基于GIS的城轨交通短驳公交乘客出行时间算法研究

GIS-based Passenger Travel Time Algorithm for Urban Rail Transit Feeder Bus

通过分析城市轨道交通短驳公交的特征以及出行过程中受到的影响因素,建立短驳公交地理信息系统(GIS)数据库,对出行过程进行精确描述,提出改进的算法。最后通过上海普陀区某小区的计算实例将本方法与常用的其他方法进行精度比较,对本方法的实用性和有效性进行了验证。

The small shuttle bus features with flexibility for urban rail transit. By using geographic information systems （GIS） network, the paper makes analysis on improved passenger travel time calculation. Through analysis of characteristics and impact factors during the trip by taking urban rail transit feeder bus, the establishment of feeder bus GIS database provides accurate description on trip, an improved algorithm is put forward. Finally, the paper makes an accuracy comparison of the calculation examples for an area in Shanghai Putuo district with the method mentioned above and other commonly used methods, the practicality and effectiveness of the method are validated.
