Multiple driver support systems and traffic safety

This project is aimed at investigating the effecvts on road safety of various applications of Advanced Traffic Telematics (ATT systems) intended to support the driver in different aspects of the driving task (e.g. by date route information, maintaining a constant speed and headway, adaptation to the local speed limit, prevention of collisions). Although many of those support systems are intended to make driving easier or safer, they can also change or extend the driver's tasks in such a way that safety is impaired. In this report the characteristics of support systems are given and the possible consequences of two simultaneous messages or actions by different systems are analysed. Finally, a checklist is made for the assessment of system interference and possible adverse safety effects.
