This study estimates future marine traffic volume using a popular time series model. It is significant to predict monthly traffic volume based on converted traffic data. It is more quantitative method by applying time series models. This research can use to provide basic traffic data for a port design and proactive VTS operation by considering marine(More)
Vessels exhibiting abnormal navigation patterns (e.g., weaving in and out of courses or rotating in the same position) may have a serious impact on other vessels staying on normal courses. For this reason, ground VTS centers are keeping track of criminal vessels or damaged vessels in tandem with marine police. However, the number of available studies aimed(More)
Among navigating ships a near-miss accident means an undesired event that did not result in collision, but had a potential to do so with high risk. The assessment of near miss accidents is required to take further proactive measure for re-duction of ship collision accident, while actual accident analysis helps finding any solution to prevent future maritime(More)
Vessel trajectories data are mainly collected using Automatic Identification System (AIS) in discrete intervals of 2~180 second. In process of e-Navigation, the maritime traffic gridded database will be used by producing grid image. In order to prepare for this, this study, we apply spline interpolation to the vessel trajectories, and develop proper grid(More)
A prediction of vessels movements helps to improve safety of navigation. In an arbitrary water area, the prediction information of vessels to be encountered can be provided by observing inbound/outbound vessels for ports. This study proposes a prediction table representing leeway and arrival time at each waypoint. Given the table, the encounted vessels are(More)
In a coastal area, all of the vessels are always exposed to the potential risk, taking into the maritime accident statistics account over the last decades. To manage vessels underway safety, the characteristics of ship movements in a fairway should be recognized by VTS system or VTS operators. The IMO has already mandated the shipboard carriage of AIS since(More)
