California Primary and Secondary Road Network from 2022 TIGER/Line

A 2022 extract from the U.S. Census Bureau's MAF/TIGER Database details California's primary and secondary road infrastructure. The dataset provides a seamless, topologically correct representation of major state highways and main arteries, distinguished by MAF/TIGER Feature Classification Codes (MTFCC). It is designed to stand alone for California or be combined with other state files for national coverage.

Use Cases

• Map primary roads (MTFCC S1100) and secondary roads (MTFCC S1200) for statewide transportation network analysis.
• Perform spatial analysis on road density and connectivity using the topologically integrated geographic encoding.
• Combine this California shapefile with other state TIGER/Line files to create a seamless national road network dataset.
• Validate address ranges and linear features against the authoritative MAF/TIGER Database for California.

Strengths

• Data originates from the authoritative U.S. Census Bureau MAF/TIGER Database, ensuring national consistency.
• The dataset is topologically integrated, representing a seamless file with no overlaps or gaps for its defined geographic area.
• Roads are precisely classified using MAF/TIGER Feature Classification Codes (MTFCC S1100 for primary, S1200 for secondary).

Limitations

• The dataset is limited to 2022, so it does not reflect road network changes, construction, or closures after that year.
• It contains only primary and secondary roads, excluding local streets, trails, and other minor transportation features.
• As a shapefile extract, it may require GIS software for full utilization and lacks the complete attribute detail of the full MAF/TIGER Database.
