Long-Term Effectiveness of Radar Speed Feedback Signs for Speed Management

This article discusses a longitudinal analysis of posted speed limit compliance over a five-year period. The speeds of mixed traffic were measured for various corridors in Campbell, California. The hypothesis of the study is that radar signs do not maintain their effectiveness over time. The results indicate that continuous use of radar speed feedback signs provides prolonged speed management where applied. The use of radar speed feedback signs resulted in mean speed changes that were statistically significant five years after sign deployment.
