摘要

无信号交叉口被确定为关键位置,因为这些位置发生的车祸数量更高。在无信号交叉口发生车祸的主要原因是视距有限、驾驶员在次要道路上对间隙的错误评估以及车辆在主要道路上的较高速度。为了提高安全性并降低无信号交叉口撞车事故的严重程度,开发了一种称为交叉口冲突预警系统(ICWS)的智能交通系统(ITS)。ICWS由一个激活的警告标志和检测接近十字路口的车辆的传感器组成。本文旨在总结已发表在文献中的ICWS的性能评估。审查首先概述了在无信号交叉口设计和安装ICWS的目的。然后讨论了在现实世界、驾驶模拟器和模拟三种不同环境中评估ICWS有效性所考虑的驾驶性能指标,并给出了其结果。本文还讨论了用于检测接近十字路口的车辆的传感器类型及其在车辆检测中的准确性。结果表明,ICWS显著改善了驾驶员的行为。在ICWS存在的情况下,驾驶员的反应时间更短,接近速度更低,临界间隙接受度增加,冲突减少。通过对驾驶员进行标志教育,保持系统可靠性,并进一步检查各种交通因素、驾驶员因素和环境因素对ICWS的影响,可以提高ICWS的性能。这项研究的发现可以帮助研究人员和工程师设计更好的ICWS,大大提高无信号交叉口的驾驶性能和安全性。

Evaluation of intersection conflict warning system at unsignalized intersections: A review

Unsignalized intersections are identified as the critical locations due to higher number of road crashes at these locations. The primary causes of crashes at unsignalized intersections are limited sight distance, incorrect assessment of gaps by drivers on the minor road, and higher speeds of vehicles on the major road. In an effort to improve safety and reduce the severity of crashes at unsignalized intersections, an intelligent transportation system (ITS) called the intersection conflict warning system (ICWS) has been developed. The ICWS consists of an activated warning sign and sensors that detect vehicles approaching the intersection. This paper aims to summarize the performance evaluation of ICWS that has been published in the literature. The review commences with an overview of the purpose of designing and installing ICWS at unsignalized intersections. It then discusses driving performance measures considered to evaluate the effectiveness of ICWS in three different environments, i.e., real world, driving simulator, and simulations, and their results are presented. The paper also discusses the type of sensors used to detect vehicles approaching the intersection and their accuracy in vehicle detection. The results reveal that ICWS had substantially improved driver behaviour. In the presence of ICWS, drivers resulted in shorter reaction time, lower approach speed, increased critical gap acceptance, and reduction in conflicts. An improvement in the performance of ICWS can be achieved by educating drivers about the sign, maintaining system reliability, and further examining the effect of various traffic factors, driver factors, and environmental factors on ICWS. The findings of this study can help researchers and engineers to design a better ICWS that can greatly enhance driving performance and safety at unsignalized intersections.
