Bicycling and Walking in the United States 2012 Benchmarking Report.

摘要

This report focuses on 50 states and the 51 largest U.S. cities. Most bicycling and walking is in urban areas, and because of short trip distances, the most potential for increasing bicycling and walking is in cities. Whenever possible, the Alliance collected data for this report directly from uniform government data sources. Researchers collected data that were not readily accessible from national sources through two surveys for cities and states.
