First Claim
Patent Images
1. A method comprising:
- receiving one or more absolute times associated with movement of a vehicle system, the one or more absolute times communicated from the vehicle system to notify of at least one of an arrival or departure of the vehicle system at a crossing between a first route being traveled by the vehicle system and a second route;
modifying at least one of the one or more absolute times into a first relative time; and
controlling one or more warning devices using the first relative time, the one or more warning devices controlled to at least one of notify one or more other vehicles traveling along the second route of the at least one of arrival or departure of the vehicle system at the crossing or prevent the one or more other vehicles from traveling through the crossing along the second route.

Abstract
A method includes receiving an absolute time associated with movement of a vehicle system, modifying the absolute time into a relative time, and controlling one or more warning devices using the relative time. A system includes a crossing module configured to receive an absolute time associated with movement of a vehicle system. The crossing module is configured to modify the absolute time into a relative time and to control one or more warning devices using the relative time.

18. A system comprising:
-
a crossing module that includes one or more computer processors configured to receive an absolute time associated with movement of a first vehicle system along a first route toward a crossing between the first route and a second route, the absolute time representing at least one of an arrival time of the first vehicle system at the crossing or a departure time at which the vehicle system is expected to complete passage through the crossing, wherein the crossing module is configured to modify the absolute time into a relative time; and one or more warning devices including at least one of a gate or a light, wherein the crossing module is configured to at least one of;
activate the gate upon expiration of the relative time to prevent passage of one or more other vehicles through the crossing along the second route, activate the light upon expiration of the relative time to notify the one or more other vehicles of arrival of the first vehicle system at the crossing, or activate the gate to prevent the one or more other vehicles from passing through the crossing along the second route until the relative time indicates that the first vehicle system has completed passage through the crossing along the first route. - View Dependent Claims (19, 20)
