Question 63
CE2NAT2 marksNeeds review
A vertical summit curve on a freight corridor is formed at the intersection of two gradients, +3.0% and −5.0%.
Assume the following:
Only large-sized trucks are allowed on this corridor
Design speed = 80 kmph
Eye height of truck drivers above the road surface = 2.30 m
Height of object above the road surface for which trucks need to stop = 0.35 m
Total reaction time of the truck drivers = 2.0 s
Coefficient of longitudinal friction of the road = 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 2 decimal places).
