摘要
为研究复杂的城市常规路路段的交通流相,根据某城市路段车辆的流动量,对该城市常规道路各种交通流相的变化进行了二流分析,研究了交通密度与排列长度的变化关系。依据数据调查结果和数学推导方法,将城市常规道路路段的交通流相划分成畅通相、强迫相及拥堵相。其结果可为城市道路路段中常规路的交通流系统运行状态模拟、判断提供理论依据。
The traffic flow of complex city routine roads is studied. According to the flow of an urban road vehicles, the changes of the city routine road traffic flow phase are analysed, and the relationship between the traffic density and the queue length is studied. The city routine road traffic flow is divided into smooth phase, forcing and congestion phase by using the data survey results and the mathematical deduction method.The results can provide the theoretical basis for the traffic flow system running state of simulationa and judge in the urban conventional road section.
