In order to study the characteristics of mixed vessel traffic flow, based on classical head distance model and probability analysis, by studying the combination time head way of different vessel-following sequences, the capacity model of mixed vessels traffic flow was established. Through analyzing two representative types of vessels, research results indicate that the capacity of mixed traffic increase with the traffic flow speed in a certain speed range, but the increasing trend slow down. The closer length and inertial stopping distance of different kind vessels are, the more capacity of mixed traffic increases. And the influence of reaction time on the capacity is related to proportion of different kind vessels.

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.

This article aims to analyse the statistical parameters of waterways forming the entrance to the port and the construction of a model for determining the optimum parameters of the entrance to the port. It has been analyzed parameters of the entrances to the 100 selected global ports, based on the analysis it was examined the interdependence between certain parameters and the impact they have on the maximum size of the ship which can enter to the port. This analysis allowed to develop a model, which can possible to be applied to the entrance of initial port design.

Przeanalizowano różne kryteria oceny bezpieczeństwa statku na torze wodnym przy oddziaływaniu silnego prądu poprzecznego. Zjawisko okazało się złożone ale możliwe do ujęcia matematycznego. Modelowanie zjawiska i symulacja zachowania się statku w różnych warunkach otoczenia powinno dać wskazania dla projektowania nowych bezpiecznych parametrów torów wodnych i konstrukcji hydrotechnicznych oraz zweryfikowania przepisów lokalnych dotyczących już istniejących torów. Zjawisko będzie najwierniej odzwierciedlone przy zastosowaniu trójwymiarowej domeny statku i trójwymiarowych map elektronicznych. Powyższe badania można rozszerzyć o wpływ większej liczby zakłóceń zewnętrznych oraz opracowanie szczegółowego modelu zachowania się statku. Praca ta będzie przedmiotem dalszych badań autora.

One analyzed different evaluation criteria of the safety of the ship on the fairway at the influence of the transversal strong current. The occurrence proved composite but possible to the mathematical seizure. The modeling of the occurrence and the simulation of the comportment of the ship in different ambient conditions should give indications for the designing of new safe parameters of fairways and engineering constructions and verifying of local regulations concerning already existing tracks. The occurrence will be most retentively reflected at the use of the three-dimensional domain of the ship and three-dimensional electronic charts. Above research can be extended for the influence of the greater number of external disturbances and the elaboration of the detailed model of the behavior of the ship. This work will be a subject of further research of the author.
