New Mexico Primary and Secondary Roads from 2023 TIGER/Line

New Mexico's 2023 primary and secondary road network from the U.S. Census Bureau's TIGER/Line database. The dataset provides a seamless, topologically integrated extract of road features, including MAF/TIGER Feature Classification Codes (MTFCC) like S1100 for primary roads and S1200 for secondary roads. It is designed to stand alone for the state or be combined with other files for national coverage.

Use Cases

• Analyze the spatial distribution and connectivity of primary roads (MTFCC S1100) versus secondary roads (MTFCC S1200) across New Mexico.
• Integrate road centerlines with address range data for geocoding applications within the state.
• Perform network analysis on the road system using the topologically integrated, seamless geometry from the Master Address File/TIGER Database (MTDB).

Strengths

• Data is derived from the authoritative U.S. Census Bureau Master Address File/TIGER Database (MTDB), ensuring national consistency.
• The MTDB provides a seamless national file with no overlaps or gaps, and this state extract is designed to be topologically integrated.
• Roads are classified with specific MAF/TIGER Feature Classification Codes (MTFCCs), such as S1100 for primary and S1200 for secondary roads.

Limitations

• The dataset lacks specific quantitative details such as total road segment count, length, or number of attributes.
• As a 2023 extract, it may not reflect recent road construction, closures, or changes in the New Mexico transportation network.
• The description does not specify the level of detail for attributes like speed limits, traffic volume, or pavement condition.
