地铁站可达性和便利性对通勤选择的影响研究——以上海市中心城区地铁站为例

Study on the Impact of Accessibility and Convenience of Metro Stations on the Commuters' Choice——a Case Study of Metro Station in Downtown Shanghai

为了研究轨道交通中地铁站点的可达性和便利性特征对通勤出行者做出站点选择行为的影响效应,从而为我国进行城市轨道交通建设布局规划提供一些可供参考的思路,选取上海市中心城区地铁站点的集计数据,结合地理特征信息,建立基于随机系数的通勤出行者离散选择模型。研究发现地铁站点可达性中的出行者与地铁站之间的距离及周围1800米内经过的公交车线路数,便利性中的拥挤程度、出入口数,及地铁所处线路对通勤选择行为有显著影响。合理规划安排地铁站点需考虑地铁站选址与居住地及与公交接驳的平衡,可适当增加地铁站内空间及出入口数以疏导客流,减轻拥挤度对通勤选择行为的影响。

In order to investigate the impact of metro stations’accessibility and convenience characteristics on the commuter choice of stations,which can provide some useful ideas for the city subway construction allocation plan in the future,we gather the aggregate data and the geographic information of the metro stations in the city centre of Shanghai,and build a commuter discrete choice model based on random coefficients.It is found that the distance between the commuter and the station and the number of bus lines with 1800 metres of the station of the accessibility characteristic,the crowd degree and the number of entrances of the convenience characteristic,and the metro line of the station all have impacts on the commuters?choice.Appropriate metro stations plan needs to consider the balance between the location of the station and the residence and the connection with buses.The space and entrances of the station can be increased properly to lead the passengers,so that to decrease the influence of the crowd degree on the commuter choice.
