Problems solved by technology

The train coordinated control scheme under the complex road network operating conditions needs to calculate and optimize the operating status of a single train on the regional traffic network at the strategic level, and implement collaborative planning for the traffic flow composed of multiple trains; while the multi-train Running conflict resolution is based on the prediction of subway train trajectories. The running state of trains often does not completely belong to a specific motion state. At present, there is no effective real-time prediction method for subway train trajectories.

Embodiment 1

[0039] A subway traffic flow optimization control system includes a line topology generation module, a data transmission module, a vehicle terminal module, a control terminal module, and a trajectory monitoring module. The trajectory monitoring module collects train status information and provides it to the control terminal module.

[0040] The control terminal module includes the following submodules:

[0041] Conflict-free trajectory generation module before train operation: According to the planned operation timetable of the train, the train dynamics model is established first, and then the train operation conflict pre-allocation model is established according to the train operation conflict coupling point, and finally the conflict-free train operation trajectory is generated.

[0042] Short-term trajectory generation module for train operation: According to the real-time status information of the train provided by the trajectory monitoring module, use the data mining model ...

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...
