We analyze traffic data from a highway section containing one effective on-ramp. Based on two criteria, local velocity variation patterns and expansion (or nonexpansion) of congested regions, three distinct congested traffic states are identified. These states appear at different levels of the upstream flux and the on-ramp flux, thereby generating a phase digram of the congested traffic flow. Observed traffic states are compared with recent theoretical analyses and both agreeing and disagreeing features are found.
我们分析了来自包含一个有效入口匝道的高速公路路段的交通数据。基于局部速度变化模式和拥堵区域的扩展（或不扩展）这两个标准，识别出三种不同的拥堵交通状态。这些状态出现在不同水平的上游流量和入口匝道流量处，从而生成拥堵交通流的相图。将观测到的交通状态与近期的理论分析进行比较，发现了一致和不一致的特征。
