Public transportation is a critical component of urban communities and plays an important role in facilitating mobility which is integral to economic development and the quality of life of urban residents. In recent years, urban transportation has evolved rapidly with the emergence of transportation network companies (TNCs) and e-commerce that drastically transformed urban living. The availability of TNCs has given consumers more transportation options. However, the implications of TNCs on public transit ridership are unknown. In addition, the rising online shopping trend has drastically reduced the businesses of brick-and-mortar retailers, but does the shift in consumer shopping behavior reduce the demand for public transit? The objective of this dissertation is to address the following three research questions: (1) How is U.S. public transit ridership impacted by the rise of TNCs? (2) How have transit subcontracting (or purchased transportation) and TNC partnership affected transit productivity in recent years? (3) Has increased online shopping reduced the demand for public transit service? The key findings of my study are: (1) transit effectiveness of both bus and rail transits declined over the study period; (2) TNC availability increased rail transit ridership in 2015; (3) transit effectiveness was highly significant for public transit, and when examining its effect year-by-year, rail transit effectiveness trumped TNC availability; (4) TNCs are neither a complement nor a substitute of bus transit; (5) for bus transit agencies, outsourcing or purchased transportation is associated with negative efficiency and productivity changes; (6) although purchased transportation has a positive effect on technological change for bus transit, the effect is not significant; (7) TNC partnerships also have a negative effect on efficiency and productivity changes in bus transit; (8) there is a positive significant relationship between shopping mall visits and public transit use; (9) however, the effect of mall visits on transit use is small relative to the effects of car ownership; (10) taken together, the marginal effect of car ownership is 9 times larger than the effect of mall visits on transit use.

Transportation in densely populated areas is becoming increasingly problematic. Congestion, air pollution, accident-related fatalities and time wasted in traffic are only a few of issues associated urban transportation. Personal transportation is expected to increase by 63% total, where car traffic is expected to increase by 67% and railway traffic – by 80% during the period from 2006 to 2050. With that kind of dynamic, reaching the currently set sustainability goals is impossible. This raises the need for introducing sustainable public transportation solutions. Defining sustainability in the context of public transportation and taking into account the case-specific differences that affect the definition is an important step in this process. Quantification and the use of calculation tools for sustainability impact assessment are important for discussing the subject in concretized terms. Public transportation involves a multitude of stakeholders that each have their own responsibility areas. Since public transportation systems are ultimately a collective effort, every stakeholder has to partake in this endeavor on their corresponding level of responsibility. Socioeconomic criteria are an integral part of sustainability impact analysis, since it puts technical transport-related calculations into a broader context that goes beyond the transport sector. This is a qualitative applied study of Scania’s efforts in developing calculation models to facilitate leading the dialogue by providing quantitative evidence during the early stages of their solution sales process. In this report, the methodology for sustainability impact assessment, traffic planning and socioeconomic calculations are studied and applied on the case of Scania, where a holistic calculation tool is developed for the company. Bus Rapid Transit systems have been proven to be effective, sustainable solutions of public transportation in several regions. The vehicle fleet is an important component within the BRT system, which is why calculation tools for analysis of sustainability impacts of BRT systems have high strategic significance for Scania. By providing quantitative evidence of the benefits of sustainable public transportation, the company is going to be able to gain additional market shares while simultaneously promoting sustainable urban public transportation.
Transport i tätbefolkade områden blir alltmer problematiskt. Trängsel, luftföroreningar, olycksrelaterade dödsfall och tid bortslösad i trafiken är bara några av de typiska problemen som medföljer modern stadstrafik. Personlig transporter förväntas öka med 63% totalt, där biltrafiken förväntas öka med 67% och järnvägstrafiken - med 80% under perioden från 2006 till 2050. Om den typen av dynamik fortsätter, är det omöjligt att nå de i dagsläget satta hållbarhetsmålen. Detta skapar ett behov av att införa hållbara kollektivtrafiklösningar. Att definiera hållbarhet inom kollektivtrafiksammanhanget med hänsyn till fallspecifika aspekter som påverkar definitionen är ett viktigt steg i denna process. Kvantifiering och användning av beräkningsverktyg för att göra hållbarhetsbedömningar är viktiga för att diskutera ämnet i konkretiserade termer. Transportsektorn involverar en mängd aktörer som var och en har sina egna ansvarsområden. Eftersom kollektivtrafiksystem i slutändan definieras av samtliga aktörernas kollektiva insats, är det upp till varje aktör att engagera sig i processen på deras motsvarande ansvarsnivå. Samhällsekonomiska kriterier är en viktig del av hållbarhetskonsekvensbeskrivning, eftersom det sätter tekniska transportrelaterade beräkningar i ett bredare sammanhang som sträcker sig utöver transportsektorn. Detta är en kvalitativ tillämpad studie av Scanias arbete inom utveckling av beräkningsmodeller som ska underlätta att föra dialogen genom att tillhandahålla kvantitativa bevis i ett tidigt skede i försäljningsprocessen av kollektivtrafiklösningar. I denna rapport, är metodiken för hållbarhetskonsekvensbeskrivning, trafikplanering och samhällskonomiska beräkningar studerad och tillämpad på fallet Scania, där ett helhetsberäkningsverktyg har utvecklats för företaget. Bus Rapid Transit-system har visat sig vara effektiva och hållbara lösningar för kollektivtrafiken i flera regioner. Fordonsparken är en viktig komponent i BRT-systemet, vilket är anledningen till att beräkningsverktyg för analys av hållbarhetseffekterna av BRT-system har hög strategisk betydelse för Scania. Genom att uttrycka fördelarna med hållbar kollektivtrafik i kvantifierade termer kommer företaget att kunna få ytterligare marknadsandelar och samtidigt främja hållbar storstadskollektivtrafik.

The primary objective of this study is to develop an integrated public transportation planning framework to evaluate and plan Advanced Public Transportation Systems (APTS). With this purpose, a systems approach point of view is adopted to study the influence of new APTS technology in supply and demand transit variables. In this project the Systems Dynamics methodology is adopted to track the dynamic behavior of model variables and feedback loops forming among them. The proposed framework is illustrated in a case study involving automated vehicle location systems (AVL) applied to a small transit community. The proposed approach follows the same steps of the Systems Dynamics method; First, identify some key variables which are not only susceptive to AVL technology but also affect the supply-demand relationship of a bus transit environment. Second, trace and simplify the causal relationships of the variables considering impacts of facility supply changes to passenger demand responses and vice versa. To accomplish this, four detailed sub-models representing parts of the transit system are developed and combined under the Systems Dynamics methodology point of view. Theses Sub-models are: 1) demography, 2) urban transportation planning, 3) bus operations, and 4) evaluation. Finally, to validate the model procedure, the model is applied to a case study. This study attempts to encompass as many as possible factors around a bus transit system environment which can be impacted by new APTS technology to illustrate the use of the proposed framework. Some of these factors include: 1) Demographic characteristics; 2) urban or social activity of the study area and 3) changes to transportation facilities. The case study illustrates how the physical characteristics of the transit systems such as traffic demand, traffic conditions along the transit route, route layout, and bus performance can be affected by the new technology. Since APTS impacts are time dependent a continuous multi-loop simulation technique is adopted to track dynamic changes of all model variables. The analysis of the transit system is carried over a 20-year life cycle to illustrate the long term dynamics of the feedback structures inherent in the model. [Vita removed Aug. 2, 2010. GMc]

