Abstract:
A system and method for determining a direction of travel of a vehicle and/or identifying a misplaced wayside device obtain location data from wayside devices. The location data are representative of locations of the wayside devices along a route being traveled by a vehicle. The system and method also determine whether the location data in a series of the wayside devices exhibit an increase or a decrease in the location data across the wayside devices in the series and, responsive to determining whether the location data in the series of the wayside devices does exhibit the increase or the decrease in the location data, the system and method determine a direction of travel of the vehicle along the route, determine a location of the vehicle along the route, and/or identify a misplaced wayside device.
