DETECTION-CONTROL SYSTEM FOR IMPROVING THE SAFETY AND OPERATION OF ISOLATED HIGH-SPEED INTERSECTIONS

High-speed signalized intersections have both safety and efficiency problems. This paper, from a set of conference proceedings on Intersection Safety: Achieving Solutions Through Partnerships (March 2004, Irvine, California), outlines a new approach to high-speed intersection control. The authors describe a dynamic dilemma zone allocation system that uses measured vehicle speeds with a control algorithm to decide when to end the signal phases. This Detection-Control system (D-CS) is similar to a multiple advance detector system in that it uses information from detectors located upstream from the intersection to extend the green. However, D-CS employs a computerized algorithm that uses vehicle speed and length information to predict when each vehicle arrives in its dilemma zone, and to provide additional protection for trucks. The authors report on simulation and field evaluations of the new system. In both settings, the new system showed that it could improve safety and maintain efficient operations at high-speed intersections.
