信号交叉口过渡信号期间行人过街选择行为分析

An Analysis of Pedestrian Crossing Decision Behavior during Interval for Pedestrian Signal at Signalized Intersection

主要对行人过渡信号期间信号灯不同显示方式下行人过街的影响因素进行分析,并建立了行人过街行为的预测模型.使用视频和问卷调查法,在重庆市3个交叉口进行拍摄,记录下行人在过渡信号期间的过街行为.同时,对通过交叉口的行人使用截断式调查的方式进行问卷调查.问卷基于计划行为理论进行设置,为了验证问卷的有效性和科学性,调查后对问卷进行了信度和效度验证,结果表明该问卷能够反映过渡信号阶段行人过街选择行为的决策机理.同时,通过上述调查分析结果表明,心理因素中行人的态度对行人过街行为影响最大.用Pearson x2检验法,分析了影响行人选择行为的因素,并建立了二元Logit模型预测行人在过渡信号期间的过街行为.

The object of this study is to analyze the main factors influencing the pedestrian＇s behavior during the pedestrian interval time under different showing condition at signalized intersection, and set up the model to predict the pedestrian＇s behavior at the interval time. The video and questionnaire survey methods are used in the study. The videos recorded the pedestrian crossing behavior at three intersections in Chongqing, China. And the pedestrian＇s choice behavior of crossing intersection was investigated at the interval time under different showing conditions. Simultaneously, the intercept survey is used to complete the questionnaire through inquiring the crossing pedestrian. The theory of planned behavior（TPB） is used in designing the questionnaire, and the verification of reliability and validity of the questionnaire proves that it can reflect decision-making mechanism of pedestrian behavior. The study results indicate that the pedestrian behavior at the pedestrian interval time is mainly influenced by the attitude. Then, the Pearson chi-square test is used to analyze the pedestrian＇s choice factors. According to the results of analyzing, the binary Logistic model is set up to predict the pedestrian＇s behavior at the interval time.
