VTS and maritime traffic planning - Subscriber Access Only

By BCShippingNews 05 October 2016

As maritime traffic grows in busy waterways, ports and vessel traffic management authorities face increasing challenges to maintain the safety and efficiency of vessel movements. Higher volumes, larger vessels, environmental and safety concerns and competitive pressures are all contributing factors.

Traffic management technology can play a major role in assisting the responsible authorities to address those challenges by allowing them to realistically model and schedule vessel movements well in advance, and more effectively support the Vessel Traffic Services (VTS) function.

Vessel traffic systems technology

The available technology for monitoring vessel movements has become highly sophisticated. Products such as Saab’s V3000 VTMIS platform merge AIS data with ground-based radar data to provide a highly accurate, real-time picture of vessel activity. Software modules analyze traffic data to ensure that vessels are following their recommended sailing plans, and to predict potential conflict or accident situations, by extrapolating their course and speed and combining that information with tide, current and meteorological data.

In most traffic areas, however, vessel scheduling for traffic management purposes is minimal or non-existent. Decisions about traffic priorities, i.e. who should proceed first into a narrow channel, are done on a first come, first-served basis, or co-ordinated via VHF communications among the vessels’ pilots and bridge officers. In some particularly restricted areas, local rules may be in place to smooth the process, but they are typically still applied on a near real-time basis to a very limited area.
