Abstract

The objective of the work under Phase III of the contract for Project 17-26, as presented in this report, is to develop a methodology for quantifying the pedestrian safety effects related to existing site characteristics and/or proposed improvements on urban and suburban arterials. The scope of this new work is similar to the scope of the work in Phases I and II of Project 17-26, except that the new work specifically addresses pedestrian safety. The pedestrian safety prediction methodology has been developed to function as part of the overall safety prediction methodology for urban and suburban arterials being developed in Project 17-26. Thus, the comprehensive methodology will combine predicted values for nonpedestrian crashes based on the methodology developed in Phases I and II of Project 17-26 and predicted values for pedestrian crashes based on the methodology presented in this report. The scope of the Phase III pedestrian safety methodology includes signalized intersections and roadway segments between intersections, but does not include unsignalized intersections. Pedestrian safety at unsignalized intersections will be addressed with the methodology developed in Phases I and II. The end product of the Phase III work will be prepared in a form compatible with the urban and suburban arterial safety prediction methodology and appropriate for incorporation in the Highway Safety Manual.
