Abstract: Firstly, the construction background, current situation and necessity of passenger-oriented urban rail transit dispatch and command system is introduced, the data required for the construction of the system and system structure design are emphasized. Then, the key functions such as holographic perception of passenger flow and guidance, passenger flow forecast and analysis, intelligent adjustment of passenger experience and emergency dispatching command are analyzed. The design of the intelligent coordinated linkage engine based on dataflow and its functional advantage are also introduced. Finally, application of the system in urban rail transit is summarized and prospected.
