The　facilities　for　slowing　down　the　vehicle　speed　are　settled　in　the　highway　through　town,　such　as　speed　hump.　A　wave-shape　pavement　which　has　characteristic　of　riding　comfort　and　vehicle　smoothly　is　suggested　to　slow　down　the　vehicle　speed.　Four　kinds　of　the　wave-shape　pavement　are　designed　and　simulated.　Driving　test　is　performed　by　using　driving　simulation　vehicle　in　the　room　under　different　driving　speed.　The　mean　square　of　weighed　acceleration　is　recorded　and　the　relation　model　between　the　driving　speed,　mean　square　of　weighed　acceleration　and　wavelength　of　wave-shape　pavement　is　obtained.　Then　the　design　method　and　indicators　are　proposed　accordingly.　Test　result　shows　that　the　wave-shape　pavement　can　make　driver　slow　down　the　driving　speed　voluntarily.　Therefore,　the　speed　limit　can　be　achieved　by　constructing　suitable　wave-shape　pavement.　©　right.
