There is a need for conducting a design check for a horizontal curve (flat terrain) for an intermediate speed highway in rural Victoria. Given the design speed is 80kmph and super elevation is 7%. The provided horizontal curve radius was equal to the 700 m. Would the designed curve radius will be sufficient to attain the super elevation? If not, what would be the correct radius for horizontal curve? When suggesting a new radius please check and make sure that the provide super elevation is higher (>7%) than required.

Intersection Design

An intersection is a location where two or more roads or railways meet or join. The traffic movement is controlled at the intersection that depends on its design and type. It governs the operation, efficiency, speed, capacity, and safety of the highways, airways, and railways. The movement of the pedestrian causes hazards and delays at the intersection.
