Multiple driver support systems and traffic safety. On behalf of the Ministry of Transport and Public Works, Transport and Traffic Research Division AVV.

This aim of this project is to investigate the effects of various applications of Advanced Traffic Telematics (ATT systems) on road safety. Although many of these systems are intended to make driving easier or safer, they can also change or extend the driver's task in such a way that safety is impaired. The project aims to develop a checklist and a test-bed for structured field testing in order to assess the adverse safety effects. The general conclusion is that there are many possible combinations of properties of commonly conceived ATT systems that cause potentially unacceptable interference with the driving task and only few conditions where combined actions may be considered acceptable. Either completely integrated systems or a type of GIDS-like `interrupt handler' will be required to avoid unacceptable interference.
