Abstract
An innovative speed enforcement system has been developed by Autostrade per l'Italia and progressively deployed along the Italian toll motorway network. The national Traffic Police operates the system scheme and processes, including the validation and issuing of speed tickets. The enforcement system is based on the measurement of the average speed of vehicles traveling along a road section. The speed control is accomplished through sets ofinstallations that make use of existing roadside infrastructure for investment optimization purposes. Safety Tutor is part of an integrated enforcement system which allows the detection of violations along the national high speed road facilities.
