<p>A system and method for monitoring and reporting out-of-route mileage for long haul trucks includes transmitting route data from a dispatcher to a distant truck where comparisons aboard the truck are made of its current position with predetermined acceptable positions and exception reports are generated and transmitted back to the dispatcher from the truck if the current position is not included in the set of predetermined acceptable positions. The truck has on board a transceiver computer assembly 204 with a program memory assembly 206. The transceiver computer assembly 204 includes an input 232 for a position source which may be a GPS receiver for providing a report on the truck position, and an input 230 for an auxiliary data source which may be an on-board mileage counter. Geographic co-ordinates representing route segment end points are also input and the processor 210 computes a set of acceptable positions for the truck. <IMAGE></p> |
