At a time when funds for new roads are declining due to smaller tax bases and competition for funds from other public sectors, the attractiveness of high technology to provide information and improve traffic management is increasing. This paper reports on the public transport selective vehicle priority capabilities of the scat traffic signal linking system and explores the technological issues related to the development of a vehicle monitoring system based on the integration of in vehicle intelligence and sensory equipment in the road bed. It is concluded that recent developments in technology now provide realistic opportunities to extend the classical functions of urban traffic signal systems to assist the community and traffic manager.
