This study proposes marine traffic volume estimation method considering ship speed, a factor excluded from the existing method. Ten days of GICOMS marine traffic data from Pyeongtaek and Dangjin ports was applied to this study. As a result, converted traffic volume with the proposed estimation method showed an increase of 4.41 (${\pm}0.99$) times or decrease of 0.59 (${\pm}0.04$) at most, compared with the existing estimation method. Average marine traffic congestion for each time applying the proposed estimation method showed an increase of 1.43 (${\pm}0.10$) compared with the existing estimation method. The maximum marine traffic congestion for each time was 1.62 (${\pm}0.34$) times higher compared with the existing estimation method. Marine traffic peak time, defined as the highest point of marine traffic congestion, was evaluated to be different from that of the existing method because of distribution of vessel speed. In conclusion, considering ship speed is necessary when estimating marine traffic volume to produce a practical estimate of marine traffic capacity.

As the marine traffic thickens all over the world, the rate of marine casualities is on the increase, Also in Korea the number of the killed and the injured resulting from marine casualities such as ship's collision, increase continuously and the rate of marine casualities in 1992 came to the highest level in the world. The reason of rapid increasing the rte of marine casualities is the mistake of ship's steering in most case. By the way, because the administration of marine traffic is regarded as the belongs of land traffic, the scope of application in laws related to the safety of marine traffic is duplicated or unreasonable. In the view, in case of ship's collision, it is important to know the scope of application in Korean marine traffic laws and to point out the problems companies with them. Therefore, I suggest the improvement of marine traffic laws related to the safety of traffic administration.

Vessel traffic safety management means the managerial technical measures for improving the marine traffic safety in general terms. The main flow of vessel traffic safety management is that: 1) Traffic Survey, 2) Replay by Marine Traffic Flow Simulation, 3) Quantitative Assessment, 4) Policy Alternatives, 5) Prediction·Verification. In the management of vessel traffic safety, it is most important to establish assessment models that can numerically estimate the current safety level and quantitatively predict the correlation between the measures to be taken and the improvement of safety and the reduction of ship handling difficulties imposed on mariners. In this paper, the replay model for traffic flow simulation was made using marine traffic survey data, and the present traffic situation became replay in the computer. An attempt was made to rate the current safety of ports and waterways by applying the Environmental Stress model. And, as a countermeasure for traffic management, by taking of, the promotion of total traffic congestion in early morning rush hour, the correlation between traffic control rate and the reduction in ship handling difficulties imposed on mariners was predicted quantitatively.

Saigon-Vungtau fairway is the main and the most important fairway of the major economic areas: Ho Chi Minh City, Dong Nai Province and Ba Ria-Vung Tau Province in Vietnam. In last 5 years, 80% of accidents happened on the fairway were caused by collision and contact/impact. This presentation study on marine traffic investigation in the adjacent of the fairway to find out problems related to marine traffic for improving Marine Traffic Safety Management in this area.

In Vessel Traffic Service, the management information on marine traffic control is almost transported by VHF. It is so difficult to exchange a lot of the related information necessary for marine traffic control exactly and in real time. Aiming at improved visualized data transporting network, we examine the methods for transporting and displaying the data on marine traffic controls. In this paper, we design the information networks established by broadcasting method and by internet method using home page in order to manage marine traffics in Masan port.

Maritime traffic engineering is a technical field that observes the flow of vessels' traffic in accurate and describes the feature of ship's movement statistically, then contributes for the improvement of traffic flow and the safety of traffic. The flow of marine traffic can be controlled by carrying out assessment and analysis of vessel's traffic. It can realize the safety of marine traffic by accurate research and analysis of vessel's traffic, understanding its flow and analysis data of vessel traffic. This study shows the analysis system of marine traffic connected with Radar, AIS based on ENC(Electronic Navigational Chart). The marine traffic analysis system contributes to the safety of marine traffic through the design of marine traffic route, harbour facilities and improvement of vessels' traffic flow.

In the present maritime traffic conditions of mokpo harbor, there exists many hazardous factors which may lead to huge accidents including marine oil pollution We analyze marine traffic environments including traffic congestion, natural conditions, maritime traffic accidents of the last 10 years, the fishery status, operation of traffic routes and navigational aids of navigational aids and regulations relating ships' routeing both in and out of the country. Consequently, this work is to propose improved marine traffic system in future.

We carried out the maritime safety audit for Sandal Water Bridge constructed between Geje-Do and Sandal-Do in 2015. To study as to whether can be secured the marine traffic safety for this area, this research investigated and performed the marine accident, marine traffic volume, the marine traffic flow simulation and shiphandling simulation. It is considered to be required the quantitative guidelines for maritime safety audit including audit target area and formal audit object etc.
