System for tracking vehicle speed violations

Abstract

A system for detecting vehicle speed violations is disclosed. The system takes advantage of a vehicle's on-board equipment to track the vehicle speed and position. The speed of the vehicle can be determined in one of two ways. For example, the vehicle speed can be determined by measuring the distance between two points traveled by the vehicle and the time it took the vehicle to travel between the two points. This method relies on a vehicle GPS system and determines the speed of the vehicle by dividing the distance by the time. These GPS co-ordinates are sent to a central database by way of the vehicle on-board computer system and cellular phone system along with a vehicle ID and the date and time. Alternatively, the system can rely on the on-board vehicle speed sensor to transmit the vehicle speed and GPS coordinates along with the vehicle ID, date and time to a central database by way of the vehicle on-board computer and cellular phone system. The vehicle speed and location is system compared with posted speed limits by road segments. If the vehicle is found to be exceeding a posted speed limit, a central server prepares a citation and issues it to the vehicle owner.
