Does the Built Environment Influence Physical Activity?

TRB Special Report 282: Does the Built Environment Influence Physical Activity? Examining the Evidence reviews the broad trends affecting the relationships among physical activity, health, transportation, and land use; summarizes what is known about these relationships, including the strength and magnitude of any causal connections; examines implications for policy; and recommends priorities for future research.

Intermodal Transportation Education and Training

This conference was the fifth in a continuing series of conferences and workshops on intermodalism that have been organized by the Transportation Research Board (TRB) since the passage of the Intermodal Surface Transportation Efficiency Act of 1991 (ISTEA). The objective of the conference was to examine educational and training needs related to all aspects of intermodal transportation: technology, advanced logistics, information systems, planning, and management. Over a 3-day period, participants reviewed existing and developing transportation education programs across all disciplines and examined the roles of educational institutions, private industry, and government in setting an agenda for meeting intermodal transportation education and training needs. These proceedings contain the Chairman's summary, welcoming remarks, keynote address, case studies, status reports on current programs, and the response of a panel of distinguished transportation professionals to the conference findings.

System-specific Spare Bus Ratios

Documents critical site specific variables that influence transit agencies' spare bus ratio policies. It profiles a select group of transit agencies of varying sizes and geographic locations and describes their operating environments in order to relate how these affect the number of spare buses each agency needs to meet its service requirements.

Bus Use of Shoulders

This synthesis documents and summarizes transit agencies experiences with policies and regulations that permit buses to use shoulders on arterial roads or freeways to bypass congestion either as interim or long-term treatments. Both transit and highway perspectives are explored for jurisdictions that allow bus use of shoulders and those that have considered, but have not implemented, these treatments and the reasons why.

Modeling Mobile-Source Emissions

The Mobile Source Emissions Factor (MOBILE) model is a computer model developed by the U.S. Environmental Protection Agency (EPA) for estimating emissions from on-road motor vehicles. MOBILE is used in air-quality planning and regulation for estimating emissions of carbon monoxide (CO), volatile organic compounds (VOCs), and nitrogen oxides (NOx) and for predicting the effects of emissions-reduction programs.1 Because of its important role in air-quality management, the accuracy of MOBILE is critical. Possible consequences of inaccurately characterizing motor-vehicle emissions include the implementation of insufficient controls that endanger the environment and public health or the implement...

A Concept for a National Freight Data Program

Calls upon the Department of Transportation and its Bureau of Transportation Statistics to take the lead in coordinating freight data collection in the US. This work focuses on increasing the linkages between sources of data and filling data gaps to develop a source of timely and reliable data on freight flows. A national framework is needed.
