Guidance to Improve Pedestrian and Bicycle Safety at Intersections

The objective of this research is to develop guidance for transportation practitioners to improve pedestrian and bicycle safety at intersections through design and operational treatments that (1) identifies and evaluates current practices, and emerging technologies and trends, in the U.S. and internationally; (2) describes current best practices for measuring the effectiveness of such intersection treatments; (3) evaluates safety outcomes of specific intersection treatments using quantitative measures; and (4) identifies and ranks strategies, processes, and relationships that could accelerate the adoption of improved pedestrian and bicycle intersection design and operational treatments. The approaches to evaluate pedestrian and bicycle treatments can be separate, but implementation of the treatments should be coordinated. The guidance should address a broad range of issues related to improved pedestrian and bicycle safety at intersections such as, but not limited to the following: (1) Identifying typical and innovative design treatments to improve the safety of pedestrians and bicyclists at intersections (e.g., signalized, unsignalized, midblock crossings, roundabouts, ramps); (2) Identifying common motor vehicle/pedestrian, motor vehicle/bicyclist crash types and severity at intersections; (3) Identifying differences in temporal or spatial settings (e.g., urban, suburban, rural, land use); (4) Developing quantitative safety analysis techniques for evaluating design and operational treatments (e.g., conflict studies, crash analysis, injury severity, behavioral analysis, naturalistic driving studies): -- Considering specific bike design and operational elements (e.g., bike boxes, cycle tracks, separated bike lanes, colored pavement, bicycle signals); -- Considering specific pedestrian design and operational elements (e.g., refuge islands, curb extensions, signals, prohibited right turn on red, road diets, traffic calming, signal operations); (5) Documenting benefits and trade-offs of pedestrian and bicycle intersection design versus operational treatments; (6) Suggesting countermeasures and criteria for implementation; and (7) Providing a foundation for future data collection and more rigorous studies that produce Crash Modification Factors (CMFs). While the guidance should be directly applicable to most situations, it should also outline decision-making processes and criteria that would assist agencies in identifying flexible solutions.
