Samenvatting
An accident analysis has been made after the installation of an fog warning and fog detection system on the A16 motorway. Complicated accidents have not occurred after the installation and the number of other accidents have decreased, in particular the rear-end collisions. Other kinds of accidents during fog can be decreased as far as the lower speed adds to the prevention of skidding due to a slippery road. Besides the installation of the fog warning and fog detection system eventual side effects have been studied such as coupling with the Automatic Incident Detection System and the installation of another street lighting.