The autonomous vehicle (AV) is poised to be one of the most disruptive technologies in the transportation industry. The advent of three major trends in transportation: automation, on-demand mobility and ride-sharing, are set to revolutionize the way we travel. The forthcoming adoption and commercialization of AVs are expected to have extensive impacts on our road networks, congestion, safety, land use, public transportation (PT) and more. Rapid advances in AV technology are convincing many that AV services will play a significant role in future transportation systems. The advancement of AVs presents both opportunities and threats to transportation. It has the potential to significantly impact traffic congestion, traffic accidents, parking and VMT (vehicle miles traveled), especially for people that are not able to drive such as children and elderly people. Motivated by the potential of autonomous vehicles, authorities around the world are preparing for this revolution in transport and deems this an important research direction that requires significant investigation. This thesis tackled and contributed to three main research questions related to the impact of autonomous vehicles on transportation systems. First, this thesis proposes a simulation-based approach to the design and evaluation of integrated autonomous vehicle and public transportation systems. We highlight the transit-orientation by respecting the social-purpose considerations of transit agencies (such as maintaining service availability and ensuring equity) and identifying the synergistic opportunities between AV and PT. Specifically, we identified that AV has a strong potential to serve first-mile connections to the PT stations and provide efficient and affordable shared mobility in low-density suburban areas that are typically inefficient to serve by conventional fixed-route PT services. The design decisions reflect the interest of multiple stakeholders in the system. Second, the interaction between travelers (demand) and operators (supply) is modeled using a system of equations that is solved as a fixed-point problem through an iterative procedure. In this, we developed demand and supply as two sub-problems. The demand will be predicted using a nested logit model to estimate the volume for different modes based on modal attributes. The supply will use a simulation platform capable of incorporating critical operational decisions on factors including fleet sizes, vehicle capacities, sharing policies, fare schemes and hailing strategies such as in-advance and on-demand requests. Using feedback between demand and supply, we enable interactions between the decisions of the service operator and those of the travelers, in order to model the choices of both parties. Finally, this thesis systematically optimizes service design variables to determine the best outcome in accordance to AV+PT stakeholder goals. Optimization objective functions can be formulated to reflect the different objectives of different stakeholders. In this paper, we specifically propose and develop a simulation-based service design method where we quantify various benefits and costs to reflect the objectives of key AV+PT stakeholders. We simulate the service with different sets of system settings and identify the highest performing set. We employ a case study of regional service contracting to showcase the ability of this method to inform AV+PT service design. We tested our approach with a case study area in a major European city on an agent-based simulation platform, amod-abm. Agent-based simulation has the advantage of capturing individual (agent) behaviors and the interactions of the various individual agents in a realistic synthetic environment where the intent is to re-create a complex phenomenon of mobility on demand service delivered by AV. Although this thesis will focus on a major European city, the general framework and methodologies proposed here can be widely applicable. The thesis concludes that the demand-supply interaction can be effective for designing and assessing the role of AV technology in our mobility systems. Moreover, simulation-based optimization can be an effective method for transit agencies to make decisions that support their overall AV related transport strategy as well as operational planning.

This thesis describes the nature of the specification and design of revenue collection systems from four urban mass transit systems: Manchester Metrolink, Sheffield Suptertram, Grenoble Tag Light Rail system and the Netherlands National Ticketing system. Previous research in this area has been generated from an industry perspective that has focused on new technologies and types of ticketing systems available. In addition fare collection is frequently discussed, and there is academic research available, in relation to pricing theory and policy. However, as yet there appears to be no theoretical or empirical research examining urban mass transit revenue collection systems and their specification. This research was initiated from a supplier of revenue collection systems expressing dissatisfaction in the design and specification selection procedure. In addition there was a need to conceptualise the important role that a revenue collection system plays in achieving a public transport operator's objectives. The aim of this study was to add to the theoretical base of this research area through the four case studies and to improve the design and selection of revenue collection systems in `real life' situations. Due to the nature of the research area being `real world' and revenue collection systems being bespoke, theoretical propositions were created from the literature review in order to guide the research and test the hypothesis. Through the theoretical proposition the role of the revenue collection system in a service marketing context is also established. This thesis is presented in seven chapters. Chapter 1 provides an introduction and background information to the research area. In Chapter 2 the research methodology is discussed together with the nature of the research. In Chapter 3 the literature review and the generation of the theoretical propositions and hypothesis are presented. In Chapter 4 the case studies describe the nature of the revenue collection systems and their specifications. In chapter 5 the case study analysis is undertaken based upon the theoretical propositions. Chapter 6 presents the overall conclusions and tests the hypothesis; it also presents recommendations for improving revenue collection system specification. Finally Chapter 7 discusses the research and its strengths and weaknesses and suggests areas for further research.

Governments around the world are investing heavily in smart card infrastructure to enhance transport services. Studies show that smart card technology can improve reliability, reduce maintenance costs, provide a longer life span, and allow more applications to be incorporated in a transit card. As a result, policy makers and transport owners are interested in extending the use of smart cards from transit to non-transit systems to capitalise on their investment. However, little is known about the conditions under which customers would adopt transit cards for non-transit transactions. In Singapore, a contactless transit smart card (ez-link card) was launched in April 2002 to replace the magnetic stored-value card, which was commissioned in December 1990. The ez-link card was introduced as an integrated public transport card for use both on buses and Mass Rapid Transit (MRT) and Light Rail Transit (LRT) trains. This study was undertaken to evaluate customers' response to the use of the ez-link card for non-transit transactions. As the ez-link card is an information technology (IT) product and the first of its kind in the Singapore public transport system, there is a need to understand and appreciate how customers would respond to the change in its use. Various theories and models such as the Technology Acceptance Model (TAM), Theory of Diffusion (TD), Theory of Reasoned Action (TRA) and Theory of Planned Behavior (TPB) were reviewed for their potential to understand and predict customers' intentions to use the ez-link card for non-transit transactions. After much review, the TPB was adopted for identifying the research model and hypotheses in this study. The TPB was used to develop the research model and hypotheses comprising one dependent variable (intention INT) and three independent variables (attitude - ATT, subjective norm - SN and perceived behavioral control - PBC). The TPB was also used to design the questionnaire comprising 16 items to collect data from customers using the ez-link card at bus interchanges and train stations located around Singapore. A pilot survey was conducted on 21 respondents using the intercept interview technique. The data were collected and analysed. With slight modifications, the questionnaire was then used with 300 respondents in the final survey. Descriptive and inferential statistics were used to analyse the data collected from 293 respondents (seven were outliers) using the intercept interview technique in the final survey. Regression analysis explained 80% of the variance in the customers' intention to use the ez-link card for non-transit transactions. While the results provided initial support for the TPB, further examination of the data using exploratory factor analysis revealed high correlations between the ATT and SN. This study concluded that a more parsimonious model would only extract two independent variables (Desirability - DES and Perceived Convenience PEC) to predict customers' intention to use the ez-link card for non-transit transactions. DES and PEC were used to develop a new

Increasing population growth in urban areas has led to significant problems, stretching the limits of existing urban transportation systems. While once playing a critical role in transport in the early development of cities, water transport has since declined sharply in relevance with increases in bridges, tunnels and the widespread proliferation of automobiles. But land based mass transit systems are often reaching capacity. These issues have led to a resurgence of interest in the use of urban ferry services as transport corridors along currently underutilised waterways. Cities such as Brisbane, New York, London, Gothenburg and Bangkok have operating urban ferry systems which play an important role in the transport functions of each city. In order to provide a better understanding of the operation of water transport services, their wider impact and the implications for their inclusion in future city planning, this thesis investigates key issues for planning this form of transport.

