A STUDY FOR GENERATION FACTOR OF ROAD TRAFFIC NOISE IN OKINAWA

Okinawa is the southernmost prefecture of Japan. It is located in the East China Sea about 1,700 km south of Tokyo. Okinawa consists of many small islands which form the Ryukyu archipelago just off the great Asian land mass. The main island of Okinawa is the largest of all. Ishigaki Is. and Miyako Is. are among the second group in size. These islands have no railroad, so they solely rely on the means of vehicular transportation. This is why we selected Okinawa for our study site to investigate the factors that contribute to the generation of road traffic noise. At first the measured data of traffic noise that had been collected by road authorities for almost two decades was surveyed. Then, extensive research was carried out among a variety of researched items: the noise level of second hand cars, especially of older models, seemed to have been of interest. Used ears are popular and account for a larger percentage of the total cars owned on Okinawa Prefecture. For the covering abstract see IRRD E104312.
