The system analyzes the data and recognizes if a dangerous situation exists such as the sudden appearance of road construction sites, traffic back-ups and warnings of objects on the road or inclement weather. Drivers are warned of the precise location of the danger through warning lights integrated in the reflector posts and directly via car-to-x communication. Fraunhofer Institute for Embedded...

A simulator system to predict and hear road traffic noise was developed. The system places sound sources on vehicles in traffic flow simulation and reproduces sound data by using a three-dimensional sound capability. By using this system, the effect of road construction work and that of sound barriers as a countermeasure can be presented as easily-understood information; this capability should ...
