Abstract
One of the targets of the Dutch traffic and transport policy is a `sustainably safe' road network. In this respect it is essential that the road user is fully aware of how he should behave in the different sorts of traffic environments and which behaviour he can expect from the other road users. The road infrastructure should stimulate the right behaviour by giving sufficient and consistent information. ln this way the road user can predict the sort of situations he will meet. Road designers and urban planners should choose the appropriate sort of infrastructural elements for each traffic environment. (A)
