基于Ex⁃TPB的驾驶人隧道内换道行为影响因素分析

Analysis of influencing factors on driver lane⁃changing behavior in tunnel based on Ex⁃TPB

为了探究和预测驾驶人在隧道内的不安全换道行为,在计划行为理论的基础上引入驾驶习惯解释变量,构建了基于扩展计划行为理论的驾驶人隧道内换道行为的结构方程模型.基于321份问卷数据对结构方程模型的有效性进行了分析,并从心理学角度对驾驶人隧道内换道行为的心理影响因素以及各因素之间的相关关系进行分析.结果表明:该模型对分析驾驶人隧道内换道行为有良好的解释力;驾驶习惯、换道行为意向和知觉行为控制对换道行为有显著正向影响;驾驶习惯、行为态度和知觉行为控制对换道行为意向存在显著正向影响,主观规范对换道行为意向存在显著负向影响.

To explore and predict the unsafe lane⁃changing behavior of drivers in tunnels,a structural equation model of lane⁃changing behavior of drivers in tunnels was established based on the extended theory of planned behavior(Ex⁃TPB)by introducing driving habit explanatory variables on the theory of planned behavior.A questionnaire survey was conducted among drivers.Based on 321 questionnaires data,the effectiveness of the structural equation model was analyzed,and from psychology,the psychological factors on driver lane⁃changing behavior and the relationship among various factors were analyzed.The results show that the structural equation model is suitable for analyzing the lane⁃changing behavior of drivers in tunnels.Driving habits,lane⁃changing behavior intention and perceived behavior control have direct positive and significant effects on lane⁃changing behavior.Driving habits,behavioral attitudes and perceived behavioral control have significantly positive effects on lane⁃changing behavior intention,while subjective norms have significantly negative effects on lane⁃changing behavior intention.
