Most mariners feel many difficulties when they navigate in the congested sea area. These difficulties come from the collision danger with other ships on the navigation. It is important to identify the degree of congestion at the sea area, when the safety assessment of marine traffic within it is made using a simulation technique. An appropriate simulation scenario can be selected using the degree of congestion as an index of the traffic condition. There are several factors which affect the congestion at the sea area. They are a ratio of the open sea area to the total one, number of ship encounters, smoothness of traffic flow and various natural environments. In the present paper, an integrated index on the degree of congestion at the sea area is proposed. Several indices for evaluation of congestion from the view point of each factor which affects the congestion are also propesed.
