Research On The Effect Law Of Driving Psychology Adjusted By Road Tunnel Landscape

A tunnel is not only the bottleneck of highway traffic safety but also the road section with frequent road accidents.Owing to the uniqueness of the tunnel traffic environment,traffic accidents frequently occur.A lot of traffic accidents are attributed to the human factors of drivers.Therefore,the study of the changing process of the driving psychology at the tunnel section and the analysis of the impact of the tunnel environment on driving safety have become key factors to ensure road safety.This thesis takes the impact of tunnel landscape on driving psychology as the most important research content.Based on the uniqueness of the tunnel environment,the thesis studies the law on the impact of the tunnel landscape color and area on drivers’ psychology and proposes tunnel landscape design and layout strategies based on this,thereby proposing great safety theory recommendations for road tunnels.Starting from the analysis of tunnel accidents and the characteristics of tunnel driving,the thesis discusses the causes of road tunnel accidents.Beginning with the study of traffic psychology and visual characteristics,the thesis analyzes the relationship between driving psychology,human eye visual mechanism,and tunnel environment.Based on the physiological and psychological changes and visual efficacy of drivers,the thesis identifies the psychological indicators of drivers as heart rate and reaction time respectively,quantifies spatial enclosure and color values of the tunnel landscape,and establishes a mathematical model of landscape enclosure and landscape color values.Based on indoor simulation experiments and theoretical model analysis,the thesis determines the relationship between the changes of heart rate and reaction time of drivers in the tunnel section and the color values of the tunnel landscape,arriving at the law on the driving psychology at the tunnel section.Through the SD survey method,the thesis investigates the relationship between the tunnel landscape enclosure and the visual comfort of drivers,finally nailing down the specific relationship between the driving psychology at tunnel landscape,characteristics of the tunnel environment,and tunnel landscape colors and establishing a mathematical relational model.Using fuzzy comprehensive evaluation and MATLAB fuzzy logic toolbox,the thesis comprehensively evaluates drivers’ comfort and determines the index weight.By analyzing tunnel landscape cases,the thesis studies the psychological comfort under different landscapes and proposes corresponding suggestions for tunnel landscape layout and design.Finally,the research indicates that the landscape color and enclosure exert a significant impact on the psychological indicators of drivers,and blue and white are preferred for the lighting of tunnel landscape because they can effectively ease drivers’ psychological tension and fidgety feelings.Moreover,when designing a tunnel landscape,the landscape on both sides of the tunnel can be decorated according to the local cultural background,and the green area on both sides of the road can also be expanded.It is also possible to increase the greening construction on both sides of the road,and appropriately add plants and other landscapes to increase the enclosure degree of the tunnel landscape,thereby improving the visual comfort of the driver.The research results can improve the theory of highway safety and security to a certain extent,and have a certain guiding effect on the design of visual landscape of highway tunnels and improve the safety of drivers in traffic.
