A highway reconstruction project is being undertaken to reduce accident rates. The
construction involves a major re-alignment of the highway such that a 120-km/h design speed
is attained. At one point on the highway, a 245-m crest vertical curve exists. Measurements
show that at 0+107.290 from the BVC, the vertical curve offset is 1 meter. Assess the
adequacy for SSD requirements of this existing curve in light of the reconstruction design
speed of 120 km/h. If the existing curve is inadequate, compute a satisfactory curve length.
