However, the emergency equipment provided in the above-mentioned conventional tunnel, however, uses an emergency exit indicator light 4 to indicate the position of the emergency exit provided inside the tunnel, and an emergency exit guide light 5 to the emergency exit. It only performs evacuation guidance that displays the distance of the evacuation. Because of this,
In the event of a fire, for example, if the visibility inside the tunnel becomes poor due to smoke generated by the fire, the emergency exit indicator light 4 and the emergency exit guide light 5 cannot be seen, making it difficult to provide accurate evacuation guidance in such a situation. Can happen.

Further, since the emergency exit guide light 5 merely displays the distance to the emergency exit, there is a problem that it is difficult to determine which side to evacuate to. In other words, in the event of an emergency, the emergency exit guide light 5 is displayed and the evacuation is attempted to the nearest emergency exit, but in some cases, the nearest emergency exit side may be a fire site. There is also a problem that even if you intend to evacuate, you will approach the fire site. On the other hand, although the traveling car could listen to the emergency broadcast on the car radio, it had to eventually evacuate based on its own judgment.