As the transportation sector fully integrates information technology, transit agencies face decisions that expose them to new technologies, relationships and risks. Accompanying a rise in transit-related web and mobile applications, a set of competing real-time transit data standards from both public and private organizations have emerged. The purpose of this research is to understand the standard-setting processes for these data standards and the forces that move the transit industry towards the widespread adoption of a data standard. This project will analyze through case studies and interviews with members of standard-setting organizations the development of three real-time transit data standards: (1) the development of the General Transit Feed Specification Realtime (GTFS-realtime), (2) the Service Interface for Real Time Information (SIRI), and (3) Transit Communications Interface Profiles (TCIP). The expected outcome of this research is an assessment of federal policy on standards development as well as an analysis of current and future trends in this sector—both technical and institutional. The results will inform federal transit policy and future action in standards-setting and intelligent transportation systems (ITS) requirements, identifying the potential catalysts that will increase the effectiveness of federal- and agency-level programs.

Real-time information that informs transit riders about transit schedules, next bus or train arrivals, and service alerts, is becoming increasingly available, particularly through internet-enabled smartphone applications. However, the extent of communication technology usage amongst transit riders, specifically their access to mobile applications and alternative technologies that can provide real-time information, is largely unknown. Without this information, transit agencies are risking investing in an alternative technology that may not sufficiently supply real-time information to as many as possible riders. The purpose of this study is to identify the differences in individual technology accessibility and prioritize investing in real-time information application development that mirrors the unique characteristics of transit riders. This recognition and development will allow a wider availability of real-time information amongst transit riders. Paired with an investigation of cellular phone usage among transit riders and the general American population, an analysis of Saint Louis Metro’s Onboard Survey was performed. Cross tabulations and chi-squared tests were conducted to examine riders’ communication technology usage. Binary logit models were used to understand how, and whether, the ownership of smartphone applications is dependent on various demographic factors. These analyses identified specific demographic groups that would benefit from supplemental technology methods more conducive to their particular information accessibility. Results showed that communication technology usage has risen substantially in recent years but a portion of riders are still without access to smartphone applications. Specific demographic groups (e.g., riders over 40 years of age) were less likely to own smartphones, and these results indicate that computer-based websites and IVR are the best supplementary alternatives for those groups.

Urban areas are currently facing challenges in terms of traffic congestion due to city expansion and population increase. In some cases, physical solutions are limited. For example, in certain areas it is not possible to expand roads or build a new bridge. Therefore, making public transpiration (PT) affordable, more attractive and intelligent could be a potential solution for these challenges. Accuracy in bus running time and bus arrival time is a key component of making PT attractive to ridership. In this thesis, a dynamic model based on Kalman filter (KF) has been developed to predict bus running time and dwell time while taking into account real-time road incidents. The model uses historical data collected by Automatic Vehicle Location system (AVL) and Automatic Passenger Counters (APC) system. To predict the bus travel time, the model has two components of running time prediction (long and short distance prediction) and dwell time prediction. When the bus closes its doors before leaving a bus stop, the model predicts the travel time to all downstream bus stops. This is long distance prediction. The model will then update the prediction between the bus’s current position and the upcoming bus stop based on real-time data from AVL. This is short distance prediction. Also, the model predicts the dwell time at each coming bus stop. As a result, the model reduces the difference between the predicted arrival time and the actual arrival time and provides a better understanding for the transit network which allows lead to have a good traffic management.

Satisfactory public transportation (PT) should enable people to reach attractive destinations and desired activities fast, comfortably, safely, and affordably. When PT fails to do so it will have negative effects on the overall accessibility in a society. Evaluating a PT system essentially means measuring to what extent the demand from the users is met, and for such an analysis understanding the concept of accessibility is paramount. Whether an individual will experience a high or a low level of accessibility will likely depend on their personal capabilities, as well as on the surrounding environment. Barriers obstructing an individual from using PT could for example be of physical of phycological nature or come in the shape of public space management disproportionally favoring certain groups of society. Low accessibility can thus be linked to social exclusion, since when a person cannot reach important destinations, their chances to participate in society will be subdued. To measure the accessibility of a PT system, and how a PT system affects the overall accessibility of a destination, it is common practice to use indicators that can represent different categories of social exclusion. This approach was the basis for constructing the performance measurement tool called Bus Stop Ranking Algorithm (BSRA) which was created in the QGIS application Graphical Modeler. BSRA calculates the usefulness of bus stops by counting the number of vulnerable groups, the number of workplaces, and the total population within comfortable walking distance from bus stops, as well as comparing travel times by car and bicycle from residential areas to important locations. The tool was ordered by a private PT company which will use it to make decisions regarding e.g., creating new bus stops, or for relocating, removing, or redesigning existing bus stops or bus routes. The Swedish municipality Lidingö was used as the study area to demonstrate how to use BSRA and how to interpret its output. Using equal weights for all indicators, it was discovered that 9 bus stops in the southern part of Lidingö could be regarded as particularly useful compared to the other 207 bus stops in the municipality. Variables such as the space-temporal component, i.e., changes during the day were not used. Socio economic factors such as segregation were also not highlighted, since all indicators had the same effect on the total scores. Adjusting the weights for some indicators could expose underlying dynamics affecting the total scores for the bus stops and help the PT company make design changes where they will be needed the most.

When implementing an intelligent transportation system (ITS), stakeholders often overlook the importance of evaluating the system once it is in place. Determining the extent to which the objectives of an investment have been met is important to not only the agency involved, but also to other agencies, so that lessons are learned and mistakes are not repeated in future projects. An effective evaluation allows a transit provider to identify and address areas that could use improvement. Agencies implementing ITS investments often have different goals, needs, and concerns that they hope their project will address and consequently the development of a generic evaluation plan is difficult to develop. While it is recognized that the U.S. Department of Transportation has developed guidelines to aid agencies in evaluating such investments, this research is intended to complement these guidelines by assisting in the evaluation of a site specific ITS investment. It presents an evaluation framework and plan that provides a systematic method for assessing the potential impacts associated with the project by defining objectives, measures, analysis recommendations, and data requirements. The framework developed specifically addresses the ITS investment on the OmniLink local route deviation bus service in Prince William County, Virginia, but could be used as a basis for the evaluation of similar ITS investments. The OmniLink ITS investment includes an automatic vehicle location (AVL) system, mobile data terminals (MDTs), and computer-aided dispatch (CAD) technology.

With the fast improvement of technology, accompanied by changes in the lifestyle and the growth of cities, that made the Public Transport (PT) system more complex, delivery of integrated information on PT systems in an efficient and clear way are of the outmost importance but not always available. This study sought to understand the relation between travel information, PT use intentions and non-habitual travel (at night). The hypothesis is that PT use intentions are related to the perceived usefulness and the ease-of-use of the system, which are related to information quality and real-time information availability. The hypothesized relations are anchored theoretically in the Extended Technology Acceptance Model and validated empirically in two sources of data: (i) Copenhagen (Denmark), characterized by a highly integrated PT system with an advanced web-based information system; (ii) Recife and Natal (Brazil), characterized by a lower perceived Level Of Service (LOS) and non-integrated information sources. The data was collected through a tailor-made survey answered for 1,123 university students in Denmark and Brazil. Structural equation models were employed for explaining the use of PT as a function of the observed respondent characteristics and the latent constructs. The results show: (i) information quality is essential for explaining PT use; (ii) perceived information quality is directly and positively related to perceived LOS, convenience and familiarity with the PT system; (iii) the use of real-time information is positively related to information quality and familiarity, while it is negatively associated with perceived PT security; (iv) PT use at night is positively related to habitual PT use and information search
Com a rápida melhoria da tecnologia, acompanhada por mudanças no estilo de vida, e o crescimento das cidades, que tornou o transporte público (TP) muito mais complexo, entregar informação integrada do sistema de transporte de uma forma eficiente e clara é de extrema importância, mas nem sempre está disponível. Este estudo procurou entender a relação entre informações sobre viagens, intenções de uso de TP e viagens não habituais (à noite). A hipótese é que as intenções de uso de TP estão relacionadas com a percepção sobre a utilidade e a facilidade de uso do sistema, que estão relacionados com a qualidade da informação e a disponibilidade de informação em tempo real. As relações hipotéticas são ancoradas teoricamente na Extensão do Modelo de Aceitação Tecnológica e validado empiricamente através de duas fontes de dados: (i) Copenhague (Dinamarca), caracterizado por um sistema de transporte altamente integrado com um avançado sistema de informação baseado na web; (ii) Recife e Natal (Brasil), caracterizadas por um nível de percepção do nível de serviço como mais baixo e fontes de informação não integradas. Os dados foram recolhidos através de um questionário feito sob medida e respondido por 1.123 estudantes universitários na Dinamarca e no Brasil. Modelos de equações estruturais foram utilizados para explicar a utilização do TP em função das características observadas dos respondentes e os construtos latentes. Os resultados mostram: (i) a qualidade da informação é essencial para explicar o uso do TP; (ii) a percepção da qualidade da informação está direta e positivamente relacionada com a percepção do nível de serviço, conveniência e familiaridade com o sistema de TP; (iii) o uso da informação em tempo real está positivamente relacionado com a qualidade da informação e familiaridade, enquanto está associado negativamente com a percepção de segurança do TP; (iv) utilização do TP à noite está positivamente relacionada com a utilização habitual do TP e a busca de informações

