【摘要】 作为现代城市发展的基础,城市道路交通系统的管理控制一直是城市管理者的一项重要课题。本文研究城市区域交通控制策略,包括区域交通信号控制方法与交通状态分析技术。区域交通信号控制是控制技术与系统综合技术的结合,涉及对整个区域内所有交通信号灯的协调控制；而交通状态分析则是对城市道路交通运行状况的直观体现,也是评价交通控制效果的一个重要指标。本文首先研究了基于主干道协调优先的区域交通信号控制方法。考虑我国城市的实际交通现状,本文在城市区域分层控制思想的基础之上,提出了一种区域路网模型结构,并设计了一种适应我国城市道路交通设施现状的区域交通信号控制新方法。该方法将复杂的面控系统转化为线控系统,降低了区域交通信号优化的复杂度,同时使得整个区域交通能够得到更优的控制效果。本文还研究了基于短时交通预测的交通状态分析技术。出于交通控制对交通信息实时性的需要,本文提出了一种基于短时交通流量预测的路段交通状态分析方法。该方法所建立的交通状态分析模型形式简单,可以有效地提高交通状态分析的效率；同时体现了可能的交通变化趋势,使得交通状态分析能够取得更好的效果。最后,在总结全文的基础上,对城市区域交通控制未来的研究进行了展望。更多还原

【Abstract】 As the basis of the development of the modern cities, urban road traffic management and control system has been an important issue for city managers. This thesis studies regional traffic control policy, including regional traffic signal control method and traffic states analysis technology. Regional traffic signal control method is a combination of control technology and system integration technology, focusing on the coordinated control of all traffic lights in the entire urban region. On the other hand, traffic states analysis is a direct indication of urban road traffic conditions and a kind of performance evaluation of traffic control.Firstly, the method of coordinated regional traffic signal control based on the priority of coordinated main road control is studied in this thesis. Taking the actual traffic situation of our country into consideration, a novel model structure of a regional road network which is based on the idea of hierarchical control of urban areas is proposed in this thesis. Additionally, a regional traffic signal control strategy which is suitable for urban road traffic facilities of Chinese cities is presented. The proposed strategy is able to reduce the complexity of the regional traffic signal optimization via transforming a problem of area traffic control to that of line traffic control and get better performance for regional traffic control.The technology of traffic states analysis based on short-term traffic forecast is also addressed in this thesis. To meet the requirement of real-time traffic information for traffic control, a road section traffic states analysis method based on short-term traffic flow forecast is presented in this thesis. The presented traffic state analysis model in this thesis is simple in style but effective on improving the efficiency.of traffic states analysis. What is more, it is able to indicate the possible trend of traffic evolution and get a better result of traffic states analysis.Finally, the conclusion remarks are presented and the future work on urban regional traffic control is discussed in the end of the thesis.更多还原
