In order to provide for the safe and expeditious passage of maritime traffic in congested waters, the U.S. Coast Guard is authorized by the Ports and Waterways Safety Act of 1972 to establish, operate, and maintain Vessel Traffic Services (VTS) where needed. In larger areas, a VTS will generally require a communications system to enable the vessel traffic center and the participating vessels to exchange information. In designing such a system, it is necessary to assess the expected communications loading in order to determine frequency requirements and evaluate alternative configurations for the system. Here, VTS communications are viewed as a queuing system. Three classes of messages are considered in the arrival process: check in/check out (basic VTS) messages; Vessel Movement Reporting System )VMRS) messages; and bridge-to-bridge messages.
