Projected impact on security of driving-aid systems, based on known and simplified motorway security models.

This article briefly describes the accident reducing potential of the PROMETHEUS programme. Data about motorway accidents are presented first. This is followed by a brief description of the various ATT (Advanced Traffic Telematics) systems within the PROMETHEUS programme. These include: a) the provision of traffic information by RDS-TMC (Radio Data System - Traffic Message Channel); b) proximity information; c) route guidance; d) autonomous intelligent cruise control; e) vehicle lateral positioning; and f) emergency warning transmission. A forecast of the percentage of accidents prevented by each system is provided.
