Vessel traffic service

A vessel traffic service (VTS) is a marine traffic monitoring system established by harbour or port authorities, similar to air traffic control for aircraft. In the United States of America (USA), VTSs are established and operated by the United States Coast Guard (USCG) Navigation Center. Some VTSs in the USA operate as partnerships between USCG and private agencies. 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.
