Abstract

Pedestrian characteristics and physical elements instrumental in shaping walking activity are used to develop a systematic analysis of pedestrian travel. The methodology provides a generalized supply-demand conceptualization of the problem based on pedestrian needs and accommodations (or impedances) and derives a strategy to show that the frequency of walking trips is related to the quality of the walking environment. Trip characteristics define the needs of various socioeconomic pedestrian types. The influential elements of the walking system are stated in terms of accommodations, such as overpasses, pedestrian tunnels, or lighting along walkways, and of impedances arising from high traffic volumes or the barriers posed by the roadways themselves. Trade-off effects between these two major factors establish an index of the quality of the walking environment. Procedures for gathering field data to quantify pedestrian needs and accommodations are proposed, and graphical means of using the information to measure the impact of transportation projects on pedestrian mobility are illustrated. Specific data sought are attitudinal survey information on walking incentives and quantitative quantitative measurements of walking accommodations. It is envisioned that the systematic procedures proposed can be incorporated into the highway planning process to improve pedestrian conditions.
