At what distance from the centerline of the inside of a 2-lane highway horizontal curve can a house can be placed without impacting the required stopping distance of 74.1 meters (m) if the radius of the curve is 200 meters and the speed limit is 50 kilometers/hour (km/h)?

Question

Quizplus · Accepted Answer

A house can be placed 3.43 m from the centerline of the inside of a 2-lane highway horizontal curve without impacting the required stopping distance of 74.1 m.
Solution: Use the horizontal curve equation for when S< L (metric units)
m = R (1-cos (28.65S/R)
Where, S = 74.1 m
R = 200 m
m = 200(1-cos [(28.65) (74.1)/200])
= 3.43 m
