A server of a driving support system includes a path setting unit configured to set a first traveling path in which a vehicle travels in a parking lot, a detecting unit configured to detect a person, and a determining unit configured to determine whether or not a person is present in a part of the first traveling path, based on the detection result of the detecting unit. When it is determined that a person is present for a predetermined time or more in the part of the first traveling path, the path setting unit searches for a second traveling path that is a path that bypasses the part of the first traveling path, and the detecting unit limits the processing for the measurement result of the sensor whose measurement target is the part of the first traveling path after the second traveling path is searched.
