Traffic flow in the crossing points is the important factor for the traffic capacity as well as the safety of navigation. In order to improve the capacity and safety, the time sheared control were studied at the parallel route crossing. Two control system were considered, one is the priority in order of arrival (first come first service system), the other is the signal system. In the previous report, the authors have assumed that ships navigate in a line (single line navigation), this report treated with navigating two or three abreast (parallel navigation) in the fairway. As, the arrival time distribution of large ships have a great influence on the traffic flow in the crossing points (a number of large ship arrive to control area in a short time, traffic volume exceed the crossing capacity), pre-scheduling for large ships before arriving to the control area was considered in this report. Some results of Digital Simulation are shown; (1) The effectiveness of parallel navigation are shown in the case of priority system, unallocatable ships decrease to 1/10 compared with single line navigation. (2) Pre-scheduling of large ships is very practical and useful control. In the priority system, number of unallocatable ships reduces to 1/5. (3) Priority system with pre-scheduling for large ship is most useful control. If the maximum permissible limit of unallocatable ship rate are assumed 2%, the traffic capacity of crossing point has more than 420 (ships/day/crossing point) within 10 min. mean delay time under condition of DA =10, 000 m.
