航路体系設計手法の開発-II : 交通環境評価への適用

Abstract

In the previous report, the new investigation method on the marine traffic condition was proposed. The main structure is that the marine traffic situation is analyzed from view point of the effect of the factors that compose the marine traffic. In this report, the way of estimation for the real marine traffic condition using the proposed analyzing method is discussed. The contents of estimation are follows; 1. The form of fairway which means ship's track, the traffic density, ship's length and ship's speed are selected as they are main factors of traffic condition. 2. The traffic form is classified into three types, crossing fairway, merging fairway and converging fairway. 3. The real traffic density, the ship's length and speed are examined for every classified fairway type and the evaluation values are calculated using the stock data. The real traffic condition are estimated using the above standard procedure. We got the satisfied results. Furthermore when we need more exact estimation for the local area, it is possible to improve the estimation accuracy as a result of taking account of the influence affected by crossing point or merging point to the surrounding area.
