The data processor 23 has a position data processing program, an alternation data processing program, a position data file, and an alternation data file. The position data processing program records the current positions, etc., of the respective vehicles 1 received by a base station radio communication means in the position data file and the alternation data processing program graphically display timetable data on respective alternations as a alternation table screen consisting of a set of bar graphs and also displays points on the lateral bar graphs corresponding to arrival scheduled time on the timetable for the current positions of the respective vehicles 1 as, for example, bright points. |
