CURVE on the basis of super ELEVATION is given by:Case 1: Rotation of pavement by inner EDGE:L = N × ECase 2: Rotation of pavement about centres:L = \(\frac{{N \times E}}{2}\)Where, N = Rate of Super elevation,E = Superlevation and it is given asE = eWWheree is rate of super elevation and W is width of roadCalculationGiven: e = 1/15; W = 10 m and N = 120Considering Case 1:\(L = 120 \times \frac{1}{{15}} \times 10\)⇒ L = 80 mConsidering Case 2:\(L = 120 \times \frac{1}{{15}} \times \frac{{10}}{2}\)⇒ L = 40 mSince, L = 40 m is not in option, we go for case 1 and LENGTH of transition curve is 80 m.
