摘要： 引入几个表示流量和占有率之间关系的方法，作为一天中交通状态随时间变化的指示器，并且使用微波检测数据展现他们之间的相关关系，并指出在高峰小时或拥挤小时，流量与占有率之间的关系与其他时段显著不同，通过定义交通拥挤时段和拥挤小时以区别于交通高峰小时.增加分辨交通状态的能力.

关键词: 定量分析, 高峰小时, 拥挤小时, 拥挤时段

Abstract: This paper introduces several methods to depict the relationship between flow and occupancy, as the indicator of traffic status changing with time during one-day, and presents their correlation with microwave detection data. It points out that during rush hour or congestion hour, the correlation of flow-occupancy is different from other periods significantly. Moreover, by the definition of traffic congestion hour or period, different from traffic rush hour, the capability of identifying traffic status increases.

Key words: Quantitative analysis, rush hour, congestion hour, congestion period
