Słowa kluczowe: probabilistic model, safety of navigation, vessel traffic flow, Świnoujście approach

Abstrakt: The paper presents an analysis of ship traffic using the port of Świnoujście and the problems associated with modelling vessel traffic flows. Navigation patterns were studied using the Automatic Identification System (AIS); an analysis of vessel traffic was performed with statistical methods using historical data; and the paper presents probabilistic models of the spatial distribution of vessel traffic and its parameters. The factors that influence the spatial distribution were considered to be the types of vessels, dimensions, and distances to hazards. The results show a correlation between the standard deviation of the traffic flow, the vessel sizes, and the distance to the hazard.These can be used in practice to determine the safety of navigation and the design of non-existing waterways and to create a general model of vessel traffic flow. The creation of the practical applications is intended to improve navigation efficiency, safety, and risk analysis in any particular area.

Słowa kluczowe: Maritime Traffic Engineering, Vessel Traffic Flow, Port Areas, Multiple Regression Model, Fairway, Fairway Parameters, Automatic Identification System (AIS), AIS Data

Abstrakt: The paper presents the method of determining ships traffic stream parameters by means of regression method. The aim of the studies was to determine the correlation between the ship’s parameters and the parameters of the fairway. Developing the presented model with information on the position of the vessel’s antenna and information on the accuracy of position determination will allow creating a model for predicting the parameters of waterways.

Tytuł: Modelling the lateral distribution of ship traffic in traffic separation schemes

Autor/Autorzy: Agnieszka Nowy, Lucjan Gucma

Miejsce publikacji: Scientific Journals of the Maritime University of Szczecin

Rok: 2018

Słowa kluczowe: vessel traffic streams, ships’ traffic flow, safety of navigation, probabilistic model, traffic separa-tion scheme, modelling

Abstract: This paper presents the method used for the creation of ship traffic models in Southern Baltic Traffic Separation Schemes (TSS). The analysis of ship traffic was performed by means of statistical methods with the use of his-torical AIS data. The paper presents probabilistic models of ship traffic’s spatial distribution and its parameters. The results showed that there is a correlation between the standard deviation of traffic flow and TSS lane width that can be
used in practical applications to ensure the safety of navigation; improve navigation efficiency, safe-ty and risk analysis in given area, and for the creation of a general model of ship traffic flow.

Tytuł: Verification of automatic drift calculation accuracy using an automatic radar plotting aid

Autor/Autorzy: Wiesław Juszkiewicz, Agnieszka Nowy

Miejsce publikacji: Scientific Journals of the Maritime University of Szczecin

Rok: 2016

Słowa kluczowe: IMO performance standards, automatic drift calculation, ARPA, safety of navigation, radar simulator, radar picture stabilization

Abstrakt: One consideration required in the resolution concerning radar and automatic radar plotting aid (ARPA) equipment is the possibility of an automatic drift calculation being realized in the base of fixed target tracking. This information is very important to providing safe navigation, especially in restricted areas. This paper presents an analysis of the present regulations contained in IMO resolutions and the results of an experiment conducted in the ARPA simulator. The aim of the simulations was to verify the reliability of the information presented on the ARPA display and to determine the accuracy of the automatic drift calculation implemented in the simulator.
