Book excerpt: Doctoral Thesis / Dissertation from the year 2015 in the subject Transportation Science & Technology, , course: Transit planning, language: English, abstract: Transit route Network Design Problem (TrNDP) is the most important component in Transit planning, in which the overall cost of the public transportation system highly depends on it. The main purpose of this study is to develop a novel solution methodology for the TrNDP, which goes beyond pervious traditional sophisticated approaches. The novelty of the solution methodology, adopted in this studyr, stands on the deterministic operators which are tackled to construct bus routes. The deterministic manner of the TrNDP solution relies on using linear and integer mathematical formulations that can be solved exactly with their standard solvers. The solution methodology has been tested through Mandl’s benchmark network problem. The test results showed that the methodology developed in this research is able to improve the given network solution in terms of number of constructed routes, direct transit service coverage, transfer directness and solution reliability. Although the set of routes resulted from the methodology would stand alone as a final efficient solution for TrNDP, it could be used as an initial solution for meta-heuristic procedures to approach global optimal. Based on the presented methodology, a more robust network optimization tool would be produced for public transportation planning purposes.

Available in PDF, EPUB and Kindle. Book excerpt: A new bus transit planning tool is developed for application in determining operating policies of a fixed-route bus transit system. The objective of the study is to model a bus transit system which functions under time-varying passenger demands and service characteristics. The two phase transit model developed in this research is intended for use as a mass transit planning tool, to solve transit problems confronting the mass transit planner. The model is used to compute cost differentials in transit system options. These alternatives of expanding, abandoning or modifying service depend upon the service frequency, fleet size and other system attributes such as operating speed, delay, passenger demand and relevant cost factors. The model is formulated in two phases, jointly utilizing linear and dynamic programming techniques. It is directed toward optimizing transit operation during one period and then aggregating each operation over the range of transit service periods. The basic components of system function to be optimized (minimal total cost) include such variables as bus operating and ownership costs, passenger costs in terms of walking, riding, and transfer times as well as bus fares. The transit model has been programmed for a digital computer. This model requires inputs of existing street configuration and bus routes, bus schedules, speed and delay data for street networks, fare structure, load factor and passenger Origin-Destination information for different periods. A practical application of the transit model is presented in the format of a case study. This application illustrates the utilization of the methodology for deriving bus transit operating policies and the consideration of planning alternatives. The result of a comparison of these policies and alternatives is a significant reduction in the total system cost. Special emphasis has been given to the analysis of the structural elements involved in a transit system as well as new transit planning techniques. There follows a summation of the findings and the implications of the results. This summary includes an appraisal of the model as to its limitations as well as recommendations for future research. The appendix, finally, lists a summary of notations review of previous research, flow charts and listings of computer programs, supplemental data, computer input and output files, and an annotated bibliography containing current literature concerning the operation and planning of public transportation.

Book excerpt: The problem considered in this thesis is bus routing in terms of route location choice in response to bus user markets in urban areas. Bus service sustainability which is under threat constitutes the study background. This study establishes a market-oriented bus routing strategy able to resolve the dilemma between the poor economic sustainability, societal demands and benefits from the services. Empirical bus routing practices are typically set in an operation-oriented bus routing framework. The major characteristic of the operation-orientation is the direct use of mathematical routing methods to minimise routing costs and so determine route location. A shortest route linking a route origin with a route destination is usually the outcome. The users residing within the service areas now bypassed by the direct route are ignored. This study suggests that this loss of bus patronage subsequently leading to poor economic sustainability is due to inappropriate geographical distribution of services, re-locating routes can influence the chances of travellers using bus services, and market-oriented bus routing can improve the service sustainability by linking where bus users want to go with where they come from. The bus routing strategy in terms of a market-oriented framework can be used for planning fixed bus routes where a number of criteria in addition to the usual operational constraints are considered. In particular, the market-orientation emphasises the study of bus user markets. A 'satisficing' or acceptable routing solution rather than a cost-optimal solution is sought. The `satisficing' solution derives from a trade-off or compromise among bus users needs and bus operators' requirements. The market-oricnted routing framework is based on theory from several disciplines. It adopts 'satisficing' theory in a geographical spatial environment and links route optimisation methodology from engineering and customer profiles from marketing. This study progresses research by these links. The three major aspects are: 1. Bus users are studied through the application of market analysis principles and techniques of and geographical market segmentation. 2. Mathematical routing methods for searching for a shortest path and a facility location are applied for laying out bus routes, guided by bus user markets and 'satisficing' principles. The facility model operates to find key user market locations, and the shortest path model operates to lay out a route passing through these key market locations. 3. The established Geographic Information System (GIS) works as an information platform for both organising the database and implementing the market analysis and the routing methods. The routing framework proposed in this study is examined in cases in Inner Western Sydney. The first part of the examination is the use of census data and home interview survey data to explore the characteristics of bus commuter markets and bus travels. The second part is the demonstration of the routing effectiveness in terms of market patronage potential increments within the service catchment areas of the routing alternatives. The Strength, Weakness, Opportunity and Threat (SWOT) of the routing alternatives suggested in the case studies are analysed. The final routing alternatives show the characteristics of acceptable routing solutions and the application of the principle of compromise. They also show that the routing strategy has the elements of customer orientation in terms of residential socio-demographics and competitor orientation in terms of geographic locations in the market definition. Future study areas for bus routing include the incorporation of information on all travel purposes, the addition of specific information on road networks, the assistance to designing bus route networks, and the introduction of travel choice behaviour theory to study the compromise between users needs and operators requirements.

