Book Description
Technological advances in the transit industry, such as the introduction of Automatic Vehicle Location (AVL) systems, have provided agencies with robust data collection and measurement systems and enabled the development of comprehensive planning and operations tools. This thesis reviews the impact of an AVL installation in London, and demonstrates how data recorded by this system may be used to improve service reliability and operations planning on the London bus network. In particular, this thesis focuses on capabilities which would have been impossible prior to the installation of AVL. Service reliability has traditionally been measured from an operations perspective despite a major objective of the transit agency being to provide high quality service to passengers. A framework for a service reliability analysis is developed which explores new passenger-centric measures used to describe the quality of transit service, which are measured with AVL data. First, an analysis of trends in service reliability and factors that contribute to service reliability is performed in order to gain a better understanding of the environment in which transit services are operated. Three new passenger-centric measures of reliability are then introduced which describe the entire bus passenger experience. These measures are evaluated for a set of origin/destination pairs on six bus routes, and the differences in the perception of reliability between the new measures and the traditional measures are identified. The analysis demonstrates that while the traditional measures of reliability are relevant, the new measures provide additional insight. Recommendations are made with regard to implementing these new measures, providing better passenger journey information by applying these measures, and improving service control practices by monitoring these measures. AVL data provides for the development of more robust operations plans since these data allow for a greater degree of accuracy when measuring point to point running times. A framework is presented for how running times measured with AVL may be used to assess the efficacy of current operations plans and aid operations planners in vehicle scheduling. Recommendations are made with regards to how AVL data should be used to evaluate the effectiveness of existing schedules and develop more robust schedules.

Book Description
Bus Rapid Transit (BRT) is increasingly being discussed as an affordable way for cities to build sustainable rapid transit infrastructure. This is the first book to examine the opportunities presented by BRT along with the significant challenges cities face in the implementation of successful systems. The difficulties can be myriad: new institutional relationships have to be developed among governments, operators, and the public; projects have to be designed and implemented to handle large passenger flows in the most efficient manner possible; and these changes are not taking place on a blank slate, but within existing transportation systems, political and cultural contexts, and urban development patterns. Addressing these challenges from an international perspective and across a range of disciplines, from urban planning to public policy and economics, contributors offer technical solutions to specific problems and identify what still needs to be done to realize their vision of global sustainable transport.

Book Description
Viewing transportation through the lens of current social, economic, and policy aspects, this four-volume reference work explores the topic of transportation across multiple disciplines within the social sciences and related areas, including geography, public policy, business, and economics. The book’s articles, all written by experts in the field, seek to answer such questions as: What has been the legacy, not just economically but politically and socially as well, of President Eisenhower’s modern interstate highway system in America? With that system and the infrastructure that supports it now in a state of decline and decay, what’s the best path for the future at a time of enormous fiscal constraints? Should California politicians plunge ahead with plans for a high-speed rail that every expert says—despite the allure—will go largely unused and will never pay back the massive investment while at this very moment potholes go unfilled all across the state? What path is best for emerging countries to keep pace with dramatic economic growth for their part? What are the social and financial costs of gridlock in our cities? Features: Approximately 675 signed articles authored by prominent scholars are arranged in A-to-Z fashion and conclude with Further Readings and cross references. A Chronology helps readers put individual events into historical context; a Reader’s Guide organizes entries by broad topical or thematic areas; a detailed index helps users quickly locate entries of most immediate interest; and a Resource Guide provides a list of journals, books, and associations and their websites. While articles were written to avoid jargon as much as possible, a Glossary provides quick definitions of technical terms. To ensure full, well-rounded coverage of the field, the General Editor with expertise in urban planning, public policy, and the environment worked alongside a Consulting Editor with a background in Civil Engineering. The index, Reader’s Guide, and cross references combine for thorough search-and-browse capabilities in the electronic edition. Available in both print and electronic formats, Encyclopedia of Transportation is an ideal reference for libraries and those who want to explore the issues that surround transportation in the United States and around the world.

Book Description
The 17 chapters in this book, which evolved from a conference on measuring the contributions of ITS sponsored by the California Department of Transportation in February 2002, examine the costs and benefits of ITS in an economic and business policy context. Section 1 examines the broad theme of how and what ITS contributes to the economy and how one makes a business case for ITS. Section 2 includes three chapters on ITS applications in mass transit. Section 3 explores ITS applications in the automobile/highway system. Section 4 considers integrative issues including how ITS is perceived and how it can be positioned to improve surface transportation. This volume will be especially useful to researchers and policy makers working in transportation, transportation engineering, and the economic analysis of transportation systems.
