机动车出行者出发时间选择的影响因素

采用陈述偏好(Stated preference survey,SP)调查法获取机动车出行者的出行行为数据,利用混合Logit模型建立了总体对象和典型对象出发时间选择行为模型。采用不同范围的出行行为数据对模型进行验证,结果表明:出行者的社会经济特性、预计的出行延误信息、对路网的熟悉程度、天气状况信息、交通信息的质量以及出行目的是影响出行者改变出发时间的主要因素,总体对象和典型对象模型存在一定的差异。研究结果揭示了交通信息在不同环境中对出发时间选择行为的影响不同,从而可以为交通信息发布方法和策略的确定提供依据。

Factors influencing motor vehicle travel departure time choice behavior

State Preference(SP) survey was carried out to obtain the travelers' behavior data.To analyze the factors that influence the departure time choice behavior,an overall object model and a typical object model were proposed using the mixed logit model.The proposed models were verified by different ranges of the travel behavior data.The results identify the factors that influence the departure time choice behavior.These factors include the social-economic characteristics of the travelers,the travel delay information,the familiarity of road network,the weather information,the quality of travel information and the travel purpose.There exist certain differences between the overall object model and the typical object model.The results of this study reveal the impact of the traffic information on the departure time choice under different environments,and provide the basis for the dissemination strategy of traffic information.
