terrains where they are subjected to different resistive wheel torques due to non-unique ground friction conditions and wheel loads. If the powertrain torque output is not distributed in accordance with the resistive wheel torques, it may lead to transmission windup resulting in premature failure of various driveline components. In this study, the vehicle is driven over discrete bumps both in rig simulation and field trial. Different terrain enveloping models were evaluated namely the single point, radial-spring contact model and two-point follower (using circular and sinusoidal basis). These models were evaluated against the measured wheel acceleration responses. The two-point follower with sinusoidal basis strongly correlates with the measured responses and the ground excitations so obtained were used as inputs to a seven degree-of-freedom vehicle ride model. Ride model calculates the wheel loads and is eventually integrated with longitudinal dynamics, tire, driveline and test-rig models. Vehicle axle acceleration, wheel speed and drive torque responses are measured for validating the simulation results against field and rig trials. The field responses matches fairly well which validates the suitability of the proposed modeling approach.

Abstract:
Air pollution and road traffic noise are two important environmental nuisances that could be harmful to the health and well-being of urban populations. In Mexico City, as in many North American cities, there has been an upsurge in bicycle ridership. However, Mexico City is also well known for having high levels of noise and air pollution. The purpose of this study is threefold: 1) evaluate cyclists’ exposure to air pollution (nitrogen dioxide) and road traffic noise; 2) identify local factors that increase or reduce cyclists’ exposure, in paying particular attention to the type of road and bicycle path or lane used; and 3) evaluate the influence of real-time traffic density on cyclists’ exposure. A total of 19 bicycle trips made in central Mexico City neighbourhoods were analyzed, representing nearly 11 hours and 137 km. The results of the Bayesian models show that type of road and bicycle infrastructure taken by the cyclist, and proximity to a main artery all have significant impacts on exposure levels. Finally, the variables introduced to control for the traffic encountered by cyclists had a significant positive effect on noise exposure, and a positive but not significant effect on nitrogen dioxide exposure.

Abstract:
Abstract Phenomena occurring at the interface between the tread compound and the road surface are responsible for at least two main tire characteristics: traction capability and wear resistance. Both depend on the road surface geometry, the presence of thin films of water, local contact pressure, tread element stiffness, temperature, tangential slip, etc. To discount the effect of tire construction, a laboratory test using a small solid rubber wheel has been considered. A rig is designed to easily change the “road” surface, and convert it from wet to dry conditions, run the rubber wheel on such surfaces under high braking or driving torque, and measure torque against longitudinal slip. The rig features a flat disk on which different surfaces can be simulated and two separate electric motors driving the disk and the test wheel in order to control slip instead of torque and to avoid instability at high driving or braking torques. Results show longitudinal characteristics versus slip in different test conditions and simulation of severe abrasion conditions leading to typical abrasion patterns.

Abstract:
A new vehicle active suspension with Electro-Hydrostatic Actuator (EHA) is suggested. The system consists of two parts: spring and actuator with variable control force. The actuator includes hydraulic cylinder, hydraulic pump, controller, etc. According to bond graph principle, bond graph model of EHA active suspension are built. For vehicle active suspension system, unavoidable time delay may appear in the controllable course. Time-delay influence on the dynamic performance of vehicle active suspension is analyzed. Physical prototype and experimental rig for EHA active suspension is built. Then the tests of suspension prototype with time-delay control are carried out on the developed test rig. The results show that the sprung mass acceleration of the active suspension with time-delay compensation significantly declines by 11.56% under the road input of 1.1Hz and by 12.8% under the road input of 1.5Hz

Anti-lock Braking System (ABS) has widespread used depending on its mature technology and superior performance. We design a test rig which can simulate the running condition of wheels for ABS to detect the braking performance. The kinetic energy of vehicle is replaced by the kinetic energy of rotating flywheel, and the tire-road friction coefficient is replaced by magnetic powder clutch. The amplitude of exciting current to the clutch has linear relationship with the friction coefficient, so as to provide a datum for detecting the working status of ABS under various road conditions. The system can realize simulating test of single road surface, bisectional road surface and joint road surface. The validity of the road simulation method can be verified by the real-time data from the user interface.

