현재 2011년 10월 개통 목표인 경인 아라뱃길의 기반시설 공사에 일환인 영종대교 주변 수역에 선박 통항로가 재설정될 예정이다. 영종대교의 주변 수역에 설정될 통항로는 항로폭이 협소하고, 영종대교 주교각에 충돌방지공이 아직 설치되어 있지 않으며, 직선항로가 충분히 확보되어 있지 않은 상황에 있다. 이 연구에서는 영종대교 주교각에 충돌방지공이 설치완료되기 전까지 선박통항의 안전을 도모하기 위한 통항로의 통항 규칙 및 비상대응 매뉴얼을 제안하고자 한다.

Marine traffic system is composed of ship, ship's operators and traffic environment The navigation channel is a part of traffic environment and the design of channel is a crucial factor for safe navigation This paper aims to evaluate ship-handling difficulty in straight and bend channels with an Environmental Stress model(ES-model). The ES-model is used to evaluate ship handling difficulty quantitatively on the basis of the ship operator's subjective judgement for safety in navigation The calculation of ES value was made on the basis of three factors such as channel width, ship's length and speed in straight and channels for safe navigation. The interrelation between factors was analyzed and reasonable design standards of channel width, ship's length and speed were proposed for safe navigation of ship in bend channel.

In the present maritime traffic conditions of Gwangyang harbor, there exists many hazardous factors which may lead to huge accidents including marine oil pollution. To mitigate the danger to vessels in Gwangyang harbor and to secure the safety of maritime environment, we established one way traffic between No.3 Route and No.4 Route, Designed of deep water line on No.3 route, Extended one-way route for Myo-Do Passage etc.

Route Design & TSS(Traffic Separation Scheme} establishment are often used to improve the maritime traffic safety in the heavily congested traffic area. There are several domestic and international route design guidelines, but there is no guideline of TSS design As a result, TSS is usually designed based on the subjective opinions of professionals in this field. Until now, there exist a few papers dealing with the effects of TSS on the reduction of maritime accidents, however, it is hard to find a paper on the design guidelines of TSS. In this paper, TSS design guidelines are proposed based on the quantitative assessment of navigational difficulty felt by mariners, which is expected to improve navigational safety of vessels in congested area.

Route Design & TSS(Traffic Separation Scheme) establishment are often used to improve the marine traffic safety in the heavy waters. There are several domestic and international route design guidelines, but there is no guideline of TSS design. So, TSS is designed by specialist's subjective opinion. Until now, when TSS is designed there are a few paper about the easiness effectiveness of marine accident, but there is no paper to design TSS guideline. This paper proposes the design guideline about TSS to improve the safety of navigation vessel by the quantitative assessment in the viewpoint of mariner.

This research presents an analysis of algorithm for ship track-keeping along a given trajectory. The maneuver of a free running model ship guiding through a simple path are presented. In order to solve the above problem, a desired trajectory is usually determined by GPS points in a pre-fixed place then these points are set in a pre-programmed navigation so that the ship would be automatically tracked. Proportional-Derivative(PD) control which is useful for fast response controllers was used in this program as a course keeping system. A high accuracy GPS receiver was installed on the model ship that could provide positions frequently, the system will compare and give out the remaining distance and heading to the target way-point. The results of ship auto track-keeping experiment will be explained in order to illustrate the adjustment in controlling parameters. These results can be utilized as a preliminary step to carry out the experiment of ship collision avoidance system and automatic berthing in the future.

In this paper, We explain the development of helicopter avation information system which provides the current location and other pre-saved informations in order to guarantee the safe aviation. The system we developed has the functions such as displaying digital map data and current location, route planning, displaying the rate of deviation, calculating and displaying the cross sectional view through the route and providing a real-time speed, heading and other informations. In this system, we use GPS to get the current location, made the 1:250,000 digital map to display the current location and made the cross sectional view from the DEM(Digital Elevation Mode)) data to help safe aviation. This system provides many kinds of route setting methods by using UTM coordinates, Lati. Longi, coordinates, database of heliport location, scanned map, etc., and displaying the heading and distance. Moreover, it also has a characteristic of providing a consistent user interface.

부산신항의 출입구라 할 수 있는 가덕수로 남단 해역에 해운불경기 등으로 인하여 불법, 무단으로 투묘한 선박들이 증가하면서 인근 해상에서 충돌사고 등을 야기할 수 있는 위험성이 증가하고 있다. 본 연구에서는 장기투묘 선박들로 인한 위험요소와 문제점들을 살펴보고, 이를 해결하기 위한 방안으로 가덕수로 항로를 외곽으로 연장하는 접근항로를 설정 운영하는 방안을 제시하였다. 이와 함께 VTS 연계망을 유기적으로 구축하여 남동부 연안해역의 해양사고 위험성을 감소시키고 동 해역을 효율적으로 관리하는 방안을 제안하였다.

Traffic risks in fairway and harbour area increase lately according to be a sharpe change of ship's size and speed. It becomes hot issue to design a fairway, which's width is important to lower traffic risk and ensure navigational safety. The current design making a fairway and width do not focus on maneuvering motion of a large ship, but traffic risks are clear on reflecting the design of fairway, specially on width. To contact with these problems, this research proposes how to determine fairway' width in consideration of traffic volume. it suggests several situations of marine traffic congestion as like narrow channel and harbour area. here uses 162 simulations in MTS Ver.1 developed. Acquired simulation's results, environmental stress dates, figure in a model that relates with required fairway' width and allowable traffic volume. In added, suggested model compares current design with an width.

Currently, ECDIS and GPS plotters are much used as equipment providing operators with route information, but they do not have any function of automatic route creation and route explanation, so available for only experienced operators. Especially, the present situation is tint no study is made of the automatic route creation and route explanation using ENC for ECDIS, substitution system of paper chart. ENC is the electronic navigation chart that is produced using S-52, S-57 standard format required by IHQ. In this paper, an Vessel Operator Support System(VOSS) is proposed to generate an optimal route where ENC and GPS data is fusioned induding the wind direction and speed of an anemometer and tide data. The proposed system was testified by a simulation, and its effectiveness was verified.
