Abstract
Because the disaster prevention and control plan of highway adjoining tunnel and tunnel group is quite different from an individual tunnel, how to define an individual tunnel, adjoining tunnel, and tunnel group plays a crucial role in deciding the tunnel disaster prevention and control plan. Once the accident happens in a tunnel, especially in fire, the traffic must be controlled. Meanwhile, how to adjust the accidental tunnel and non-accidental tunnel accordingly is also the key problem that should be studied in intelligent traffic safety. Here, by the way of setting tunnel units, the definitions and parameters of highway individual tunnel, adjoining tunnel and tunnel group have been worked out. Besides, considering that the disaster prevention and control of adjoining tunnel and tunnel group in accidents is more complicated than that of individual tunnel, and that tunnels affect each other, based on the intelligent linkage control technology, the traffic control of many tunnels on the same line while in fire has been researched carefully. To some extent, the research result will prevent the traffic accident from becoming worse and the secondary disasters from happening, which is of great significance to the conduct of research on intelligent traffic safety of highway adjoining tunnel and tunnel group in accidents.
