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.
In compliance with standards outlined in the Federal Highway Administration Traffic Monitoring Guide, annual average daily traffic volume maps and reports are published annually, once NCDOT has collected data for the entire state and analyzed and processed the entire set.
