The crash rate on a heavily traveled two-lane rural highway is abnormally high. Thecorridor is 14 miles long with an ADT of 34,000. An investigation has determined thathead-on collisions are most common with an RMVMT of 4.5 and are caused by vehicles attempting to pass. Determine an appropriate countermeasure and calculate theestimated yearly reduction in total crashes.
