Pennsylvania Primary and Secondary Roads from 2023 TIGER/Line

U.S. Census Bureau's TIGER/Line shapefile provides geographic and cartographic data for Pennsylvania's road network. The dataset includes primary roads, which are limited-access highways like interstates, and secondary roads, which are main arteries like U.S. and State highways. Each road type is distinguished by a specific MAF/TIGER Feature Classification Code (MTFCC).

Use Cases

• Analyze the spatial distribution of primary roads (MTFCC S1100) versus secondary roads (MTFCC S1200) across Pennsylvania for transportation planning.
• Integrate road geometry with address range data to support geocoding applications within Pennsylvania.
• Use the linear feature data to calculate road density or network connectivity metrics for specific counties or regions in Pennsylvania.

Strengths

• Data is extracted from the Census Bureau's national Master Address File/TIGER Database, ensuring topological consistency with no overlaps or gaps.
• Roads are classified with specific MAF/TIGER Feature Classification Codes (S1100 for primary, S1200 for secondary) for clear categorization.
• The dataset is part of the 2023 TIGER/Line series, providing a recent snapshot of Pennsylvania's road infrastructure.

Limitations

• The dataset is limited to Pennsylvania and primary/secondary roads, excluding local streets and other road types.
• Sample data and specific record counts (rows) are unavailable, making it difficult to assess the dataset's granularity and scale prior to download.
