NWB Roads route system National roads and Provincial roads, segmentation mode A, route5 (RWS)

The NWB Roads is a digital geographical file of all roads in the Netherlands. All roads managed by road managers such as the State, provinces, municipalities and water authorities are included, however, only to the extent that they have a street name or number. So also loose foot and cycle paths and unpaved roads, if marked with a street name, are included in the NWB Roads. If a road has separate lanes, which is especially the case with Rijkswegen, they are processed as separate sections in the file. The NWB Roads file currently consists of more than 158,000 hectops and more than 1 million digitised road sections with a total length of nearly 158,000 kilometres (measurement 2020). However, all the national and provincial roads are included in this derived product. It is possible to segment the route system based on information present in entities below the road section. There are two possible variants: A: hectointervals: B: combination of hectointervals and hectopoint positions. The difference between the two variants is that variant A assumes the situation in which hectometer poles on a road section are at equal distances from each other. In practice, this is not the case. That is why variant B has been developed. In this variant, each segment is formed by the positions of the hectopoints, combined with hectometration of hectosprongen and junctions of road sections (i.e. the hectointervals). Because the user will want to display the network at different levels, five different route systems are provided. The NWB_wegen_route product is updated monthly. More information and news about the NWB can be found at https://nationaalwegenbestand.nl/ Representatives of municipalities, provinces, water authorities and Rijkswaterstaat have started to design and organise the cooperation on the NWB. In the context of this further development of the NWB, we are happy to get in touch with you, the NWB user. We therefore ask you to send an email with your contact details to the following address: [email protected]
