Question

A vertical summit curve on a freight corridor is formed at the intersection of two gradients, +3.0%+3.0\% and 5.0%–5.0\%.
Assume the following:
Only large-sized trucks are allowed on this corridor
Design speed =80 kmph= 80 \text{ kmph}
Eye height of truck drivers above the road surface =2.30 m= 2.30 \text{ m}
Height of object above the road surface for which trucks need to stop =0.35 m= 0.35 \text{ m}
Total reaction time of the truck drivers =2.0 s= 2.0 \text{ s}
Coefficient of longitudinal friction of the road =0.36= 0.36
Stopping sight distance gets compensated on the gradient
The design length of the summit curve (in meters) to accommodate the stopping sight distance is __________ (rounded off to 22 decimal places).
