Problems solved by technology

Due to the particularity of active road tunnels, it is impossible to conduct lighting safety and comfort tests in road tunnels. Now most of the virtual simulation experiments are carried out indoors. The existing road tunnel light environment simulations are mostly static visual simulations. However, for driving For the driver in the tunnel, the tunnel light environment in his field of vision is mostly a dynamic light environment. Therefore, static visual simulation cannot highly restore the actual light environment in the driver's field of vision.

Description

technical field [0001] The invention relates to the field of highway tunnel lighting experiments, in particular to a dynamic simulation experiment method of tunnel light environment based on a driver's field of vision. Background technique [0002] The purpose of road tunnel lighting is to provide drivers with good lighting conditions to ensure driving safety. Due to the semi-enclosed space structure of road tunnels, there is a large gap between light and shade at the entrance and exit of the tunnel. When vehicles pass through the road tunnel, phenomena such as "black holes", "white holes", "adaptation lag" and "visual shock" are likely to occur, resulting in hidden dangers to driving safety. As we all know, for drivers driving in tunnels, the important factors that affect their driving safety are the driver's human eye dynamic visual response and visual adaptability. Therefore, it is important to carry out research on the impact of tunnel lighting on drivers' dynamic vision...
