Abstract
Active discussion is being conducted for the harmonization of international safety assessment for automated driving, however, it is predicted that traffic characteristics are different in each country. Thus, it is necessary to clarify which standards, or parts of standards, should be the same all over the world and which need to be considered for each country. In this article, we focus on those for each country. We analyzed and compared German and Japanese cut-in scenarios using traffic data which measurement vehicles collected on German and Japanese expressways to grasp country-specific traffic characteristics. Results revealed that the relative velocity and distance between the measurement vehicles and cut-in vehicles in each country are different. Therefore, in order to harmonize international standards of safety assessment for automated driving, the importance of considering country-specific traffic characteristics is shown.
