The Relation with Width of Fairway and Marine Traffic Flow

Seong Y., Jeong J. S., Park G. K.

TransNav : International Journal on Marine Navigation and Safety of Sea Transportation

2012

Vol. 6, no. 3

317--321

Nowadays, many of changes have arisen in maritime traffic due to the enlargement of ship’s size and improvement of ship’s speed. It is common that the risks of handling a ship in narrow water area is increasing according to increase traffic volume. In order to correspond to these changes and risks, it should be necessary to make sure the relation between proper width of route in fairway and allowable traffic volume. The conventional method of designing a fairway takes into consideration of movement by one ship of maxi-mum size. But the congestion by traffic volume is not taken in the concept. In a while, a case of road design is generally considered about a traffic volume. From such a view point, this research proposes the method of de-termining fairway-width in consideration of traffic flow. To evaluate traffic congestion in a route, the Envi-ronmental Stress model is adopted as the index of standard, using traffic simulation with avoiding a collision for reproducing traffic flow.

Fairway Navigation – Observing Safety-Related Performance in a Bridge Simulator

Nilsson R., Lützhoft M., Garling T.

TransNav : International Journal on Marine Navigation and Safety of Sea Transportation

2008

Vol. 2, no. 1

17--21

This paper proposes an approach of measuring navigation performance using a full mission bridge simulator. The motivation for this research is the updates in equipment and that the desire of using new instruments and technology not always is accompanied by analyses of the impact of the changes. The task of navigating in a fairway is proposed to be assessed through various methods to answer questions related to performance and the experience of using bridge equipment. The overall aim is to reach a higher degree of understanding and knowledge through the testing of different instrumentation setups.
