The invention discloses an intersection vehicle conflict early warning method in an intelligent network connection environment, computer equipment and a storage medium. The method specifically comprises the following steps: acquiring micro data of an intelligent network connection vehicle and a target intersection; performing grid network modeling on the intersection space, and establishing a grid space occupation matrix; predicting a vehicle track according to the vehicle driving data and calculating a vehicle track transverse static buffer area and a longitudinal dynamic buffer area of the vehicle in each time step length; and combining the transverse static buffer area and the longitudinal dynamic buffer area of the track to obtain a comprehensive safety buffer area, and judging a conflict relationship between the comprehensive safety buffer area and an expected grid network occupancy state so as to accurately identify and warn potential track conflicts before the vehicle enters the intersection.

    本发明公开了一种智能网联环境下交叉口车辆冲突预警方法、计算机设备、储存介质,具体包括:获取智能网联汽车及目标交叉口微观数据;对交叉口空间进行栅格网络建模,并建立栅格空间占用矩阵;根据车辆行驶数据预测车辆轨迹并计算车辆在每个时间步长内的车辆轨迹横向静态缓冲区和纵向动态缓冲区;将轨迹横向静态缓冲区和纵向动态缓冲区合并得到综合安全缓冲区,判断综合安全缓冲区与预期栅格网络占用状态的冲突关系,以便在车辆进入交叉口前精确识别并预警潜在的轨迹冲突。
