Method for Prediction of Ship Movement Time in Harbor Area using AIS Data

摘要

The present invention proposes a method of calculating the vessel moving time using AIS data in order for the VTS controller to calculate the moving time of a vessel entering and leaving for an objective and accurate prediction, and based on this, a specific port enters and departs in a certain period in the past The arrival and departure transit times of the ships were calculated. By analyzing the calculation results, it was confirmed that the arriving ships preferred to dock in the departure posture and the transit time of the ships berthing in the departure posture was shorter than that in the porting posture. In addition, since the time required for arrival is longer than the time required for departure, it was confirmed that when there are many incoming and outgoing ships, it is possible to improve port efficiency by first arranging outgoing ships. The prediction method of the present invention may be actively utilized for the control of incoming and outgoing ships based on different analysis results for each port.
