                Safety Evaluations of Innovative Intersection Designs for Pedestrians and Bicyclists

              Abstract:The research documented in this report was conducted as part of the Federal Highway Administration’s (FHWA’s) Evaluation of Low-Cost Safety Improvements Pooled Fund Study (ELCSI-PFS). The objective of this FHWA project was to investigate the operational and safety improvements of innovative intersection retrofitting designs that benefit pedestrians and bicyclists, while maintaining a reasonable service to motor vehicles. These designs are also called protected intersections, and that is the term used in this document. Traffic professionals are exploring protected intersections to determine if they can successfully accommodate multimodal transportation by reducing conflicts between moving vehicles and vulnerable users (VU) or by lowering the impact force (reducing the vehicle speed and changing the collision angle in the event of a collision). The project summarizes previous research efforts, develops three design types, identifies potential study sites (both before-after and comparison-existing pairs), and collects in-field operational behaviors of the users. This report details the method and results of this study.
