Abstract
Long-term driving and monotonous internal environment increase the safety hazard of driving in ultralong tunnels. Therefore, methods to alleviate the driving fatigue caused by long-term driving are of great significance to promote the safety of ultralong tunnel driving. Firstly, the environmental factors influencing driving fatigue of ultralong tunnel were analyzed, which can be divided into light environment and interior environment. Then, a driving fatigue detection system based on virtual reality technology was built which can integrate different hardware and software. Finally, based on Laoying ultralong tunnel in Yunnan Province, tunnel models under different environments were established, fatigue relief zone was set up and simulation tests were carried out. The experimental results show that setting a fatigue relief zone in the middle of the long tunnel, in the form of the combination of a “blue sky and white clouds” pattern on the inner wall and a high-color-temperature light source, can make drivers more attentive and effectively alleviate driving fatigue. This paper proposes a virtual simulation technology for fatigue relief zone settings; this technology can be adopted for other similar projects.
