摘要
利用杭州市公交线路站点GIS数据和车辆运行GPS数据进行分析,将公交车到站时间分为站点停靠时间和站间行程时间,得到公交车站点之间运行可能总时间的分布概率.通过实际的公交路网结构,定义扩展的公交网络有效路径.在考虑公交线路联合发车频率和根据乘客路径选择的广义成本下,建立出行策略与行程时间不确定下的公交客流分配模型,并将公交线路发车时刻表引入用户均衡模型中,设计了基于扩展网络最短路的Method of Successive Average(MSA)算法求解,通过对两个交通小区间高峰小时的客流分配结果验证模型和算法的有效性.
Using the GIS data of the bus line of Hangzhou City and the GPS data of the vehicle,the bus arrival time is divided into station stop time and station travel time,the distribution probability of the total running time between bus stations is obtained.Through the actual bus network structure,this paper defines the effective path of the extended bus network.Considering the combined frequency of bus lines and the generalized cost based on the passenger route,a transit assignment model is established with uncertainty in travel strategy and travel time.In addition,the bus route departure schedule is introduced into the user balance model.The MSA algorithm based on the shortest path of the extended network is designed.The effectiveness of the model and algorithm is verified by the peak hour passenger flow distribution results between two traffic communities.