Abstract:
Warehouse forklifts are often powered by batteries. By using a test bench where the forklift can be driven in a certain driving-cycle, the battery capacity can be tested. To obtain the same speed curve on the test bench as a forklift obtains when driving on a real road, the test bench must be able to simulate road load. In this master’s thesis, a test bench is modelled in Simulink using grey-box modelling and validated with measured data. Also, a speed regulator is developed and implemented in the test bench model to simulate road load. Simulations with the model and the speed regulator show high accuracy when compared against measured data. However, the results show that the pre-attached torque sensor is not optimally located, and that the gear oil temperature is of interest to measure to be able to model the friction torque as a function of the temperature.
Lagertruckar drivs ofta av batterier. Batterikapaciteten kan testas genom att använda en testbänk där trucken körs i en körcykel. För att simulera samma hastighetskurva på testbänken som trucken erhåller vid riktig körning på väg måste testbänken kunna simulera vägmotstånd. I detta examensarbete modelleras en testbänk i Simulink genom grey-box modellering och valideras med uppmätt data. Även en hastighetsregulator utvecklas och implementeras i modellen för att simulera vägmotstånd. Simuleringar med modellen och hastighetsregulatorn visar på hög träffsäkerhet jämfört med uppmätt data. Resultaten visar dock på att den monterade momentsensorn inte är optimalt belägen och att växeloljans temperatur är av intresse att mäta för att kunna modellera friktionen som en funktion av temperaturen.

Mestrado em Engenharia Mecânica
Os veículos autónomos são uma tendência cada vez mais crescente nos dias de hoje com os grandes fabricantes da área automóvel, e não só, concentrados em desenvolver carros autónomos. As duas maiores vantagens que se destacam para os carros autónomos são maior conforto para o condutor e maior segurança, onde este trabalho se foca. São incontáveis as vezes que um condutor, por distração ou por outra razão, não vê um objeto na estrada e colide ou um peão na estrada que e atropelado. Esta e uma das questões que um sistema de apoio a condução (ADAS) ou um carro autónomo tenta solucionar e por ser uma questão tão relevante há cada vez mais investigação nesta área. Um dos sistemas mais usados para este tipo de aplicação são câmaras digitais, que fornecem informação muito completa sobre o meio circundante, para além de sistemas como sensores LIDAR, entre outros. Uma tendência que deriva desta e o uso de sistemas stereo, sistemas com duas câmaras, e neste contexto coloca-se uma pergunta a qual este trabalho tenta respoder: "qual e a distância ideal entre as câmaras num sistema stereo para deteção de objetos ou peões?". Esta tese apresenta todo o desenvolvimento de um sistema de visão stereo: desde o desenvolvimento de todo o software necessário para calcular a que distância estão peões e objetos usando duas câmaras até ao desenvolvimento de um sistema de xação das câmaras que permita o estudo da qualidade da deteção de peões para várias baselines. Foram realizadas experiências para estudar a influênci da baseline e da distância focal da lente que consistriam em gravar imagens com um peão em deslocamento a distâncias pré defenidas e marcadas no chão assim como um objeto xo, tudo em cenário exterior. A análise dos resultados foi feita comparando o valor calculado automáticamente pela aplicação com o valor medido. Conclui-se que com este sistema e com esta aplicação e possível detetar peões com exatidão razoável. No entanto, os melhores resultados foram obtidos para a baseline de 0.3m e para uma lente de 8mm.
Nowadays, autonomous vehicles are an increasing trend as the major players of this sector, and not only, are focused in developing autonomous cars. The two main advantages of autonomous cars are the higher convenience for the passengers and more safety for the passengers and for the people around, which is what this thesis focus on. Sometimes, due to distraction or another reasons, the driver does not see an object on the road and crash or a pedestrian in the cross walk and the person is run over. This is one of the questions that an ADAS or an autonomous car tries to solve and due to the huge relevance of this more research have been done in this area. One of the most applied systems for ADAS are digital cameras, that provide complex information about the surrounding environment, in addition to LIDAR sensor and others. Following this trend, the use of stereo vision systems is increasing - systems with two cameras, and in this context a question comes up: "what is the ideal distance between the cameras in a stereo system for object and pedestrian detection?". This thesis shows all the development of a stereo vision system: from the development of the necessary software for calculating the objects and pedestrians distance form the setup using two cameras, to the design of a xing system for the cameras that allows the study of stereo for di erent baselines. In order to study the in uence of the baseline and the focal distance a pedestrian, walking through previously marked positions, and a xed object, were recorded, in an exterior scenario. The results were analyzed by comparing the automatically calculated distance, using the application, with the real value measured. It was concluded, in the end, that the distance of pedestrians and objects can be calculated, with minimal error, using the software developed and the xing support system. However, the best results were achieved for the 0.3m baseline and for the 8mm lens.

