Samenvatting
Road accident reduction in the 1970's in Japan was drastic. The fatalities were halved while total distance of travel increased 1.7 times from 1970 to 1979. The trend in the 1980's, however, indicates a gradual but obvious increase despite the continuous efforts at accident prevention. Shown are the reasons for the past success and failure in accident prevention. These reflections of our experiences in the past will automatically lead to the measures that should be taken from now on.
