Study on the man-machine system is important for automation of vessel operation. This requires a wide study on the influence of the man-machine effect in ship operation where there are large difference in size, versatile operators and various environment. The objectives of the study is to estimate the man-machine effect through statistical data in vessel traffic flows placing emphasis on the "pass time", T', through a waterway employing two kinds of traffic simulation. The pass time is represented as the specific pass time, T'/T_<0-1>, where T_0 is the pass time without evasive action. Factors which give influence to resulting distributions, such as conditions, for evasive actions are also investigated. The man-machine system is embedded in the dynamic simulation with a computer as: (1) information on the movements of vessels is obtained as a birds-eye view where a "man" is fixed to the earth (absolute coordinate). (2) information on the movements of vessels is obtained as a birds-eye view where a "man" is fixed to a vessel (relative coordinate). The result indicates considerable differences in the specific pass times for two man-machine systems as follows, where the data are averaged values of about 100 vessels. [table] Though the pass times distribute comparatively widely, differences in two coordinate systems are clearly observed and indicate the influence of the man-machine effect.
