A highway reconstruction project is being undertaken to reduce accident rates. The reconstruction involves a major realignment of the highway such that a 100 km/h design period is attained. At one point on the highway, a 245 m equal tangent crest vertical curve exists. Measurements show that at 0 107.290 station from the PVC (or VPC), the vertical curve offset is 1m. Assess the adequacy of this existing curve in light of the construction design speed of 100 km/h and, if the existing curve is inadequate, compute a satisfactory curve length (Consider both minimum and desirable SSDs)
