harbor based on continuous input from local harbor safety committees, whose members would include pilots and other frequent users of local waters. The safety committees would make recommendations to the USCG regarding system 2 Although AlS has only recently become a popular initiative in certain areas in the United States, it has a long history of promotion, development, and testing in the international maritime sector.

The system helps mariners avoid collisions and groundings, assists in planning safe passage, and enables mariners to ascertain the drafts their vessels must maintain when transiting ports and waterways. Nautical charts show only minimum charted channel depths, but mariners need real-time water depths corrected to allow for changes caused by severe weather or abnormal tides.

AIS can also be combined with radar or VTS systems, depending on local needs and choices.4 Universal requirements for the carriage of AIS transponders cannot be implemented until an agreement has been reached on standards and requirements.5 In general, this emerging technology appears to meet the vessel traffic management needs in many situations and will probably be adopted more widely 4 The various technological tools available for, and used in, VTS installations are discussed in the committee's interim report (NRC, 1996)

The PAWS S approach envisions traffic management as a five-stage hierarchy, with traditional aids to navigation providing the most basic safety baseline. At the next level, which provides additional security and controls, is vessel-to-vessel AIS.

Other factors, which have been identified elsewhere, should also be taken into account (National Dialog on Vessel Traffic Services, 1997~. First, many waterways do not require a VTS to achieve an appropriate level of safety.

. established Guidelines for Vessel Traffic Services7 and Guidelines for the Recruitment, Qualifications and Training of Vessel Traffic Service Operators.8 It has also defined VTS as "a service implemented by a competent authority, designed to improve safety and efficiency of vessel traffic and to protect the environment.

The second is to provide vessel traffic management and funding in areas where the national interest would be served by VTS. Although arguments can be made for individual states assuming the role of competent authority for VTS systems that operate wholly within their waters, maritime safety is best served in a consistent operating environment among ports and among nations.

The Hampton Roads RNA may require surveillance, whereas the Tampa Bay RNA may require only monitoring and recording of VHF-FM Channel 13 transmissions. All federal VTS systems must support the full range of USCG mission areas, including search and rescue operations, law enforcement, and maritime defense.

From page 29... ...
The federal government is responsible for maritime safety, ensuring a consistent operating environment and compatible technologies, and enforcing regulations. Therefore, the federal government should be the competent authority for VTS systems and should provide vessel traffic management in areas where this would serve the national interest.
