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