Parking Zones in Washington DC Derived from Sign Data

Parking zones created from collected sign data throughout Washington DC. The dataset is published by the District of Columbia and was last updated on March 25, 2026. Zones are defined between two parking restriction signs of the same type that point at each other, or between a sign and an intersection.

Use Cases

• Model parking availability based on sign-derived zone boundaries.
• Analyze parking regulation patterns based on the described sign-to-sign or sign-to-intersection methodology.
• Integrate zone data into transportation or urban planning applications based on the geospatial formats available.

Strengths

• Data is available in multiple geospatial formats, including GeoJSON, KML, and via an ArcGIS REST API.
• Has a clear Creative Commons Attribution 4.0 license (CC-BY-4.0).
• The description provides a specific methodological rule for how zones are created from signs.

Limitations

• Column-level documentation is absent; field semantics must be inferred after download.
• Row count is unknown, which may limit suitability assessment.
• Description metadata is limited; actual data quality requires manual inspection after download.
