The invention relates to an urban road intersection traffic control method based on CPS multi-scale, and belongs to the field of traffic informatization. The operation scale of the intelligent automobile information physical system is divided according to the time-space relationship of the urban traffic control system, and the intelligent automobile information physical system is divided into five scales including a node level, a unit level, a subsystem level, a system level and a region level; a signal intersection and vehicle speed combined control method is constructed based on multi-scale characteristics of an information physical system, the breadth and real-time performance requirements of system services of all scales are different, meanwhile, the scales have an inclusion relation, and a plurality of lower-level scales are overall coordinated by higher-level scales; for the proposed multi-scale urban traffic control problem of the information physical system, a basic model of the multi-scale urban traffic control problem is constructed. According to the method, the system boundary can be divided more clearly, the system composition and the operation mechanism thereof can be known, and high-cohesion and low-coupling system decoupling is realized.
本发明涉及一种基于CPS多尺度的城市道路交叉口交通控制方法,属于交通信息化领域。根据城市交通控制系统的时空关系划分智能汽车信息物理系统的运行尺度,将该系统智能汽车信息物理系统划分为节点级、单元级、子系统级、系统级和区域级五个尺度;基于信息物理系统多尺度特征构建了信号交叉口与车辆速度联合控制方法,各尺度系统服务的广度和实时性要求均有所不同,同时,尺度间具有包含关系,多个较低级别尺度由较高级别的尺度统筹协调;对于所提出的信息物理系统多尺度城市交通控制问题,构建了多尺度城市交通控制问题的基础模型。本发明能够更加清晰的划分系统边界,了解系统构成及其运作机制,实现高内聚、低耦合的系统解耦。
