Multi-station cooperative flow limiting method for urban rail transit network

Abstract

The invention relates to a multi-station cooperative flow limiting method for an urban rail transit network. The method comprises the following steps: S1, acquiring urban rail transit data; s2, constructing an urban rail transit passenger travel path selection model in a crowded state, converting a passenger path selection behavior problem into a parameter estimation problem, and obtaining a passenger flow distribution result; and S3, constructing a multi-station cooperative flow limiting model, and solving the multi-station cooperative flow limiting model to obtain a station flow limiting scheme. Compared with the prior art, the purposes of optimizing the supply-demand relation and relieving passenger flow congestion are achieved, the station congestion phenomenon is effectively relieved, and the efficiency and safety of urban rail transit network operation are improved.

Description

technical field [0001] The invention relates to the technical field of intelligent transportation, in particular to a multi-station cooperative current limiting method in an urban rail transit network. Background technique [0002] In recent years, urban rail transit has achieved rapid development in my country due to its large capacity, speed, punctuality and safety. The rail transit in Beijing, Shanghai, Guangzhou, Shenzhen, Chengdu and other big cities has entered a new era of networked operation and management. stage. With the increasing improvement of the urban rail transit network, passengers travel more conveniently. However, while the urban rail transit system is attracting a large number of passengers, its congestion has become increasingly serious, which not only seriously affects the efficiency of network operations, but also greatly reduces the safety of operations. [0003] Commonly used methods for relieving passenger flow congestion in urban rail transit syst...

Problems solved by technology

However, the networked operation of urban rail transit has strengthened the interconnection between the original independent operating lines. The current limiting plan formulated according to a certain station or a certain line can relieve the passenger flow pressure of a single station or a single line, and realize the relief of local passenger flow congestion. However, due to the lack of consideration of the synergy between the station and the road network, it is impossible to ensure the optimal operation efficiency of the entire urban rail transit network
