This study describes a pilot project for a classification system of the road network in the Dutch municipality of Nijmegen. The project was based on the 'sustainably safe road traffic' approach. The main purpose of this approach is to develop a road traffic system which takes maximum possible account of both the possibilities and limitations associated with road users. An important component in achieving a 'sustainably safe road traffic' system is to apply a classification system on the road network in order to ensure an optimum coordination of its function, design and use. The first step undertaken was to make a broad classification of the whole of the Nijmegen road network. This classification was finalised using the 'monofunctional model'. This model assigns one function only to through roads, distributor roads, and access roads. Subsequently, the classified Nijmegen road network was tested in its existing form against the most important design requirements. The test includes both the three road categories and intersections.
