Shawinigan Road Centerline Network with Attributes

A polyline layer representing the road network drawn at the center of each lane within the city of Shawinigan, Canada. The dataset was created from AutoCAD digital files by the Government and Municipalities of Québec and was last updated in April 2026. It includes attributes for street names, functional classification, construction years, traffic details, and physical dimensions.

Use Cases

• Calculate road segment lengths and areas using the `st_length (shape)` and `area_m2` columns for infrastructure asset valuation.
• Analyze traffic flow and road hierarchy by joining the `functional classification`, `unique_sense`, and `speed` attributes with network analysis tools.
• Model road maintenance schedules by examining construction and resurfacing history in columns like `annee_origine`, `annee_reconstruction`, and `annee_resurfacage`.
• Perform geocoding and address matching using the various street name fields (`street_toponymie`, `partial_street`) and civic number columns (`nocivicpairde`, `nocicivicpaira`).
• Assess road physical characteristics for planning by analyzing `width_m`, `nbre_voies` (number of lanes), `typesurface`, and drainage attributes.

Strengths

• Contains over 40 detailed attributes per road segment, including construction history and physical properties.
• Spatial data is explicitly drawn as center-lines for accurate network representation.
• Published under a permissive CC-BY-4.0 license for broad reuse.

Limitations

• The total number of road segments (rows) and geographic file size are unknown.
• Contains numerous untranslated French field names and values (e.g., `de`, `a`, `vocation`), which may require translation for English-centric workflows.
• Temporal coverage for the underlying road data is unclear, relying on estimated year fields.
