Level-fuzzy comprehensive evaluation method of urban tunnel traffic safety

With the continuous increase of the road mileage of Nanjing City, the traffic safety state, traffic operation status is getting more and more attention. The traffic safety state of urban road tunnel is scientifically evaluated, and the research on the relevant aspects is not very mature in China, but its importance is obvious. This study aims to establish a set of scientific evaluation system based on the tunnel traffic safety analysis according to the main factors affecting the traffic safety, in order to construct an evaluation system and relevant evaluation method specialized for urban road tunnel traffic safety to provide theoretical basis to improve the safety of tunnel traffic.
