You might have noticed the black strips crossing area roadways - particularly Parkersburg City streets.
It's all part of a traffic count in the three largest districts of the West Virginia Department of Transportation, including Wood County-based district three.
The data collected in the next couple of days will determine what changes in traffic devices and patterns happen in the next few years.
"If we're looking at adding a turning lane or widening a road, if we're looking at a traffic signal; anything that we might do to a particular roadway, one of the first things we look at is the ADT, or average daily traffic," says Brent Walker, with the West Virginia Department of Transportation.
More than a hundred strips are now determining average daily traffic numbers in the Charleston, Huntington and Parkersburg districts.
Walker says the results should be available by the end of November.
