Melbourne Road Surface Polygons With Condition Ratings

Polygon data from the City of Melbourne details road surface types like carriageway, footpath, and tramway. Each record includes material, installation date, area, length, width, and a visual condition rating from 1 (failed) to 5 (good). The geometry is stored as Well Known Text (WKT).

Use Cases

• Predict asset condition ratings from material, instaldate, and area_sqm using regression models.
• Analyze the distribution of surface types (carriageway, footpath, median) by material and length to prioritize maintenance.
• Calculate total area_sqm and length of footpath and tramway surfaces for accessibility and infrastructure planning.
• Spatially join the_geom polygons with other datasets using the assetno identifier for network analysis.

Strengths

• Includes a standardized visual condition rating (1 to 5) for each asset.
• Contains seven distinct surface type categories, such as carriageway, footpath, and tramway.
• Provides multiple geometric and dimensional attributes: area_sqm, length, width, and the_geom.

Limitations

• Unknown row count prevents assessment of dataset scale and statistical power.
• Lacks explicit temporal range for instaldate, limiting trend analysis over time.
• Geographic scope is limited to the City of Melbourne, not representative of other regions.
