摘　　要：以广域浮动车数据为基础,将路网作为一个整体的研究对象,建立了宏观路网运行状态的等级评价模型。定义了适合宏观评价的交通网格模型,提出了宏观路网运行状态评价指标体系;通过广域浮动车数据处理和分析,提出了宏观评价指标的计算模型,并在此基础上,建造了宏观路网运行状态的评价模型;最后,以北京市为例,对固定分区的区域路网进行了宏观路网运行状态的评价,结果表明该评价方法稳定可行。Based on the floating car data,taken the whole road network as an object of study,the macroscopic road network traffic running status level evaluating model was established.The traffic grid model that is fit for the macroscopic evaluation was defined,and the evaluating indicator system of macroscopic road network running status was proposed.On the basis of wide area floating car data processing and analysis,the macroscopic indicator computation model was proposed,then the macroscopic road network running status evaluating model was constructed.Finally,taken Beijing as a case study example,the macroscopic traffic road network running status evaluation of urban road network in the fixed divided regions was conducted,and the result shows that this assessment method is feasible.
