The prevention of marine accidents, particularly those involving ecologically hazardous materials has become a vital national concern in the past decade. The establishment of Vessel Traffic Services (VTS) by the Federal Government was undertaken to improve the safety of maritime transportation in major U.S. harbors. The existing VTS were developed using state-of-the-art technology and do not require special equipment for the participating ship which must, however, be capable of communicating on the VHF radio channels designated for this purpose. This report discusses deficiencies of current VTS technology and practices in the context of pilot navigational needs and develops a concept for the introduction of an Advanced Vessel Traffic Service (ACVTS) which would utilize a digital link to obtain ship identity and position and provide a common digital data broadcast to all participants which would give each pilot a ship-centered display of traffic in his vicinity. The concept is based upon the internationally adopted digital selective (SELCALL) signaling system for maritime communications and would utilize advanced state-of-the-art portable displays for the pilots involved. The technical feasibility of this concept is illustrated and the major technical trade-offs are developed. A scenario for CAORF simulation is developed to demonstrate the advantages of ACVTS by comparing it with current VTS and existing pilotage procedures in New York Harbor for moderately high levels of traffic.
