Methods of Increasing Pedestrian Safety at Right-Turn-On-Red Intersections (User's Manual)

Source: Federal Highway Administration (FHWA)

This study sought to determine current motorist compliance to RTOR regulations, develop and test countermeasures for RTOR pedestrian crashes, and develop improved guidelines for prohibition of RTOR. Based on data from several US cities, only 3.7 percent of all right turning drivers violate NO TURN ON RED (NTOR) signs. However, of drivers with an opportunity to turn right on red, 20 percent violated the sign. At locations with RTOR allowed, 56.9 percent of motorists do not come to a complete stop before turning right on red.

Based on conflict and violation data, 30 countermeasures were developed as possible treatments for RTOR-pedestrian crashes. Seven of these were field tested, including an offset stop bar, a red ball (symbolic) NTOR sign, a larger 30X36-in (75X90-cm) NTOR sign, a LOOK FOR TURNING VEHICLES pavement marking, a NTOR WHEN PEDESTRIANS ARE PRESENT sign, and an electronic variable message (blank-out) NTOR sign. Several promising applications for the devices were recommended. A critique was made of the current MUTCD guidelines on RTOR prohibition. Based on an analysis of conflicts at 199 intersection approaches, improved guidelines were recommended.

The final report consists of two volumes. Volume I is the Executive Summary and Volume II is the Research Report (available at ). This User's Manual was prepared to provide guidance to highway agency officials on techniques to improve pedestrian and motorist safety with respect to RTOR.
