    Calculation of Level Difference in a Two-Lane Road

    Given:
    - Width of two-lane road (W) = 7.5 m
    - Radius of horizontal curve (R) = 510 m
    - Design speed (V) = 100 kmph
    - Acceleration due to gravity (g) = 9.81 m/s²
    - Super-elevation as per IRC: 73-1980

    To find: Level difference between inner and outer edges of the road

    Solution:
    1. Calculation of super-elevation:
    - Super-elevation (e) = V²/(127R + 3.5W)
    - Substituting the given values, e = (100×100)/(127×510 + 3.5×7.5) = 0.0583 or 5.83%

    2. Calculation of level difference:
    - Level difference (h) = e²R/(2g)
    - Substituting the given values, h = (0.0583² × 510)/(2×9.81) = 0.052 m or 52 mm (rounded to three decimal places)

    Answer: The level difference between the inner and outer edges of the road is 0.052 m or 52 mm.
