1. A method of determining a height correction function associating each of a plurality of vehicle positions to a respective height correction value, the plurality of vehicle positions being within a predetermined region defined relative to a roadside unit, the method comprising:
determining, for each of the plurality of vehicle positions, a direct distance, the determined direct distance between the vehicle position and a position of the roadside unit;
determining, for each of the plurality of vehicle positions, a planar distance, the determined planar distance between the vehicle position in a horizontal plane containing the vehicle position and a projection of the position of the roadside unit onto the horizontal plane;
calculating, for each of the plurality of vehicle positions, a height of the roadside unit relative to the vehicle position using the direct distance and the planar distance determined for the vehicle position;
setting, for each of the plurality of vehicle positions, a value indicative of the height of the roadside unit relative to the vehicle position as a height correction value; and
storing in the roadside unit, for each of the plurality of vehicle positions, the height correction value of the vehicle position in association with information indicative of the vehicle position as the height correction function.