Application that combines crowdsourcing and gamification elements should be usable by as many passengers as possible, considering all the different smartphones available on the market and people with disabilities. Thus, most popular platforms for cross-platform mobile application development should be compared in order to choose the appropriate one for this project. Finally, application prototype should be further tested to gather more feedback about design and concept for improvements and future studies. Such solution is not meant to replace current methods of information gathering, but instead should be one of the available tools.

Os objetivos deste trabalho são dois: avaliar a percepção da sociedade e dos especialistas em transporte sobre os benefícios alcançados com a implantação de sistemas de transporte público urbano sobre trilhos e verificar se a percepção dos especialistas é alinhada com a percepção da sociedade. O trabalho foi desenvolvido a partir de uma pesquisa bibliográfica para identificação dos benefícios do transporte público sobre trilhos. Após definidos os benefícios foi aplicada uma pesquisa, de caráter exploratório, utilizando a escala de Likert, à sociedade, mais especificamente a alunos de graduação de cursos universitários na região metropolitana de São Paulo num total de 433 respondentes, distribuídos em 7 locais distintos. Em seguida foi realizada uma pesquisa junto a especialistas em transporte, com utilização de uma planilha para avaliação dos benefícios com base no Método de Análise Hierárquica - MAH. Na pesquisa com especialistas obteve-se 34 planilhas distribuídas em 4 grupos distintos. Os resultados mostram que a sociedade e os especialistas possuem uma percepção bastante positiva dos benefícios gerados pela implantação de sistemas de transporte público urbano sobre trilhos, havendo, no entanto, diferenças sensíveis nas avaliações, que refletem na ordem de importância dos benefícios.
The objectives of this work are, over all, two: evaluate the society´s and transportation specialists the perception on the benefits, reached with the implantation of urban public transport on tracks systems and to verify if the perception of the specialists is aligned up with the perception of the society. The work was developed from a bibliographical research that had the goal to identify the benefits of the public transport on tracks. After defined the benefits the research was applied to the society using the Likert´s scale, in exploratory way, more specifically the graduation´s pupils of university courses in the metropolitan region of São Paulo in a total of 433 respondents, distributed in seven distinct places. After that was carried through a research next to transportation´s specialists, with the resource of a spread sheet for evaluation of the benefits on the basis of the Analytic Hierarchical Process - AHP. About the research with specialists, one got 34 spread sheets distributed in four distinct groups. The results show that the society and the specialists possess a sufficiently positive perception about the benefits generated for the implantation of urban public transport on tracks systems, having, however, sensible differences in the evaluations, that they reflect in the order of the benefits importance.

ENGLISH 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.

BRT is a new type of bus transit with high speed and capacity. With its advantages and benefits, BRT is getting popular in the world, including China. Since BRT and urban rail transit (URT) are both rapid public transports, the comparisons between the two will be inevitable. Generally speaking, BRT could theoretically reach the speed and capacity of light rail, but there is still a gap in abilities between BRT and metro. Though for construction investment, BRT is much lower-cost than the same-length metro, if considering the land value and exclusive effects altogether, the total cost of a BRT system could increase faster with the raise in passenger numbers. Therefore, depending on different development stages, cities should choose the right mode with highest efficiency as the dominant public transit. Sometimes, both of the systems should work in corporation for the best effectiveness. Though there are competition and substitution between BRT and URT, compatibility and complementarity also exist. The integration between the two will bring us a new understanding on the developments of the urban transit system. For integration of BRT and URT, thoughtful network planning is the first step. Second, the service quality and efficiency of transfers between the systems should be emphasized. Also important, a cooperative management will be necessary. At the same time, land development opportunities should be considered with this integration trend.

This thesis studies the open dataplatform Trafiklab, which provides openaccess to data regarding public transportin Sweden. The study is from the perspective ofthird-party developersand deals with the question of how theyvalue creating mechanisms towards themcan be improved. It is based on twodifferent surveys and severalinterviews conducted with third-partydevelopers using Trafiklab. The resultsshow that Trafiklab needs to improvetheir documentation, communication,initial use, and change theirperspective and role towards thedevelopers using Trafiklab. To improveopen data, in general, a greater focus ontransparency rather then transparency issuggested.
Detta examensarbete syftar till att skapa förbättringsförslag till en specifik typ avmjukvara utifrån använderupplevelse. Detta område är inom den öppna data branschen,öppna data innebär att man öppnar upp data så att vem som helst ta del och använda sigav den. Inom kollektivtrafikbranschen distribueras öppen data via en plattform somheter Trafiklab, som ägs gemensamt av branschens parter via en organisation mednamnet Samtrafiken. Det är inom detta område som denna uppsats försöker besvarafrågan hur Trafiklab kan bli mer värdefullt för tredjepartsutvecklare utifrån enmultidisciplinär ansats. Detta kommer att genomföras genom att både försöka ta reda påvad för värde Trafiklab idag har och hur deras nätverk gör värdeskapande möjligt.Detta projekt bestod av tre delprojekt som alla byggde på varandra. Först genomfördeen förstudie att skapa en grund för vidare undersökning presenteras teori kring öppendata och plattform. En plattform är något som skapar en grund som andra aktörer kanbygga på, ett exempel på detta är Apples iPhone där andra aktörer kan byggakomplementerande applikationer. När man har plattformer som tillhandahåller öppendata är det viktig med en balans mellan kontroll och tillgänglighet, något somsammanfattas i teorin kring ”plattform gränsresurser”. Det andra delprojektet varutformades och genomfördes av en enkät, baserat delvis på en redan genomförd enkät.Detta leda till det tredje delprokelt till mer djupgående intervjuer med enkät deltagarnaför att få en mer detaljerad bild av situationen.Resultatet från studien som helhet presenteras i form av en genomgång av Samtrafikenoch Trafiklab följt av en presentation av tredjepartsutvecklares åsikter om Trafiklab.Utvecklarnas kommentarer var i grunden positiva men det fanns områden därförbättringar skulle kunna genomföras. Detta var inom områden som dokumentation,kommunikation, förenkling att börja utveckla och Trafiklabs syn påtredjepartsutvecklare och deras relation. Detta resultat sammanfattas och diskuterassedan med hjälp av de teoretiska begreppen. Där presenteras en kartläggning avTrafiklabs plattforms ekosystem. Detta följs av en mer grundläggande teoretiskdiskussion som avslutas med att ”plattform gränsresurs modellen” appliceras ochförbättringsförslag ges.Uppsatsen avslutas med att föreslå att begreppet öppen data inte enbart betonartillgänglighet men också transparens. Detta gäller både för Trafiklab och för öppen datai Sverige generellt. Några ytterligare förslag till Trafiklab och på fortsatt intressantforsking inom området ges också som avslutning.

