Book excerpt: Bicycling and walking can play an increasingly significant role in a balanced intermodal transportation system. The Intermodal Surface Transportation Efficiency Act of 1991 (ISTEA) recognizes the transportation value of bicycling and walking, and offers mechanisms to increase consideration of bicyclists' and pedestrians' needs within the National Intermodal Transportation System. This brochure summarizes these bicycle and pedestrian provisions under the ISTEA. The contents are organized as follows: Funding Sources - National Highway System (NHS) Funds, Surface Transportation Program (STP) Funds, Congestion Mitigation and Air Quality Improvement (CMAQ) Program Funds, Federal Lands Highway Funds, Scenic Byways Program Funds, and National Recreational Trails Fund; Planning Requirements; Additional Provisions - State Bicycle and Pedestrian Coordinators, Bridges, Section 402 Funding, and Federal Transit Funding; Federal/State Matching Requirements; and How the Federal-Aid Program Works.
