A vehicle moving at a speed of 50 mph is slowing traffic on a two-lane highway. What passing sight distance is necessary, in order for a passing maneuver to be carried out safely? Calculate the passing sight distance by hand, and then compare it to the values recommended by AASHTO. In your calculations, assume that the following variables have the values given: Passing vehicle driver's perception/reaction time = 2.5 sec. Passing vehicle's acceleration rate = 1.47 mph/sec.
