Therefore, there is a possibility that large human accidents and physical accidents may occur. Therefore, if an emergency such as a fire occurs inside the tunnel, a means of suppressing entry into the tunnel should be provided by informing a follower vehicle traveling toward the tunnel that an emergency such as a fire has occurred in the tunnel.

As a means for blocking the entrance of such a tunnel, there has been conventionally proposed a method of installing an indicator lamp for prohibiting entry on an entranceway of a tunnel, installing a gate-shaped column on an entranceway of a tunnel, To come down.

However, installing only the prohibition lamp on the entrance of the tunnel is not effective in notifying the driver of the following vehicle that a fire has occurred inside the tunnel, and can not accurately notify the situation inside the tunnel, There is a risk that the banner may increase the risk of accidental tangles in the vehicle.

The present inventor has proposed a "tunnel entry blocking device " which prevents entry of a tunnel in the event of a fire or the like through the Korean Patent Application No. 10-2014-0086536.

However, the above-mentioned tunnel entry blocking device is intended to prevent the risk of traffic congestion or chain accident by preventing entry of the tunnel, and it is not intended to solve an accident such as a tunnel fire.
