Background At present, a communication-based train control system (Communication Based Train Control, CBTC) is mainly adopted in the urban rail transit field, and compared with the traditional interlocking, the blocking system adopted by the CBTC further shortens the train running interval and improves the running capacity. However, with the development of economy, particularly rapid development of urban circles and urban groups, great pressure is brought to rail transit. In order to solve the problems of the traditional CBTC system, a train operation control system (Vehicle Based Train Control, VBTC) based on train-to-train communication is generated, and the system becomes the main development direction of the next-generation urban rail transit train control system. However, based on the requirements of safety, reliability and driving efficiency, the existing VBTC system still uses a resource allocation mode taking a complete route as a unit, so that in some operation scenes which cannot handle the complete route in time, the train cannot obtain driving resources allocated by a resource controller (Resource controller, RC) in time, and the train cannot turn back in situ and quickly finish train upgrading, thereby affecting the operation efficiency. Therefore, how to better implement train route handling in VBTC systems has become a technical problem to be solved in the industry.
