摘要
考虑旅客选择行为和运输供给间的相互影响关系,设计了基于供需匹配的两阶段客流分担率计算方法。第一阶段从旅客出行意愿出发,考虑旅客选择行为的差异和不同通道内客流结构的差异,建立分客流类型、分列车等级的客流分担率计算模型;第二阶段从运输供给出发,基于旅客效用值设计了客流转移概率的计算方法,并基于此给出客流分担率的修正方法。以武广通道为例,对本文提出的方法进行了验证分析。结果表明:基于运输供给修正后的客流分担率与实际客流分担率更为接近。
Sharing of passenger flow in railway corridors is important to train planning.Considering the influence of transport offer on passenger choices,this paper proposed a two-phase approach to identify the share rate of passenger flow.For the first phase,starting from the travel demand of passengers and taking into account the differences in passenger choices and in passenger flow structures in different corridors,the Logit model was established to compute the share rates of passenger flow by classified passenger flow and classified classes of trains.For the second phase,starting from the transport offer and basing on the method of computing the transfer probability of passengers from one class of train to another class of train according to the utility of passengers,the method for rivision of share rates of passenger flow was designed.The proposed approach was applied in identiflying the share rate of passenger flow in the Wuhan-Guangzhou railway corridor.The results show that the share rate of passenger flow modified in view of transport offer is closer to the actual share rate of passenger flow.
