Research on evolution of visual load of mountain highway driving

Due to the complex topography and geological conditions of the mountainous two-lane highway, the road alignment is complex, the excavation is more, the road space is complex and changeable, and traffic safety accidents are frequent. In order to explore the influencing factors that affect the driver's visual load, this paper systematically sorts out the research on the driver's visual load in the field of road traffic safety, and summarizes the concept, influencing factors and evaluation methods of visual load. In future research, it is necessary to consider the influencing factors and changing laws from more angles, and conduct a comprehensive study.
