31. Homework Problem ‐ A freeway ramp has the following characteristics:
Radius on inner edge of pavement equals 100 ft.
One‐lane, one‐way operation with no provisions for passing a stalled vehicle
Design traffic Condition A
Barrier curb on both sides
The ramp pavement width needed (ft) is most nearly:
(A) 15
(B) 16
© 17
(D) 18
SOLUTION:
Reference Table 3‐29, p 3‐103
Answer C
My question is barrier curb are same thing as vertical curb in terms of this problem and so I add 2 ft for the barrier curb?
Please don't make fun of me on this - I know the difference between barrier curb and vertical curb in real engineering world.

The point for this problem is that there are curbs (2). That's all you need to know. So, for Case I, condition A, R = 100', width = 15'. Then for Case I, with 2 curbs, add 2'. I believe the answer should be 17'?
