Abstract
A train traffic control system which automatically prepares a shuttle service diagram based on a partial simulation of each train, at each station, etc., executed only by setting such initial data of the shuttle service as current states of trains in operation and possibility of service extension to other line, that is, other company line, a branch line or the like, when the shuttle service is required in a limited train section due to railroad accident or the like during the traffic control by a normal diagram, and controls the train route according to the shuttle service diagram.
Claims5
A train traffic control, comprising:
- an input device for inputting current data of trains in operation as initial data of a shuttle service at the time of changing the train operation to the shuttle service;
- a file for storing predetermined decision rules including the propriety of approach and departure of the train at each station;
- a simulation means for estimating arrival and departure times of the train by a partial simulation in use of the initial data of the shuttle service at each station within a route operated by the shuttle service:
- means for deciding arrival and departure times of the train at each station according to the simulation result and to the decision rules;
- a diagram preparing means for preparing a shuttle service diagram according to the decision result;
- a central processing unit for transmitting the shuttle service diagram to each station;
- and
- a station control device for controlling train routes at the station according to the transmitted shuttle service diagram;
- wherein said diagram preparing means comprises:
- means for judging for each train one of a current stopping station and a position between stations based upon on-track data;
- means for determining whether a train is between two turn-back stations which surround a location of service interruption;
- means for stopping a first train between said turn-back stations at a station nearest to said first train within a preparation time of said shuttle diagram, and for stopping said first train at its current location if said first train cannot be stopped at said nearest station within said preparation time;
- and
- means for setting a state of a second train located outside said two turn-back stations from one of a stopping station or a position between stations other than said turn-back stations.
