Bicycling and walking make up a relatively small portion of commuting activity in the United States, but these nonmotorized travel modes play important roles within many of the nations local transportation systems. Infrastructure that supports bicycling and walking expands transportation options and may complement other forms of transportation by supplementing segments of trips. Several state and local agencies have taken steps to promote pedestrian and bicycle travel. Strategies to accommodate nonmotorized travel vary across communities, but may include sidewalk modifications, pedestrian-oriented commercial centers, or bicycle lanes to name a few. In recent years, the number of cities with bicycle sharing programs has increased considerably. |
