arrow Cobb Traffic Counts
Cobb County Department of Transportation collects and maintains a traffic count database for most roads within the County. The Traffic Count Map, launched through the County's Geographic Information Systems (GIS) portal, includes counts taken from the last 3-4 years and is periodically updated. The counts are the Average Daily Traffic (ADT) which is a 24-hour count of vehicles for both directions of travel.
