An innovative detection–control system was developed for the Texas Department of Transportation to reduce both delay and crash frequency at rural intersections. This system was implemented at several intersections in Texas, and its safety and operational benefits were evaluated. This report documents findings and conclusions reached after a 3-year implementation project. The detection–control system was installed and evaluated at each of five intersections in Texas during the 3-year period. Evaluation of before-and-after data indicates that the new detection– control system was able to reduce approach delay by 14%, stop frequency by 9%, red light violations by 58%, heavy-vehicle red light violations by 80%, and severe crash frequency by 39%.
