Design a vertical curve on the two-lane bidirectional bidirectional road connecting the two alignments. Calculate the red elevation at “12+426” on the road route. L min=100m. tr=1 second (driver reaction time), f=0.3 [Given: Vp= 85 km/h, S1km= 12+500 km, SI elevation=235 m, g1=3.9%, g2=-3.4%] NOTE: The slope value will be taken as the ramp down slope to stay on the safe side. NOTE: Do not round any value. Use it as is.