Natural or man-made disasters result in unfortunate events around the nation every year. Such extreme events necessitate the short-notice or no-notice evacuation of a large population from the stricken area. This research presents an optimization modeling technique to develop an evacuation plan for transit-dependent residents during no-notice disaster situation. The proposed plan relies on the application of existing public transit system of an urban area. The public transit routing plan (PTRP) problem is formulated as a mixed integer linear program. The PTRP identifies the optimal routes for transit vehicles to move evacuees from the danger zone to designated safe destinations. A heuristic TABU search algorithm is used to find high-quality solution in a reasonable amount of time. Finally, DYNASMART-P is used to evaluate the effectiveness of the developed PTRP. Numerical experiments are conducted using the traffic network of the city of Fort Worth, TX, to illustrate the proposed modeling technique.

The less glamorous aspects of a transportation system's infrastructure, such as signage, ticketing systems, and wayfinding elements, typically get little or no attention from creative professionals. Instead they are purchased directly from manufacturers as minimally customized off-the-shelf components. Paradoxically, these parts that go unconsidered and undesigned are what transit riders most directly interact with, and what most affects their experience of the transit system/product. This thesis focuses specifically on the Washington DC Metro Area Transportation Authority's (WMATA) Metrorail, aiming to reshape the entrance segment of this public transportation experience by increasing both appeal and accessibility. The design process began with primary and secondary design research, using observational and interactive methods to produce an informed picture of Metrorail users' current perspectives. A design strategy was then developed from the collective research findings, which led to a period of blue-sky ideation and finally the design of elegant and accessible mass transit entrance system components.

Background: Access to quality public transportation is critical for employment, especially for low-income and minority populations. This research contributes to previous work on equity analysis of the U.S. public transportation system by covering the 45 largest Metropolitan Statistical Areas (MSAs) and their counties. Objective: This study analyzes job accessibility of transit commuters in the 45 largest MSAs to assess the existing differences in accessibility between Census-defined socioeconomic status (SES) categories. Method: 2014 Census demographic data were matched to a previously published 2014 dataset of transit job accessibility at the Census Block Group level. Transit equality and justice analyses were performed based on population-weighted mean job accessibility and SES variables. Results: The findings suggest that within individual MSAs, the low-income populations and people of color have the highest transit job accessibility. However, in certain MSAs with high job accessibility, such as New York, Washington, D.C., Chicago, and Houston, there is a significantly disproportionate access to public transportation based on income. Variables such as income, and the use of personal vehicle, are found to have a statistically significant negative impact on job accessibility in almost all MSAs. The percentage of White workers has a significant impact on job accessibility in upper-mid-density MSAs and high-density MSAs. The percentage of the population with limited English speaking ability is not a significant determinant of job accessibility except in lower-mid-density MSAs. Disparities by income are greater than disparities by race. Racial disparities increase by MSA size and density controlling for income. The findings suggest that planning for public transportation should take into account risks, benefits, and other equally important aspects of public transportation such as frequency, connectivity, and quality of service.

In recent years, there has been a shift in focus from encouraging mobility to encouraging accessibility, along with the provision of more sustainable travel options (e.g., walking, cycling, public transport). Access to quality public transportation is critical for employment, especially for low-income and minority populations.

25 airports have a connection with the local rail transit system, but each is unique. Variables such as network size, train frequency, type of airport station, time, and cost vary by airport. Both airport passengers and planners should have a technical basis of selecting which system is the most useful, efficient, and reliable. To date, there have been no scoring procedures created to rank the airports in order of quality of connection. This thesis analyzes rail transit accessibility for all 25 airports (3 of which have 2 separate transit systems) by investigating 8 characteristics, 3 of which are market factors and 5 of which are system factors. The 5 system factors are travel time difference between car and train, transit cost difference between car and train, airport/transit connection type, network size, and train frequency. The 3 market factors are rail transit mode share, business traveler percentage, and low-cost carrier percentage. A scoring system was then developed and each airportâ s characteristics were inputted. The airports were scored using three different methods and were subsequently evaluated to understand why airports received the scores they did. This evaluation led to a better understanding of airport transit best practices. The scoring system was used again to evaluate an airport (Washington-Dulles) undergoing radical changes to understand by what factor a score can improve. A â top 10â list of airport transit connections was produced with JFK coming in first. This method is a starting point for developing a robust system to evaluate transit connections to airports.

ENGLISH ABSTRACT: The current subsidy system, designed to make South Africa’s public transport more affordable, has instead contributed to a worsening of the existent neglected state of affairs. Although subsidy policies are in place, misdirected allocation renders them mostly ineffective. The implementation of the new integrated public transport systems for metropolitan areas affords an opportunity to adopt a broad spectrum approach and initiate a redesigned and improved subsidy system. The purpose of this study is to assess the South African urban public transport industry with the aim of finding by means of a system-based process a subsidy approach that will overcome the remaining inequalities of the past. This study will consequently evaluate different subsidy theories and determine which one(s) will be best suited to the demands of a specific period. The final objective is to design a product which offers government a systembased process that will help it determine, every few years, whether the subsidy regime being applied at that juncture is still relevant to the requirements of the market and/or what (new) approach is necessary to achieve social and economic wellbeing. Commuter transport in South Africa is currently in a transition phase where new public transport infrastructure is being implemented in the metropolitan cities. The current economic recession (making people’s demand more elastic to prices) present a good time to conduct the system-based process necessary for transition of the public transport system and determine an optimal subsidy approach for the new system. The first step in the system-based process was to determine the scope of work and the overall objectives that should be reached. The main public transport shortcomings are the lack of accessibility to affordable transport for the poor and increasing private transport ownership by the rich, which increases congestion and forms the second step of the systembased process. The third step stated the action plan of strategies on how the objectives could be reached. These three steps also form the basic measurement criteria against which the different subsidy approaches needed to be tested. The fourth step in the system-based process to a better subsidy approach was to evaluate different theoretical subsidy approaches. The review of different subsidy approaches has indicated that some approaches work better than others, but an optimal subsidy system is almost never found.

