The invention discloses a traffic operation state discrimination method and system, and belongs to the technical field of intelligent high-speed traffic situation analysis, and the method comprises the steps: calculating a channel interruption rate, a channel congestion degree, a road interruption rate and a road congestion degree, and carrying out the standardization processing of the four single indexes, and obtaining the standardization value of each single index; and then calculating a traffic operation index based on the single index and the standardized value thereof, and determining a traffic operation state according to a preset traffic operation index grade. According to the method, the overall operation condition of the channel traffic flow is described based on the traffic operation index, the traffic efficiency of the road traffic flow is measured, the judgment of the traffic operation state is realized, and quantifiable data support and basis are provided for intelligent traffic management and control.
本发明公开了一种交通运行状态判别方法及系统,属于智慧高速交通态势分析技术领域,通过计算通道中断率、通道拥挤度、道路中断率、道路拥挤度并对上述4个单项指标进行标准化处理,得到各单项指标的标准化值;然后基于单项指标及其标准化值计算交通运行指数,根据预设的交通运行指数等级确定交通运行状态。本发明基于交通运行指数描述通道交通流的整体运行情况,衡量道路交通流的通行效率,实现交通运行状态的判别,为交通智能管控提供可量化的数据支撑和依据。
