Urban rail transit part route operation regulating method in emergency scene

Abstract

The invention discloses an urban rail transit part route operation regulating method in an emergency scene. The method comprises the following steps of S1, obtaining the rain operation and route parameters of a rail route, the position of an emergency event, and the fault parameter, so that the interruption time is determined; S2, determining an alternative part route foldback scheme according to the train operation and route parameter, the position and the fault parameter of the emergency event, and the interruption time; S3, building the total target function of the rail route operation regulation according to a station total retention number model and the total delay time model of arrival and departure of all trains in the part route foldback scheme; S4, solving the total target function by using a particle swarm algorithm of the convergence factor and the weight; determining the optimum part route foldback scheme. When the part route foldback scheme is used for regulating the rail transit operation under the condition of the emergency event, the problem of station passenger retention can be well solved; the rail train is promoted to recover the normal operation.

Description

technical field [0001] The invention relates to the field of urban rail transit. More specifically, it relates to a method for adjusting the operation of urban rail transit small intersections in emergencies. Background technique [0002] In recent years, with the development of the economy and the process of urbanization, the urban areas of various countries have been expanding continuously, and the population has increased rapidly, which makes the urban traffic problems more and more serious. Urban rail transit is a large-capacity, fast, convenient, environmentally friendly and energy-saving public transportation method. The development of urban rail transit has become the choice of large cities at home and abroad, and has gradually become an effective way to solve traffic problems in large cities. With the continuous growth of the demand for subway passenger transport, the subway operating companies in various cities need to continuously improve their operational service...
