Calculate the length of the transition curve on a plain terrain using the following data:
Design speed = 65 kmph
The radius of the circular curve = 220 m
Allowable rate of introduction of superelevation (pavement rotated about the center line) = 1 in 150
Pavement width including extra widening = 7.5m
