(A). straights having a total deflection angle 18°36' right by a circular curve of 450 m radius, having cubic spiral transition curves at each end. The design velocity is 70 km/h and the rate of change of radial acceleration along the transition curve is not to exceed 0.4 m/s3. Chainage of I is 2624.20 m. What is the length of the transition curve we need? Refer to Figure 4. Cubic spiral transition curves and circular curve. It is required to join two 0 = 18°36' Circular Transition çurve curve Transition Shift 5イ curve 18°36' – 201 Figure 4 EV (В). Calculate the shift and tangent length using the same preamble in question 5b CR (C). Use actual values. Justify the difference in gradients (p +q) as shown in the following diagram.
