The strut 10 is used to mount the monitor 70 and supports the two-hole LED signal lamp 60 together with the horizontal beam 20.

The wind power generator 30 is formed to store electrical energy to the rechargeable battery 51 in the controller 50 when the propeller is rotated by the wind.

The solar cell module 40 stores electrical energy generated by condensing solar energy into the rechargeable battery 51 in the controller 50.

The controller 50 maintains an abnormal signal detection standby state for the rechargeable battery 51. Here, the abnormal signal means a case in which the rechargeable battery 51 is overheated or shorted inside.

In the standby state, when the controller 50 detects an abnormal signal, the controller 50 transmits the abnormality occurrence information to the central server 3 (see FIG. 2) through the communication network (2, FIG. 2), and at the same time, the traffic light is abnormal to the monitor 70. Control to output a signal.

Thereafter, the controller 50 determines whether or not forward event information indicating that an accident has occurred in the forward direction from the central server 3 through the communication network 2.

As a result of the determination, when the forward event occurs and the forward event information is received, the controller 50 controls the monitor 70 to output the contents of the forward event information.
