摘　　要：为规避或缓解红绿灯路口前车停车让行时遭到失控后车追尾的严重事故,基于前序研究建立的行车风险场力的基本模型,提出了行车风险的矢量场建模方法。设计了无信号灯交叉路口场景,并进行6组不同状态下的行车安全场仿真计算;设计了红绿灯路口前车停车让行时即将遭到失控后车追尾的危险场景,分析了直行、左转、右转和掉头等4种不考虑道路交通规则约束的避险路径,对比分析了12组不同状态下的行车风险场力分布。结果表明:所提模型可以有效辨识行车风险,自车掉头进入另一侧车道的避险方案最佳,且当车速为3 m/s时能将整体风险降低67.41%。To mitigate or alleviate the occurrence of serious accidents where a preceding vehicle stops to yield at a traffic light intersection and was rear-ended by an out-of-control vehicle,a vector field modeling method for vehicle risk was proposed based on the fundamental model of driving risk field force established in the previous studies.An intersection scenario without traffic signals was designed and the safety simulations was conducted under six driving conditions.A dangerous scenario was developed,where a vehicle at a traffic light intersection was at risk of being rear-ended by an out-of-control following vehicle;then,four evasive maneuvers(going straight,turning left,turning right,and making a U-turn)was analyzed without considering road traffic regulations;finally,the force distribution of driving risks across twelve conditions were compared and analyzed.The results show that the proposed model can effectively identify driving risks.The evasive maneuver of the vehicle making a U-turn into the opposite lane is the most optimal,reducing overall risk by 67.41%when the speed is 3 m/s.
