Abstract: A signal aspect enforcement method for a rail vehicle includes determining, by an on-board controller on the rail vehicle, a position of the rail vehicle; determining, by the on-board controller, whether a first signal aspect for a signal matches a second signal aspect for the signal; and determining, by the on-board controller, at least one of a route of the rail vehicle or a speed limit of the rail vehicle when the first signal aspect matches the second signal aspect. The first signal aspect is determined from first data from first system on the rail vehicle, and the second signal aspect is determined from second data from a second system on the rail vehicle, which system is different from the first system used to determine the first signal aspect.
