Real-time prediction method of metro train track based on robust strategy

Abstract

The invention relates to a real-time prediction method of a metro train track based on a robust strategy, comprising the following steps: firstly, generating a topological structure diagram of a railtransit network according to the planned operation parameters of each train; then, analyzing the controllability and sensitivity of train flow based on the topology diagram, then, according to the planned operation parameters of each train, generating the collision-free operation trajectories of multiple trains, at each sampling time, predicting the train's future travel position based on the train's current running state and historical position observation sequence. The method has a high precision for predicting the trajectory of metro train.

Description

[0001] This application is a divisional application of the invention patent application with the application number: 201510150289.X, the title of the invention is "Real-time Prediction Method of Subway Train Trajectory", and the application date is: March 31, 2015. technical field

[0002] The invention relates to a real-time prediction method of a subway train trajectory, in particular to a real-time prediction method of a subway train trajectory based on a robust strategy. Background technique

[0003] With the increasing scale of large and medium-sized cities in our country, the urban traffic system is facing more and more pressure, and vigorously developing the rail transit system has become an important means to solve urban traffic congestion. The national "Eleventh Five-Year Plan" outline pointed out that large cities and urban agglomerations where conditions permit should take rail transit as a priority area of ​​development. my country is experiencing an unprecedente...
