This system includes a body frame mounted on the road surface, a movable frame movably supported by this body frame, and a laser ray transmitting-receiving section connected to this movable frame. The laser ray transmitting-receiving section is additionally provided thereon with a signal process circuit, by which received signals are processed in a predetermined manner, whereby the irregularities of the road surface are measured. Processing performed in the signal process circuit is controlled in timing in accordance with a moving speed of the laser ray transmitting-receiving section.
