Referring to FIG. 1, the bus riding information providing system according to an exemplary embodiment of the present invention includes a vehicle terminal 100, a wireless repeater 200, a central control server 300, and a bus stop terminal 400.

The vehicle terminal 100 transmits the bus internal information, which is provided in the bus and grasped in real time, to the wireless repeater 200 through a wireless communication means. Here, the bus internal information includes remaining seat information of the corresponding bus and image information photographed inside the bus.

The wireless repeater 200 transmits the bus internal information received from the vehicle terminal 100 to the central control server 300, and transfers the boarding information received from the central control server 300 to the bus stop terminal 400.

The central control server 300 is a system for centrally managing the overall information according to the operation of the buses running for each route. In particular, the central control server 300 according to an embodiment of the present invention receives the bus internal information from the vehicle terminal 100 of the bus in real time or for each designated time, and adds the bus internal information, the number of stops and the time required for the bus arrival. The bus boarding information is generated and provided to the bus station terminal 400 where the bus is expected to arrive.

Here, the number of stops is the number of stops existing on the line of the bus, from the position of the bus to a predetermined bus stop where the user waits.

Here, the bus arrival time may be a time required for the bus to arrive at a predetermined bus stop where the user waits. For example, the bus arrival time may be displayed as a scheduled arrival time in FIG. 5.

The bus stop terminal 400 is fixedly installed at the bus stop and receives bus ride information on at least one bus arriving for each route from the central control server 300, and receives one or more of the information included in the bus ride information accordingly. Display it for the user to refer to when riding the bus.

Meanwhile, the detailed configuration of the bus ride information providing system according to an embodiment of the present invention will be described in detail with reference to FIGS. 2 to 4.
