摘　　要：To meet the requirements for high-risk testing scenarios in the safety assessment of advanced driver assistance systems(ADASs),this study selected 239 vehicle-to-powered two-wheeler accidents occurring in Xiangtan County from the China In-depth Mobility Safety Study—Traffic Accident(CIMSS-TA)database.Seven scenario elements were selected from the levels of static road elements,dynamic traffic participants and environment elements.The accident characteristics were obtained through statistical analysis.The results showed that 75.73%of accidents occurred at T-junctions/intersections,and 34.73%were caused by visual obstructions.Six typical vehicle-to-powered two-wheeler crash scenarios were established by cluster analysis,including two straight road scenarios(scenarios 3 and 6),two T-junction scenarios(scenarios 1 and 5)and two intersection scenarios(scenarios 2 and 4).Furthermore,six vehicle-to-powered two-wheeler testing scenarios,which represent the traffic environment characteristics of Chinese county-level districts,were constructed by analysing the vehicle/powered two-wheeler speed,the first collision point of the vehicle,the obstacle type and location,etc.The results showed that the vehicle speed in scenario 4 was higher than that in scenario 2,with average values of 34.32 km/h and 21.99 km/h,respectively.The results of this study provide testing scenarios for the safety assessment of ADASs,and contribute to improving vehicle active safety technology.
