An Analysis of The Effects of Installing Pedestrian Countdown Timers on the Incidence of Pedestrian Crashes in the City of Detroit Michigan

In large cities, pedestrians account for 40% to 50% of traffic fatalities. Previous studies based on relatively small samples have concluded that Pedestrian Countdown Timers can reduce pedestrian crashes at signalized intersections. The purpose of the present study was to examine the effect of Pedestrian Countdown Timer (PCT) on crashes in a large city with a long baseline and relatively patterned introduction of PCTs. Like all treatments that target pedestrians, the installation of PCTs should be expected to produce the largest benefits in locations with very poor pedestrian safety compliance before installation.
