The marine traffic safety plan was highly consolidated by the traffic separation schemes in International Collision Regulations and by the traffic methods in the traffic route and the traffic ways at the narrow channel in Japan Marine Traffic Safety Law. Corresponding to this plan, it will be reguested to newly designate the recommended route in the adjacent water area to the narrow channel or the traffic route for the marine traffic safety. The recommended route heretofore in use by Hydrographic Division, M.S.A., Japan, has the purpose of keeping safety for navigation and it had no particular significance, in preventing collision between ships, but from now on, the recommended route should discharge the function as the traffic separation line and should be lawfully connected with the mid line of the fairway at the narrow channel or the traffic route, or, if any, with the certain course designated by Notification at or near the narrow channel.
