Minimum Vertical Curve Length Requried for 15 mph road.
(OP)
Does someone know or point me in the right direction on what would be the minimum length needed for a vertical curve where i have an algebraic difference of 5.8%? The road has a 15mph limit for a residential area on a military base in Hawaii (Oahu). The road also T's into a road with a 25mph limit. The algegraic difference does not occur at the intersections but does occur about 30 from the intersection.
Thanks
Thanks

For a 15 mph desighn speed, k=2.0
The length of the vertical curve would 35' for A=.058.
