本发明实施例公开一种实时车辆换道风险评估方法、计算机设备及计算机存储介质,包括:获取车辆的轨迹数据,得到换道车辆的车辆信息;确定目标车道,根据所述车辆信息识别车辆换道的起始时刻和结束时刻,得到换道时长;其中,所述起始时刻为所述换道车辆的车头进入所述目标车道的时刻,所述终止时刻为所述换道车辆车尾进入所述目标车道的时刻;根据所述车辆的轨迹数据,确定与所述换道车辆满足预设碰撞时间的待碰撞车辆;基于所述待碰撞车辆和所述换道车辆的车辆信息,通过时空重叠分析满足在相应位置满足预设条件,对所述换道车辆进行风险评估;如此,能够评判出更为准确地评估换道风险;能够用于判断车辆是否在时间和空间上均存在冲突。
The embodiment of the invention discloses a real-time vehicle lane changing risk assessment method, computer equipment and a computer storage medium, and the method comprises the steps: obtaining the trajectory data of a vehicle, and obtaining the vehicle information of a lane changing vehicle; determining a target lane, and identifying a starting moment and an ending moment of vehicle lane changing according to the vehicle information to obtain a lane changing duration; wherein the starting moment is the moment when the head of the lane changing vehicle enters the target lane, and the ending moment is the moment when the tail of the lane changing vehicle enters the target lane; according to the trajectory data of the vehicle, determining a to-be-collided vehicle meeting preset collision time with the lane changing vehicle; based on the vehicle information of the to-be-collided vehicle and the vehicle information of the lane changing vehicle, performing risk assessment on the lane changing vehicle by meeting a preset condition at a corresponding position through space-time overlap analysis; therefore, the lane changing risk can be evaluated more accurately; the method can be used for judging whether the vehicles have conflicts in time and space or not.
