本发明涉及一种联合车辆优先级和人工鱼群的多车协同决策系统,属于交通信息化领域。系统发明分为三部分:车间力场分析子系统、车车协同关系分析子系统和多车协同规划决策制定子系统。针对传统力场处理动态环境存在建模效果差的问题,设计一种考虑车速的势场模型,考虑基于距离关系的车间作用力和车速变化过程中的相互作用力,提高在动态环境下车群之间相互作用力的建模准确度。在单车处理中设计优先级算法,针对多车情况设计三种协同方案。本发明充分利用路端智能路侧感知与V2X通信技术获取交通实时数据,将数据处理主要集中在路侧高性能计算设备中,并对路侧多车协同决策模型进行优化,可有效提高路口通行效率、减少路口拥堵。

    The invention relates to a multi-vehicle collaborative decision-making system combining vehicle priorities and artificial fish schools, and belongs to the field of traffic informatization. The system is divided into three parts: a workshop force field analysis subsystem, a vehicle-vehicle cooperative relationship analysis subsystem and a multi-vehicle cooperative planning decision making subsystem. Aiming at the problem of poor modeling effect of a traditional force field processing dynamic environment, a potential field model considering the vehicle speed is designed, and the modeling accuracy of the interaction force between vehicle groups in the dynamic environment is improved by considering the workshop acting force based on the distance relation and the interaction force in the vehicle speed changing process. A priority algorithm is designed in single-vehicle processing, and three cooperation schemes are designed for a multi-vehicle condition. According to the invention, the traffic real-time data is obtained by fully utilizing the intelligent roadside sensing and V2X communication technology of the roadside, the data processing is mainly concentrated in the roadside high-performance computing equipment, and the roadside multi-vehicle collaborative decision-making model is optimized, so that the traffic efficiency of the intersection can be effectively improved, and the congestion of the intersection can be reduced.
