PURPOSE:To make the user of an omnibus to recognize the accurate scheduled departure time of the next bus by retrieving and extracting the time corresponding to the scheduled departure time of the next bus from a storing means after the elapse of prescribed time and displaying the extracted scheduled departure time of the next bus. CONSTITUTION:When fixed time elapses after the preceding omnibus a reception discrimination circuit 21 outputs a signal for retrieving a scheduled departure time table stored in a storage circuit 24 for the scheduled departure time of the next bus to a retrieval circuit 23. The circuit 23 successively compares the time table of the circuit 24 by using the arrival time of a just arrived omnibus stored in a register 22 as a reference and the content being displayed is replaced with the scheduled departure time extracted by the circuit 23, and thus, the extracted scheduled departure time of the next bus is displayed on a time displaying device 25. Since, when a route code and scheduled departure time are transmitted from a transmission circuit 12 in such way, the reception discrimination circuit 21 of a bus stop receives the code and time and the scheduled departure time of the next bus is displayed in a delayed state if the next bus is delayed, the user of the next omnibus can clearly recognize the delaying time. |