This book was released on 2011 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: For long time, most of the big cities have serious problems of congestion in the streets because of the high use of private vehicles, which means also more pollution and traffic accidents, among others. Therefore, for over many years ago and up to nowadays has been investigating in order to improve the quality and service of the public transportation and thus make it more attractive for the people. Since the people spend very much time going to work, university, etc., a very important aspect for the traveller is his travel time. This includes the time going to and from the bus stop, waiting and travel time. These times may be optimized and reduced with and effective route and with a good commercial speed of the bus as well. This project is focused on investigating some aspects of transport engineering of the urban bus route number 43 of the city of Kaunas, Lithuania. In order to do it, the study is performed for several time periods in a weekday and on Saturday. The research intends to analyze four factors: the speed of the vehicle along the route, the passenger's flow, the passenger travel distance and the passenger travel time. In the experimental research it is obtained data of passengers flow throughout the route; and, in order to get data of bus speed we have a GPS which is able to store files at high frequency. The results indicate that the vehicle speed is not affected by the load; however it might be significant when comparing average bus speeds of the streets. The calculations give an average travel distance on the vehicle equal to 4,79 km and an average travel time - including walking and waiting time - nearly 24 minutes. About passengers' flows, they are localized in a small time interval during the morning peak time. However, in the afternoon the passengers come back home during more prolonged time and often without peaks of flow.

Book excerpt: Abstract: The Bus Location Information System (BLIS) was conceived, developed, and implemented by researchers and students in Civil and Environmental Engineering and Electrical and Computer Engineering for the Campus Area Bus Service (CABS), the Ohio State University transit system. Campus buses were fitted with Global Positioning System (GPS) units, which determine latitude and longitude coordinates of the receiver at a given time -- and, therefore, the coordinates of the bus on which the receiver is installed -- by triangulating among a series of signals transmitted from a set of satellites. These locations are communicated to a central server, where they are translated into distances along bus routes with respect to each route's reference point. The various location and time points can be organized to produce bus trajectories, which can be plotted in what is known as a space-time diagram. With these space-time coordinates, speeds of the buses as they traverse the route can be calculated. These speeds can be analyzed to determine what effect time has on speed (i.e. time of day, day of week, month of year), what effect space has on speed (looking at speeds within context of surrounding roadway infrastructure), and the simultaneous impact of time and space on the speeds of the buses. It was found that while the time of day has less impact on the speed than the location, there are patterns throughout both the day and along the route. It was also found that the time and space factors do not always act independently. Also, many of the patterns could be explained by examining the surrounding infrastructure features including stop lights and signs and bus stops, but some could not. The speed information extracted and the patterns identified could be beneficial in several ways. First, they could be used for better off-line transit planning including route and schedule design. Second, if the data is collected in real-time, the results could be useful for real-time bus control and the provision of bus travel time and arrival information to passengers. Finally, the results could complement information extracted from other sensors for the purpose or real-time management of overall transportation networks including private automobile, commercial vehicle, and public transit flows.
