公交出行信息条件下出行者通勤出发时间选择影响因素

Influence factors of traveler's commuting departure time choice behavior under public transit information

为提高公交出行信息服务水平,研究了公交出行信息条件下出行者通勤出发时间选择影响因素.采用均匀设计方法设计调查问卷,并在湖北省襄阳市开展了意向调查.考虑到出行者出行到达时间对出发时间选择有影响,引入了早到延误和晚到延误因素,建立混合Logit模型,对出行者出发时间选择影响因素进行了量化分析.结果表明:早到延误对出行者在公交出行信息条件下的出发时间选择有显著影响,且与晚到延误的影响作用不同;出行距离、道路拥堵信息和公交换乘信息会显著影响出行者的出发时间选择,公交车辆位置信息不会对出行者的出发时间选择产生显著影响;出行者个体的受教育程度、收入、日常乘坐公交情况等也是影响其出发时间选择的主要因素.

To improve the level of public transit information service,the influence factors of traveler＇s commuting departure time choice behaviors under public transit information are studied.The uniform design method was used to create survey questionnaire,and the stated preference survey was carried out in Xiangyang City,Hubei Province. Considering the impact of traveler＇s arrival time on his / her departure time choice,schedule delay early（ SDE） and schedule delay late（ SDL） are introduced to develop the mixed Logit model,and the influence factors of traveler＇s departure time choice are quantitatively analyzed. The results showthat the influence of SDE on traveler＇s departure time choice is significant,and it is different from the influence of SDL. Traveler＇s departure time choice is influenced significantly by travel distance,road congestion information and transit transfer information,but it is not influenced significantly by bus location information. The education,income and daily taking bus situations of a traveler are also main influence factors of his / her departure time choice.
