Abstract

The purpose of this study was to develop and evaluate innovative pedestrian sign and signal alternatives, particularly those that indicate the clearance interval (in place of the flashing DONT WALK message) and those that warn pedestrians of possible turning vehicles (instead of the flashing WALK message). A total of 41 alternatives were developed, and the 8 judged most promising were evaluated at several sites within 5 U.S. cities. The alternatives were evaluated using before-and-after studies of pedestrian violations and various types of pedestrian-vehicle conflicts. Based on the results of the Z-test analyses of observations at the study sites, several alternatives were recommended for inclusion in the Manual on Uniform Traffic Control Devices for application at intersections with pedestrian safety problems. These included the WALK WITH CARE signal indication, a sign for motorists stating YIELD TO PEDESTRIANS WHEN TURNING (regulatory sign), a pedestrian warning sign stating PEDESTRIANS WATCH FOR TURNING VEHICLES, and a pedestrian signal explanation sign (word and symbolic). A three-section pedestrian signal using DONT START to indicate the clearance interval was recommended for additional testing, but little or no benefit was found for the use of the steady DONT WALK indication for the clearance interval or the flashing WALK indication (to warn pedestrians of turning vehicles).
