Sidewall Decoration for Highway Tunnels Based on Driving Comfort
(1 School of Highway, Chang'an University, Xi'an 710064; 2. Central & Southern China Municipal Engineering Design and Research Institute Co, Ltd, Wuhan 430010)
Abstract Proper landscape of highway tunnels can effectively alleviate the changes in the driving environment and a driver's discomfort, thus improving the safety and comfort of driving. This paper adopts the method of driving simulation test and uses eye movement and heart rate indexes as the evaluation criteria to evaluate and investigate the comfort and safety of tunnel landscapes from a dynamic perspective. The rationality of this evaluation method is verified through the design of three different landscape models by changing the sidewall decoration inside the tunnels.The results show that the evaluation method of driving simulation test combined with eye movement and heart rate indexes is very applicable to the evaluation of tunnel landscape. The 3 decoration schemes have outstanding effects on driving comfort, but their effect on driving safety is insignificant. All the different schemes would increase the instantaneous load. Specifically, the whitewash scheme has the highest instantaneous load, and the blue sky with clouds scheme has the lowest instantaneous load. None of the 3 schemes would lead to safety issues.
