Design and Implementation of a Detection, Control, and Warning System (DCWS) for Dilemma Zone Applications

This paper presents evaluation results for an intelligent dilemma zone protection system that integrates advanced warning signs with all-red extension strategies to reduce the number of red-light running vehicles and to provide extra time to clear the intersection. To reflect drivers’ response to the yellow phase, a behavioral model was developed and calibrated with field data from six intersections. The calibrated behavioral model was incorporated in VISSIM to generate the simulation platform for experimental analysis. The study conducted extensive simulation experiments and compared the proposed system’s performance with other two designs based on the number of red-light runners and remaining all-red time for those running on red. Results indicate that the proposed system offers the best protection on safety measures. Sensitivity analyses have also been conducted to assess the impact on the number of red-light running vehicles if different locations are selected for the advanced warning sign and under the different traffic volume
