Impact of the Surge of Traffic Vehicles on the Traffic Safety of Yangtze River Tunnel

Abstract

According to the uncertain and fuzzy characteristics of the tunnel traffic accident, the fuzzy comprehensive evaluation method based on the fuzzy mathematics is applied to evaluate the traffic safety of the tunnel. Finally, the impact of the surge of traffic vehicles on the safety of tunnel operation can be concluded by comparing the traffic safety evaluation results under the condition of smooth flow and congestion. The results show that the safety level of the tunnel is reduced to a moderate level from a good level. As a result, the risk of traffic accidents increases after the surge of the traffic vehicles in the Nanjing Yangtze River Tunnel. Effective measures should be taken to prevent the occurrence of traffic accidents. The measures of traffic diversion and vehicle classification management can be taken by Tunnel management department to prevent the occurrence of traffic accidents.
