Bottleneck capacity is one of the important factors to determine a scale of traffic congestion on expressway. This study examines traffic detector's data to investigate capacity reduction due to sunset. The detector's data are observed at 450 sites on Hanshin Expressway through 2 years at 5-minutes intervals, so size of the data becomes very huge. Visualization approaches are considered as one of the efficient methods to analyse such huge data.<BR>To find the sites with capacity reduction and to understand the overview of the reduction phenomena, the diagram named "Traffic Contour Map" has been developed. The diagram is depicted for every observation site, and the sites with capacity reduction are selected. Then the causes of capacity reduction are analysed by the other diagrams named "Dynamic Flow vs. Density Diagram (D-QK diagram)".<BR>This paper provides how visualization approaches would be applied to the analysis of traffic flow.
