Abstract
A dual-process system for the automatic generation of railway route-solution candidates and their concomitant movement authorities includes a central authority server that accepts dispatcher-provided start and end point data and time information and executes two different independent routing processes to provide two independently determined route-solution candidates. The two solutions are compared for consistency and, when consistent, the route with the minimum authority grants is selected as the solution for use by the locomotive or train.
Claims8
A dual-process system for the automatic generation of at least one movement authority solution between a start point and an end point for a locomotive or a train in a rail system, comprising:
- means for accepting dispatcher-provided endpoints and time data in a rail system;
- a stored-program controlled computing device executing two independent and different routing processes to provide two independently determined routing authority candidate solutions;
- means for comparing the two candidate solutions for consistency and, when the two candidate solutions are consistent, designating the route solution with the minimum authority grants as the route solution for use by the locomotive or train.
A dual-process method for the automatic generation of movement authority solutions between a start point and end point for a locomotive or a train in a rail system, comprising:
- accepting dispatcher-provided endpoints and time data in a rail trackway system;
- executing two independent routing processes to provide two independently determined routing authority candidate solutions;
- comparing the two candidate solutions for consistency and, when the two candidate solutions are consistent, designating the route with the minimum authority grants as the solution for use by the locomotive or train.
