| Currently, development of China’s urban rail transit has entered into a new era, the feature of mass network is increasingly significant with continuous investment of new transit lines, and also the operation management mode has transited from independent operation to multi-line integrated operation. The network interrelated each rail line of urban rail transit which increasing the requirements of network operation coordination.We took the coordination of network operation and organization as a huge target and started research by defining network coordination of operation and organization in order to enhance service management level of urban rail transit mass network system.In this paper, we firstly analyzed service features on network patterns and traffic characteristics in the urban rail transit mass network, gave the schedule method of route and transfer nodes importance, demonstrated time and spatial distribution features and passenger differences between network and single line; then we researched new issues, models,methods that adapting the network traffic feature including collinear operating mode, multi-route operating mode and skip-stop mode according the connotation of operation management coordination in urban rail transit network; moreover, we analyze the convergence relationship of last train in network to the key point of transfer station for building a network optimization model based on connotation relationship giving a calculation order of last trains on the mass network, and lastly we analyze the mechanism of waiting time and number with transferring,and in this process, we described traveling time of transferring by distribution weibull, then build a coordination optimization model of the trains for optimizing arrival and send time in transfer stations by translation, at the same time we design a hierarchical coordination algorithm based on network-wide integrated coordination which had been vivificated by a urban rail transit mass network. |
