Development of paved road " Melody Road " which plays music.

By grooving construction of road surface, the road where music was audible, when car runs, was constructed experimentally. The grooving is an installation method which cuts multiple thin grooves on road surface. The vibration sound by contact of tire and grooves is generated, when car passes the road surface that the grooving was conducted. The grooving is carried out by adjusting groove interval, and high vibration sound is generated in the place where the groove interval is narrow, and low vibration sound is generated in wide place. On the basis of musical score which corresponded to one node of the Shiretoko ryojou, the grooving grooves were designed, and the construction test was carried out. Estimation speed of the rolling stock is made to be 60km/h, and the construction distance is 250m. The melody arose during about 15 seconds clearly, when car run this road surface at 60km/h. link
