Evaluation of Effects Associated with Advanced Vehicle Detection Systems on Dilemma-Zone Protection
Vehicle detection has the potential to improve how drivers interact with change intervals to minimize the potential hazards associated with dilemma zones at signalized intersections. The dilemma zone described extensively throughout the literature refers to the area where drivers experience difficulty with stop/go decision making when presented a circular yellow indication. Incorrect decisions lead to increased rear end crashes and more severe angle crashes. To evaluate the potential for a particular configuration of point and space sensors to mitigate the influence of dilemma zones on safety, observations were made at a high-speed signalized intersection providing advanced vehicle detection under both conditions. Results showed that space sensors can reduce dilemma zone incursions and shift drivers downstream of the dilemma zone where the stop/go decision is more easily determined.
