Procedure for Marine Traffic Simulation with AIS Data

Miyake R., Fukuto J., Hasegawa K.

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

2015

Vol. 9, no. 1

59--66

It is essential to evaluate safety of marine traffic for the improvement of efficiency and safety of marine traffic. Spread of AIS makes observation of actual marine traffic more easily and faster than before. Besides, description of collision avoidance behaviours of ships are indispensable to simulate a realistic marine traffic. It is important to develop and implement an algorithm of collision avoidance corresponding to a target traffic or target area into the marine traffic simulation because actual actions for collision avoidance depend on circumstances where ships are sailing. The authors developed an automated marine traffic simulation system with AIS data. And in this paper, we proposed a series of systematic procedures for marine traffic simulation including analysing for collision avoidance behaviours using AIS data.

Marine Traffic Real-Time Safety Index

Xu T., Hu Q. Y., Xiang Z., Wang D. L.

599--603

To reflect the safety degree of marine traffic in real-time and intuitively, this paper put forward a concept of real-time safety index of marine traffic, established marine traffic real-time safety index system, and constructed a real-time safety index evaluation model by using vessel traffic and navigation environmental data provided by shore-based AIS base station network, and quantifying a variety of data which impacts the safety of marine traffic such as ships’ real-time dynamic data, weather changes and so on. A continuous real-time evaluation to a specific area was carried out in the form of real-time index curve, taking the Waigaoqiao Channel of Port Shanghai as an example, to verify the feasibility and effectiveness of marine traffic real-time safety index.

Comparison of the Applied of Car Navigation System and Developed Marine Navigational System

Shiotani S., Liu X.

A watch officer in sailing a ship uses many kinds of navigational information to prevent marine disasters. Especially in coastal sea area such as narrow bay or port, many ships crowds and marine disasters tend to occur more often. In these regions, effective presentation of variety navigational information is very important. On other hand, a car navigation is very effective in road traffic, However, it is not used almost in sea traffic. Our objective in this paper is to apply a car navigation to ship sailing. Also, a marine navigation system proposed by us was compared with a car navigation system. In this study, authors tried some ways of utilizing car navigation technology for the sea. To improve navigational security and safety, we investigated whether car navigation systems could be applied to marine traffic. The applicability was evaluated through several comparisons of our navigation assistance device using GIS.

New Development of Ships Routeing in Chinese Navigable Waterways

Hui M., Zhaolin W., Zhengjiang Liu

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

2008

Vol. 2, no. 2

127--130

After entering 21 century Chinese waterborne transportation keep high speed development, mmarine traffic order and marine traffic safety become more important issues. In order to enhance marine traffic safety and efficiency, ships routeing systems were implemented in important navigable waters in recent years. After implementation of these ships routeing systems, evaluations on the effects are carried and prove that these ships routeing systems have got obvious effects both on safety and economic efficiency.
