The number of collisions where influence of the third ship is reported occupies a considerable part, about 6%, in the total. Since the number of collisions is approximately proportional to the number of encounters, as has been shown by the author and recently by Dr. Lewison, estimation of the number of multiple encounters with traffic data is tried here. Previous study shows that the number of evasive actions are well approximated with the number of overlaps of pairs of ship domains, the multiple encounter is defined here as simultaneous generation of two or more overlaps of the domains. Mathematical analysis yields a formula in which a useful index, ρ A, the product of the density and the area of a contour shown in Fig.1, is included. When ρ A approaches unity, the share of multiple encounter becomes conspicuous. The index may well serve as a criterion for determination of the traffic capacity.
