Suburban travel mode choice considering transit accessibility of stops in public transport

考虑公交站点可达性的郊区出行方式选择

To analyze the influence of the transit accessibility of stops on the travel mode choices of suburban residents,the number of the lines passing by the stops within an accessible range of the resident origin and destination(OD)points and the average waiting time are used as the indexes of the transit accessibility of stops.Due to the correlation between travel time and accessible range,the transit accessibility of stops is contrasted as piecewise variables constrained by travel time.Taking the Jimei District of Xiamen,China,as an example,a binary logistic regression model of the suburban travel mode choice is constructed.The results show that it is necessary to construct transit accessibility of stops as piecewise variables.With a higher transit accessibility of stops,more residents will choose public transport.The choice of the travel mode is correlated with family attributes and personal characteristics.Morning and evening peak hours and travel distance have little effect on the choice of travel mode.Compared with the travel in urban areas,residents often chose public transport for travel within the suburbs.This research provides a basis for encouraging public transportation priority policies and decision making for transport planners in the suburbs.

为了分析站点的公交可达性对郊区居民出行方式选择的影响,采用居民出行OD点可达范围内的站点线路数和平均等待时间作为站点可达性指标.基于出行时间与可达范围的相关性,将站点可达性构造为受出行时间约束的分段变量.以中国厦门市集美区为例,建立了包含站点可达性指标的郊区出行方式选择的二元logistic回归模型.结果表明,站点可达性越高,居民选择公交出行的可能性越大.出行方式的选择与家庭属性和个人特征密切相关,早晚高峰和出行距离对居民出行方式的选择影响不大.郊区和市区之间的出行相比,居民通常选择公共交通工具在郊区内出行.研究结果可以为鼓励公交优先政策和郊区的交通规划提供决策依据.