Abstract:
This master thesis project aims to complete and verify core functions of a test rig that is designed and built to emulate drive cycles for measuring the energy consumption of HEVs, especially a vehicle named ELBA from KTH Integrated Transport Research Lab (ITRL). To fulfill this goal, a simplified model is created for the test rig, whose involved parameters are identified through various experiments. Then the model is verified by both step voltage responses and sinusoidal current responses. Meanwhile, vehicle dynamics is modeled to calculate required resistance force for road slope emulation. Moreover, an existing method, vehicle equivalent mass, is utilized to compensate dynamic force of the vehicle body, enabling simulation of regenerative braking without an extra flywheel. Together with test rig’s model that is responsible for converting required resistance force to demanded current reference, the rig’s functions are completed and ready for final verification. As a result, the driver of the DC motor on the rig is found to has lower current limitation than required so that the rig is not able to entirely compensate dynamic force of the car. However, the feasibility of the principle is still proved by the tests. Based on the result, recommendations are given to solve the problem and achieve other improvements in the future.
Detta examensarbete syftar till att slutföra och verifiera kärnfunktioner i en testrigg som är designad och byggd för att emulera körcykler för att mäta energiförbrukningen för elhybridbilar, särskilt ett fordon som heter ELBA från KTH Integrated Transport Research Lab (ITRL). För att uppfylla detta mål skapades en förenklad modell för testriggen, vars parametrar identifieras genom olika experiment. Sedan verifieras modellen av både stegspänningssvar och sinusformade strömsvar. Under tiden modelleras fordonsdynamiken för att beräkna erforderlig motståndskraft för väglöpemulering. Samtidigt modelleras fordonsdynamiken för att beräkna den erforderliga motståndskraften för emulering av väglutningar. Dessutom används en befintlig metod, fordonsekvivalentmassa, för att kompensera fordonskroppens dynamiska kraft, vilket möjliggör simulering av regenerativ bromsning utan extra svänghjul. Tillsammans med testriggens modell som är ansvarig för att konvertera erforderlig motståndskraft till efterfrågad strömreferens, är riggens funktioner färdig och redo för slutlig verifiering. Som ett resultat har föraren av likström motorn på riggen visat sig ha lägre strömbegränsning än vad som krävs så att riggen inte helt kan kompensera bilens dynamiska kraft. Emellertid bevisas principens genomförbarhet fortfarande av testerna. Baserat på resultatet ges rekommendationer för att lösa problemet och uppnå andra förbättringar i framtiden.

