Planning method of travel path for urban rail transit passengers in emergency

Abstract

The invention discloses a planning method of a travel path for urban rail transit passengers in an emergency. The method comprises the steps that S1, physical network information, operating network information and emergency information of urban rail transit are acquired; S2, influence space and influence time of the emergency in an urban rail transit network are determined based on the acquired information, and the influence time of the emergency is published in the influence space; S3, section passenger flow of the urban rail transit network in the emergency is predicted by integrating the urban rail transit and other means of transportation and considering travel selection behavior characteristics of the urban rail transit passengers in the emergency; and S4, the travel path is planned for the passengers based on a path planning request of the urban rail transit passengers by comprehensively considering other means of transportation according to a valid path state and a passenger flow congestion degree in the urban rail transit network. Through the method, technical support is provided for an information publishing range in the emergency, and a technical base is laid for providing individualized travel information service for the passengers.

Description

technical field [0001] The invention relates to the technical field of urban rail transit. More specifically, it relates to a method for planning travel routes of urban rail transit passengers under emergencies. Background technique [0002] Urban rail transit has gradually become the backbone of the urban passenger transport system due to its large capacity, fast speed, accurate time, less pollution and good safety. The frequent occurrence of various emergencies, such as the failure of operating facilities and equipment functions, will lead to the interruption of line train operation, line outage and even line network paralysis, which greatly reduces the operational reliability of the rail transit system. Especially in the context of the rapid development of urban rail transit, some urban rail transit has entered the era of network operation, such as Beijing, Shanghai, Guangzhou and so on. Compared with single-line operation, in the era of networked operation, emergencies...

AI Technical Summary

Problems solved by technology

Publishing emergency information on unaffected stations and lines will cause panic among passengers and reduce passenger satisfaction with rail transit

In addition, if passengers make their own travel decisions, it is difficult for passengers who are not familiar with the road network structure to adjust their travel routes in a timely manner; crowded
