Safety Evaluation of a Bridge-Tunnel Connecting Section of Mountainous Highways Based on Drivers’ Heart Rate
With the terrain restrictions, there are quantities of bridge-tunnel connecting sections on mountainous highways, and the traffic accident rate of the bridge-tunnel connecting sections in mountainous highways have always been very high in China. Therefore, the study about safety evaluation of the bridge-tunnel connecting sections of mountainous highways has an important significance for reducing the highway traffic accident rate. Firstly, this study propose a definition about bridge-tunnel connecting sections in mountainous highways. From the aspect of integrated system of bridges and tunnels, this study analyzed the traffic accident characteristics and influencing factors of the bridge-tunnel connecting sections. Based on engineering design data of a typical bridge-tunnel connecting section, a driving simulation test with a model of bridge-tunnel connecting section (“tunnel-bridge-tunnel” type) and simulated foggy weather was carried out using UC-win/Road software. Through the design of appreciate simulation scene and driving simulation experiment, we obtained the drivers’ driving speed and heart rate value under the specific connection bridge-tunnel scene. Then the relationship between the driving speed, foggy weather and the driver's heart rate variability is found. Finally, a safety evaluation index of the bridge-tunnel connecting section design on mountains highway is proposed, which is based on characteristics of drivers’ heart rate.
