The paper presents problem of ships traffic flow parameters estimation and the impact of sample size (ships track based on AIS data) on estimation of general population parameters. Too many trials for each estimated point lead to prolonged study, to few trials can no ensure the desired accuracy and reliability of inference. Passages of ships under the Řresund Bridge connecting Sweden and Denmark were analyzed. The conclusions can be used as directives for researches on traffic flows on open and restricted waters.
