Although there are many approaches to the problem of marine traffic flow, following sequential procedure is suggested: a) Observation of marine traffic flow; b) Extraction of the characteristics of traffic flow; c) Actual maneuvering patterns used by masters, and d) Traffic flow representation and synthesis using simulation techniques. The main aim of this paper is to use this procedure and present traffic capacities quantitatively, taking into account the following peculiarities of marine traffic flow: a) The vessels range in size from several gross tons (GT) to more than 140,000. In other words, the range of vessels lengths are from several meters to more than 350 meters. b) From the viewpoint of vessel control, a single method or theory of control is not available for controlling whole marine traffic flow because the inertia and mass of vessel, the operation method, the master's experience and knowledge about vessel maneuvering, and so on, vary considerably. c) There exist many small vessels of less than 500 GT in Japanese coastal waters. They amount to about two-thirds of the total number of vessels. d) There are many congested areas in Japanese inland waters. The traffic volume in these area amounts more than 1,000 vessels in a day.
