passing equation - help please I am really confused :yuck: with this stuff, old timer needs some help.... 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? 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 Initial speed of passing vehicle = 50 mph Passing speed of passing vehicle = 60 mph Speed of slow vehicle = 50 mph Speed of opposing vehicle = 60 mph Length of passing vehicle = 22 ft Length of slow vehicle = 22 ft Clearance distance between passing and slow vehicles at lane change = 20 ft Clearance distance between passing and slow vehicles at lane re-entry = 20 ft You should also assume that the passing vehicle accelerates to passing speed before moving into the left lane. The distance travelled by slow vehicle ?? The distance traveled by passing vehicle ?? The distance travelled by opposing vehicle ?? The time taken for passing vehicle to complete the pass ?? The relative distance ?? The clearance distance between opposing vehicle and passing vehicle upon lane re entry ??
