A Workable Solution for Reducing the Large Number of Vehicle and Pedestrian Accidents Occurring on a yellow light

Journal of Transportation Technologies 2024年第1期14卷 82-87页

作者： Pranav Gupta Silki Arora Drive Safe Now Ottawa Canada

Traffic intersections are incredibly dangerous for drivers and pedestrians. Statistics from both Canada and the U.S. show a high number of fatalities and serious injuries related to crashes at intersections. In Canada, during 2019, the National Collision Database shows that 28% of traffic fatalities and 42% of serious injuries occurred at intersections. Likewise, the U.S. National Highway Traffic Administration (NHTSA) found that about 40% of the estimated 5,811,000 accidents in the U.S. during the year studied were intersection-related crashes. In fact, a major survey by the car insurance industry found that nearly 85% of drivers could not identify the correct action to take when approaching a yellow traffic light at an intersection. One major reason for these accidents is the “yellow light dilemma,” the ambiguous situation where a driver should stop or proceed forward when unexpectedly faced with a yellow light. This situation is even further exacerbated by the tendency of aggressive drivers to inappropriately speed up on the yellow just to get through the traffic light. A survey of Canadian drivers conducted by the Traffic Injury Research Foundation found that 9% of drivers admitted to speeding up to get through a traffic light. Another reason for these accidents is the increased danger of making a left-hand turn on yellow. According to the National Highway Traffic Safety Association (NHTSA), left turns occur in approximately 22.2% of collisions—as opposed to just 1.2% for right turns. Moreover, a study by CNN found left turns are three times as likely to kill pedestrians than right turns. The reason left turns are so much more likely to cause an accident is because they take a driver against traffic and in the path of oncoming cars. Additionally, most of these left turns occur at the driver’s discretion—as opposed to the distressingly brief left-hand arrow at busy intersections. Drive Safe Now proposes a workable solution for reducing the number of accidents occ

yellow light dilemma zone researches: a review

引用

Journal of Traffic and Transportation Engineering(English Edition) 2014年第5期1卷 338-352页

作者： Yaping Zhang Chuanyun Fu Liwei Hu School of Transportation Science and Engineering Harbin Institute of Technology Faculty of Transportation Engineering Kunming University of Science and Technology

The yellow light dilemma zone is widely known as an area on the high-speed intersection ap- proach, where vehicles neither safely stop before the stop line nor proceed through the intersection dur- ing amber interval. Within such an area, a vehicle might be involved in a right-angle crash or rear-end collision. This issue has been extensively discussed over five decades in traffic engineering field, cov- eting from theory to practice. However, few comprehensive review literatures on the amber signal di- lemma zone problems can be found. The objective of this paper is to summarize the evolution of yellow light dilemma zone researches. Basic definition and boundary of dilemma zone followed by driver be- havior and dilemma zone hazard measurement are depicted. At last, the future directions of yellow light dilemma zone research are discussed.
