Red-light running (RLR) behavior is one of the riskiest behaviors at signalized intersections and is becoming a prominent cause of intersection-related crashes (P. Chen et al., 2017). According to the report published by AAA Foundation for Traffic Safety, during 2019 more than two people were killed every day due to noncompliance with red signal indications (AAA Foundation for Traffic Safety, 2020). The City of Phoenix has teamed up with the University of Arizona (UArizona) to draft a comprehensive literature review on the factors influencing RLR violation (such as yellow light interval, clearance time), and identify potential solutions and countermeasures (such as photo enforcement cameras, modifying yellow/clearance time).
