The invention discloses a vehicle path forecasting method based on a generalized possibility Kripke structure model. The method comprises the steps of constructing an actual road condition model, constructing a path transfer distribution matrix, quantifying an initial traffic condition, constructing a vehicle path forecasting atomic proposition, quantifying a label value, carrying out model detection, evaluating the advantages and disadvantages of a road intersection, and forecasting an optimal path. Compared with a possibility Kripke structure, the road traffic condition is modeled by adopting a generalized possibility Kripke model, the road intersection is used as a state space, the unblocked degree of a road section is used as a path transfer distribution matrix, and the average vehicle passing speed, the average red light waiting time and the traffic violation index are used as label values; the optimal path forecasting method for modeling according to the generalized possibility Kripke structure is provided, the technical problem of calculation difficulty is solved, and the method has the advantages of being easy in data acquisition, simple and convenient in execution process and the like, and has certain value for implementation measures of traffic management and forecasting.

    一种基于广义可能性Kripke结构模型的车辆路径预报方法,由构建实际路况模型、构建路径转移分布矩阵、量化初始交通状况、构建车辆路径预报原子命题、量化标签值、进行模型检测、评估道路交叉口的优劣、预报最优路径组成。本发明与可能性Kripke结构相比,采用广义可能性Kripke模型对道路交通状况进行建模,将道路交叉口作为状态空间,路段的畅通程度作为路径转移分布矩阵,车辆平均通过速度、红灯平均等待时间和交通违章指数作为标签值,提出了根据广义可能性Kripke结构建模的最优路径预报方法,解决了计算困难的技术问题,具有数据易获取、执行过程简单方便等优点,对交通管理与预报的实行措施具有一定价值。
