Generally, the tunnel formed on the road is in an environment independent from the external environment, so it is difficult for the driver and the tunnel manager to judge the environment inside the tunnel.

In spite of the stability rules recommended in this situation, frequent traffic accidents and fire accidents are frequent in the tunnels.

In recent years, along with the development of civil engineering and construction engineering, an alternative to solve the traffic problems in the city center has been proposed. In addition, there are the Daejindo Tunnels which are not affected by the existing ground roads and existing underground facilities, the submarine tunnels connecting the islands and the islands, And the construction of long-length tunnels with large lengths is being actively carried out.

In this way, the existing tunnel environment installed on the road as well as the large-scale tunnel environment independent from the external environment such as the high-speed tunnel, the submarine tunnel, etc., And accessibility is difficult, it is highly likely to be extended to serious catastrophes.

Especially, in case of a fire, even if a quick report is received, it is not easy to access a vehicle such as a fire truck or an ambulance, so that it is a great inconvenience to evolve the fire, and the fire evolves faster than anything.
