摘要
不同时段内,不同区位的旅客会根据不同的接驳方式及城际列车班次进行城际出行.只根据城际间的出行成本无法准确地刻画旅客的出行.在已知不同时段内城市间各分区OD客流、城际列车时刻表和铁路枢纽布局的前提下,构建城市内接驳交通网络;利用多项Logit模型,建立各个交通分区到铁路车站的接驳子模型;进而利用列车时刻表得到城际出行成本,并考虑列车拥挤造成的成本增加,根据总成本最小原则及接驳子模型,构建分时段的铁路枢纽客流分配模型.通过改进的MSA算法进行求解,得到各时段内各交通分区到铁路车站、以及铁路车站之间的客流量.最后通过算例,对方法的可行性及有效性进行了验证.
In different periods, the passengers of different location will take an intercity travel through various access modes and different frequency of trains. It can't describe passengers' travel accurately only according to the inter-city travel costs. Therefore, with the premise that the OD passenger flow between traffic zones of two cities, intercity train timetable, and railway hub layout are known, it constructed the access traffic network in the city to get the access cost from traffic zones to railway stations and used multinominal Logit model to form the access submodel. Then it used the train timetable to get the intercity travel cost and considered the added cost caused by crowded passengers. According to the principle of minimum total cost and the access submodel, it formed the passenger flow assignment model in different periods, and got the passenger flow between traffic zones and railway stations and between railway stations through improved MSA algorithm. Finally, a numerical example shows the feasibility and validity of the method.
