摘要
为了给智能汽车研发提供有效的场景推演构建方案,统计分析国家车辆事故深度调查体系(NAIS)数据库中乘用车与二轮车发生在十字路口的事故场景数据,得到2类高占比的基础场景;选取7个场景关联变量,并就2类基础场景对应的静态特性数据进行聚类分析;建立运动学推演模型,结合5类典型危险场景的动态参数实际阈值,构建5类典型危险场景的速度-距离危险模型。结果表明:通过统计分类、聚类分析和运动学模型叠加推演方法,可得到5类符合中国道路交通情况的十字路口乘用车与二轮车典型危险场景,进而得出5个危险场景集。
In order to provide an effective scenario deduction and construction scheme for research and development of intelligent vehicles,statistical analysis was conducted on data of accident scenarios between passenger vehicles and two-wheelers at crossroads from National Automobile Accident In-depth Investigation System(NAIS)database,and two types of basic scenarios with high proportion were obtained.Then,seven scenario correlation variables were selected for cluster analysis on static characteristics of these two types of scenarios.Finally,a kinematics deduction model was established,and furthermore,considering actual threshold of dynamic parameters of five types of typical dangerous scenarios,speed-distance danger models of them were constructed.The results show that through methods of statistical classification,cluster analysis and kinematic model superposition deduction,five kinds of typical hazard scenes of passenger cars and two-wheeled vehicles at intersections can be obtained in conformity with traffic situation in China,and moreover five sets of dangerous scenarios are obtained.
