| Abstract: | The theories of mathematical statistics and probability theory are used to define the ratio betweenthe length of confidence interval and the average estimation of daily traffic volumes as the relative error,some conclusions are drawn on relations between the number of observational days and the accuracy on theestimation of traffic volume. These conclusions may be applied to the harbour planning, establishment ves-sel traffic separation scheme, and the determination of the numbers of exchanger on shore-based radio sta-tion. |
