Problems solved by technology

In my country, although the network pattern of some urban rail transit lines has gradually formed, the degree of networkization is not high. Most of the emergency rescue theories tend to be based on the traditional single-line thinking, resulting in each line forming its own system and fighting on its own, and duplication of resources between lines. The configuration cannot be shared, and the research on the site selection of emergency rescue stations lacks thinking and design at the network level, ignoring the influence of the characteristics of the network topology of the rail transit system on rescue work, resulting in poor network emergency balance.
At the same time, most of the existing research is pure theory and method research. The main research content focuses on site selection model and algorithm design, and few empirical analyzes are carried out in combination with the actual status quo of my country's rail transit.

Abstract

An urban rail traffic emergency rescue station siting method and device are provided. The method comprises: using urban rail traffic stations as nodes and rail lines between the urban rail traffic stations to establish an undirected network model; calculating network characteristic indexes of the undirected network model, including degree, betweenness, compactness and characteristic vectors; acquiring, under a set attack strategy, rail traffic network node comprehensive vulnerability index according to the relationship between the number of failure nodes and network global efficiency; acquiring a coverage function according to the correspondence, which is determined via the vulnerability index, between vulnerability level and response time interval limit; constructing a rescue station siting model according to the comprehensive vulnerability index and the coverage index. According to the method and device, vulnerable nodes in a network are recognized in conjunction with the complex network theory, the vulnerability index is introduced during construction of the siting model in order to protect the vulnerable nodes, and stability and emergency efficiency of a whole rail traffic system rescue network are improved.

Description

technical field [0001] The invention relates to the technical field of urban rail transit emergency treatment, in particular to a site selection method and device for an urban rail transit emergency rescue station. Background technique [0002] With the gradual formation of rail transit network pattern, the continuous growth of passenger flow and the continuous shortening of peak hour departure intervals have brought a series of new safety issues and challenges to traffic organization and operation management. During peak hours, rail transit has high passenger flow intensity, short driving intervals, and difficult adjustment of driving organization. Once a major emergency occurs at a certain station or a certain line, it will quickly affect adjacent lines or even the entire line network, causing huge economic losses. Passengers were injured. Therefore, after an urban rail transit emergency occurs, efficient emergency rescue becomes a key way to curb the online dissemination...
