👉Road Superelevation & Formula
🚧Superelevation is the upward slope (banking) of the outer edge of a road on a horizontal curve.
🪧It helps counter centrifugal force, improving vehicle stability and safety.
❇️Formula:
e + f = V^2/127R
🔗Where:
e = Superelevation (decimal)
f = Side friction factor
V = Design speed (km/h)
R = Radius of curve (m)
📎Why it matters:
Reduces skidding risk
Prevents vehicle overturning
Improves passenger comfort
Allows safer travel at higher speeds on curves
