Federal transportation legislation, such as the Intermodal Surface Transportation Equity Act of 1991 (ISTEA) and the Transportation Equity Act for the 21st Century (TEA-21), has resulted in considerable public investments in bicycling and pedestrian infrastructure. The purpose of this study is to examine the distribution of these funds across geographic regions and to develop measures of successful implementation. Distributions of funds will be tracked by five federal transportation programs across states, regions, and areas defined by population density and demographic characteristics. A survey of state coordinators and reviews of websites and other reports will help identify features of state-level program designs that are associated with successful implementation. The findings of this study are meant to help inform policy discussions regarding the successful implementation of local and statewide investments in bike and pedestrian improvements.Health and Transportation Policy Forum: A resource for advocates, scientists, policy makers, and members of the general public who are interested in the intersections between transportation planning and health. The site provides information about research on the use of transportation policy-making to promote healthy communities.
