A two-lane SH of width 7m was constructed through a plain terrain. The radius of the circular curve was equal to the minimum ruling radius. The maximum values of superelevation and coefficient of lateral friction were used for calculating the length of the transition curve. For the vehicles negotiating the curve the distance between the front and back wheel was found to be 6.1 m. The road is rotated through the centerline. The design speed of vehicles was found to be 100 km/hr. Extra widening if required was done as per IRC standards. Take C = 0.5 m/s3. The length of the transition curve is ______m based on centrifugal acceleration.
