摘要
针对城市道路交通拥堵问题,概述了城市交通信号控制系统的组成、功能和特点;考虑交通路网复杂性,交通随机性和动态性等因素,提出了城市交通信号控制系统控制子区划分、自适应控制和交通流信息采集处理3项关键技术;重点描述了关键技术的模型和处理方法。最后通过实际案例验证了控制子区划分技术。
Aimed at the city traffic congestion problem, the structure, functions and features of the urban traffic signal control system are introduced. Considering the complexity, randomness, dynamics of the road network, three key technologies for the control sub-area division, adaptive control and the traffic flow collection and processing are proposed. Then, models and processing methods for three key technologies are mainly discussed. Finally, the technology of control sub- area division is verified by practical cases.