Abstract:
This research activity is focused on the development of new experimental methodologies for Non-Manual Transmissions, in particular for the calibration of the software that runs inside the Transmission Control Unit (TCU). Calibration is still an activity performed on vehicle but, due to several reasons, it is always more necessary to move it from Road to Rig: this concept allows to move a part of the development process of a new vehicle from the road to the test benches. Perform calibration on the road means to work directly on prototypes vehicles, that have high costs, and to be subject to external conditions that make the maneuvers not repeatable. On the other hand, work on bench assure, for sure, repeatability, so no influences of external conditions; a single test bench is able to simulate different types of vehicle, with a significant cost reduction. This research activity was scheduled in two main parts. The first, that concerns the development of the test bench used during the whole activity, a Transmission Test Bench in which the gearbox is physically present and all the other elements, such as engine and vehicle, are simulated: configuration, building of simulation models, calibration of these models, creation of test patterns. The second, that concerns the development of new experimental calibration methodologies: using the repeatability of the test bench, it was possible to reproduce many maneuvers on the bench and it was possible to improve the management of this maneuver, and then test the new solutions on vehicle, with good results. Moreover, the punctual characterization of certain components is possible, due to the precision and reliability of the test bench: in particular, the activity is focused on thermal behavior of gearbox and clutches, clutches friction coefficient function of temperature, clutches dynamic response. The self-developed experimental methodologies were built both off-line than on-line (real time) with the simulation models of the bench; with the test patterns built in the first phase of the research activity, it was possible to create automated calibrations tools that allow to actuate autonomously the system, read the output, optimize the result via self-developed estimation algorithm, and actuate again the system with the new calculated value, in order to find the best compromise for certain physical aspects. Due to the confidentiality of the contents, all the graphs represented in this work have no indications of units and values.

Full text
Abstract:
Road vehicle tyres, railway wheels and ball bearings all generate rolling contact forces which are transferred within a finite area of contact between the rolling element and the substrate. Either it is visible or not for the human eye, a certain degree of roughness is always present on the contacting surfaces and it influences the generation of both vertical and lateral contactforces. The purpose of this investigation is to enhance the understanding and modelling of the influence from small-scale surface roughness on the generation of rolling contact forces. To this end, a computationally efficient method to include roughness-induced contact nonlinearities in the dynamic modelling of rolling contacts is proposed. The method is implemented in a time domain model for vertical wheel–track interaction to model rolling-induced rail vibrations, showing good agreement with measurements. Furthermore, a test rig is developed and used for the investigation of tyre–road rolling contact forces. Detailed studies are performed on the influence of substrate roughness on the resulting contact forces for a tyre tread block which is rolling at different operating conditions. The choice of substrate as well as the rolling velocity and the slip ratio is observed to have significant influence on the resulting friction coefficient. For high slip ratios, stick–slip oscillations appear, exhibiting frequency content which is largely dependent on the choice of substrate. The outcomes of this study can potentially be used to improve future tyre–road contacts with respect to wear, traction and noise generation.

