A system is disclosed for identifying the location of a vehicle (11), assembling data related to vehicle performance and correlating the assembled data with vehicle location. From the correlation of data and location, a data base is generated that provides information for monitoring performance of the vehicle (11), reporting irregularities in the performance and generating control signals for commanding vehicle movement. The system comprises a plurality of signposts (180) located at intended destinations of a vehicle (11), wherein each signpost (180) is characterized by indicia that are distinctive to the associated destination. On board each vehicle (11) is a device (198) for detecting a signpost when the vehicle is within a predetermined proximity of it. The device generates data indicative of the location of the vehicle in response to detection of a signpost (180). Also on board each vehicle are sensors (49,102,105,107,109,110,116) for collecting and recording data indicative of vehicle performance. The location and performance data are correlated to provide a data base for use by a computer in monitoring the vehicle performance, reporting irregularities in the performance and locating the vehicle and controlling the movement of the vehicle. |
