PanelMarkings is a geospatial dataset from the City of Seattle's SDOT Transportation account, representing roadway paint lines, curbs, and other markings that delineate traffic lanes, bike routes, and bus zones. The data is part of a larger channelization layer and is updated dynamically via AutoCAD. It was last updated on 2026-03-22.
Use Cases
- Modeling traffic lane configurations based on longitudinal and transverse markings data.
- Planning bicycle and bus route infrastructure based on delineated bike routes and bus zones.
- Conducting public safety audits of roadway channelization elements like curbs and panel markings.
- Creating base maps for transportation planning using the layered channelization data structure.
Strengths
- Data is part of a structured channelization system with seven specific layers, including lane widths and symbols.
- Update cycle is dynamic via AutoCAD, suggesting potential for near-real-time accuracy.
- Published by the authoritative City of Seattle SDOT Transportation account.
Limitations
- Row count and dataset size are unknown, which may limit suitability assessment.
- Column-level documentation is absent; field semantics must be inferred after download.
- Description metadata is limited; actual data quality requires manual inspection after download.
