航路航行交通流と設計指針に関する基礎研究

Abstract

This research aims to obtain traffic route design guidelines based on marine traffic flow characteristics. The traffic route design guidelines were obtained from the result of simulation using a ship cluster behavior model which is able to emerged marine traffic flows based on the interaction of ship to ship and ship to route. The marine traffic flow simulations were performed with distance, width, deflection angle of traffic route, approach distance, exit run-up distance, number of inlet/outlet ways and traffic volume. The simulation results were analyzed using the group navigation energy and frequency of near miss. Fourteen traffic route design guidelines were acquired. Some design guidelines are shown below. ① Interaction between ships on the two-way traffic route is larger than that between ships on the one-way traffic route. ② When the approach distance is short, a near miss occurs and the interaction level between ships also increases. ③ There is a minimum required approach distance for navigation safety. ④ If the route width can be set up widely, the interaction level of an approach domain can be decreased.
