Abstract：Research purposes:Simulation technology plays an important role in the urban rail transit network planning and analysis. With the enlargement of the urban rail network scale,the complexity and difficulty in the development of simulation system for urban rail transit network planning increase.To develop the simulation system with high efficiency, an approach to multi-resolution modeling and simulation of urban rail transit system is presented.Research conclusions:(1) An approach to build a multi-resolution simulation system of urban rail transit is presented, by building and integrating transit network architecture models and passenger models in different resolutions. (2) Ahierarchical model of rail transit network topology is built to resolve the problem of spatial consistency in multi-resolution modeling. (3) A polymerization based station simulation model is built to resolve the problem of state consistency. (4) To meet the needs of extensibility and flexibility of the simulation system, an agent-based integration method is applied to develop the simulation system of urbanrail transit network. (5) Arealized example on the application of the simulation model is introduced,which is used to analyze and evaluate a transit network planning.
