摘要
基于交通数据驱动的基础场景构建与基于机理与理论的逻辑场景构建两种方法相结合,即通过关联规则算法对交通事故数据进行挖掘,得到由若干交通事故特征变量组成的基础场景,再对基础场景中主车周围的交通参与者及其运动方向进行排列组合,从而泛化出更多的逻辑场景,形成场景库。
This paper combines traffic data-driven basic scene construction with mechanism and theory-based logical scene construction,namely mining traffic accident data through association rule algorithm to obtain the basic scene composed of several traffic accident characteristic variables.Then arrange and combine the traffic participants and their movement directions around the main vehicle in the basic scene,so as to generalize more logical scenes and form scene library.
