The field geometric data did not present significant variations in lane width, shoulder width and superelevation. |
The horizontal curve properties include radius of curve, deflection angle, and superelevation. |
The right-hand curve was 209 feet long with no superelevation. |
The desired speed and curve radius determine the amount of superelevation. |
This tendency is counteracted by designing the cross section with superelevation. |
Tip: the relative altimeter can be used for example for measuring the superelevation above landing site. |
