Project Description

Summary:  View help for Summary This dataset contains measures of traffic volume per ZIP code tabulation area (ZCTA) in the United States from 1963 to 2019 (primarily 1997 to 2019). High traffic volume may be used as a proxy for heavy traffic, high traffic speeds, and impediments to walking or biking. The dataset contains measures of the average, maximum, and minimum traffic volume per ZCTA per year. These figures are available for all streets, highways, and non-highways. Because data is collected intermittently across locations over time, traffic volume has been interpolated for years in which no measures are available.

A curated version of this data is available through ICPSR at https://www.icpsr.umich.edu/web/ICPSR/studies/38584/versions/V1

Subject Terms:  View help for Subject Terms traffic; walkability; disamenities
Geographic Coverage:  View help for Geographic Coverage United States
Time Period(s):  View help for Time Period(s) 2010 – 2010
Collection Date(s):  View help for Collection Date(s) 2020 – 2021
Universe:  View help for Universe ZIP code tabulation areas in the United States, excluding U.S. island territories. Note that data is not available for every ZCTA and year because traffic measurements are not available in every year. Measures for missing years are interpolated where possible.
Data Type(s):  View help for Data Type(s) aggregate data
Collection Notes:  View help for Collection Notes A ZIP code to ZCTA crosswalk must be used to combine this dataset with ZIP code geocoded data. Such a crosswalk is available on the UDS Mapper website at https://udsmapper.org/zip-code-to-zcta-crosswalk/. 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 Traffic volume measurements are derived from Kalibrate’s TrafficMetrix database accessed via Esri Demographics. ZCTA boundaries come from the 2019 TIGER/Line shapefiles.
