Innovative Operational Safety Improvements at Unsignalized Intersections

This research is aimed at identifying innovative methods of improving safety at unsignalized intersection locations on high-speed, multi-lane roadways. Unsignalized intersections have a vast number of possible geometric and environmental configurations. No one treatment will be able to resolve all possible safety problems and in fact safety issues could potentially arise at intersections that meet all of the relevant design ‘standards’. Therefore, a broad range of innovative treatments are identified in this report to stimulate ideas for improving problem locations.
