Problems solved by technology

However, it is difficult for the actual on-site operation department to accurately grasp the law of passenger flow on the road network and the development trend of passenger flow in the future, so congestion control is still mostly based on the station level and line level
Moreover, due to the lack of methods and means to predict the state of road network congestion, the congestion control adopted by the on-site operation department is mostly incident control when congestion occurs or post-event control after congestion occurs

Embodiment 1

[0062] The embodiment of the present invention is aimed at the forward-looking correlation control method of urban rail transit road network congestion control. Firstly, the urban rail transit road network operation simulation system is used to pre-push the road network congestion state, and then the passenger flow source retrospective calculation is designed to determine the passenger flow of each congested station. Source information, on this basis, construct the urban rail transit road network collaborative limit model and solve the model, formulate the road network collaborative current limiting scheme, and finally use the road network collaborative current limiting scheme as the simulation input of the urban rail transit road network operation simulation system Simulation experiments to verify the impact of the current limiting scheme on road network operations.

Embodiment 2

[0116] Taking the Beijing subway in 2013 as an example, a forward-looking correlation control method of the present invention for urban rail transit network passenger flow congestion will be described in detail below.

[0117] Step 1. Pre-push the congestion state of the urban rail transit network;

[0118] In the example, there are 17 operating lines and 231 operating stations in the road network. Based on the train operation diagram and passenger flow OD of a working day in March 2014, there is no passenger flow control scheme. In view of the passenger flow congestion at the station, in order to demonstrate the effect of the model, the maximum capacity of the station platform is temporarily taken as 3000. After using the urban rail transit road network operation simulation system to simulate and pre-push the road network operation status, according to the display function of the simulation system, it is determined that passenger flow congestion occurs at the Wangjing West a...

Abstract

The embodiment of the present invention provides a forward-looking correlation control method for urban rail transit road network passenger flow congestion. The method mainly includes: based on the actual operation data, using the urban rail transit road network operation simulation system to predict the congestion state of the urban rail transit road network, and determine the station where passenger flow congestion occurs; Calculate and obtain the passenger flow source information of the station where passenger flow congestion occurs; on the basis of the passenger flow source information of the station where passenger flow congestion occurs, build a road network collaborative current limiting model and solve the model to formulate a road network collaborative current limiting model. Program. In the present invention, by formulating a road-network cooperative current-limiting scheme, aiming at congestion-related stations, the current-limiting station, current-limiting time, and flow-limiting are reasonably set, so as to avoid road network passenger flow congestion in urban rail transit in a forward-looking control manner.

Description

technical field [0001] The invention relates to the technical field of urban rail transit passenger flow control, in particular to a forward-looking correlation control method for urban rail transit road network passenger flow congestion. Background technique [0002] With the realization of urban rail transit network operation, passenger flow congestion at one station in the road network is affected by passenger flow at multiple stations. Therefore, the control of passenger flow congestion under networked operating conditions needs to consider the correlation between multiple stations in the road network. At present, research on passenger flow congestion control in urban rail transit networks is no longer limited to station-level control and line-level control, and pays more attention to network-level collaborative control. However, it is difficult for the actual on-site operation department to accurately grasp the law of passenger flow on the road network and the developm...
