Road Network Buffers for Motorways and 2-Lane Roads in France

A 2021 geospatial dataset from the DREAL Hauts-de-France region, sourced from the Carto BD database. It contains buffer zones of 100 meters around motorways and 75 meters around national and departmental 2-lane roads. The data was produced by the Bureau de Recherches Géologiques et Minières.

Use Cases

• Modeling noise pollution zones based on road type and buffer distance.
• Assessing land use constraints for construction near major roadways based on defined buffer zones.
• Planning green infrastructure or safety corridors adjacent to transportation networks.
• Analyzing potential environmental exposure areas related to road traffic.

Strengths

• Specific buffer distances are defined: 100 meters for motorways and 75 meters for other roads.
• Data originates from the authoritative Carto BD database for France.
• Dataset has a precise last update date of 2021-04-30.

Limitations

• Column-level documentation is absent; field semantics must be inferred after download.
• Row count is unknown, which may limit suitability assessment.
• Last updated 2021-04-30; freshness should be verified for current applications.
