Problems solved by technology

[0002] Highway tunnels are located in areas away from the city center or in mountainous areas with complex terrain. Once an accident occurs, the high temperature and closed environment are not conducive to the diffusion of smoke and flammable gases. The visibility in the tunnel is reduced, and the specific cause of the fire cannot be judged. As a result, the rescue plan was delayed and it was not easy to rescue. On the other hand, the remote location and complex on-site environment hindered the progress of basic rescue. The fire-fighting facilities were not in place, and the traffic paralysis in the tunnel increased the difficulty of rescue.
