The invention provides an urban rail transit station platform supersaturated passenger flow pre-control method and system. The method comprises the following steps: acquiring rail transit station hallhardware facility parameters, train information parameters and passenger flow service parameters; extracting passenger flow data in real time, carrying out platform supersaturation state pre-judgment, and if it is judged that the platform passenger flow is about to reach the supersaturation state, starting a signal device arranged on a corresponding station hall layer to control the passenger flow of the station hall layer; determining the minimum arrival rate of the passenger flow of the platform according to the acquired parameter information, determining the maximum release time needed forreleasing the remaining passenger flow capable of being contained in the platform, and setting the forbidding signal starting moment of the signal device; setting a corresponding release signal opening moment according to the acquired parameter information on the premise that the get-off passenger flow rate of each train does not exceed the passage capacity limit; and forming a timing scheme according to the set forbidding signal starting moment and the releasing signal starting moment, and controlling the operation of the signal device. Passenger flow congestion can be effectively reduced.

    本公开提供了一种城市轨道交通车站站台过饱和客流预控制方法及系统,获取轨道交通车站站厅硬件设施参数、列车信息参数以及客流服务参数;实时提取客流数据,进行站台过饱和状态预判别,如果判定站台客流即将达到过饱和状态,则开启相应的站厅层布设的信号装置对站厅层客流进行控制;根据获取的参数信息,确定站台客流的最小到达率,进而确定放行站台剩余可容纳客流量所需的最大放行时间,设置信号装置禁行信号开启时刻;根据获取的参数信息,以各列车的下车客流流率不超过通道通行能力限制为前提,设置相应的放行信号开启时刻;根据设置的禁行信号开启时刻和放行信号开启时刻,形成配时方案,控制信号装置的工作。能够有效减少客流拥堵。
