Safety Enhancements  to Reduce Speeding in School Zones Using Driving Simulation

Traffic crashes in school zones continues to be a serious safety concern. Low speed compliance in school zones is a pressing issue that compromises vulnerable road-users creating the possibility of high impact crashes. Four countermeasures designed to reduce speeding in a school zones were evaluated to measure changes in drivers’ speed using a driving simulator. The countermeasures evaluated were Overhead signs, Two-Step Speed Reduction, Reduce Speed Ahead signs, and Speed Monitoring Display. Performance was measured using speed, and speed compliance as dependent variables. Results indicate that all the countermeasures evaluated improved drivers’ compliance with the School Zone speed Limits. Similar improvements were observed with both the overhead signs and the Two-Step Speed Reduction. However, the best results were obtained with the Speed Monitoring Display used as an Advanced Driver Assistance System (ADAS). All the improvements were statistically significant with respect to the base case considering the current signage conditions. Furthermore, the analysis performed demonstrated improving compliance through the combination of overhead signs with the other countermeasures evaluated