ENGLISH ABSTRACT: Public and private transport system planning and operation have tended to be fragmented functions. In particular, public transport is often planned and operated independently of the "private" transport system. South African government policy now requires that comprehensive, strategic transport plans be prepared by metropolitan transport authorities. These plans are expected to conform to national strategic objectives as well as including local current and longterm objectives. This planning is required in the environment of a multi-modal, multi-operator, public-private partnership scenario that is new for most of the role players. The lack of experience is accompanied by a lack of any existing model for dealing with this scenario. This dissertation describes such a model. The model is based on the principles of strategic logistics management commonly employed in commerce and industry, including service-oriented industries. The modelling process is thus based on achieving a combination of customer service and long-term objectives. The model comprises a number of separate components and steps: • A transport network model (Emme/2). ~ A multi-class, generalised-cost assignment of private and public transport demand onto a network, modified to be modeless to the public transport users, is performed. This assignment allows for the imposition of generalised-cost reflecting urban-planning objectives in addition to more conventional costs such as travel cost. In this assignment, the interaction of public and private transport is accounted for and results in an associated modal choice. ~ A series of single-class generalised-cost assignments is then used to "focus" public transport demand to create corridors of demand adequate to justify public transport routes. This process can be enhanced to develop a design promoting switching from private to public transport. It also allows for multi-period route design. ~ The results of this modelling process are output to a text file and then subject to the processes described below. The results of these processes are then input into the network model where a standard transit assignment is performed and used to modify the proposed lines and update the network design data with respect to boardings and alightings at nodes. This information is used to design fixed infrastructure. • A Microsoft Access database and route extraction program. );> The network model data is drawn into the database where it is subject to a route extraction program that converts the assignment results from the network model into a set of mode specific potential public transport route definitions. These route definitions are based on paths of maximum demand. The extraction process is controlled by parameters specified by the planner, such as minimum route lengths and the demand level for various categories of service. );> After route extraction, vehicle allocation, and transit assignment, the database provides details of the boardings and alightings and number and details of transit lines using each node and link in the network. This data is used to design fixed infrastructure. • A Microsoft Excel spreadsheet vehicle operating cost model. );> For each vehicle type, the operating cost given the anticipated vehicle mileage and operating speed is determined. This is used to guide the choice of vehicles for different routes. • A Lingo goal-programming model. );> The potential routes and the available or potential fleet are subjected to a goalprogramme in which the optimum choice of vehicle allocation is determined. The allocation parameters can be controlled by the planner. These parameters may include costs, energy, fuel consumption, and vehicle and route limitations amongst others. Multiperiod design is included in the modelling process so that the optimum design may be for the operating period, daily, or weekly cycle. The modelling process provides two main outputs: • A set of fully described and costed transit lines ill terms of both routing and vehicle allocation. These transit line definitions can be output to the level of driver instructions if necessary. • Details of the type and location of infrastructure to be provided on the network.

Die beleid van die Suid-Afrikaanse regering vereis dat omvattende strategiese vervoerplanne deur die metropolitaanse vervoer owerhede voorberei word. Daar word van hierdie planne verwag om aan die nasionale strategiese doelwitte, asook die plaaslike bestaande en langtermyn doelwitte te voldoen. Hierdie beplanning word vereis deur 'n omgewing wat nuut is vir die meeste rolspelers en bestaan uit multi-modale, multi-operateur en openbare-private vennootskap scenario's. Die tekort aan ondervinding gaan gepaard met 'n tekort aan 'n bestaande model wat gebruik kan word om hierdie scenario's te hanteer. So 'n model word deur hierdie verhandeling beskryf. Die model is gebasseer op die beginsels van strategiese logistieke bestuur wat algemeen gebruik word in die handel en industrie, insluitende die diens-georïenteerde industrieë. Die modelleringsproses wil dus 'n kombinasie van diens aan kliënte en langtermyn doelwitte bereik. Die model bestaan uit onderskeie komponente en stappe: • 'n Vervoernetwerkmodel (Emmel2) }i;> 'n Multi-klas, veralgemeende-koste toedeling van private en openbare vervoeraanvraag op 'n netwerk, aangepas om modusloos te wees vir die openbare vervoergebruiker, word uitgevoer. Hierdie toedeling laat nie net die heffing van meer konvensionele kostes, soos reiskoste toe nie, maar ook veralgemeende kostes wat staatsbeplarmingsdoelwitte reflekteer. In hierdie opdrag word die interaksie van openbare- en private vervoer ondersoek waarvan die uiteinde 'n geassosieerde modale keuse is. }i;> 'n Reeks enkelklas veralgemeende koste toedelings word dan gebruik om op openbare vervoeraanvraag te fokus en daardeur korridors van aanvraag, wat gepas is om openbare vervoerroetes te regverdig, te skep. Hierdie proses kan verfyn word om 'n plan te ontwikkel wat die verskuiwing van private vervoer na openbare vervoer sal bevorder. Dit laat ook die ontwerp van multi-periode roetes toe. }i;> Die resultate van hierdie modelleringsproses word uitgevoer na 'n tekslêer en dan aan die prosesse, wat hier onder beskryf word, onderwerp. Die resultate van hierdie prosesse word dan ingevoer in die netwerkmodel waar 'n standaard publieke vervoertoedeling uitgevoer word. Dit word dan gebruik om die voorgestelde roetes te wysig en die netwerk data, met betrekking tot die aantal persone wat op en af klim by nodes, op te dateer. Hierdie inligting word gebruik vir die ontwerp van infrastrukture. • 'n Microsoft Access databasis en roete-ontrekkingsprogram );> Die netwerkmodel data word in die databasis ingetrek waar dit aan 'n roeteontrekkingsprogram onderwerp word. Hierdie program skakel die toedelingsresultate van die netwerkmodel om na 'n stel potensiële modus spesifieke openbare vervoerroete definisies. Hierdie roete definisies word gebasseer op paaie van maksimum aanvraag. Die ontrekkingsproses word deur parameters, soos minimum lengte van roetes en die vlak van aanvraag van verskeie kategorieë van diens, wat deur die beplanner gespesifiseer word, gekontroleer. );> Na die ontrekking van roetes, voertuigtoekenning en vervoertoedeling, voorsien die databasis besonderhede van die aantal persone wat op en af klim asook die aantal en details van vervoerroete wat elke node en skakel in die netwerk gebruik. Hierdie data word gebruik om infrastrukture te ontwerp. • 'n Microsoft Excel sigblad voertuig bedryfskoste model )i> Vir elke tipe voertuig word die bedryfskoste, volgens die verwagte afstand en spoed van die spesifieke voertuig, bepaal. Die resultate word gebruik om die keuse van voertuie vir verskillende roetes te bepaal. • 'n Lingo doelprogrameringsmodel );> Die potensiële roetes en die beskikbare of potensiële vloot word onderwerp aan 'n doelprogram waarin die optimum keuse van voertuigtoekenning bepaal word. Die toekenningsparameters kan deur die beplanner gekontroleer word. Die parameters kan onder andere kostes, energie, brandstofverbruik en voertuig- en roete beperkings, insluit. Multi-periode ontwerp is ingesluit in die modelleringsproses sodat die optimum ontwerp vir die bedryfsperiode, daaglikse of weeklikse siklusse, kan wees. Die modelleringsproses lewer twee hoofuitkomste: • 'n Stel volledig beskrywende en koste berekende vervoerroete wat, indien nodig, na die vlak van bestuurder instruksies, uitgevoer kan word. • Details van die tipe en plek van infrastruktuur wat benodig word deur die netwerk.

O presente trabalho propõe a implantação de um sistema de consulta por telefone para usuários de transporte coletivo, baseado num Sistema de Informações Geográficas (SIG), oferecendo dentre outras informações referentes ao sistema de transporte público, as rotas ótimas entre origens e destinos informados pelos passageiros. Este sistema se fundamenta em uma base de dados ampla e atualizada, com uma grande gama de informações sobre a rede de transporte público, incluindo: cadastro de logradouros, malha de circulação viária, pontos de parada e itinerários de linhas de ônibus. Escolheu-se como estudo de caso o sistema de transporte coletivo da cidade de São Carlos - SP, cujas principais informações foram obtidas na forma cartográfica e transferidas para o formato digital, via mesa digitalizadora e através de rotinas específicas do software. Os dados espaciais e atributos, necessários a aplicação do sistema proposto, foram processados em um software para SIG, denominado TransCAD, que constitui uma poderosa ferramenta de planejamento, gerência, operação e análise de sistemas de transporte. Os resultados aqui obtidos indicam que é viável implementar um sistema de consulta dessa natureza em cidades de porte médio, sem grandes investimentos, desde que haja interesse, mão-de-obra qualificada e um treinamento prévio dos técnicos que irão operá-lo, como condições essenciais para o sucesso do projeto.
The purpose of this study is to proposes the implementation of a transit information system based on a Geographic Information System (GIS). The new system is designed to offer information by telephone about the public transportation system, such as the optimal paths between the origins and destinations provided by the system\'s users. This query system is based on a broad and updated database, which contains a large amount of information on the city\'s transit network, including the names of all the city\'s street, the network of streets accessible by bus, bus stops and routes. The public transportation system of the city of São Carlos, located in the state of São Paulo, was selected for a case study. Both spatial and nonspatial data needed for the application of the proposed system were processed in the same GIS software, called TransCAD, which is a powerful tool for planning, management, operation, and analysis of transportation systems. The basic geographic information has been transferred from printed maps - the main sources of this type of data - to digital format with the help of software routines and a small digitizing tablet. The results obtained in this study suggest that the system can be easily implemented in medium-sized brazilian cities, without the need for significant investments. The basic requirements for the success of this kind of project are as follow: a qualified staff to implement the system, and some prior training for the technician who is going to operate the system.

