Since 1978, the Essential Air Service (EAS) program has subsidized air service to eligible communities that would otherwise not have scheduled service. The cost of this program has risen as the number of communities being served and subsidies to air carriers have increased. At the same time, the number of carriers providing EAS service has declined. Given continuing concerns over the EAS program's long-term prospects, this report reviews: (1) the characteristics and current status of the EAS program; (2) factors affecting the program's ability to provide air service; (3) options for revising the program; and (4) tools for assessing the program, the options for its revision, and the program's performance.

This progress report describes the development of the NTS initiative and proposed future activities to bring the NTS to its full potential. A set of preliminary national transportation performance indicators is proposed. These performance indicators should be seen as the beginning of a process rather than as the definitive set of national transportation system indicators. A second part of the NTS analytical process involves the development and application of a national transportation network analysis capability (NTNAC) that will provide the ability to evaluate the national network in a multi- modal manner. Using the NTNAC, problems with the Nation's transportation system can be identified and policy options to address these problems evaluated. The report concludes with a discussion of the use of the NTS within the Department. It is proposed that the results of the analyses carried out using the national transportation performance measures and the NTNAC in the assessment of the Nation's transportation system, the identification of issues, and the analysis of options be presented in biennial State of the National Transportation System reports.
The purpose of this synthesis was to document the past and current experiences of public transit agencies that have planned, implemented, and operated fare-free transit systems. The report concentrates on public transit agencies that are either direct recipients or sub-recipients of federal transit grants and provide fare-free service to everyone in their service area on every mode they provide. The report will be of interest to transit managers and staffs, small urban and rural areas, university, and resort communities, as well as stakeholders and policy makers at all levels who would be interested in knowing the social benefits and macro impacts of providing affordable mobility through fare-free public transit. A review of the relevant literature was conducted for this effort. Reports provide statistics on changes in levels of ridership associated with fare-free service. White papers or agency reports identified by the topic panel or discovered through interviews with fare-free transit managers were also reviewed. Through topic panel input, Internet searches, listserv communications, and APTA and TRB sources, the first comprehensive listing of public transit agencies that provide fare-free service in the United States was identified. A selected survey of these identified public transit agencies yielded an 82% response rate (32/39). The report offers a look at policy and administrative issues through survey responses. Five case studies, achieved through interviews, represent the three types of communities that were found to be most likely to adopt a fare-free policy: rural and small urban, university dominated, and resort communities.
This report describes many ways in which science and engineering can contribute to making the nation safer against the threat of catastrophic terrorism. The report identifies key actions that can be undertaken now, based on knowledge and technologies in hand, and, equally important, describes key opportunities for reducing current and future risks through longer-term research and development activities.
"Proposes experiments in deregulating and privatizing the country's transportation systems to rid them of inefficiencies and significantly improve their performance in moving goods and people around the United States; the book covers roads, airports and airport traffic control, mass transit, intercity buses and railway networks"--Provided by publisher.
Mobility is fundamental to economic and social activities such as commuting, manufacturing, or supplying energy. Each movement has an origin, a potential set of intermediate locations, a destination, and a nature which is linked with geographical attributes. Transport systems composed of infrastructures, modes and terminals are so embedded in the socio-economic life of individuals, institutions and corporations that they are often invisible to the consumer. This is paradoxical as the perceived invisibility of transportation is derived from its efficiency. Understanding how mobility is linked with geography is main the purpose of this book. The third edition of The Geography of Transport Systems has been revised and updated to provide an overview of the spatial aspects of transportation. This text provides greater discussion of security, energy, green logistics, as well as new and updated case studies, a revised content structure, and new figures. Each chapter covers a specific conceptual dimension including networks, modes, terminals, freight transportation, urban transportation and environmental impacts. A final chapter contains core methodologies linked with transport geography such as accessibility, spatial interactions, graph theory and Geographic Information Systems for transportation (GIS-T). This book provides a comprehensive and accessible introduction to the field, with a broad overview of its concepts, methods, and areas of application. The accompanying website for this text contains a useful additional material, including digital maps, PowerPoint slides, databases, and links to further reading and websites. The website can be accessed at: http://people.hofstra.edu/geotrans This text is an essential resource for undergraduates studying transport geography, as well as those interest in economic and urban geography, transport planning and engineering.
