A Study on Basic VTS Guideline based on Ship’s Operator’s Consciousness

Abstract

VTS controls vessels using VHF for 24 hours a day. Therefore, from the analysis of VHF communication, we can understand the current status of marine traffic and VTS’s control pattern in VTS area. This study objective is to propose a basic VTS guideline with ship’s CPA/TCPA, collision risk, control frequency, and minimum safety distance using analysis of VHF communication. We analyzed a 7 day VHF communication and AIS data from Busan VTS area, thereafter calculated risk of collision using Park model which is based on ship operator’s consciousness and plotted minimum safety distance and vessel’s high-risk control frequency using Poisson distribution.
