Many observations have been made in many ports and channels to obtain the characteristics of marine traffic.
There are many processes between observations and final conclusions.
Systems Lavoratory developed a method, making there processes as automatic as possible using modern electronic devices.
Using this system,
(1) We can obtain instantaniously automatic read-out drawings, some informations from which we could not have obtained otherwise.
(2) We open the way to analyzation of the characteristics of marine traffic using electronic computers.
