First, the street lamps 10 form a wired communication network through a cable connection, the communication unit 500 is a taxi call server 40 and the street lamp management server via a wired network 20 or a wireless network (30). (50).

Through the network connected as described above, the street light 10 communicates with the street light management server 50 through ubiquitous communication to update operation data, map data, and route information of public transportation.

Meanwhile, a process of searching for and transmitting traffic information through the street light 10 will be described below.

First, the streetlight controller 400 of the streetlight 10 outputs preset public transportation information through the monitor 301 screen of the information input / output unit 300. In this case, the public transportation information outputs a bus list of a route via a road on which the street light 10 is installed.

Next, when the user information input unit 302 of the information input / output unit 300 is selected by a pedestrian operation, the street light controller 400 includes bus line search information, subway line search information, and taxi call search information. The transit search screen is displayed on the monitor 301.

Next, when the pedestrian selects one of the displayed public transportation search screens as inputs, that is, selecting an arrival guidance using a bus or subway as an example, the streetlight controller 400 is connected to the public transportation required to reach the corresponding destination. Route guidance information is output in detail through the monitor 301.

On the other hand, when the pedestrian selects a taxi call among the displayed public transport search screen, the street light controller 400 generates a call signal including its street light identification information, and the wired network 20 or the wireless network 30. Outputs the call signal to the taxi call server 40 to be connected via.

Next, the taxi call server 40 confirms the call position based on the streetlight identification information included in the call signal, and informs the taxi call to the taxi 60 located at the nearest distance.

In this case, the taxi call server 40 may use one of the methods of using map data to which the streetlight identification information is encoded, or recognizing coordinate information included in the streetlight identification information through analysis.

Next, after checking the taxi call, the driver of the taxi 60 is moved to the place where the corresponding street lamp 10 is located to pick up the customer. In this case, a GPS module (not shown) is mounted on the taxi 60, and the GPS module is registered and managed through communication with the taxi call server 40.

On the other hand, the delivery process for the taxi call described as another example as follows.

When the pedestrian selects a taxi call, the streetlight control unit 400 generates a call signal including streetlight identification information, and the taxi signal of the taxi call server 40 in the taxi 60 located around the call signal. Radio broadcast to receive directly wireless without relay.

Next, the taxi 60 confirms the call location based on the streetlight identification information and moves to the place where the passenger is located.

In this case, the streetlight identification information included in the call signal may include coordinate information for identifying a location. When the coordinate information is not included in the streetlight identification information, the taxi 60 determines a call location based on the streetlight identification information. It is assumed that the map data which can be confirmed is mounted.
