Method and system for pre-controlling oversaturated passenger flow on platform of urban rail transit station

Abstract

The present disclosure provides a method and system for pre-controlling oversaturated passenger flow at an urban rail transit station platform, which acquires hardware facility parameters of rail transit station halls, train information parameters, and passenger flow service parameters; extracts passenger flow data in real time, and pre-discriminates the oversaturated state of the platform , if it is determined that the passenger flow on the platform is about to reach an oversaturation state, turn on the corresponding signal device arranged on the hall floor to control the passenger flow on the hall floor; determine the minimum arrival rate of the passenger flow on the platform according to the obtained parameter information, and then determine the remaining available platform The maximum release time required to accommodate the passenger flow, and set the opening time of the signal device prohibition signal; according to the obtained parameter information, on the premise that the passenger flow rate of each train does not exceed the channel capacity limit, set the corresponding release signal opening time ;According to the set opening time of the prohibition signal and the opening time of the release signal, a timing scheme is formed to control the work of the signal device. Can effectively reduce passenger flow congestion.

Description

technical field [0001] The disclosure belongs to the technical field of urban rail transit passenger flow control, and in particular relates to a method and system for pre-controlling oversaturated passenger flow on an urban rail transit station platform. Background technique [0002] The statements in this section merely provide background information related to the present disclosure and do not necessarily constitute prior art. [0003] With the rapid development of the urban economy, the traffic travel demand of residents has increased significantly. Urban rail transit has become the preferred mode of transportation for major cities to increase transportation supply due to its outstanding advantages such as large transportation volume, fast speed, punctuality, safety, convenience, and environmental protection. At the same time, safe and efficient operation of urban rail transit has become an important goal of public transport development. [0004] Due to the large trave...

Problems solved by technology

However, the guidance information is only displayed on the information panel or other electronic devices. Passengers may give up searching for the position of the carriage due to the cumbersomeness of the search, and only analyze the OD data of passenger flow, so it is impossible to monitor the distribution of passenger flow on the platform in real time, and then it is impossible to realize the oversaturation of the platform. Efficient and balanced guidance of passenger flow in the state
