为实时监测武汉市过江桥隧的交通运行状况，对ETC流量分析子系统开展研究。以速度-流量模型为基础，基于浮动车和ETC过江流量数据，综合考虑流量和速度两项指标，分别确定其等级划分标准。在此基础上构建交通运行分析色谱图，避免了采用单一流量指标可能出现的运行状况错误判断。武汉市的应用结果表明，该色谱图能为实时监测道路运行状况、分析道路异常情况、定量分析道路实际通行能力及畅行速度提供直观、有力的技术支撑。

In order to monitor real-time traffic operation of crossing river tunnels in Wuhan, this paper stud-ied and developed the ETC flow analysis subsystem. Based on speed-flow diagram along with the floating car and ETC data, the paper analyzes traffic flow and speed indicators and proposes the corresponding cate-gorization criteria. To avoid errors in traffic operation identification that solely depends on the flow indica-tor, the paper develops a traffic operations analysis chromatogram. Analysis results show that the chromato-gram provides technical support on real-time road operation monitoring, road traffic incident and conges-tion detection, and quantitative analysis of traffic capacity and free flow speeds.
