Urban rail traffic passenger flow precise control method and system based on passenger flow demand

Abstract

The invention provides an urban rail traffic passenger flow precise control method and an urban rail traffic passenger flow precise control system based on a passenger flow demand and relates to the technical field of operation management of urban rail traffics. The method comprises the following steps of constructing a passenger flow demand matrix according to passenger travel information; determining a passenger flow control decision variable according to the passenger flow demand matrix; constructing a passenger flow control linear constraint according to the passenger flow control decisionvariable; constructing a passenger flow control optimization model with the shortest passenger flow waiting time as a target according to the passenger flow control linear constraint; and solving thepassenger flow control optimization model to obtain a passenger flow precise control scheme, wherein the passenger flow precise control scheme is input a control system as a passenger flow control parameter to realize passenger flow precise control. With the urban rail traffic passenger flow precise control method and the urban rail traffic passenger flow precise control system based on the passenger flow demand, the capacity of a train can be fully utilized, all passengers arrival at a platform can take the next train, thereby avoiding gathering of the passenger flow at the platform; and while guaranteeing safe operations, the waiting time of passengers is shortened and the operating efficiency is improved.

Description

technical field [0001] The invention relates to the technical field of urban rail transit operation management, in particular to a refined control method and system for urban rail transit passenger flow based on passenger flow demand. Background technique [0002] Urban rail transit (subway, light rail, etc.) has the characteristics of punctuality and reliability, and has become the first choice for most people to commute. It bears a large number of passengers in daily commuting transportation and is the most important transportation corridor for urban transportation. With the sharp increase in the resident population of some megacities (such as Beijing and Shanghai) in my country, the daily commuting trips in the cities also increase sharply. Urban rail transit is facing tremendous pressure in commuting transportation (morning and evening peaks). Trains are overloaded, Phenomena such as platform congestion have become the norm, and incidents such as passengers squeezing door...

AI Technical Summary

Problems solved by technology

[0007] The purpose of the present invention is to provide a refined control method for passenger flow in urban rail transit that can alleviate the accumulation of passenger flow at stations to the greatest extent, improve the transportation speed and train capacity utilization efficiency, and reduce the waiting time of passenger flow while ensuring the safe operation of trains, so as to solve the above-mentioned problems. The existing passenger flow control methods in the background technology affect the safe operation in order to improve the transportation capacity, the passengers are seriously stranded, it is easy to cause congestion, the time cost is high, and the transportation efficiency cannot meet the technical problems of transportation needs
