摘要

著者らは船舶交通流を船舶エージェント集団によrnる複雑系と捉え、その集団行動を再現する自律型のrn船舶群行動モデルの提案、モデルの表現特性やモデrnルの改良、モデルの応用、浦賀水道航路rnを中心とした東京湾の海上交通流の再現などrnの研究を行った。そして、簡単な計算モデルであるrn船舶群行動モデルを搭載した自律型の船舶エージェrnントを用いて海上交通流を表現できることを示した。%This research aims at utilizing the marine traffic flow simulation based on an autonomous ship cluster behavior model for route planning. Marine traffic flow simulations were performed with various route dimensions and traffic conditions, and the route navigation characteristics of ship agents were investigated. The marine traffic flow simulation system we developed contains route dimension parameters such as route distance, route width, and route deflection angle. Also controlled by the system are traffic condition parameters such as traffic volume, number of inlet/outlet ways, entry/departure angles, approach distance, and exit run-up distance. The route navigation characteristics of ship agent groups were analyzed mainly using the group navigation energy, and the following results were obtained:rn(1) The distance of the approach section had a big impact on deviation from the intended route.rn(2) As the route width increased, the group navigation energy in the approach section decreased and that in the route section increased.rn(3) The group navigation energy of the route section increased as the route deflection angle increased.
