The invention discloses an intersection collision risk quantification method in an intelligent network connection environment. According to the technical schemes of the invention, in the intelligent network connection environment, vehicle motion state information and an actual traffic flow state in an intersection are sensed and obtained,and vehicle motion trajectories are predicted; and an intersection risk function is established based on the minimum time interval when a vehicle passes through each position in an intersection plane, wherein the intersection risk function is used for intersection collision risk quantification. According to the intersection risk quantification method provided by the invention, the intersection collision risk can be dynamically quantified according to the actual traffic flow state, driving suggestions are provided for network-connected manual driving vehicles, corresponding operations are adopted in advance to ensure that the vehicles safely pass through the intersection, guidance suggestions are provided for the safety control strategies of network-connected automatic driving vehicles, and a theoretical basis can be provided for intersection channelization and signal timing optimization.

    本发明公开了一种智能网联环境下交叉口碰撞风险量化方法,技术方案是在智能网联环境下,感知获取交叉口内车辆运动状态信息和实际的交通流状态,并且对车辆的运行轨迹进行预测,基于车辆通过交叉口平面内各个位置的最小时间间隔建立交叉口风险函数,用于交叉口碰撞风险量化。本发明所提出的交叉口风险量化方法能够根据实际的交通流状态动态量化交叉口碰撞风险,为网联人工驾驶车辆提供驾驶建议提前采取相应的操作保证车辆安全通过交叉口,为网联自动驾驶车辆安全控制策略提供指导意见,并且能够为交叉口渠化与信号配时优化提供理论依据。
