The type ticket informs the bus of the need to get off the bus. Therefore, the bus can decide whether to stop at the stop 2 according to the passenger condition of the next station and the passenger's drop-off demand. In addition, if the bus 3 is at the stop 2' The receiving station 2 has a message that the passenger is waiting for the bus. However, the number of people on the bus 3 is full, and the bus 3 knows that the other bus 3' is empty from the station 2', so the bus 3 does not carry the station 2 Multiply And so the bus 3 'to the stop sign 2 support, of course, stop sign 2 will be displayed on the screen corresponding to the bus 3' department after how much time to reach the stop sign 2, in order to avoid passengers worried about their take less than a car.

On the other hand, all buses will pass the traffic conditions, bearing status, bus and driving health status of the road to the stop sign when passing through the stop signs, and the respective stop signs 2", 2' and 2 will be relayed again. The method of transmitting the status of the bus and the messages received by the stations to the Transport Control Centre 4 to generate the transport records, ie the transport records of the entire intelligent mass transit system, which can then be transmitted to the stations via the long-haul communication network. 2", 2' and 2 or transmitted by short-range relay, so each station collects all information, messages or conditions received to generate traffic status information and displays it on the stop sign, as shown in Figure 3, stop sign 2 shows how long the specific bus arrives at the station.

Furthermore, the passenger can output the destination message to the sensor on the vehicle through his smart ticket 1 or button 28 on the bus or through the smart ticket on the bus, and the bus or the bus is used for The stop sign receives the transport record message transmitted by the transport control center 4, so it can provide the passengers when they arrive at the destination and how to get to the destination. For example, take a bus to the station and transfer to another bus or transfer. The MRT can reach the destination and other related information. In short, if the passenger outputs the destination message on the bus, the bus can receive the relevant information of the destination to the passenger when the bus passes the next stop or the next stop.
