概要

This paper describes an improvement made for the expressive capabilities of the ship cluster behavior model. The goal of this study is to realize a pseudo realistic marine traffic flow analysis in the complex sea environment. The approach is based on the development of the proactive means capable of detecting obstacles and assisting safe group navigation. Specifically, two enhancements so called strategic navigation planning in a global computation phase and tactical obstacle avoidance in a local computation phase are applied to the ship cluster behavior model. The validity of the enhanced ship cluster behavior model is evaluated using computer simulations in artificially generated geographic environments. The results confirm the model's strong abilities in supporting complex traffic flow simulations. A series of experiments are also performed for the navigation of Tokyo Bay to investigate the formation of the traffic flow under varying conditions of geographic features.
