Book excerpt: This Innovations Deserving Exploratory Analysis project improved and evaluated a detection-control system (D-CS) for enhanced traffic safety at high speed signalized intersections. A literature review was conducted to identify potential enhancements to the D-CS control algorithm required to create the "second generation" D-CS algorithm. The needed enhancements included dilemma zone protection based on vehicle size, real-time dilemma zone changes, coordination, and real-time measures of effectiveness reporting. After selecting the most feasible enhancements, the control algorithm was modified and tested in the laboratory. Based on laboratory test results and refinements, a "second generation" D-CS control algorithm was developed capable of providing dilemma zone protection specific to vehicle type using a modified system to prevent max out during "Stage 2" operation.
