信号交叉口行人违章决策群体差异性分析

Group difference analysis of pedestrian violation decision at signalized intersection

为加强信号交叉口行人违章管理,分析行人违章过街决策规律,依据行人违章决策机理,在计划行为理论(TPB)中添加"过去行为""出行环境"因素,通过设计调研指标问卷,同步观测行人违章内部心理感知及外部交通环境因素,采用单因素方差分析及独立样本T检验方法,分析违章行人个体属性对过街决策的影响,探讨不同群体间违章决策差异。研究显示:性别、学历属性对违章行为决策无显著性影响;年龄群体在知觉行为控制、出行环境因素中具有显著性差异;驾驶经历群体在主观规范、知觉行为控制因素中具有显著性差异。

This paper is conducted for better management of violation behavior at signalized intersection and studies the decision making rule of pedestrian violation.Based on the mechanism of decision making of pedestrian violation,variables of past behavior and travel environment have been added to the theory of planned behavior. By designing survey questionnaire index system,synchronously parameters of psychological characteristics of pedestrian violations and traffic environment parameters are estimated.Methods of single factor variance analysis and independent sample T test are used to analyze the influence of individual attributes on the decision making by pedestrian violation,and the difference between different groups is studied.The result indicates that：properties of gender and education background have no significant influence on illegal behavior decision making;different age groups have significant differences in the factors of perceived behavioral control and travel environment;experienced driving groups have significant difference in the factors of subjective norm and perceived behavioral control.
