A method and a system determine a subsequent number of guided vehicles occupying a track section of a railway network. The system has a trackside device configured for controlling and managing a movement authority of a guided vehicle for a track section and at least one neighboring trackside device. Each neighboring trackside device is configured for controlling and managing a movement authority for a directly neighboring track section. The trackside device is configured for calculating the subsequent number of guided vehicles from a number of guided vehicles occupying the track section previously determined by the trackside device and information received from each neighboring trackside device regarding a number of guided vehicles entering, from the track section. The directly neighboring track section is controlled by the neighboring trackside device and a number of guided vehicles leaving the directly neighboring track section for the track section.

According to one embodiment, a moving block signaling headway calculation system recursively executes a process until an interval reaches a limit value. The process includes calculating headway values for a plurality of points on the running section for each interval, extracting a section between adjacent two points, in which an amount of variation in the headway values between the adjacent two points exceeds a threshold value, a section between two points before and after a front point and an end point of a point or a section where a headway value changes from rise to fall, or a section between two points before and after a front point and an end point of a point or a section where a headway value changes from fall to rise, and subdividing the interval in the extracted sections.

The present disclosure discloses a vehicle on-board controller centered train operation control system, the control system comprises intelligent vehicle controllers (IVOCs) provided on respective trains, the IVOC comprises a vehicle-vehicle communication device, an active identification device and a master control device. With such control system, rear-end train or more serious accidents may be avoided in case that there is a train without communication equipment or with equipment failure operation in front, or an obstruction impeding train operation appears in front of the train. Further, the control system provided by embodiments of the present disclosure enables a train to operate with a relatively high speed under the premise of safe operation, and improves operation efficiency and reliability.

The present invention provides an automatic train protection method, a vehicle on-board controller and a train based on vehicle-vehicle communication. The method includes: after a present train runs onto a main track, determining an OC with which the present train needs to establish communication; communicating, by the present train, with the OC to obtain train identifiers of all trains within the jurisdiction of the OC; respectively communicating, by the present train, with the train corresponding to each train identifier to obtain current running information of the train corresponding to each train identifier; identifying a front communication neighbor train of the present train; determining that no hidden train exists between the present train and the front communication neighbor train; and calculating current movement authority MA of the present train according to the current position information of the present train and of the front communication neighbor train.

An interlocking device performs route control for trains based on: first operation diagram information as train operation diagram information on a train which runs between stations; second operation diagram information as train operation diagram information on a train which moves in a station yard; and on-track position information on the trains. The interlocking device performs control with time on a signal and/or a switch on a route of a train based on different information according to whether a predetermined condition is satisfied.

An urban rail transit train control system based on vehicle-vehicle communications, comprising an intelligent train supervision (ITS) system, a train manage center (TMC), a data communication system (DCS), and an intelligent vehicle on-board controller (IVOC) provided on each of trains, the ITS system. The TMC and the IVOC are communicatively coupled by the DCS, and IVOCs of the trains communicatively coupled by the DCS. IVOCs of all the trains report first train operation information to the ITS system and second train operation information to the TMC in accordance with a predetermined period. The TMC sends the received second train operation information to the ITS system. The ITS system determines a following train that needs a virtual coupling operation and a head train corresponding to the following train, and dispatch a virtual coupling operation instruction to the head train IVOC to perform a virtual coupling operation of trains.
