The invention discloses a method for resolving a conflict area of an urban intersection. The method comprises the following steps: step S1, a user customizes an intersection traffic rule; s2, the vehicle identifies a conflict circle and enters the conflict circle; s3, judging whether other vehicles exist in the conflict circle or not; s4, extracting motion parameters of vehicles of two conflicting parties; s5, judging the position information of the conflicting vehicles; S6, calculating the time when the vehicles of the two conflicting parties arrive at the conflicting point; and S7, judging the final priority of the vehicles according to whether the vehicles are in the plurality of conflict circles at the same time. The method provided by the invention is suitable for most of intersections and is not limited by the shapes of the intersections; the problems of confluence and intersection conflicts of mixed traffic flows of different lanes can be solved at the same time; according to the method, confluence and cross conflict areas are identified, and the priority of the passing right is determined; and compared with the prior art, the difficulty of constructing the model is smaller in calculated amount.
本发明公开了城市交叉口冲突区域的消解方法,包括以下步骤:步骤S1,用户自定义交叉口通行规则;步骤S2,车辆识别冲突圆并进入冲突圆;步骤S3,判断冲突圆内是否有其他车辆;步骤S4,提取冲突双方车辆运动参数;步骤S5,判断冲突车辆的位置信息,步骤S6,计算冲突双方车辆到达冲突点的时间;步骤S7,根据车辆是否同时处于多个冲突圆内,判断车辆最后的优先次序。本发明中的方法适用于绝大多数交叉口,不受交叉口形状限制;能同时解决不同车道的混合交通流合流、交叉冲突的问题;在本发明中,对合流、交叉冲突区域的识别以及对通行权的优先级;所构建模型的难度相较于现有技术其计算量较小。
