Quantitative Methods of Traffic Congestion Analysis

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.
