There are still much manual works during the process from collecting marine traffic data to their analyses. Authors applied a personal computer, a daylight radar and the techniques of graphical processing to marine traffic survey in order to reduce the manual works. The following results were obtained. (1) The application of a personal computer to the marine traffic observation is much effective on the simplification of the collection of traffic data. (2) The system combined with the daylight radar and the video tape recorder fairly reduced the time for the analysis of ship's paths. (3) The improvement of the graphical processing techniques using personal computer showed the possibility of the automatic analysis of ship's paths.
