Pedestrian Signal Safety

for Older Persons This study had two primary objectives: 1) to provide the supporting research to assist traffic engineers in understanding the walking characteristics of older pedestrians and 2) to provide more information on the extent to which various intersection operational conditions might be able to tolerate additional time for the pedestrian interval without sacrificing substantial efficiencies (and, conversely, the identification of intersection operational conditions that would provide significant degradation in the movement of vehicles).
