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 superelevation is 7%. The provided horizontal curve radius is 700m. Would the designed curve radius will be sufficient to attain the superelevation? If not, what would be the correct radius for horizontal curve? When suggesting a new radius please check and make sure that the provide superelevation is higher (>7%) than required
