In this paper, we applied our digital simulation method to the estimation of traffic capacity in a ship's channel system having a crossing part as Fig.1. In the crossing part which might give the most important influence to this capacity, we adopted fundamental navigation rules as followed. Those were ; (1) firstly that the ship under navigation in the main channel had to be given higher priority than the ship in the sub-channel, (2) and moreover that the above ship in the sub-channel had to take her rudder or use her engine to leave a enough sea room in time and place for the ship in the main one. According to our results, we could estimate that the traffic capacities in the cross type channel system were about 36, 19 and 10 ships per one hour in the sub-channel, when the mean penetrating ships into the main passage were 15, 30 and 45 ships per one hour, supporsing that all ships were standardized to the 73 meters length ship which was a predictive value of ship's distribution of 1985 judging from 1973.
