Urban rail transit network is composed of static network physical structure and dynamic train working diagram, whose accessibility evaluation should include both spatial and temporal characteristics. This paper proposed a comprehensive dynamic accessibility evaluation model of urban rail transit network. Its spatial characteristics were determined by station passenger flow, path impedance etc., while its temporal characteristics were defined by train departure intervals, train carrying passenger flow etc. And the dynamic accessibility index can be calculated through these factors, OD path accessible set and passenger route preference. Finally, Shanghai metro network was used as a case study to show the calculation process and analysis result of the proposed model. Result showed that the model could remedy the shortcoming that some traditional accessibility index models did not take into account temporal characteristics (metro service frequency, service level et al), and it could also give a reasonable allocation for urban rail transport capacity by analyzing the whole day dynamic accessibility index.
