Abstract
PROBLEM: This study investigates the effect of the French Automated Speed Enforcement Program (ASEP) on casualties involving different types of road users. METHOD: Interrupted time-series analyses were conducted to estimate the effect of the ASEP. RESULTS: Overall, the ASEP was associated with a decrease of 19.7% in traffic fatalities and crashes with injuries. Significant diminutions were observed for passenger vehicles/light SUVs (−25.4%), motorcyclists (−39.0%), and trucks (−15.7%). Adding red light cameras and devices taking pictures of both ends of the vehicle produced, in some cases, additional gains among specific categories of road users. CONCLUSION: Traffic fatalities, crashes with injuries and the severity of crashes significantly declined following the introduction of the ASEP in November 2003. Practical applications: ASEPs are an effective strategy to prevent traffic casualties. Innovations such as red light cameras and devices taking pictures of both ends of the vehicle can improve an ASEP.
