Impact of in-car traffic information

The most basic form of in-car navigation has proven to be a good application to guide travellers to their destination. These devices know the position of the traveller and lead them to their destinations. By adding traffic information to these static systems they become dynamic. Therefore it is much more complex to determine the effects on traffic. It is yet unknown what will be the consequences when more and more people start using these dynamic systems. As these dynamic systems can never tell the users exactly which traffic state they will encounter, it may have negative influence on the advices they provide. Moreover it is rather unclear how travellers will react when such systems do not provide perfect advices. The aim of this study is to get a better insight in the interaction between users and information in case of an increasing market of in-car traffic information and see whether this has consequences for Rijkswaterstaat as the road authority.
