In addition, the bus passenger notification method of the present embodiment is a method of notifying a BMS terminal (hereinafter referred to as a " second bus information terminal ") of a target bus on which a user wishes to board a boarding reservation Can be effectively performed.

The detailed procedure of the bus passenger notification method according to the present embodiment will be described in detail as follows.

First, the mobile terminal 10 can receive a beacon signal at or near a bus stop (S50). Here, the beacon signal may include a beacon identifier as a signal transmitted from the short-range wireless communication apparatus 50, for example, a beacon apparatus installed at or near the bus stop.

The use of the beacon identifier allows the beacon device to be installed at a place or a position of a bus stop adjacent to the beacon device on the basis of a beacon device installed at a predetermined place in at least the BIS server 30 or the mobile terminal 10 associated therewith, (Hereinafter referred to as " second identifier ").

A beacon device is a type of short range data communication device that uses a bluetooth low energy (BLE) and has an operating range of up to several tens of meters. A beacon may include a sound-based low frequency beacon, a light emitting diode (LED), a Wi-Fi beacon, and the like, which are broadly classified according to a method of transmitting a signal in addition to a Bluetooth beacon.

The bus passenger notification method of the present embodiment notifies the bus passenger terminal 20 (hereinafter referred to as "first bus information terminal") of the bus passenger through the short range wireless communication device 50 including the low- (Hereinafter, referred to as a 'first identifier') and related information (first identification information).

Next, in response to information in the beacon signal or the beacon signal, the BIS-related application installed in the mobile terminal 10 can be activated or activated (S51).

Next, the BIS-related application can display the bus information at the bus stop based on the first identification information (S52).

Next, the BIS-related application can sense the passenger's selection input to the bus stop (S53). The selection input includes information about the bus the passenger wishes to board. The mobile terminal 10 may generate bus passenger notification (BPNI) (hereinafter referred to as BPNI 1 or first BPNI) corresponding to the selected input and transmit it to the BIS bus (S54). The first BPNI may include at least one candidate bus information included in the selection input and first identification information. Of course, depending on the implementation, it may include an identifier of the mobile terminal 10 or a passenger identifier.

Next, the BIS server 30 can select the target bus based on the candidate bus information in the first BPNI, bus stop information, and bus operation information (S55). The bus operation information is stored as bus operation information in the second bus information terminals 40 of the buses (including the bus 2) via the bus stop (S41). The bus operation information is periodically or temporarily stored in the second bus information terminal To the BIS server 30 (S42, S43).

Next, the BIS server 30 can transmit bus passenger notification information (hereinafter referred to as BPNI 2 or second BPNI) to the second bus information terminal 40 of the target bus (S56). The second BPNI may be the same or similar to the first BPNI in the containing information dimension, but if the first BPNI includes a plurality of candidate bus numbers, information about one selected target bus among the plurality of candidate bus numbers And may include differences in the inclusion.

Next, in response to the second BPNI, the second bus information terminal 40 of the target bus can activate a bus passenger notifying status (BPNS) indicating that there is a riding reservation passenger at the corresponding bus stop on the bus route (S57). The second bus information terminal 40 may transmit a response signal to the BIS server 30 in response to the second BPNI or in response to activation of the BPNS (S58).

Next, the BIS server 30 can generate target bus information (TBI) (S59). Then, the BIS server 30 can transmit the TBI to the mobile terminal 10 (S60). On the other hand, the TBI generation is not limited to being performed in the BIS server 30, and the TBI can be generated in the second bus information terminal 40 in which the BPNS is activated (see S59a). In this case, the response signal in the step S58 includes the TBI, and the BIS server 30 can transmit the received TBI to the mobile terminal 10. [

Next, the mobile terminal 10 can activate its own bus passenger notification state in response to the target bus information according to activation of the bus passenger notification state on the target bus (S61). Activation of the bus passenger notification state (BPNS) at the mobile terminal 10 may be displayed on the display panel of the mobile terminal 10 or output via the speaker in the form of a completion mark. Further, the BIS server 30 may transmit the target bus information (TBI) to the bus information guidance terminal installed in the bus stop or the first bus information terminal 20 (S62).

The first bus information terminal 20 can activate the bus passenger notification state (BPNS) in the bus information outputted to indicate that there is a scheduled riding passenger at the bus stop (S63). Here, the first bus information terminal 20 can output bus information to the display panel of the first bus information terminal 20 based on bus operation information previously received from the BIS server 30 (S44, S45) .

According to the implementation, the BIS server 30 determines the state of the target bus based on the received bus operation information (S71, S72) (S73), and if another bus in the candidate bus numbers is a bus If it is determined to arrive at the stop first, the target bus can be changed (S74).

Then, the BIS server 30 activates the BPNS of the target bus through interworking with the newly selected target bus (Bus 2) (S76), returns to the previous step S59 (S77), and generates the target bus information (S59). The target bus information is transmitted to the mobile terminal 10 (S60), and the target bus information may be transmitted to the first bus information terminal 20 (S62).
