The N.C. Department of Transportation's Traffic Survey Group collects traffic data statewide to analyze and support planning, design, construction, maintenance, operation and research activities required to manage North Carolina's transportation system.

The data is summarized in annual average daily traffic (AADT) volume maps that present the traffic average for a specific year at specific points on the state's roads. Data is collected at thousands of locations throughout North Carolina using portable traffic count stations.

Except for locations within 18 urban areas across the state, the maps are published every year. Roadways in urban areas are published every other year.

Interactive Traffic Volume Map

NCDOT uses an interactive mapping tool, called ArcGIS, to present annual average daily traffic volume since 2002. Users can view information based on an address and zoom in or out and pan in any direction. (Learn about more features.)

Data presented in the interactive map can also be downloaded (in ArcGIS format) and viewed using ArcView or ArcMap software.

Disclaimer

Data in the maps shapefiles was digitized referencing the available NCDOT GIS Data Layer, LRS Arcs Shapefile Format from Quarter 1 release and is not the result of using GPS equipment in the field. NCDOT shall not be held liable for any errors in this data. This includes errors of omission, commission, errors concerning the content of data and relative positional accuracy of the data. This data cannot be construed to be a legal document.

Urban-Area Traffic Volume Maps

Annual average daily traffic AADT volume maps for North Carolina's 18 major urbanized areas are collected on a two-year cycle, with eight collected in the even-year cycle and 10 in the odd-year cycle.


County–Area Traffic Volume Maps (by Year)

For county maps, the name of the county will be followed by a number, which represents each sheet (e.g., sheet 2 of 9). If you do not know which sheet you need, click on the "sheet key." If a sheet key is not available, you can always find it on the first sheet for each county.

Notes:

  • Not all roads have portable traffic count stations located on them.
  • Except for interstate, N.C. and U.S. routes, NCDOT county maps refer to roads using a four-digit secondary road number, not a road's local name.
  • To locate a secondary road number and/or name of a road, use NCDOT's Secondary Roads Database, which provides a cross-index of road names and secondary road numbers.
