Abstract
This study presents enhanced collision detection model in a Vessel Traffic Services (VTS) area. The proposed detection method of collision situations is based on the assumption that VTS station is provided with passage plans of all the vessels in a monitored area. By using an early detection model for prediction of possible collision situations, VTS stations could switch from the area-monitoring concept to the passage-monitoring system. An early detection model of collision risks in a VTS area uses vessels’ dynamic characteristics as inputs (vessels’ position, course over ground and speed), and delivers prediction of their future positions as output. In order to achieve the desired accuracy, the model takes into the account the intended course alterations and the impending environmental loads. The model is able to provide the outputs as early as the passage plans are submitted to a VTS monitored area. Hence, when discussing model’s capability for early detection of collision situations, improved VTS operating standards could be developed in order to achieve safer passages through enhanced collision avoidance strategies. Simulation results clearly show the advantages of the proposed model as a decision support tool for a VTS operator when combining passage plans with the analysis of environmental loads.
Highlights
The number of merchant fleets is increasing together with the immense traffic flows and highly dense maritime traffic within main ports and corridors
This is achieved by integrating messages containing relevant data from Automatic Radar Plotting Aid (ARPA), Automatic Identification System (AIS), Electronic Chart Display and Information System (ECDIS), Closed-Circuit TeleVision (CCTV), Very High Frequency (VHF), compass and other devices used for safe navigation
This paper proposes a proactive approach to maritime traffic control based on the passage plans and dynamic data received from vessels before reaching the monitored area
Summary
The number of merchant fleets is increasing together with the immense traffic flows and highly dense maritime traffic within main ports and corridors. In order for the VTS to be effective in monitoring traffic situations, it is important that the service has an option of generating, receiving, processing and broadcasting important navigational information This is achieved by integrating messages containing relevant data from Automatic Radar Plotting Aid (ARPA), Automatic Identification System (AIS), Electronic Chart Display and Information System (ECDIS), Closed-Circuit TeleVision (CCTV), Very High Frequency (VHF), compass and other devices used for safe navigation. This paper proposes a proactive approach to maritime traffic control based on the passage plans and dynamic data received from vessels before reaching the monitored area. This allows VTS operators to evaluate passage plans and detect close-quarter situations by using proposed early collision situations detection model. Detection of collision situations in congested traffic areas based on this approach has the significant potential for the improvement of the navigation safety and preservation of the environment
