Abstract
In a control apparatus, an acquisition unit acquires the coordinates of a detection starting position and detection ending position detected by a radar, for each of a plurality of moving vehicles moving along a road. A calculation unit calculates an average value of the coordinates of the detection starting positions and an average value of the coordinates of the detection ending positions, and stores information of radar detection including the calculated average values in a radar detection storage unit. A comparison unit compares the average values of the coordinates of the detection starting positions and detection ending positions with respective determined reference values. An abnormality determination unit determines based on the comparison results whether or not an abnormality has occurred in the radar, and outputs, if determining that an abnormality has occurred, information indicative of the occurrence of the abnormality.
