Description

Tunnel traffic control system and method

Technical Field

The invention relates to the technical field of tunnel traffic control, in particular to a tunnel traffic control system and a tunnel traffic control method.

Background

Tunnel means a building constructed to pass a road through the inside of a ground or the ground, and is composed of a tunnel body, a tunnel door, etc. Generally, the tunnel type can be divided into mountain tunnels, underwater tunnels and urban tunnels according to the positions of the tunnel type. The most built of the three tunnels are mountain tunnels, and although video monitoring is a mature application, the tunnels are special road sections, and have the characteristics of large digging depth, narrow space environment, large light change, unclear vision and the like, so that the tunnels have larger potential accident risks than the common road sections.

When an accident, a crash and other emergency events occur in the tunnel, secondary accidents, such as continuous collision, fire and other conditions of multiple vehicles, the pressure of traffic guidance and rescue work is extremely high, and the consequences are far more serious than the primary accidents on the common road, because the time for a traffic police or tunnel manager to reach the tunnel site generally needs about 10 minutes, and a large number of vehicles possibly enter the tunnel in the period of time. Vehicles entering a tunnel have two consequences: (1) More casualties can be caused, and vehicles stay at tunnel openings to easily cause vehicle serial rear-end collision due to black hole effect; (2) Because the tunnel belongs to the linear structure, the internal space is narrow, the entrance and exit are only arranged at the two ends, the space for accident handling is very limited, and when a large number of vehicles enter, the limited passage space in the tunnel is occupied, so that rescue force is difficult to reach the accident position, the situation is further enlarged, and larger personnel and property losses are caused.

Therefore, after an emergency occurs in the tunnel, the tunnel traffic is safely and timely controlled, the occurrence probability of accidents and secondary accidents is reduced by an effective means, and the safety coefficient is systematically improved. Accordingly, there is a need for a tunnel traffic control system and method.
