Ohio Primary and Secondary Road Network from 2023 TIGER/Line

Ohio's 2023 primary and secondary road network is provided by the U.S. Census Bureau as a TIGER/Line Shapefile extract. This dataset includes roads classified as primary divided highways (MTFCC S1100) and secondary main arteries (MTFCC S1200). It is part of a seamless national geographic database designed to be used independently or combined for broader coverage.

Use Cases

• Analyze the spatial distribution and connectivity of primary roads (MTFCC S1100) for statewide transportation planning.
• Map secondary road features (MTFCC S1200) with local names and route numbers for geocoding or address matching applications.
• Integrate Ohio's road network with other TIGER/Line shapefiles to create a multi-state regional transportation model.
• Perform network analysis on road segments to calculate travel distances or identify critical infrastructure links.

Strengths

• Data originates from the authoritative U.S. Census Bureau MAF/TIGER Database (MTDB), ensuring national consistency.
• Roads are topologically integrated with no overlaps or gaps, supporting accurate spatial analysis.
• Includes specific feature classification codes (MTFCC S1100 and S1200) for precise identification of primary and secondary roads.

Limitations

• The dataset is limited to Ohio, requiring combination with other state files for national analysis.
• Specific counts of road segments (rows) or attribute columns are not provided in the input.
• The 2023 data may not reflect recent road construction, closures, or name changes.
