NWB: National Road Network of the Netherlands with Manager Contact Data

Over 1.1 million digitized road sections covering more than 160,000 kilometers of streets in the Netherlands, as measured in January 2022. The dataset is produced by the Ministry of the Interior and Kingdom Relations and includes all roads managed by national, provincial, municipal, and water board authorities, provided they have a street name or number. The NWB Roads file is updated monthly.

Use Cases

• Mapping and visualizing the national road network based on the detailed geospatial road sections.
• Analyzing road administration by linking road segments to their managing authority and contact information.
• Calculating total road length and density for different regions or administrative levels.
• Developing routing or navigation applications using a comprehensive, officially managed road graph.

Strengths

• Includes over 1.1 million individual road segments, providing high granularity.
• Covers more than 160,000 kilometers of roads across the Netherlands.
• Updated monthly, suggesting relatively current data.
• Includes unpaved roads, footpaths, and cycle paths if they have a street name, offering broad coverage.

Limitations

• Column-level documentation is absent; field semantics must be inferred after download.
• Row count is unknown, which may limit suitability assessment for specific analytical needs.
• Data may reflect geographic bias inherent to its source, being limited to the Netherlands.
