Traffic control device transmitter, receiver, relay and display system

Abstract

A traffic control device information display system. This system includes a receiver that receives information from a traffic control device transmitter for a traffic control device, a processor that processes the information to determine identification information and location information for the traffic control device, and a display that displays the identification information and the location information to an operator. The display highlights traffic control devices for which an error is detected in the location information. This error could be, for example, a reported location that does not match a proper location or a missing reported location, thereby indicating that the traffic control device may have been improperly moved or knocked down. The system can be provided in a vehicle or in a central office.
