摘要在城市交叉口的混合交通中，行人作为交通参与者中的弱势群体，在交通冲突中很容易受到伤害。我国大部分城市的信号交叉口中，右转机动车不受信号控制，右转机动车与过街行人的冲突十分常见。本文的研究内容是信号交叉口右转机动车与过街行人的冲突特性。在大量阅读和了解国内外关于交通冲突安全评价方法的基础上，选择交通冲突技术作为人-车冲突分级的判定方法。通过对信号交叉口人-车冲突特性的分析，了解右转机动车与行人冲突的特点。利用视频采集法获得大量的交通流数据，通过对视频数据的统计整理，分析人-车冲突时行人和右转机动车的运动状态。选择速度作为判定标准，运用临界间隙法确定冲突分级的临界值，对人-车冲突程度进行判定。将交叉口的各冲突点划分为4个冲突区，运用灰色聚类评价模型对其安全性进行评价，并结合交叉口实际情况进行分析，检验模型的有效性和适用性。87477

Title REASEARCH ON TRAFFIC CONFLICT CHARACTERISTICS  BETWEEN PEDESTRIAN AND RIGHT-TURNING VEHICLE IN SIGNALIZED INTERSECTION 

Abstract In the mixed traffic of urban intersection,pedestrians,as the vulnerable groups of traffic participants,are vulnerable to the traffic conflict。In most of our urban signal intersection,the right turning vehicle is not under the control of the signal,conflict of right turn vehicles and pedestrians to cross the street is very common。The research content of this paper is the conflict characteristics of signalized intersection right turn vehicles and pedestrians to cross the street。On the basis of a large number of domestic and foreign security evaluation methods about traffic conflict,traffic conflict technology is chosen as the decision method of human vehicle collision classification。To understand the characteristics of right turn motor vehicle and pedestrian conflict by analyzing the characteristics of human vehicle collision at the intersection。Using video capture method to obtain a large number of traffic flow data,through the statistical analysis of the video data to analyze the movement of pedestrians and right turn motor vehicles in the conflict between people and vehicles。Choosing the speed as the criterion,the critical value of conflict classification is determined by the critical clearance method which is used to determine the degree of human vehicle collision。The conflict points of intersection are pided into 4 conflict zones,using grey clustering evaluation model to evaluate the security of the model and the validity and applicability of the model were analyzed with the actual situation of intersection。

Keywords: signalized intersection,right-turning vehicle,pedestrian,traffic conflict,grey clustering evaluation
