The invention discloses an automatic driving vehicle and pedestrian conflict detection method based on potential collision judgment, relates to the technical field of traffic engineering, and provides a specific detection method for potential collision area calculation by establishing an automatic driving vehicle and pedestrian motion hypothesis. In the traffic conflict judgment, two traffic conflict index acquisition modes are improved by combining the interaction characteristics of the autonomous vehicle and the pedestrian, and the traffic conflict data extraction of the autonomous vehicle and the pedestrian is realized on the basis of a potential collision area acquisition method. Finally, irrelevant data elimination of the traffic conflict data is realized, the data discreteness is reduced, and the accuracy of conflict detection of the automatic driving vehicle and the pedestrian is improved. Moreover, the invention provides an acquisition way of pedestrian safety traffic conflict data, and provides a data source for traffic safety analysis.

    基于潜在碰撞判定的自动驾驶车辆与行人冲突检测方法,涉及交通工程技术领域,本申请通过建立自动驾驶车辆和行人运动假设,提出潜在碰撞区域计算具体检测方法。在交通冲突判定中,通过结合自动驾驶车辆和行人互动特点,改进了两种交通冲突指标获取方式,并以潜在碰撞区域获取方法为基础,实现了自动驾驶车辆和行人交通冲突数据提取。最终实现了对交通冲突数据进行无关数据剔除、并且降低了数据离散性,进而提升了自动驾驶车辆与行人冲突检测的准确率。并且本申请提供了有关行人安全交通冲突数据的获取途径,为交通安全分析提供数据来源。
