LOCATION AND/OR DIRECTION OF TRAVEL DETECTION SYSTEM AND METHOD
First Claim
1. A method comprising:
- obtaining location data from wayside devices, the location data representative of locations of the wayside devices along a route being traveled by a vehicle;
determining 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, determining one or more of a direction of travel of the vehicle along the route or a location of the vehicle along the route.

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.

9. A system comprising:
-
a tag reader device configured to obtain location data from wayside devices, the location data representative of locations of the wayside devices along a route being traveled by a vehicle; and a controller configured to 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, to determine a direction of travel of the vehicle along the route. - View Dependent Claims (10, 11, 12, 13, 14, 15, 16)

17. A method comprising:
-
obtaining location data from radio frequency identification tags disposed at different locations along a route, the location data representative of the locations of the tags along the route from a designated location; determining whether the location data in a series of at least three neighboring tags of the tags includes a sequential increase or a sequential decrease in the location data across the at least three neighboring tags; and responsive to determining that the location data across the at least three neighboring tags does not include the sequential increase or the sequential decrease in the location data, identifying one or more of the at least three neighboring tags as a misplaced tag. - View Dependent Claims (18, 19, 20)
