THE IDENTIFICATION AND CORRECTION OF CONFLICTS IN TRAIN RUNNING CONTROL

An on-line decision making program run off on a process computer for space and time reasons cannot in all cases produce optimum decisions. The intention is to solve satisfactorily as high as possible a percentage of conflict situations encountered by the application of simple and manageable decision making rules. In the remaining decisions to be taken by the controller he is assisted by computer prepared decision aids in the form of tables and graphs. The program described here consists of several modules, the first of which relates to a route traffic control system intended to be further developed parallel to practical testing. The control process is initiated in cycles and when special events occur (e.g. track closure). After each start, the timetables are generally compiled in advance for all trains, covering almost the next half hour (block sections and occupation times). The controller is advised of all conflict situations and how they can be corrected. Decisions by the controller override computer decisions.
