Performance of Dilemma Zone Mitigation System at Signalized Intersections

A high accident potential exists at high-speed signalized intersections where an area close to an intersection, called a dilemma zone (also known as decision zone). The potentially negative impact of dilemma zones on the operational capacity and safety of signalized intersections, has motivated a great deal of effort to the mitigation of the dilemma zone issue. This mitigation system have been pursued along the three complementary paths of signal timing, vehicle detection, and advanced warning.
