A “Vessel Traffic Service” (VTS) is a shore-based marine traffic management system implemented by a competent authority to monitor vessels in real-time to enable the safe and smooth management of traffic in a specified maritime area. It performs tasks similar to air traffic control systems for aircraft. VTS checks the position of vessels and detects situations that pose danger to the vessel crew and the environment. VTS aims to improve the safety of navigation in and around the ports and its approaches. It is governed by SOLAS (Safety of Life at Sea) Chapter V Regulation 12 along with the guidelines for Vessel Traffic Services, and came into force on 1 July 2002.
