    detects a road marking on the basis of the image captured by the camera;

    compares the detected road marking to the stored wear patterns;

    if the detected road marking matches one of the stored wear patterns;

    determines that the detected road marking is the stored type of road marking that is associated with the matching stored wear pattern;

    selects one of the measurement starting points from the plurality of measurement starting points on the basis of the matching stored wear pattern;

    calculates a distance between the vehicle and the detected road marking based on the selected measurement starting point; and
