中文摘要: 本研究以Daganzo提出的宏观基本图(Macroscopic Fundamental Diagram, MFD)理论为依据,建立我国城市交通流的宏观基本图,并基于此模型提出交通网络的运行评价方法。本研究的核心是采用仿真和大量实测数据相结合的方法,通过对比分析不同国家、国内不同城市的交通流宏观基本图(MFD),得出我国城市交通流MFD存在的前提和其影响因素的定量分析;为了实现分层次的交通网络区域评价,拟制定按地理位置和按道路等级的两种不同的划分原则,对交通网络进行区域划分;同时提出基于MFD理论的网络交通评价方法,重点在于提出不同区域和不同道路等级的评价指标和阈值;最后通过实测数据验证研究框架和方法以及结果的合理性与稳定性。研究结果为网络层面的协同交通控制管理方法提供理论参考价值,为最优化利用交通网络资源提供依据。

英文摘要: The realization of traffic evaluation,control and management in macroscopic network level in cities relies heavily on network traffic model. This research will build urban traffic Macroscopic Fundamental Diagram(MFD) in Chinese cities which is firstly put forward by Carlos F. Daganzo, and establish traffic network evaluation method based on this theory.The role of this research is to investigate the prerequisite of existence of MFD in Chinese urban traffic, and to analyse quantificationally the impact factors of MFD by comparing the MFD in different countries and in different cities in China, combining simulation method and aboundant real data on site. Secondly, in order to realize network evaluation and network traffic control in different size of traffic areas, zones division principle and method on traffic network is put forward accroding to geographical position and road grade, based on the theory of MFD in Chinese cities. Thirdly, network traffic evaluation method is accordingly estabilished base on MFD, focusing on the defination of evaluation indicators and threshold values. At the end, the rationality and stability of research framework, method and result will be examined using real data on site. The research result is helpful for integrated traffic control and management in network level and also is the
