A horizontal curve on a two-lane highway is designed with a 610-m radius, 3.5-m lanes, and 80 kph design speed. Determine the distance that must be cleared from the inside edge of the inner lane to provide sufficient stopping sight distance. (Note: Curve radius is typically reckoned from the centerline of the roadway, and driver location is assumed to be at the middle of the travelled lane.) Assume coefficient of friction as 0.35.

Can you show me the detailed solution for this problem? the answer is already given in the photo.

A horizontal curve on a two-lane highway is designed with a 610-m radius, 3.5-m lanes, and 80 kph
design speed. Determine the distance that must be cleared from the inside edge of the inner lane to
provide sufficient stopping sight distance. (Note: Curve radius is typically reckoned from the centerline
of the roadway, and driver location is assumed to be at the middle of the travelled lane.) Assume
coefficient of friction as 0.35.
Answer:
M = 4.0 m
