However, a central road safety organisation with adequate human, technical and financial resources is essential (Bliss and Breen, 2009). As a result, traffic safety emerged as a highly important social issue. In June 1970, the Government of Japan, responded by enacting the Traffic Safety Policies Act (Act No.l 10 of 1970), with the aim of promoting traffic safety measures nationwide in a total and systematic manner. Under this act, the government has been working together with local governments and relevant private organisations to vigorously implement traffic safety measures.
