The purpose of this paper is to describe the brief history of VTS in Korea including traffic separation scheme(TSS) and vessel movement reporting scheme(VMRS) in earlier time. The effectiveness of existing traffic services in Korean waters in mentioned in comparison with the results of other countries. Advanced VTS has been introduced in 1993 at the port of Pohang and thereafter a national VTS programme is developing to introduce the state-of-the-art system into major ports and their approaches including Yosu/Kwangyang Inchon and Pusan. This paper introduces the future expanding VTS programme is Some recommendations are made to enhance the traffic safety in Korean waters and to increase the effectiveness of the advanced VTS.

The efforts for improving 'Maritime Traffic Safety Assessment Scheme(MTSA scheme)' have continued to the present since May 27th, 2009. But recently, there's a controversy about whether it has been performed properly or the results is significant. These new discussions were arose from lack of validity and appropriateness we had yet to find. At this point, it needs to establish sound MTSA scheme through the comprehensive review. This research developed a suitable meta-evaluation model for MSTA with applying theory of the teta-evaluation, that is the evaluation of evaluations and verified by using meta-evaluation methods like as literature studies, expert reviews, surveys and etc. The results of this study can be used to evaluate MTSA activities and it will contribute to improving MTSA scheme.

In order to reduce maritime accidents and promote maritime safety and the happiness of the sea people, the Ministry of Oceans and Fisheries has been providing Intelligent Maritime Traffic Information services to the public from the end of January 2021. Various information is generated and collected through this service, and research and development is underway to develop and verify a service algorithm by applying the collected information to data science to realize a safer and more efficient intelligent maritime traffic information service. In order to develop and implement this, a data pipeline system that connects the collected and stored data and can access, use, and store data from multiple systems smoothly is required. Therefore, in this study, a data pipeline that can be used in various systems such as a datascience based service algorithm development environment and an intelligent maritime transportation service test-bed was designed.

There are enormous challenges in the Istanbul Strait- one of the most important, congested and narrow waterways in the world - from the view point of risk determination and risk mitigation for the local traffic. Previously several traffic parameters such as; traffic volume for local vessels, traffic flow and potential encounters of local traffic, in addition to the possibility of collision, were investigated in order to determine the degree of dangers in the southern entrance of the Istanbul Strait. Furthermore, risky zones were also determined in this waterway. On the basis of the results of those, a group of expert was surveyed. These experts were pilots, Vessel Traffic Services Operators (VTS-O), Local Traffic Vessel Captains and Master Mariners who had several experience of navigation through the Istanbul Strait. In order to assess experts perceptions of danger and to propose further studies based on this survey. The questionnaire was analyzed by using SPSS (Statistical Package for the Social Sciences) program version 13.0. Finally, some differences and/or shares on risk perceptions of expert in the Istanbul Strait are considered.

Even if the HF band SSB maritime data communications service company has operating a target Of the member ship, because of unprepared. the radio link protocol that has been question accordance with increase of calling redundancy at traffic overload. Although free signal has operating for traffic of the next ship, but cannot avoid the collision in mutual calling ships. In feature of HF band SSB channel that radio link must be established by automatical, stability and adaptive at over load. In this factor, this paper is studied the new radio protocol by 3 step sequency driving of free access, group free access and polling access.

The vessel encounter data collected from the vessel trajectories in the maritime traffic situation is possible to analyze vessel collision and near-collision risk using statistical method. In this study, analyzing variables extracted from the vessel encounter data using factor analysis, we determine main factors effecting vessel collision risk from vessel encounter data. In order to calculate each factor, it used principal component analysis for factor analysis after normalization and standardization of vessel encounter variables. As a result of the factor analysis, main effect factors are summarized into the vessel approach factor and collision avoidance variance factor.

The total number of deaths by traffic accidents is decreasing every year in our country. However, in 2009, children died in traffic accidents at a rate of 2.3 deaths per 100,000 children, which was higher than the average of OECD countries (1.9 deaths per 100,000 children). In particular, traffic accidents are showing rapid increase in school zone during the past 2 years because of problems in the designation and management of school zone. Traffic safety facilities such as road sign, reflector mirror, speed bump have the ultimate limit of vehicle accidents prevention. Thus, in school zone, children safety is still not guaranteed due to illegal parking and the absence of driver's awareness of safety. Therefore, In order to protect children from traffic accidents within school zones, we have realized a safe school zone system, which enables the drivers to better know the intended school zones and creates pedestrian environment through unmanned monitoring camera, using LabVIEW.

The safety degree of navigation for collision avoidance is closely related with the combination between mariner's behavior and navigational environment. The condition of navigational environment is mainly decided by navigable waters, ship traffic, rule of road, sea state, weather and so on. Especially, the condition of navigable waters and ship traffic in navigational environment are ones of the important factors to attain safe navigation when mariners are underway and crossing, head on or overtaking situation. Thus this paper is to analyze the characteristics of mariner's behavior for collision avoidance caused by ship traffic and navigable waters by analyzing the contents of questionnaire and the results of international collaborative research. As a result, it can be concluded that the density of ship traffic and the area of navigable waters affect mariner's ship handling for collision avoidance.

Rapid increase of maritime traffic volume and the increase of vessel size make it indispensible for the fairway designer to estimate the traffic capacity of a fairway at its early design stage. In this paper, as one of the methods to estimate the maritime traffic capacity of a fairway, operating rate of a fairway is defined and reviewed together with its basic characteristics, which is a brief estimation model based on bumper model around a ship. The method is applied to the approach channels of major harbors in Korea to give some guidelines on the acceptable traffic capacity of a fairway. In spite of its simplicity, this method can be used as an effective tool to discriminate whether the principal dimension of a fairway is enough or not from the viewpoint of maritime traffic capacity at its initial design stage.

There has been only a deep water route for deep draft vessels without any other routeing system in Yosu Bay despite of the rapid change in ship's size and increase in the traffic volume since the specified area for traffic safety was established in 1988. In this work, we suggest several solutions to secure ship's safety and to eliminate dangerous factors which exists in present ship traffic system Consequently, this work is to propose improved marine traffic system in future.
