基于计划行为理论的信号交叉口行人违章行为分析

Analysis of Pedestrian Violation Behavior at Signalized Intersections Based on the Theory of Planned Behavior

为有效管理信号交叉口行人违章过街行为,将计划行为理论(TPB)引入行人违章行为决策领域,探究信号交叉口行人违章决策规律.基于信号交叉口行人违章决策机理,增设"过去行为"与"出行环境"因素,提出信号交叉口行人违章计划行为假设模型,通过一致性观测违章行人心理特性与出行交通环境参数,利用结构方程模型(SEM)验证假设模型有效性,确定各违章因素间因果关系及作用大小.研究表明过去违章行为经验为主要影响因素,影响权重系数为0.304,且该因素对出行环境因素正向性影响最高,标准化影响系数为0.46;出行认知缺陷、侥幸心理对违章行为影响性高于从众心理.

In order to effectively manage pedestrian crossing behaviors at signalized intersections,the theory of planned behavior（TPB）was introduced into the decision-making field of pedestrian violations to explore the regularities of decision making of pedestrian violations at signalized intersections.Based on the mechanism of decision making of pedestrian violations at signalized intersections,factors of past behavior and travel environment were added and the hypothesis model of decision making of pedestrian violations at signalized intersections was built.The psychological characteristics of illegal pedestrians and parameters of travel traffic environment were observed through consistency,and the structural equation model（SEM）was used to verify the validity of the hypothesis model and determine the causal relationship and the magnitude of action among various illegal factors.Research shows that the past experience of illegal behaviors is the main influencing factor,and the weight factors coefficient is 0.304.Moreover,this factor has the highest positive influence on the travel environment,and the standardized impact coefficient is 0.46.The influence of travel cognitive deficits and fluke psychology on illegal behaviors is higher than that of conformity psychology.
