Project Description

Summary:  View help for Summary
This dataset contains measures of primary and secondary roads (highways and main arteries) per United States ZIP code tabulation area (ZCTA) in 2010. These measures may be used as a proxy for heavy traffic, high traffic speeds, and impediments to walking or biking. Variables include: counts of primary, secondary, and all streets per ZCTA; total length of primary, secondary, and all streets per ZCTA; ratio of primary and/or secondary road counts to all roads; and ratio of length of primary/secondary roads to all roads.

A curated version of this data is available through ICPSR at https://doi.org/10.3886/ICPSR38585.v2

Sample code for merging the UDS Mapper crosswalk with NaNDA datasets is available on the NaNDA repository at https://www.openicpsr.org/openicpsr/project/120088/.

Methodology

Data Source:  View help for Data Source Data on road types, lengths, and census block is taken from the U. S. Census Bureau’s TIGER/Line shapefiles, specifically the All Lines and Topological Faces shapefiles for 2010 census geography. We used data from the geographic header files of the 2010 decennial census to map census blocks to ZCTAs.