Le choix d'un système de transport guidé de surface exploité en site propre (TCSP) est un travail complexe et difficile. Les différents systèmes peuvent sembler offrir des services équivalents pour les utilisateurs tandis que manquent souvent les informations nécessaires pour mieux distinguer les différences entre tel ou tel système. L'objectif de cette recherche vise, au-delà d'une présentation des différents systèmes guidés de surface qui structurent les réseaux de transport public en France, à procéder à une analyse comparative afin de mieux guider les choix des collectivités territoriales, dans le contexte des efforts qu'elles conduisent pour promouvoir des transports urbains répondant aux enjeux du développement durable. Les avantages et points faibles de chaque système est analysé et présenté de manière désagrégée. De manière complémentaire, est proposée et discutée une méthode multicritère ELECTRE III permettant d'agréger les résultats obtenus et de proposer le (ou les) système(s) le(s) mieux adapté(s) à différents contextes d'exploitation. Le résultat principal met en évidence le fait que le tramway moderne sur fer occupe une place privilégiée dans la majorité des scenarii. Cependant, le CIVIS, le Translohr, TVR et même le trolleybus ont leur place selon le contexte d'exploitation, dès lors en particulier que sont pris en compte les coûts d'infrastructure et d'exploitation associés. Les résultats de cette recherche nous encouragent en outre à recommander, chaque fois qu'il y a un projet de système de transport de surface, de passer en revue la gamme des systèmes et d'effectuer l'analyse comparative avec les différentes contraintes du lieu et du moment, en y intégrant une vision de moyen et long terme et les effets prévisibles sur l'aménagement urbain
The choice of a guided surface transit system operated on separated RoW is a complex and difficult task. Even if different transit systems could provide equivalent services to users, we often lack the necessary information to better distinguish among different systems. Beyond giving a presentation of different surface guided systems structuring the public transport networks in France, the aim of this research is to conduct a comparative analysis in order to better guide decisions of local authorities in their efforts to promote urban transport that meets the challenges of sustainable development. The advantages and the drawbacks of each system are analyzed and presented in a disaggregated way. In addition, a multicriteria method ELECTRE III is proposed and discussed for aggregating the results and proposing system(s) best suited for different operating conditions. The main result shows that the modern tramway on rail occupies a privileged place in most scenarios. However, the CIVIS, Translohr, TVR and even trolleybuses have their places with respect to operating conditions, given that the related infrastructure and operating costs are taken into account. The results of this research therefore encourage us to recommend, every time we propose a surface transit system, to review the whole range of systems and to do the comparative analysis with different context and time constraints integrating mid-term and long-term visions and predictable effects on the urban requalification

Les hommes, dès leur naissance, et de fait après leur entrée dans le monde, ont des devoirs et des droits, un fait inhérent à ce monde. L’existence du droit de vivre et des devoirs humains d’un côté, et la puissance de posséder et de transmettre les possessions de l’autre côté, démontre le besoin de fondation d’un système juridique. La mort au sens juridique, c’est la fin de l’existence des personnes, le phénomène qui cause la rupture entre la personne et ses biens. Certes, ce phénomène arrive indubitablement, et alors se pose la question des biens notamment sans possesseur.On entend littéralement par « héritage », tous les biens et les choses personnels qu'une personne décédée laisse derrière elle ou tout ce qui est soumis à l'héritage dans les biens d'une personne décédée. Dans les termes du droit, l'héritage est défini comme le transfert inéluctable des biens d'une personne décédée à ses parents et à ses proches, selon des conditions particulières (de la société). Le transfert des biens d'une personne dès son décès est une chose ancienne qui s'enracine dans les premières civilisations humaines. Depuis le moment où la famille au sens premier du terme fut fondée, jusqu'à la forme qu'elle a aujourd'hui, le transfert des biens d'une personne décédée à ses proches a un aspect légal qu'on peut rencontrer au sein de différentes sociétés. L'héritage est un terme provenant de la nature intrinsèque de l'homme, mais il ne faut pas pour autant ignorer que pour différentes sociétés, il se définit conformément aux us et coutumes et aux croyances relatives à l'héritage défini par les règles instituées sur les biens privés.L'héritage est un droit naturel. Il est possible que plusieurs personnes pensent qu'il serait meilleur, au moment du décès, que leurs biens fassent partie des biens publics et qu'ils soient à la disposition du trésor public. Néanmoins, si on y réfléchit attentivement, il devient clair que cette position nous éloigne de la justice, car le sujet de l'héritage est un fait tout à fait naturel et logique, de la même manière que le père et la mère transmettent une partie de leurs traits physiques et moraux suivant les lois de l'héritage naturel.Mots-clés : posséder, transmettre, possession, système juridique, bien, décédé, héritage, la famille, droit naturel, trésor public
It is a truth common to all that from their birth onward, on entering this world, men have rights and obligations. The existence of the right to live and the human obligations on one side and the power to possess and transmit one’s possessions on the other side prove the need to establish a legal system. On a judicial level, death is the end of someone’s existence, the cause for the separation between someone and his goods.Since death occurs to all of us, what happens to possessions whose owner is unknown? The notion of heritage encompasses all the goods and personal objects which a deceased one leaves behind or all the goods of a deceased one which are to be inherited. In terms of law, heritage is understood as the definitive transfer of the goods of a deceased to his parents or his kids under the specific conditions of his society. The transfer of goods of someone who has just died is ancient and stretches back to the first human civilizations. From the time of the primitive form of the family to its current shape, and among the different kinds of societies, there has been a legal aspect to the transfer of a deceased one to his kids. The notion of heritage is inherent to man’s nature. But one must not forget that habits and customs vary from society to society. Thus the creeds related to heritage define the rules related to private goods.Inheriting is a natural right. Some may believe that it would be better that the goods of a deceased be integrated into the common property and be kept at the disposal of the Treasury.Nevertheless, after more thorough thinking, this point of view appears to be far from being just, since heritage is completely natural and logical, like the transmitting of some of one’s parents’ physical and moral traits is, according to the natural heritage

This study aims to develop an analytic model for exploring the optimal fare and level of service of an intermodal public transit system, where mass rapid transit (MRT) and feeder bus transit systems are coordinated. An integrated fare for feeder bus and mass rapid transit services as well as feeder bus headway are optimized under the maximum social welfare objective with a break-even constraint. The relationships between the decision variables and the parameters of system supply and demand are also analyzed. In the past, most public transit studies analyzed the fare and other decision variables for only a single public transit system and generally ignored the interrelationships and integration between various public transit systems. Additionally, the pricing scheme of public transit normally applied the average costing method rather than demand variation that may be caused by fare and level of service. This study develops a model to solve the optimal MRT fare, feeder bus headway, and feeder bus fare simultaneously. To consider the solution process of the model and the validity of optimal results, numerical examples and mathematical programming are applied to obtain the optimal solutions. Different scenarios of the size, numbers, and potential demand of feeder bus zones are analyzed and discussed. It is worth of noting that the model developed is a general form representing a typical MRT station with various feeder bus routes while the optimal MRT fare is based on an average trip length. Therefore, basic fare rate can be obtained by the optimal fare and average trip length and then the fare of any station may be analyzed accordingly. It is shown from numerical results that the fare ratio for MRT passengers transferred from feeder bus service is about 1.021 compared with basic MRT fare. In other words, the marginal cost of MRT system is significantly small with that of feeder bus; therefore the maximum social welfare of the integrated system can be achieved with an almost free feeder service. It appears that the MRT revenue can not only support MRT service but also provide feeder bus system and then help of fully utilizing the capacity of MRT. The model and numerical analyses in this study can be used as a guideline for management of an integrated MRT and feeder bus systems.

