【摘要】 “基于数据”是指研究的出发点是被研究系统的实际运行数据,通过对数据的分析来获得被研究对象的特征、模式和规律,进而实现对系统的管理和控制。“网格化”,又可称为是单元化,是一种系统划分和组织形式,目的是通过将系统“网格化”来降低系统的复杂性,从而实现管理水平的提升、控制效果的改善等。论文以城市交通系统为研究对象,基于数据驱动思想和网格化管理理论探讨城市数字交通系统的构建和实现。建立了基于数据的网格化城市交通信息系统体系框架,提出交通网格的划分原则以及网格化交通流数据采集设备布点原则,并在此基础上,进行了交通系统运行状态的评价等相关研究。在城市交通系统研究中,无论是基于数据的理论还是网格化管理理论的研究和应用都属于前沿课题。论文的主要研究内容和创新点总结如下：(1)给出数字交通的一种定义,研究了城市交通系统的发展规律。从已提出的数字交通的概念和内涵分析出发,提出数字交通新的定义；指出城市交通系统发展的3个阶段,分析了交通工程、数字交通与智能交通发展阶段的特点以及相互之间的关系。(2)给出了基于数据的网格化城市交通信息系统的研究框架,提出基于数据的网格化城市交通管理系统的运行机制、触发机制等。(3)提出了一种交通网格概念,给出交通网格的划分原则和方法,归纳了网格化交通流数据采集技术选择,给出了网格化数据采集设备布点原则。(4)以交通流的实际数据为基础,针对信号化交叉口,提出一种基于数据的单交叉口交通信号控制系统运行状态评价方法；针对快速路交通,提出一种基于路段旅行时间的快速路拥堵状态评价方法；针对交通网格,提出了基于核查线的交通网格运行状态评价方法。(5)通过项目“深圳市网格化车牌照识别信息综合应用系统”,实现了论文中的部分内容,并对系统建设的不足也进行了总结。更多还原

【Abstract】 "Based on the data" refers to the starting point of research is the system practical operation data. By analyzing the data, we can obtain the characteristics, patterns and rules of the object, and then realize the management and control to the system."Gridding", also known as unitization, is a type of system division and organization method. The aim of it is to reduce the complexity of system in order to upgrade the management level and improve the control effect.The research object of this paper is the urban traffic systems, and the construction and implementation of the urban traffic system are discussed based on data-driven ideas and grid management theory. In this paper, the data-based gridding urban traffic information system framework is established. The principles of how to divide the traffic grid and deploy the collection equipments for flow data in gridding traffic are proposed, and further, how to evaluate the running status of the transportation system and so on is studied. In urban traffic system studies, the research and application of whether the theory based on data or the theory of gridding management are all cutting-edge issues. The main researches and innovations are summarized as follows:(1) The new concept of "Digital Traffic" is proposed, and doing a reaserch about the developing disciplines of urban transportation systems.By analyzing the current concept and connotation of "Digital Traffic", proposing the new definition of "Digital Traffic". Point out the3stages of the developing of urban transportation system. Analyze the features of the developing of traffic engineering, and digital traffic and intelligent traffic and the relations between them.(2) Proposing the research framework of the data-based gridding urban traffic system, and the running mechanism and trigger mechanism of data-based gridding urban traffic management system.(3) Proposing a notion of traffic grid. The principle of division of traffic grid and gridding traffic flow collection technologies selection is studied. On this basis, the gridding traffic flow detector distribution principle is proposed.(4) A data-based single intersection signal control performance measurement method based on dynamic data is proposed. A freeway congestion identification method based on section travel time is proposed. A traffic grid performance measurement method based on check line is proposed. (5) In the project of "The gridding vehicle license plate recognition information integrated application system of Shenzhen", a part of the theory in this paper has been implemented, and the shortages in system construction have been summarized.更多还原
