Abstract: On the condition of urban rail transit network operation and “one vote transfer”, it often occurs that passengers in the last train are unable to reach the destination because of the transfer failure. This paper adopted the thought of hierarchical progressive convergence, coordinated the division level based on relationships between reference line and other lines. Based on the last train transfer passenger flow and direction, a model of the last train time schedule was established according to the hierarchical coordination. The model was optimized in two aspects: specific direction of connection and departure time intervals. The paper calculated and optimized the last train time schedule in Guangzhou urban rail transit network. The result shows that the optimized last train time can better adapt to the last trains passenger travel demand, and verifies the validity of the model and optimization method.
