Abstract

There is a growing need for quantitative traffic-estimating tools to improve pedestrian transportation safety, access, and mobility. A sketch-plan method is introduced to estimate peak-hour pedestrian trips for crossings at intersections (node) and parallel sidewalk-midblock (link) locations. This tool integrates pedestrian travel into routine trip-estimating by applying standard traffic data to quantify pedestrian trips. The method presented is based on access-egress mode trip generation and applies peak vehicle-per-hour turning movements, transit vehicle or passenger counts, and walk and bike counts or projections to produce total peak pedestrian-per-hour (pph) trips. A previous method used trip rates based on land use to generate pph trips. However, that model is 20 years old, requires detailed land use data, and does not distribute and assign pedestrian trips. The following sketch-plan method was developed in a case-study of a suburban growth corridor in Plattsburgh, New York. Sample applications of pedestrian trip-generation estimates are presented to illustrate how pedestrian travel-demand projections, in addition to vehicular traffic forecasting, can support the adoption of balanced facility treatments to meet the mobility and safety needs of all modes of transportation.
