A method for determining a risk boundary in response to a plurality of indications of an emergency braking event, where the risk boundary indicates a plurality of speed flow pairs at which a risk of the emergency braking event is below a threshold; determining a set of speed flow pairs of average speed and vehicle count and a plurality of indications of emergency braking events at the road segment level; determining a host vehicle speed; and performing at least one of decreasing the host vehicle speed and increasing the host vehicle following distance in response to the host vehicle speed exceeding the risk boundary for the vehicle flow density.

    一种方法,用于:响应于紧急制动事件的多个指示来确定风险边界,其中风险边界指示多个速度流量对,在该风险边界处,紧急制动事件的风险低于阈值;在路段级别确定平均速度和车辆计数的一组速度流量对以及紧急制动事件的多个指示;确定主车辆速度;以及响应于主车辆速度超过针对车辆流量密度的风险边界来执行降低主车辆速度和增加主车辆跟随距离中的至少一种。
