“…Predict the time-varying stop queues: This function is to predict the queue length using traffic information from both system sensors and signal states from the traffic controller. Estimate the probability of an observed vehicle taking the ''pass'' action during a yellow phase: This module, the core of the DZPS, can track each individual vehicle's trajectory within the detection area, and estimate a vehicle's pass/stop probability during a yellow phase to determine the activation of an all-red extension (18).…”

“…The optimal tradeoff between the detection and false-alarm rates can be investigated theoretically. Abadi et al found that all-red extension calls between different thresholds of system accuracy had little effect on traffic delays ( 18 ). Considering the potential cost of a red-light-running vehicle causing a right-angle crash compared with unnecessary delays to traffic flow due to some false alarms, the detection rate of 100% was set as the foremost objective of the deployed DZPS.…”

“…An example of such designs is the all-red extension, which can provide an extended all-red phase to accommodate vehicles failing to perform a stop at the intersection ( 14 , 15 ). Evaluation of the effectiveness of such an all-red extension method can also be found in the literature ( 16 – 18 ).…”

Despite the fact that both traffic researchers and highway agencies have devoted considerable efforts over the past few decades to improving intersection safety, development of effective strategies to contend with this vital issue remains a challenging task. This research presents the field evaluation results of a Dilemma Zone Protection System (DZPS) implemented at two hazardous intersections in Maryland, U.S.A. The deployed DZPS can offer both proactive and reactive protections to drivers approaching a signalized intersection during a yellow phase. Field evaluations conducted at two intersections with DZPS deployed confirmed a 100% detection rate for red-light-running vehicles, timely activation of the all-red extension to prevent right-angle crashes, and effectively discouraging drivers from taking aggressive “pass” decisions during the yellow or all-red phases. The potential extension of the DZPS for speed harmonization on arterial traffic flows is also discussed.

With the advancement of implementation for a novel traffic control device, the Flashing Yellow Arrow (FYA), agencies across the country have continually sought strategies to improve intersection operations and safety, specifically with respect to the left-turn application. More so, permissive left-turn intervals have been communicated to drivers using several traffic signal indications; however, most frequently these phases are represented through the circular green (CG) ball and more recently, the FYA. Previous research in this area determined that the FYA indication produced the most effective communication of permissive left-turns. Further, this previous research led to the inclusion of the FYA in the 2009 edition of the Manual on Uniform Traffic Control Devices (MUTCD). In recent years, agencies across the country have embraced the implementation of the FYA for permissive left-turns. However, there remains a lack of national guidance on the definition of change and clearance intervals for transitioning between protected and permissive left-turns. Complicating the matter is the connection between traditional signal phasing/design and human factors. Investigation through driver comprehension and real-world operations will allow us to not only evaluate current conditions, but also experimental and future conditions. Recommendations provided from this research will ultimately offer agencies with the strategies for the most effective transition from a protected left-turn to a permissive left-turn phase. v
