Research Of Traffic Facilities And Landscape Modeling Technology In Expressway Tunnel

By the end of 2016,the total mileage of expressways in China reached 131 thousand km,and 15181 highway tunnels totaled 14039.7km.Among them,there are 815 extra long tunnels,3622.7km,3520 long tunnels,and 6045.5km,which account for 68.86% of the total mileage of the highway tunnels.The throat of the tunnel as the highway traffic has the advantages of improving the line shape,shortening the mileage and protecting the environment.However,the characteristics of the tunnel are easy to cause traffic accidents,such as the long depth,the relatively narrow space and the large difference of light and brightness inside and outside the tunnel,and the traffic accident in the tunnel is difficult to cause the group death group.Injury.According to statistics of highway traffic accidents by domestic scholars,the proportion of tunnel accidents is significantly higher than that of normal roads.In this regard,researchers at home and abroad have studied technologies and methods to improve driver's efficiency and safety.This paper,based on the construction of the tunnel construction project in the Beijing Chongli Winter Olympics in 2022,explores the traffic facilities and landscape to improve the driver's safety in the tunnel.Based on the SCANeRTM studios platform,the simulation driving environment is built,and the driving is collected through the eye movement instrument,the electrocardiograph and the simulated cockpit.In the simulation of driving,eye movement data,ECG data and behavior data were analyzed based on these data.The research of this topic mainly includes the modeling of the elements in the tunnel and the three-dimensional realization,completed the construction of the simulated driving environment.Based on the ACT-R cognitive model,the driver's driving behavior in the tunnel is analyzed and the model is modeled to realize the virtualization of the black and white holes in the tunnel driving process,and the virtual scene data are carried out.Optimization,improve rendering efficiency,control variable method to compare the influence of energy spike,contour mark and reflector on driver.In the process of setting up the tunnel scene,the 3D modeling technology of 3Ds MAX software and the graphics processing engine such as OpenGL are studied.The real time interactive virtual Expressway and tunnel driving environment are realized,and the 3D modeling technology and the human-computer interaction technique are introduced in detail.In the optimization of the simulation driving system,the loading speed of the large virtual reality scene and the computation of the intersection data of the scene are solved by using block loading,geometric cutting,real-time blanking,environmental illumination modeling,hierarchical modeling,and fractal technology.This project is to verify what kind of traffic facilities can better meet the functional requirements of the highway tunnel,driving safety requirements,driving comfort demand,aesthetic demand and the collaborative design of tunnel light environment.The simulation evaluation of driving simulation module,driver's psychology,visual effect,lighting effect and landscape effect are expected to simulate the concept of green highway and have the tunnel engineering of the humanistic system.
