Urban rail transit network passenger flow limiting method

Abstract

The invention discloses an urban rail transit network passenger flow limiting method. The method comprises steps that model hypothesis is carried out; an urban rail transit network model is established; original data collection and processing are carried out; virtual running lines are constructed; network passenger flow distribution is carried out; the network passenger flow is converted into theroute passenger flow; the virtual running line passenger flow is matched to the actual urban rail transit road network; the commercial optimization solver software is utilized for solution; the totalcontrol flow rate, the control flow number, the time section control flow condition and the optimal strategy for coordinated flow control of stations in the rail transit network in the integral morning peak of the stations in the rail transit network are acquired. The method is advantaged in that the number of inbound passengers, the number of passengers waiting on platforms and the carrying capacity of each train in each time section of the rail transit network can be obtained, and the theoretical basis can be provided for developing traffic flow control measures in the rail transit network.

Description

technical field [0001] The invention relates to the technical field of rail transit flow limitation, in particular to a method for limiting passenger flow in an urban rail transit network. Background technique [0002] At present, the urban rail transit of my country's big cities has entered a new stage of network operation, and the contradiction between the rapidly increasing passenger flow demand and the limited transportation capacity has become increasingly prominent. On the one hand, the phenomenon of overload operation, crowded carriages, and stranded waiting for some lines during peak hours is becoming more and more serious, causing frequent occurrence of passenger hanging doors and car door failures, which in turn leads to a significant decrease in network reliability; on the other hand, due to the The failure of equipment functions and some unpredictable external factors (emergencies, weather effects, etc.) lead to long-term and large-scale delays of trains, causing...

Problems solved by technology

[0013] The disadvantage of the second prior art is that it does not take into account the influence of the passenger flow of the entire rail transit network, resulting in that the accuracy of the line current limiting results cannot be guaranteed, so that the overall rail transit network system cannot be optimized.

[0016] The disadvantage of the third prior art is that it does not fully consider the spatial-temporal distribution characteristics of passenger flow in the rail transit network, and because the time interval adopted is a specified period of time, it cannot approximate dynamic current limiting, so that the passenger flow of the entire rail transit network is limited. The accuracy of the system cannot be guaranteed, resulting in the failure of the entire rail transit system to achieve optimal
