基于结构方程的信号交叉口驾驶人两难区选择行为影响因素分析

Effect Factors Analyzing on the Driver Choices Behavior on the Dilemma Zone at the Signalized Intersections Based on Structural Equation Model

驾驶人在信号交叉口两难区的驾驶选择行为影响因素分析对交叉口的安全运行具有重要意义。通过设计问卷,获取了不同个人属性、不同道路情况、考虑设置辅助驾驶系统等因素下驾驶人的选择行为,使用结构方程分析了上述因素对驾驶人在两难区的选择行为的影响。结果表明:驾驶人的个人属性、驾驶信息、对于辅助系统的态度及意见等都对驾驶人在两难区的选择行为有直接的影响,而其中驾驶人的驾驶信息是主要影响因素。

The driving choice behavior factors analyzing on the dilemma zone has important meaning for the safe operation at the signalized intersection.The driver s choice behavior has been analyzed using the structural equation model(SEM)through the questionnaire,considering the factors of different personal attributes,different road conditions,considering the setting of auxiliary driving system and other factors.The results show that the driver s information,the attitude and opinion of the auxiliary system have a direct influence on the driver s choice behavior in the dilemma area,and the driver s information are the main factors.
