ABSTRACT
In this paper, the dynamic definition of the tunnel group is used to determine the critical value according to the tunnel group and to determine whether the tunnel group is based on the distance S. Taking the Luan Chuan Highway in Luoyang City as an example, the driving safety characteristics of the highway tunnel group was systematically studied and analyzed. In order to improve the construction and operation of tunnel group, the tunnel group accident risk evaluation model is established and different sections of
1 INTRODUCTION
In view of the current serious situation of traffic accidents, this paper evaluates the risk of traffic accidents using the fuzzy comprehensive evaluation method. There are very few research works focusing on the tunnel group. Current references mainly focused on the definition of the tunnel group, the safety evaluation system of tunnel group, the influence factors of the safety of the tunnel group, and the practical safety technology of the tunnel group. However, the definition of the tunnel group and the operation environment of the identification are still not clear. Although the definition of the highway tunnel group is different, it can be mainly divided into two types: static definition and dynamic definition. The static definition of the highway tunnel group is used in the existing traffic environment, given the concept covers tunnel extension attributes, such as the limited value of the fixed distance between two tunnels. The value generally consists of various factors affecting the maximum distance. The dynamic definition of the highway tunnel group is set according to the tunnel design vehicle speed, traffic volume, and variable factors.
