困境区域引起的无意闯红灯违规分析

Analysis of Inadvertent Red Light Running Violation Owing to Dilemma Zone

本文分析了车辆在交叉口由于车辆的行驶速度较高或野蛮驾驶造成的闯红灯行为,其中除了应当给予惩处的驾驶员的故意行为以外,也包括无意闯红灯行为。无意闯红灯的原因和特点同城市交叉口的宽度、理想速度、车辆动力学特点、交通信号灯的黄灯间隔时间以及困境区域有关。本文给出了由困境区域引起的无意闯红灯违规的数学描述, 建立了用于城市道路交叉口闯红灯违规的模型,利用该模型对西安部分地区的数据进行仿真和评价。

This paper analyzed the red light nmning behavior happens at urban intersections caused by high approach speeds coupled with aggressive driving. It includes inadvertently red light running that is easy to amuse the sympathy of traffic managers other than advertently behavior of driver that should be punished. The reason and characteristic of inadvertently red light running is related with the width of urban intersection, idea speed, vehicle dynamics nature, yellow interval of signal and dilemma zone. A narrative description and mathematical derivation of inadvertent red light running violation owing to dilemma zone are presented. Models suitable for red light nmning at urban intersections are established. The model has been calibrated and tested with data from local area of Xi＇ an, China.
