PURPOSE:To provide the arrival time system which can estimate the scheduled arrival time of a vehicle. CONSTITUTION:Three vehicles A-C are existent in plural areas divided like the checkers. In such a state, the scheduled arrival time from each vehicle to all the areas is calculated with the vehicle side (departure area) as a reference first of all. Next, the scheduled arrival time of the vehicle to first arrive at the area is calculated with each area as a reference. Concretely, assuming that attention is paid upon an area 1-I, time TA-TC calculated by adding departure enable time alphaA-alphaC of the respective vehicles to moving time tA-tC of the three vehicles calculated in this process is sorted, the earliest time is defined as the scheduled arrival time for the area 1-I, the scheduled arrival time is similarly calculated for each following area, and the respective results are stored in a memory. Then, by displaying each time through a display device or the like, it is possible to immediately answer the inquiry of the arrival time. |
