AIS情報を用いた自動避航操船評価用シミュレーションシナリオ生成に関する一考察

抄録

Interest in autonomous vessels has increased, and efforts to realize autonomous vessels are underway in Japan. One of the most important issues for the realization of autonomous vessel operation is the automatic collision avoidance navigation. Simulation is an effective method for developing such an algorithm, and this paper discusses the generation of a simulation scenario that takes into account the navigation area by using AIS information, which is traffic flow data in actual sea areas. First, using the entrance of Tokyo Bay as the target sea area, the characteristics of the sea area were determined by analyzing AIS data. Next, the procedure for creating a simulator scenario by extracting congested traffic flows from the AIS data was confirmed, and by using indices such as TCPA, it was possible to create a scenario that eliminated the subjectivity of the creator.
