Abstract

The present invention provides an operation system which can finely control the operation of a train in response to the operation state of the train at low cost in a traffic system that uses a process of dynamically setting a path and an operation interval. This traffic control system is provided with: on-board control units installed on trains that are traveling, and an on-ground control unit installed on the ground. The on-board control units are installed on a plurality of trains, respectively, the operations of which are managed by the traffic control systems, perform a track demand on the basis of a delivered operation mode, and deliver information on the track demand to the on-ground control unit. The on-ground control unit controls the progress of the train on the basis of the delivered track demand.

Claims (14)

1. A traffic control system comprising:

on-board control units installed on trains whose operations are managed by the traffic control system and that are traveling; and

an on-ground control unit installed on the ground,

wherein a respective one of the on-board control units:

is installed in each of the trains,

sets a driving path for the train provided with the on-board control unit based on a destination,

makes a route request for a route to turn back when the driving path is set in which the train provided with the on-board control unit performs a turning-back driving,

makes a route request for a branch route leading to the route to turn back when the route request for the route to turn back is made,

transmits information on the route requests to the on-ground control unit, and

controls driving of the train provided with the on-board control unit on the set driving path based on a traveling position and a traveling speed detected in the train provided with the on-board control unit, and

wherein the on-ground control unit:

controls a route of the train provided with the on-board control unit based on the transmitted information on the route requests.

2. The traffic control system according to claim 1 ,

wherein, when the train provided with the on-board control unit passes the branch route, the on-board control unit maintains the route request for the branch route for a predetermined period, and then, cancels the route request for the branch route.
