A two-year pilot study evaluating the combined use of two red light running treatments, red light cameras and stepped-up police enforcement, has recently been completed in the province of Ontario. Collision and volume data representing forty-eight different study sites distributed among six participating municipalities was analysed for a five-year before period and a two-year after period using the Empirical Bayes method. The estimated number of collisions occurring at the study sites was compared to the actual observed number of collisions that occurred to determine the safety effectiveness of the two treatments. The results indicate that fatal and injury collisions decreased 6.8 percent while property damage only collisions increased 18.5 percent at the study sites. These results show that the treatments have had an encouraging safety results as they have reduced the number of severe collisions from occurring at the study sites. A decrease in the number of angle collisions was also found, however this was offset by an increase in rear-end collisions.
