Road characteristics database-WKD / Road categorization
Description
The road attribute database is a collection of databases each with a relevant road attribute
which can be linked to the national road register (NWB). This can be road characteristics
are such as, for example, the maximum speed, the width of the road or the presence of entries.
A separate file is available for each of these road characteristics.
This road characteristics database displays the road widths of all roads in the NWB.
The median width, the minimum width and the minimum width are indicated per NWB road section.
maximum width. The median of the width of the road represents the width
Most of the road section is also the actual width. There is also in the file
indicate whether there is a narrowing sign on the road section and whether there is also narrowing
is present.
The road width of a road section is determined with the Large-Scale Topography Basic Registration.
(BGT). This applies to all roads except the national roads. This also means that the width is
determined from side to side and that concerns the entire width of the paving surface of the road.
For the national roads, the width is determined by the Digital Topographic File (DTB) of
Rijkswaterstaat to be used. The width that is determined for the national roads is the width between
the paint lines. This means that, for example, flight lanes and repair lanes do not reach the
road width is calculated.
The road narrowings and the corresponding traffic signs have been taken from the
traffic sign file made available at NDW.
Refurbishment WKD Road characteristics
In the coming period, the road characteristics will be redesigned with the aim of more compact and uniform recording of data. This removes certain technical columns, such as NWB_version and Roadbox start date, due to their redundancy or lack of added value.
The following WKD attributes will be updated:
• Axle load restrictions
• Height restrictions
• Burden restrictions
• Length restrictions
• School zone
• Traffic types
• Road width
• Road categorisation
• Road narrowings
Both variants of the custom data will be available next month on the usual platforms.
Adjustments to WKD files
In addition, in all WKD files, the Start Date and WVK_ID columns are inverted for uniform identification. This change will be implemented in autumn 2024.
