基于持续模型的行人过街行为

Pedestrian crossing behaviours based on duration model

在行人过街行为实测数据基础上,建立了基于危险的行人过街等待持续模型。分别采用非参数形式和参数形式的基准危险函数的模型框架,对影响过街行为的因素,特别是违章过街的影响因素进行了分析。研究结果表明,非参数形式模型对行人过街等待行为描述更为精确;行人的过街行为呈现明显的时间相关性,违章倾向随等待时间的增加而增加。本研究可为行人交通行为分析和行人交通仿真提供有益参考。

A waiting duration model of pedestrian crossing was proposed by using hazard-based duration models based on observed data.The framework of baseline hazard adopted parametric shape and non-parametric shape.The factors that could effect crossing behaviours were analyzed,particularly for crossing in violation of traffic rules.The results show that the non-parametric model can present an accurate description of waiting behaviours.The crossing behaviours have significant dependence on time,the hazard of traffic violation increase when time elapse.The results provide a useful reference for pedestrian crossing analysis and traffic behaviour simulation.