Full text
Abstract:
Les modèles de contact dynamique pour le bruit de roulement reposent souvent sur une hypothèse quasistatique et une approximation de massif semi-infini pour le pneu. L’objectif de la thèse est de vérifier ces hypothèses par la mesure de forces de contact sur un banc d’essai constitué d’un pneu lisse de taille réduite roulant sur un bâti cylindrique. Au préalable, l’analyse modale expérimentale du pneu permet d’identifier des modes propres de formes classiques. Bien qu’un modèle éléments finis basé sur une section de pneu homogène élastique donne des modes satisfaisants, une section hétérogène hyper-viscoélastique permet d’obtenir un bon compromis entre vibrations et contact statique. La force de contact dynamique lors du roulement du pneu sur une seule aspérité sphérique ou conique est ensuite mesurée. La relation entre la force maximale et la hauteur de l’aspérité est conforme aux lois de contact théoriques. La durée de contact sur l’aspérité est inversement proportionnelle à la vitesse. Les calculs de contact basés sur un massif semi-infini élastique permettent d’approcher correctement la force maximale mesurée pour les fortes hauteurs d’aspérités, mais pas pour les faibles. La dissymétrie du signal temporel de force est bien modélisée en introduisant la viscoélasticité dans le modèle. Les forces de contact dynamique mesurées entre le pneu et plusieurs aspérités de formes simples confirment les résultats précédents, démontrant dans l’ensemble la nature quasi-statique du contact roulant. Toutefois, les forces calculées sont sous-estimées sur les bords de l’aire de contact, montrant une limitation de l’hypothèse de massif semi-infini pour décrire la structure du pneu
The dynamic contact models for tyre/road noise are often based on a quasi-static assumption and a half-space approximation for the tyre. The aim of the thesis is to assess these assumptions by measuring contact forces on a test rig composed of a smooth reduced-sized tyre rolling on a cylindrical basis. Beforehand, the experimental modal analysis of the tyre allows the identification of eigenmodes of classical shapes. Although a finite element model based on a homogeneous elastic tyre section yields satisfactory modes, a hyper-viscoelastic heterogeneous section provides a good compromise between vibrations and static contact. The dynamic contact force on a single spherical or conical asperity during rolling of the tyre is then measured. The relationship between the maximum force and the height of the asperity is consistent with theoretical contact laws. The contact duration on the asperity is inversely proportional to the speed. The contact calculations based on an elastic half-space assumption lead to a proper estimation of the maximum force measured on high asperity heights, but not on low asperity heights. The dissymmetry of the force time signal is well modelled by introducing the viscoelasticity in the model. The dynamic contact forces measured between the tyre and several asperities of simple shapes confirm the previous results, demonstrating the quasistatic nature of the rolling contact. However, the calculated forces are underestimated at the edges of the contact area, showing a limitation of the half-space assumption to describe the tyre structure

Abstract:
Rio de Janeiro, Brazil is currently in the midst of extraordinary period of mega-event hosting. Central to the preparation and hosting of such mega-events are the issues of infrastructure and image. While a large number of articles have been keen to illustrate the transformative potential (and dilemmas) of utilizing mega-events to advance an urban agenda, less understood is role that citizen journalists and traditional media journalists play in the construction of the "media geography" of mega-events. This research examines the dominant narratives in the international media coverage of Rio de Janeiro, Brazil before the 2014 FIFA World Cup, specifically the 12 months leading up to that event starting with the 2013 Confederations Cup Riots. Data was derived from a content analysis of 5 western, international media outlets, as well as interviews with international and new media journalists from the New York Times, BBC, Wall Street Journal, Associated Press, Midia NINJA, and several other media organizations. These journalists were questioned about the dominant media narratives, as well as the role of new media, not only in reporting news on the ground in Rio de Janeiro, but also in how their presence helped shape the media's representation of Rio and perhaps construct a new "point of reference" for the city. The results of the quantitative and qualitative data suggest a couple of clear narratives. The first questioned whether or not the event's infrastructure projects would be ready in time for the start of the games. The second focused on reporting of the protests in Rio de Janeiro and elsewhere, attempting to give meaning to protests and the array of grievances that sparked those demonstrations. Additionally, this research examined how traditional and new media journalists leveraged social media to mobilize and facilitate the various contestations of Rio de Janeiro's mega-events.

Correctly identifying the road area on an image is a crucial task for many traffic analyses based on surveillance cameras and computer vision. Despite that, most of the systems do not provide this functionality in an automatic fashion; instead, the road area needs to be annotated by tedious and inefficient manual processes. This situation results in further inconveniences when one deals with a lot of cameras, demanding considerable effort to setup the system. Besides, since traffic analysis is an outdoor activity, cameras are exposed to disturbances due to natural events (e.g., wind, rain and bird strikes), which may require recurrent system reconfiguration. Although there are some solutions intended to provide automatic road detection, they are not capable of dealing with common situations in urban context, such as poorly-structured roads or occlusions due to objects stopped in the scene. Moreover in many cases they are restricted to straight-shaped roads (commonly freeways or highways), so that automatic road detection cannot be provided in most of the traffic scenarios. In order to cope with this problem, we propose a new approach for road detection. Our method is based on a set of innovative solutions, each of them intended to address specific problems related to the detection task. In this sense, a context-aware background modeling method has been developed, which extracts contextual information from the scene in order to produce background models more robust to occlusions. From this point, segmentation is performed to extract the shape of each object in the image; this is accomplished by means of a superpixel method specially designed for road segmentation, which allows for detection of roads with any shape. For each extracted segment we then compute a set of features, the goal of which is supporting a decision tree-based classifier in the task of assigning the objects as being road or non-road. The formulation of our method — a road detection carried out by a combination of multiple features — makes it able to deal with situations where the road is not easily distinguishable from other objects in the image, as when the road is poorly-structured. A thorough evaluation has indicated promising results in favour of this method. Quantitatively, the results point to 75% of accuracy, 90% of precision and 82% of recall over challenging traffic videos caught in non-controlled conditions. Qualitatively, resulting images demonstrate the potential of the method to perform road detection in different situations, in many cases obtaining quasi-perfect results.

