2023 South Carolina Primary and Secondary Road Network

A 2023 TIGER/Line shapefile from the U.S. Census Bureau containing primary and secondary road features for the state of South Carolina. The data is extracted from the national Master Address File/Topologically Integrated Geographic Encoding and Referencing (MAF/TIGER) Database, which provides a seamless, non-overlapping geographic base. It includes roads classified by the MAF/TIGER Feature Classification Codes S1100 for primary roads and S1200 for secondary roads.

Use Cases

• Calculate road network density and connectivity metrics using the linear feature geometry for transportation planning.
• Analyze the spatial distribution of primary roads (MTFCC S1100) versus secondary roads (MTFCC S1200) across South Carolina counties.
• Integrate road centerlines with address range data for geocoding applications within the state.
• Perform network analysis for routing by leveraging the topological integrity of the TIGER/Line road segments.

Strengths

• Data originates from the authoritative U.S. Census Bureau MAF/TIGER Database, ensuring national consistency.
• Roads are classified with specific MAF/TIGER Feature Classification Codes (S1100, S1200) for clear feature identification.
• The underlying database is designed as a seamless national file with no overlaps or gaps between geographic parts.

Limitations

• The dataset is limited to primary and secondary roads, excluding local streets and other road types.
• Attribute details beyond basic feature classification and geometry are not described in the provided input.
• Data is specific to the year 2023 and the state of South Carolina, limiting temporal and geographic scope.
