Lateral Distribution Regularity of Ships' Sailing Positions within a Channel Based on AIS Data

摘要

In order to offer the general view and regularity of choosing right transverse position and reduce the uncertainty of choosing lateral position to the ship officers when navigating within the two-way fairway, with the theory of marine traffic engineering and data mining technology, the regularity of transverse distribution of ship' sailing position within the two-way fairway is mined and counted using the shipborne AIS data. The regularity reveals positive effect quantitatively on the safe navigation of different ships caused by the and extent of different length of ship complying with rules. The result can be used for choosing the safe and suitable transverse sailing position when the ship goes through two-way fairway and also for marine traffic organization, layout and planning of fairway conducted by the authorities.
