Best Practices for Installation of Rectangular Rapid Flash Beacons (RRFB) With and Without Median Refuge Islands

This research will seek to produce the guidance that practitioners need about the placement of Rectangular Rapid Flash Beacons (RRFB) beacons in combination with median refuges on three lane roadways. This research will provide empirical evidence about the effect of refuge medians on driver yielding and pedestrian crossing behavior. The research will also compare the effect of median-mounted RRFB displays versus far side-mounted RRFB displays with respect to these same performance measures. Finally, this project will enhance and reanalyze the SPR 778 RRFB data to produce more robust estimates of the safety effectiveness. With these measures well-quantified, Oregon Department of Transportation (ODOT) will be able to improve the guidance for pedestrian crossing enhancements.
