National Road Database (NWB) and road data

Rijkswaterstaat's National Road Database is the national road network as lines: every road with a street name or number, from motorway to residential street, split into road sections with road authority, municipality and hectometre markers. On 16 October 2026 that was 1,667,080 road sections and 162,114 hectometre points. Plus NWB Waterways (4,825 waterway sections) and Road Data (WEGGEG) with speed limits and lanes on national roads, linked to the road sections. Via PDOK as OGC API, WFS and WMS.

Road sections in the National Road Database by road authority: municipality is the largest part, 92% in October 2026

Breakdown in October 2026: municipality 92%, province 4.3%, national government 1.2%, water authority 1.2%, other authority (ports, forestry service and others) 0.9%. Total: 1,667,080 road sections.

What can you do with it?4 ideas

Getting started

Who manages which road?

The wegbehsrt field tells you: 92% of road sections belong to a municipality, 4.3% to a province, 1.2% to the national government and 1.2% to a water authority. Colour a map of your region by authority.

Getting started

Where can you drive 130?

WEGGEG has the speed limit per road section, with times: 130 from 7 pm to 6 am and lower during the day. On 16 October 2026 it held 7,176 rows with 130 and 10,999 with 100.

Advanced

Accidents and traffic on the map

Much traffic data (NDW, accident records) refers to an NWB road section or hectometre post. Use wvk_id to join them to the road itself.

Advanced

How many kilometres of road per municipality?

Sum the length of the road sections (st_lengthshape, in metres) per municipality and per authority. On dual carriageways each carriageway has its own road sections.

How to process it4 steps

Road sections in a street or municipality
The OGC API can filter on gme_naam, stt_naam, wegbehsrt, wegnummer and wvk_id; at most 1,000 per page, follow the next link.
```
https://api.pdok.nl/rws/nationaal-wegenbestand-wegen/ogc/v1/collections/wegvakken/items?f=json&limit=100&gme_naam=Utrecht&wegbehsrt=R
```
Speed limits on the A2
WEGGEG filters on omschr (the speed) and wvk_id. Join on wvk_id to the road sections for the road number. begintijd and eindtijd give the time window (19 and 6 = evening and night).
```
https://api.pdok.nl/rws/weggegevens/ogc/v1/collections/wegvak_max_snelheden/items?f=json&limit=10&omschr=130
```

Counting with the WFS

The OGC API gives no total. The WFS does, also with a filter. An unfiltered count over all road sections takes about 18 seconds.

Waterways

NWB Waterways has waterway sections with name and number, and kilometre markers (2,886).

Interesting combinations

locatie op het wegvak (wvk_id, hectometrering)

Where is traffic most often at a standstill?

Place the NDW measuring points on the NWB road sections and count per section the minutes below 30 km/h.

Combine with NDW live traffic data

roadSectionId = wvk_id

Which signs stand along which road?

Every traffic sign in the NDW API has a roadSectionId and nwbVersion; that is the wvk_id of the road section in that NWB version.

Combine with Traffic signs and accessibility map (NDW)

OpenStreetMap
OSM also has cycle paths, footpaths and road types and is kept by volunteers; the NWB is the official register of road authorities, with hectometre markers.
NDW live traffic data
Speeds and volumes per measuring point, minute by minute; the NWB is the road network those measurements sit on.
Overture Maps
Global road network from OSM and other sources, without Dutch road authorities or hectometre markers.

What to watch out for

Only roads with a name or number
According to the description, only roads with a street name or road number are in the NWB. Unnamed paths and many cycle paths are missing.
Road sections, not kilometres
A road section runs from junction to junction. Counting them mainly shows how densely the network branches; for length use st_lengthshape.
WEGGEG only for national roads
Speed limits and lanes are only available for national roads. For municipal and provincial roads use the NDW traffic signs.
Ids change between versions
The NWB is released in versions (collection updated on 5 October 2026). Other data sometimes name the version they were built on, such as nwbVersion in the NDW traffic signs (2026-03-01 for the first sign). Join with the same version where possible, and check for wvk_ids that no longer exist.

Limits and pitfalls

At most 1,000 features per request (CountDefault). from the description
Paging supported: count and startIndex (ImplementsResultPaging). from the description
In the WFS fields are named differently from the OGC API: wvkId, sttNaam, gmeNaam (camelCase) versus wvk_id, stt_naam, gme_naam. Filtering on wegbehsrt works in both. tested
WEGGEG has its own WFS (service.pdok.nl/rws/weggegevens/wfs/v1_0) with the layers wegvak_max_snelheden (26,441) and wegvak_rijstroken (22,910). tested
