The invention discloses a platform area dynamic blind area risk identification early warning method based on an automatic driving bus, and belongs to the technical field of traffic safety based on automatic driving, and the method comprises the steps: enabling the automatic driving bus to obtain the positions and motion states of other traffic individuals in a sensing range of the automatic driving bus; predicting a future trajectory of each traffic individual so as to obtain a trajectory band of the traffic individual; the traffic individuals with the collision risk are judged according to the track bands of the traffic individuals; blind area division is carried out on traffic individuals with collision risks, and targeted early warning is carried out on traffic individuals which cannot be mutually intervisible; based on environment perception and track prediction functions of an automatic driving bus, synchronous analysis of collision risks among a plurality of traffic individuals and existence of blind areas is carried out, and adverse effects of dynamic vehicle body obstacles are considered, so that judgment of blocking of traffic individual sight lines by dynamic obstacles (namely mobile traffic individuals) is realized; the method is suitable for identification and early warning of risks of complex blind areas of bus stop areas.
本发明公开了基于自动驾驶公交的站台区域动态盲区风险识别预警方法,属于基于自动驾驶的交通安全技术领域,包括自动驾驶公交车辆获取其感知范围内其它交通个体的位置以及运动状态;预测各交通个体的未来轨迹,从而得到其轨迹带;根据各交通个体的轨迹带判断出存在碰撞风险的交通个体;对于存在碰撞风险的交通个体进行盲区分,对相互之间之间不能够相互通视的交通个体进行针对性的预警;基于自动驾驶公交的环境感知与轨迹预测功能,进行多个交通个体之间碰撞风险与是否存在盲区的同步分析,并且考虑动态车体障碍物的不利影响,实现对动态障碍物(即移动交通个体)遮挡交通个体视线的判别,适用于公交站台区域复杂盲区风险的识别与预警。
