Abstract:

Several methods have been used to emphasize the presence of a pedestrian crossing, including one that supplements signage with beacons or embedded LEDs. Rapidly flashing beacons constitute one type of treatment used at midblock pedestrian crossings to bring drivers’ attention to a crossing pedestrian. This study evaluated the effect of the activation of the beacon and traffic volumes on driver yielding behavior when a crossing pedestrian was present. Rectangular rapid-flashing beacons (RRFBs) and circular rapid-flashing beacons (CRFBs) were installed at 12 sites in four cities. At approximately half of the study sites, RRFBs were initially installed and later replaced with CRFBs. At the other study sites, CRFBs were initially installed and later replaced with RRFBs. The same flash pattern was used for both beacon shapes. Driver yielding rates were compared between pedestrian crossings when a beacon was activated and when it was not. The results of the analysis showed that when a beacon, whether rectangular or circular, was activated, a driver was 3.68 times more likely to yield to pedestrians than when the beacon was not activated. The results of an analysis of the relationship between traffic volume and driver yielding indicated that driver yielding behavior was not influenced by traffic volume at the study sites.
