Abstract: Transit flow assignment models proposed presently are mainly frequency-based，which has poor schedule information. Aiming at improving the research on schedule-based transit flow assignment，the modified Logit model that adopts transit route independence system in the traditional Logit model is established，avoiding the mutual influence of similar routes. At the same time，a volume restrained ＆ timetable based stochastic user equilibrium (VRT-SUE) model is established， which considers the limitation of vehicle capacity and realizes the flow assignment on transit network using SUE model. The case study result of transit network flow assignment shows that the improved Logit model has better effects than traditional Logit model does; VRT-SUE can satisfy the constrain of vehicle capacity，meanwhile the flow assignments can achieve an equilibrium state in network. Both of the proposed models could be applied to the design and operation management of urban transit network.
