STUCTURING AN 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. The influential elements of the walking system are stated in terms of overpasses, pedestrian tunnels, or lighting along walkways, and of impedances arising from high traffic volumes or the barriers posed by the roadways.
