The design speed of a multilane highway is 60 mi/h. Determine (a) the minimum stopping sight distance that should be provided for a level roadway, and (b) the minimum stopping sight distance that should be provided for a roadway with a maximum grade of 7 percent. Note: the term a/g in the appropriate equation is typically rounded to 0.35 for calculation purposes. Assume perception reaction time = 2.5 sec.
The minimum sight distance required in these cases is the stopping sight distance (SSD), given by Equation 3.27:
where u = design speed (mi/h)
t = perception-reaction time (sec)
a = rate of deceleration (taken as 11.2 ft/sec2)
g = gravitational acceleration (taken as 32.2 ft/sec2)
G = grade
