Abstract: This paper presents a new transit equilibrium assignment model for congested public transport networks with passenger queues at stations, in which both the transit demand and the passenger queues are time-dependent under several continuous periods. The model can estimate simultaneously transit link flows and passenger queues at transit stations in the study period. Especially, in very congested condition, passenger demands can be assigned and passenger queues at the congested stations can also be determined by the proposed model in the study period. Numerical examples are used to illustrate the applications of the time-dependent transit assignment equilibrium model to various demands.

Key words: congestion, transit equilibrium assignment, time-dependent

摘要： 论文考虑了由于公交线路运营能力不足造成的车站排队拥挤现象，在此基础上构造了拥挤条件下公交系统的拟动态均衡配流模型.该模型可自动估计不同时段内拥挤条件下的公交流量和车站的乘客排队，特别是在非常拥挤的情况下(即乘客需求超过公交网络运营能力)也能够进行流量分配，并确定车站的乘客排队长度.因此，该模型较好地反映了公交网络的拥挤效应.所给算例说明了不同需求条件下该公交均衡配流模型的应用.
