Design rate of super elevation for horizontal highway curve of radius 450 m for a mixed traffic condition, having a speed of 125 km/hour is
-
- 1.0
- 0.05
- 0.07
- 0.154
- 1.0
Correct Option: D
For mixed traffic,
e = | ; V in m / s | |
gR |
Design speed = 125 kmph
= 125 × | = 34.7 m /s | |
18 |
e = | ||
gR |
= | = 0.154 | |
