Centerline miles represent the total length of a given road from its starting point to its end point. The number and size of the lanes on that road are ignored when calculating its centerline mileage.
Our technology can collect and assess the lane the vehicle is driving in plus one lane to the left and one lane to the right.
As long as the view of the road is not obscured by a barrier or wider than 3 lanes, we can assess the road with one pass.
Generally, our definition of a centerline mile fits in well with what a municipality defines as one.
