Analysis of Relationship between the steep braking point and the road traffic environment for reducing traffic accidents by foreign driver

Abstract

Recently, with the increase in the number of foreign visitors to Japan, various efforts have been promoted by National Police Agency, Ministry of Land, Infrastructure, Transport and Tourism and private business operators to prevent accidents caused by the rapidly increasing use of foreign car rentals．In addition, urgent safety measures are required, but the cause has not been identified, so it has not been linked to specific measures. In this study, we compared the steep braking point between residents, japanese visitors and foreign visitors (residence: Taiwan, Korea, Hong Kong) to Japan using ETC2.0 probe data on the main island of Okinawa. As a result, the existing method for identifying accident risk points identified sections that were dangerous for foreign drivers visiting Japan, which are likely to be overlooked. The road traffic environment in this section was compared, and the relationship between steep braking by foreign visitors to Japan and the road traffic environment was clarified.
