• Abstract:
  The Federal Highway Administration (FHWA) organized a pooled fund study of 40 States to evaluate low-cost safety strategies as part of its strategic highway safety effort. The purpose of the FHWA Evaluation of Low-Cost Safety Improvements Pooled Fund Study is to evaluate the safety effectiveness of high-priority, low-cost safety strategies through scientifically rigorous, crash-based studies. One of the strategies selected for evaluation was the installation of pedestrian countdown signals (PCSs). The intent of this strategy is to reduce the frequency of pedestrian crashes, which tend to be high-profile and very severe. The objective of the study was to estimate the safety effectiveness of the PCS strategy as measured by crash frequency. The study objective noted that changes in pedestrian signals could change driver behavior and affect not just pedestrian crashes but also the propensity for rear-end and angle crashes. In addition to determining the overall safety effect of the treatment, a further objective was to address whether the safety effect was different depending on the type of intersection (i.e., three-leg versus four-leg signalized intersections).
