The purpose is to explore, develop, and guide design of traffic environment and vehicles in order for the road user to directly and automatically make correct and safe decisions. Primarily this applies to the environment around the road users and vehicles, but it also applies to the design of vehicles as interfaces. Traffic environments and vehicles should be designed such that the road users spontaneously make correct decisions, so the risk of human error is minimized.

The project will explore how traffic environments and vehicle design can be improved with regard to this. For example, the need for road signs and markings should be decreased, in order to minimize risks of contradictive information and resulting errors. A manual for road keepers ought to be made, such that they can check and improve traffic environments. We also intend to investigate and develop methods to improve road users' spontaneous awareness about own speed and position, such that for instance fuel consumption decreases and distance to other vehicles becomes more constant, by providing intuitive interfaces as complements to existing standard iconic interfaces with digits and dials.

The major part of the research is conducted as experiments in vehicle simulators, but also as field experiments on road, in vehicles equipped with prototypes of new driver interfaces.
