Select the desired county from the drop down menu above the map of Tennessee.  Zoom in with the plus and minus feature to locate the area where you need a count.  The panning feature (hand) will appear automatically.  The red dots are the count stations.  Position the panning hand on the red dot so that it has a pointing finger.  Left click on the dot and the ADT counts will appear on the right side of your screen.
