Download or read book Modelling Public Transport Passenger Flows in the Era of Intelligent Transport Systems written by Guido Gentile and published by Springer. This book was released on 2016-02-03 with total page 671 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book shows how transit assignment models can be used to describe and predict the patterns of network patronage in public transport systems. It provides a fundamental technical tool that can be employed in the process of designing, implementing and evaluating measures and/or policies to improve the current state of transport systems within given financial, technical and social constraints. The book offers a unique methodological contribution to the field of transit assignment because, moving beyond “traditional” models, it describes more evolved variants that can reproduce:• intermodal networks with high- and low-frequency services;• realistic behavioural hypotheses underpinning route choice;• time dependency in frequency-based models; and• assumptions about the knowledge that users have of network conditionsthat are consistent with the present and future level of information that intelligent transport systems (ITS) can provide. The book also considers the practical perspective of practitioners and public transport operators who need to model and manage transit systems; for example, the role of ITS is explained with regard to their potential in data collection for modelling purposes and validation techniques, as well as with regard to the additional data on network patronage and passengers’ preferences that influences the network-management and control strategies implemented. In addition, it explains how the different aspects of network operations can be incorporated in traditional models and identifies the advantages and disadvantages of doing so. Lastly, the book provides practical information on state-of-the-art implementations of the different models and the commercial packages that are currently available for transit modelling. Showcasing original work done under the aegis of the COST Action TU1004 (TransITS), the book provides a broad readership, ranging from Master and PhD students to researchers and from policy makers to practitioners, with a comprehensive tool for understanding transit assignment models.

Download or read book Distribution based Approach to Take Advantage of Automatic Passenger Counter Data in Estimating Period Route level Transit Passenger Origin destination Flows written by Yuxiong Ji and published by . This book was released on 2011 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: Abstract: A methodology is developed to estimate a route-level probability OD flow matrix for a time-of-day period that takes advantage of the increasing availability of large quantities of boarding and alighting data collected via Automatic Passenger Counter (APC) technologies. Unlike previous transit OD estimation approaches, the problem formulation considers the distribution, rather than only the means, of the APC data. A Heuristic Expectation Maximization (HEM) algorithm is developed to provide an approximate solution to the estimation formulation while achieving computational feasibility for applications to realistically long bus routes. The performance of the HEM algorithm is evaluated numerically and empirically by comparing OD flow estimates to estimates produced by three other methods: the Expectation Maximization (EM) method, the Iterative Proportion Fitting (IPF) method and a Conditional Maximization (CM) method. The EM method provides a solution to the formulation, but it is computationally prohibitive for practical use. The IPF method represents traditional methods, where only the means of the APC data are considered. The CM method is developed in this study as another computationally feasible method that considers the distribution of APC data, but it is seen to extract information on the probability OD flows less efficiently than the HEM method. The numerical study demonstrates that the HEM algorithm provides a good approximation to the solution produced by the EM algorithm. In addition, the numerical and empirical studies demonstrate that the HEM algorithm produces more accurate estimates than the IPF and CM methods when large quantities of APC data are available. Moreover, the numerical and empirical studies quantify the effects of three pertinent factors on the accuracy of OD flow estimates: the number of bus trips with APC data, the sample size of an OD flow survey used with APC data to estimate OD flows, and the magnitude of measurement errors in APC counts. The HEM algorithm does not work particularly well when only a few bus trips have APC data. However, the improvement in the quality of the estimates produced with increased quantities of APC data when using the HEM method is greater than when using the CM method and is much greater than when using the IPF method. The numerical studies further demonstrate that the HEM method outperforms the IPF and CM methods if the number of bus trips with APC counts is larger than a certain threshold. This threshold increases with the sample size of an OD flow onboard survey if such a survey is used in the estimation. The threshold also increases with increasing magnitude of measurement errors in APC counts. Nevertheless, the threshold is relatively small compared to what can be feasibly collected from APC-equipped buses. Additional properties of probability OD flow estimation using the HEM algorithm are also investigated, such as convergence of the algorithm, sensitivity of OD estimates to the underlying OD structure and the distributional assumptions, and performance of OD estimation under congested conditions on buses due to bus bunching and high demand.

Available in PDF, EPUB and Kindle. Book excerpt: Over the time, Intelligent Transport System (ITS) has become important for any country not only for traffic congestion management, but also for modern infrastructure and safety. Since there is a dearth of literature on this subject, this book attempts to fill the gap and provides a holistic work on ITS encompassing theory, examples and case studies on various facets in both road and railway sectors. The basic principles of various technologies used for ITS have been explained in such a manner that students from non-technical background can also comprehend them with ease. It also discusses the emerging technologies such as autonomous vehicles, electric vehicles, cooperative vehicle highway system, automated highway systems, 5G mobile technology, etc. Considering the need of huge funds required for ITS implementation, the text provides various funding options available. Conclusively, it is a unique book that contains all aspects of ITS which a student of engineering is expected to know. The book is intended as a text for postgraduate students of transportation engineering and as a reference book for professionals such as transport planners, town planners, traffic engineers, transit operators and consultants. Key Features, • ITS architecture with a number of case studies based on real-life situation • Concept of smart city, importance of advanced transport system, and applications of ITS technologies in smart cities • ITS in Rail sector—intelligent trains, train control systems and intelligent train maintenance practices • Chapter-end questions for practice and bibliography

Download or read book Computer Aided Transit Scheduling written by Martin Desrochers and published by Springer Science & Business Media. This book was released on 2012-12-06 with total page 432 pages. Available in PDF, EPUB and Kindle. Book excerpt: This volume consists of papers presented at the Fifth International Workshop on Computer Aided Scheduling of Public Transport, which was held in Montreal from August 19th to the 23rd, 1990. Since the first Workshop in Chicago in 1975 the field had matured considerably. In 1975, there were no presentations that described systems which had been implemented and used on a regular basis. By 1980, in Leeds, and certainly by 1983, in Montreal, several systems were in regular use. They were based on both heuristics and mathematical programming techniques. In 1990, there were more than one hundred transit companies using computer-aided scheduling tools in their regular operations. The scope of the Workshop was broadened in 1987, in Hamburg, so that topics related to scheduling may be introduced. We find, for example, in this book several papers on the technology related to the collection of data and/or the data bases required for scheduling and planning activities.