Abstract:
AbstractProperty development, especially landed houses, is taking place around the Surabaya Outer West Ring Road (JLLB) infrastructure plan. These days, there are dozens of new residential areas in the border area of Western Surabaya and Southern Gresik, East Java Province, Indonesia, utilizing JLLB’s plans and physical progress. Property marketing activities around JLLB Surabaya cannot be separated from the entrepreneurial orientation and entrepreneurial marketing of property developers in Greater Surabaya. Taking the momentum of property business opportunities, measurable business risks, long time-held land resources around JLLB, and offering future value property investment for consumers are entrepreneurial marketing and entrepreneurial orientation practices that property developers have successfully carried out on the border of Western Surabaya and Southern Gresik.

Abstract:
Ride has always been an important aspect in vehicle design, driven by the customer’s increasing demand for vehicles with better comfort. The vibrational response of the vehicle is one of many factors contributing to the overall ride perception, with road inputs being the major excitation source. The improved capabilities of vehicle simulation models and virtual proving grounds have supplemented experimental prototype testing for tuning suspensions. Final tuning, and ride evaluation, is however still done through physical on-road testing. Four-post rig tests hold potential cost and time savings when used appropriately in the development process. The four-post rig imposes only vertical inputs at the tire contact patches and thus it is expected for the vertical response of the vehicle to be the dominant component. The objective of this paper is to determine whether ride comfort can sufficiently be evaluated on the four-post rig using only the vertical seat Component Ride Value (CRV). The response of an instrumented vehicle on the four-post rig was measured by a tri-axial seat pad accelerometer. Vertical, longitudinal and lateral seat CRVs as well as the seat Point Ride Value (PRV) were calculated from the measured seat acceleration in the three translational directions using the BS6841 (1987) standard. The PRV is the square root of the sums of squares of the three CRVs. The CRVs and PRV, obtained from tests at various speeds and road roughnesses, were analyzed to determine whether the vertical seat CRV is sufficient in capturing the perceived ride comfort. Results showed that the longitudinal and lateral CRVs are in excess of 26% and 63%, respectively of the dominant vertical seat CRV over the various tests. This implies that the vertical seat CRV underestimated the discomfort when compared to the seat PRV. It was also observed that the three CRVs had different sensitivities to test parameters and conditions. For example, at different speeds over the same road roughness the longitudinal CRV increased significantly more than the other two components. The differences in sensitivities may be due to the specific boundary conditions imposed on the vehicle by the four-post rig. It is concluded that the vertical seat CRV may not be sufficient to evaluate the ride comfort on a four-post rig.

Abstract:
Steel pipe pile as one of the foundation forms has the advantage of high bearing capacity, environment protection and installation, which were widely adopted to sea-crossing bridge, offshore wind power and marine oil rig at present. With the development of project scale, the length and diameter of the piles were increasing gradually. Meanwhile, civil engineers had to face the outstanding challenges in the production and transportation of extra-long and extra-large steel pipe piles. The design parameters of steel piles were controlled under the highest and strictest execution class EXC4 B+ in accordance with the European standard EN 1090-2. Additionally, the pile length of 130,6 m set a record for entire pre-fabricated longest steel pile in the field of civil engineering worldwide at that time. All the manufactured piles were delivered by cargo vessel after long voyage to Croatia. The accumulated experience of Pelješac Bridge could be as a reference for similar projects in future.

