Embodiment 1

[0072] Embodiment 1: The present invention is a novel method for constructing plants at the entrance of a tunnel. Its main function is to reduce the brightness difference between the inside and outside of the tunnel, so that the driver can safely and comfortably drive in the tunnel. Establish a correlation model of visual shock affecting parameters through methods such as multiple regression, neural network, gray correlation analysis, etc., seek the main factors affecting visual shock, find the relationship between parameters, and then control the intensity and time of the driver's visual shock. The main research content of the invention. The present invention is described by taking the multiple regression correlation model as an example.

[0073] In the process of driving, there are many factors that will affect the visual concussion response of the driver. The primary factor is the difference between the brightness outside the tunnel and the brightness at the entrance of th...

Abstract

The invention discloses a method for reducing visual oscillation of a tunnel portal and a simulation test platform, and belongs to the technical field of tunnel engineering. The simulation test platform comprises a dynamic cockpit, a curved screen, a parallel light source, a projector, an eye tracker, a spectral radiation brightness meter and a simulation test platform control device. According to the method for reducing the visual oscillation of the tunnel portal,, a regression model of the pupil area change rate, the vehicle speed and the brightness reduction coefficient of a driver is established; a brightness reduction coefficient range meeting the visual comfort of the driver is determined through a threshold value of the pupil area change rate; different vegetation densities and arrangement modes are adjusted through the simulation test platform, a scheme for reducing the brightness difference inside and outside the tunnel within the visual comfort brightness reduction coefficient range of the driver is obtained and evaluated and optimized, and then the vegetation density and arrangement mode meeting the dimming requirement are obtained; by means of the method, the dark adaptation time can be effectively shortened, the visual oscillation is avoided, and therefore the driver can safely and comfortably pass through a tunnel entrance section.

Description

technical field [0001] The invention relates to the field of tunnel engineering, in particular to a method for reducing visual shock at a tunnel door and a simulation test platform. Background technique [0002] A highway tunnel is a special tubular structure with openings at both ends and a closed middle. This structure will lead to traffic with a large difference in brightness inside the tunnel than outside the tunnel during the daytime, and higher brightness inside the tunnel than outside the tunnel at night. Safety issues, and road tunnels have always been the key high-risk road sections during road operation. Improper construction will inevitably lead to huge losses of social life and property, and may even lead to the normal operation of the entire road construction and road network. [0003] Visual shock is an instantaneous blind period that occurs when visual adaptation (light and dark adaptation and other strong visual stimuli) occurs, and it manifests as a short-te...
