Problems solved by technology

In complex areas with dense rail transit network and train flow, the method of still adopting train operation plan combined with train interval allocation based on subjective experience gradually shows its backwardness. Due to the influence of various random factors, it is easy to cause congestion in traffic flow tactical management and reduce the safety of traffic system operation; (2) The train scheduling work focuses on maintaining the safe interval between individual trains, and has not yet risen to the strategic management of train flow. At the macro level; (3) The train deployment process mostly depends on the subjective experi

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 planning method for resolving conflict of subway trains. The planning method includes the following steps of acquiring the train movement path, predicted at every sampling time, of each subway train in the future period through a subway traffic control center; establishing an observer for observing from the continuous dynamics of the train to the discrete conflict logics and mapping the continuous dynamics to the conflict state expressed by discrete observation values; monitoring the hybrid dynamic behaviors of a subway traffic hybrid system when the system may violate the traffic control rules and giving alarm information to the control center; and performing robustness double-layer planning on the train movement paths by means of an adaptive control theory when the alarm information occurs and transmitting the planning results to the trains.

Description

technical field [0001] The invention relates to a planning method for conflict relief of subway trains, in particular to a planning method for conflict relief of double-deck subway trains based on a robust strategy. Background technique [0002] 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 unprecedented peak period of rail transit development. Some cities have shifted from line construction to network construction, and urban rail transit networks have gradually formed. In complex areas with dense rail transit network and train flow, the method of still adoptin...
