The received image information and the sensing information are transferred to the converter 312b. The conversion unit 312b of the gateway 312 converts the received image information and sensing information into a higher interlocking signal for interworking with the heterogeneous networks (Optic, Ethernet, WLAN, CDMA, Wibro, etc.). The converted image information and the sensing information are transmitted to the transmitter 312a. The transmitter 312a transmits the image information and the sensing information converted into the higher interlocking signal received from the converter 312b to the receiver 351 of the base station 350.

The conversion unit 312b restores the state before the conversion, and transmits the restored image information and the sensing information to the transmitter 353. Thereafter, the transmitter 253 of the base station 350 transmits the image information and the sensing information received from the converter 352 to the congestion improvement server 360.

The congestion improvement server 360 receiving the restored image information and the sensing information from the base station 350 stores the received image information and the sensing information, and monitors the congestion of the vehicle based on the restored image information and the sensing information. Before the subway enters the history platform, the collected information is sent to the information service notice boards 371 to 374 (S603).

The notice boards 371, 372, 373, and 374 installed in the history platform receive information about the congestion of the passengers from the congestion improvement server 360 to guide the passengers to select a less congested vehicle and board the vehicle. At the same time, the concentration of congestion is dispersed and passengers are provided with convenience (S604).

The notification boards 371, 372, 373, and 374 display the congestion message 105 in three color gamuts of red, yellow, and green on the message notification board 104, assuming that there are 10 cars. From column 1 to column 10, one of the colors red, yellow, or green is displayed, red means congestion, yellow means relatively calm, and green means very calm. In other words, green color can accommodate most passengers, yellow color can accommodate half passengers, and red color can be difficult to accommodate passengers.

Passengers waiting on the history platform recognize the information on the degree of congestion of the passenger car from the notice boards 371, 372, 373, and 374 described above, and then move to the place where the passenger can ride the vehicle.

The message notification board 104 of the notification boards 371, 372, 373, and 374 may not only display a congestion degree of the passenger car but also display advertising messages at regular time intervals to obtain advertising revenue.
