The MCU 112 can determine the number of passengers boarding the vehicle at the current time based on the passenger disembarkation information provided from the boarding and disembarking detection device 1000, and based on this determination, the first LED 132 module can be controlled so that the determined number of passengers is visually displayed.

In addition, when the boarding and disembarkation detection device 1000 does not detect passenger disembarkation and thus does not receive passenger disembarkation information from the boarding and disembarkation detection device 1000, the MCU 112 counts all passengers who have boarded the current route of the vehicle. It is possible to identify and control the first LED module 132 so that all passenger numbers are visually displayed.

For example, when an error occurs in the system 1, the MCU 112 can control the first LED module 132 to visually display error information (e.g., an error number), and thus, the driver It is possible to directly recognize the state of the system (1).