Full text
Abstract:
Introduction: Intraarticular fractures of the tibial plateau and periarticular fractures of the proximal tibia, caused by high energy trauma pose a therapeutic dilemma. Such fractures are associated with extensive soft tissue damage with or without compound injury. The management of such high velocity injuries become a challenge to the trauma surgeons. The goals of these periarticular fractures management are 1. Restoration of joint congruity by anatomic reduction 2. Stable xation of fractures thus allowing early movements 3. Proper care of injured soft tissues. In earlier days uniplanar external xation were used with various complications like pin track infections and decreased stability. In this study we present the use of hybrid external xation system which includes Ilizarov ring xator and AO rod external xator connected with indigenously manufactured connecting clamps and short shafts augmented with or without minimal internal xation. The purpose of this study is to assess the utility of this hybrid external xation system and to analyse the functional outcome, soft tissue healing and fracture union. To assess the performance of the Hybrid External Fixator Aim and Objective: in the treatment of different types of proximal tibial fractures, to evaluate the functional outcome, soft tissue healing and fracture union and radiological outcome, to evaluate the biomechanical and biological advantage of hybrid external xator, to assess the utility of the indigenously made connecting clamps. Material and Method: The study included 21 cases of periarticular fractures of the proximal tibia which were treated by use of 5/8th Ilizarov ring, AO tubular external xator and with indigenously manufactured connecting clamps & short shaft in a hybrid mode. All cases were prospectively followed up and studied. Almost all the cases (99%) had sustained Road trafc Accidents (high velocity injuries) except one case which had sustained injury by fall of cement wall over her leg. Minimum follow up – 1.5 months, maximum follow up – 12 months, mean follow up – 6.42 months. All fractures were followed according to a protocol. All fractures were treated with either CLOSED REDUCTION AND HYBRID EXTERNAL FIXATION OR WITH MINIMAL OPEN REDUCTION AND A HYBRID SYSTEM. The study group was consisted of 16 males (76%) and 5 females (24%) with an average age for males of 43.06 years (range 25 to 65) and for females of 53.4 years (range 41 to 59). All the patients were in the age group of 26 to 65 years, mean age is 43.09. In the present s Result: tudy of 21 cases, the use of Hybrid external xation, as a denite treatment, for high – energy proximal tibia bicondylar fractures proved to be benecial.

Abstract:
Increased urbanization, population growth, and demand for time-sensitive deliveries means increased freight movement in cities, which contributes to emissions, noise, and safety concerns. One innovative mode gaining widespread attention for urban deliveries is cargo cycles—bicycles adapted for freight delivery. Despite the recognized potential and possible success of transporting at least 25% of freight via cycle, research remains limited. This research investigates the potential of cargo cycle delivery for last mile freight in Oakland, California, with a focus on the West Oakland neighborhood. The data collection included interviews, focus groups, vehicle field observation and counts, and traffic simulation modeling. The traffic simulation examined scenarios where businesses converted different percentages of current deliveries to cargo cycles using a transfer hub as the starting point for their cargo cycle delivery. The best-case scenario—where the maximum percentage of deliveries were made with cargo cycle instead of motorized vehicles—resulted in reductions of 2600 vehicle miles traveled (VMT) per day. In that case scenario, the vehicle miles traveled (VMT) reduction is equivalent to a reduction in emissions of PM2.5, PM10, NOx, and reactive organic gas (ROG) of taking about 1000 Class 4 box trucks off the roads of West Oakland per day. In the worst-case scenario, with a significantly smaller percentage of motorized package deliveries converted to cargo cycles, there is a reduction of 160 VMT, equivalent to the removal of approximately 80 Class 4 box trucks off the roads of West Oakland per day. This potential reduction in air pollution and traffic congestion, as well as job creation, would benefit West Oakland residents.
