AIS/VTS

vessel traffic service (VTS) is a marine traffic monitoring system established by harbour or port authorities, similar to air traffic control for aircraft. Typical VTS systems use radar, closed-circuit television (CCTV), VHF radiotelephony and automatic identification system to keep track of vessel movements and provide navigational safety in a limited geographical area.

Vessel traffic services deal with managing ship traffic on marine routes, suggesting best routes for a vessel and ensuring no two vessels run into each other on congested routes.

All this and much more ensures that maritime information always flows smoothly over all marine routes and ship traffic remains organized. As included by International Maritime Organization, Vessel Traffic Services also deal with making marine routes safer and more efficient.
