Road Network Shapefile for Sacramento County

All roads and paths in Sacramento County, California, extracted from the U.S. Census Bureau's national TIGER/Line database. The data includes primary roads, city streets, alleys, bike paths, walkways, and stairways, forming a seamless, topologically integrated geographic layer. It is part of a national series designed to stand alone or be combined for broader coverage.

Use Cases

• Analyze road network density and connectivity using the MTFCC feature classification codes for different road types.
• Create basemaps for urban planning by integrating features like vehicular trails, ramps, and service drives.
• Perform spatial joins for address geocoding using the linear road features and associated address range attributes.
• Model pedestrian and bicycle accessibility by identifying features classified as bike paths, walkways, and stairways.

Strengths

• Data is part of the U.S. Census Bureau's national Master Address File/TIGER System, ensuring topological consistency with no overlaps or gaps.
• Includes a wide variety of road and path features, from primary highways to private service roads and pedestrian stairways.
• Shapefile is designed to be used independently for county-level analysis or combined seamlessly to cover the entire United States.

Limitations

• Specific metrics like total road length, row count, or feature counts are not provided in the input.
• The description does not specify the vintage or year of the road data extract, which is critical for temporal accuracy.
• Lack of sample data or column schema makes preliminary assessment of attribute completeness difficult.