The whole framework of planning and designing for mass transportation system has been significantly transformed by virtue of Advanced Public Transportation System (APTS) and Advanced Traveler Information System (ATIS). Because of the two influential mechanisms, the operational efficiency of mass transportation service providers has been improved, the incidence of traffic jam has been reduced, and passengers can have access to real-time travel information. Moreover, the two systems are also used to change Transit Trip Assignment so that the passenger’s route selection can be altered to meet his or her needs. The application of APTS and ATIS greatly influence the selection of transit modes and Transit Trip Assignment, especially in a city with various transit options. Under the two systems, the bus dispatching station can arrange transfers and adjust headways according to the arrival time of buses. Furthermore, in a city with MRT and bus transportation system can be provided with instant information about transfers, the estimated arrival time of the target transit mode for transfer and the choices of transit modes. In terms of management and operation, trip assignment analysis can show the changes of each route’s passenger traffic and forecast the influences on the bus transportation system when a new system comes into play. Therefore, the variation of passenger traffic can be under control before the new system starts so that the operation plan of the multi-modal transportation system is more capable of satisfying O-D demand. The main focus of this present study is Trip Assignment Model for Multi-modal Advanced Public Transit Systems. The factors which influence the selection of transit modes and routes under APTS and ATIS are taken into consideration. Threshold Value theory is take advantage of to eliminate the trips which don’t need a transfer from bus to MRT by considering the difference of the number of transfers, ticket price cost, waiting time and in-vehicle time. Then ATIS concept is conducted to recalculate passenger’s total travel cost. Based on Minimum Path Cost Theory, the passenger will choose the path with the lowest cost. Therefore, the establishment of trip assignment model is completed. This study simulates a route network to test Trip Assignment model for Multi-modal Advanced Public Transit Systems in Kaohsiung city, and applies four operation models respectively with or without information system and with or without ticket price discounts to the network for analysis. This study finds that without dynamic information system, up to 22.6% of bus passenger traffic will be transferred to MRT, but with dynamic information system, about 10% of transfers are deductible. The current ticket price discounts don’t have any influence on traffic transfer. With information system, 59% of passenger’s total travel cost can be saved. Nevertheless, if the bus travel time is too long, the bus route and the MRT path are parallel or overlapping, the bus route is too curvy, or the bus station and the MRT station are located at the same place, the bus passenger traffic may be transferred.

Among various subsystems in Intelligent Transportation Systems (ITS). develop ment of public transit system and Advanced Public Transit Systems (APTS) have higher priority. The decision makers and system developers were constrained in the situation of technology-oriented development philosophy and neglect the users* functional requirements in APTS development. There lacks of systemati c ITS and APTS planning and design methodology. The system developers usually design the service functions by their own intuition without considering the function needs of real system users. In order to having a reliable, efficient , and sustainable APTS, the purpose of this study is to develop the process a nd related methodologies of the system planning of APTS based on the user-orie nted approach. The integration and assessment of advanced technologies are al so included in the research. The contents of this dissertation are priority as sessment of functional requirement, priority evaluation of technology requirem ent, planning system framework & analysis of user interface, and the assessmen t of advanced technologies. An intercity bus system is used in the case stu dy. The results of the case study verify the applicability of the methodology developed.

Dhaka is the capital city of Bangladesh and the centre of administrative, political, economic and social life for the country. An efficient transit system is needed in this city to provide services in every corner and to the people of all socio economic standing. This city is characterized by both motorized and non-motorized transport services, though there is a huge demand on the bus transit system. Dhaka is also one of the fastest growing global cities, which is contributing to even higher transit demand. There is a need, therefore, to investigate the present transit system with a view to understand the opportunities and potential of the current public transport system given available policy support and resources. This research is an initiative to identify the current efficiency status of transit services and explore the opportunities to increase the efficiency of this system for the people of this mega city. To carry out this research, along with literature and policy review, interviews with stakeholders and a survey of transit operators was undertaken. From the analysis of the operator’s survey and literature review, the current underperforming status of transit services was identified. From the discussion of interviews and policy frameworks, strategies to improve the current status and guidelines for future initiatives are outlined. This includes a separate and powerful institutional authority solely for transit services and taking regulatory measures by this authority to speed up STP implementation. For bus transit only, the recommendations are: consolidating bus industry and exclusive bus lanes to improve current status of bus transit service. Finally by achieving and fulfilling the recommendations of this study, it is hoped that a more efficient transit system in Dhaka city would result.

Public transit is considered a cost-effective alternative to mitigate the effects of traffic gridlock through the implementation of innovative service designs, and deploying new smart systems for operations control and traveller information. Public transport planners use transit assignment models to predict passenger loads and levels of service. Existing transit assignment approaches have limitations in evaluating the effects of information technologies, since they are neither sensitive to the types of information that may be provided to travellers nor to the traveller’s response to that information. Moreover, they are not adequate for evaluating the impacts of Intelligent Transportation Systems (ITS) deployments on service reliability, which in turn affect passengers’ behaviour. This dissertation presents an innovative transit assignment framework, namely the MIcrosimulation Learning-based Approach to TRansit ASsignment – MILATRAS. MILATRAS uses learning and adaptation to represent the dynamic feedback of passengers’ trip choices and their adaptation to service performance. Individual passengers adjust their behaviour (i.e. trip choices) according to their experience with the transit system performance. MILATRAS introduces the concept of ‘mental model’ to maintain and distinguish between the individual’s experience with service performance and the information provided about system conditions. A dynamic transit path choice model is developed using concepts of Markovian Decision Process (MDP) and Reinforcement Learning (RL). It addresses the departure time and path choices with and without information provision. A parameter-calibration procedure using a generic optimization technique (Genetic Algorithms) is also proposed. A proof-of-concept prototype has been implemented; it investigates the impact of different traveller information provision scenarios on departure time and path choices, and network performance. A large-scale application, including parameter calibration, is conducted for the Toronto Transit Commission (TTC) network. MILATRAS implements a microsimulation, stochastic (nonequilibrium-based) approach for modelling within-day and day-to-day variations in the transit assignment process, where aggregate travel patterns can be extracted from individual choices. MILATRAS addresses many limitations of existing transit assignment models by exploiting methodologies already established in the areas of traffic assignment and travel behaviour modeling. Such approaches include the microsimulation of transportation systems, learning-based algorithms for modelling travel behaviour, agent-based representation for travellers, and the adoption of Geographical Information Systems (GIS). This thesis presents a significant step towards the advancement of the modelling for the transit assignment problem by providing a detailed operational specification for an integrated dynamic modelling framework – MILATRAS.
