1. A crest vertical curve connects a +1.5 % grade with a -2.5 % grade on a two-lane highway. The
criterion selected for design is the minimum stopping sight distance for a design speed of 90 km/h
based on AASHTO (2004) design criteria. If the grades intersect at station (14+465) at an elevation of
100 m, compute the station and elevation of BVC, EVC, and highest point. Also, compute the
elevation of the curve at 50-m intervals. Display all results in a tabular form.
