An automatic mobile speed violation detection and response system for identifying vehicles traveling in excess of a predetermined speed and providing a response to this violation is proposed. The mobile speed violation detection device includes: measurement of target vehicle speed and outputting signal indicative of the measured speed; capturing license plate data on the RF ID tag affixed to the target vehicle when vehicle exceeds the predetermined speed; identifying the location of the speed violating vehicle; tagging the captured RF ID based license plate data with vehicle speed and location data; wireless communication of transmitting speed, license plate data, location data and local speed limit to and from the information system. This system is designed to monitor and control the speed of vehicles through wireless network. Zigbee is used for wireless communication in th...
