Embodiment

[0146] In order to illustrate the present invention more clearly, the present invention will be further described below in conjunction with preferred embodiments and accompanying drawings. Similar parts in the figures are identified with the same reference numerals. Those skilled in the art should understand that the content described in detail below is illustrative rather than restrictive, and should not limit the protection scope of the present invention.

[0147] In this example, Harbin Metro Museum Station is selected as the prototype of the research, and the subway station is modeled according to the actual passenger flow data collected. Combined with the configuration of various facilities in the subway station and their related attributes, the knowledge element is used to analyze the subway station and carry out dynamic evacuation. During the construction of the station knowledge element, the passenger flow changes in the emergency state and the impact of the station's ...

Abstract

The invention relates to a dynamic emergency evacuation method for failure of urban rail transit lines, which relates to the technical field of rail transit control. The problem of secondary propagation of stranded passenger flow in network caused by limited evacuation capacity of single station is solved. The method comprises: attribute set and running state set of each station in the network being established; analyzing station passenger flow state ; SAS software being used to predict the passenger flow and simulate the arrival process of the passenger flow; determining evacuation starting point and evacuation end point; constructing the emergency rail transit cooperative evacuation network; constructing the dynamic path selection model in the range of destination; determining the best evacuation path; determining the number of emergency buses required and the interval between the buses; determining the distribution of passenger flow to be evacuated to the evacuation subway station;according to the parameters of rail transit train, determining the train transport capacity, combined with the passenger flow of subway station, to allocate the resources of train transport capacity,to formulate the train operation plan in emergency state. The invention increases the passenger flow evacuation capacity of a single node to improve the efficiency of network evacuation.

Description

technical field [0001] The invention relates to the technical field of rail traffic control, in particular to an emergency evacuation method for a rail traffic network. Background technique [0002] Urban rail transit, as the main public transportation mode for residents to travel, has been developed and expanded in various cities. Rail transit lines and stations are no longer separate individuals, but are interconnected as a whole to serve the public. This interrelated feature makes the rail transit network emergency, in addition to causing a certain impact on the site where the incident occurred, it will also cause some line service interruptions, and the passenger flow of the faulty site will be affected by other transportation modes in the network due to untimely evacuation, such as Ground traffic, resulting in secondary transmission of large passenger flow. Therefore, in addition to focusing on the evacuation inside the subway station, the emergency evacuation also des...
