A review of passenger flow assignment model and algorithm for urban rail transit network

The passenger flow assignment for urban rail transit is the basic theory to estimate the flow distribution in network. Firstly, this paper introduced the passenger flow assignment study with comparative analyzing the existing models' characteristics of the supply network framework modeling, passengers' travel behavior hypothesis and passenger flow assignment principle. Based on the classification of the assignment model, this paper focused on the network route searching algorithm, model solving algorithm and passengers' behavior simulation and distribution simulation algorithm in the assignment model. Finally, the passenger flow assignment research prospect under the new situation in China urban rail transit network operation is proposed.
