Experimental method for simulating visual response of driver in road tunnel environment

Abstract

The invention discloses an experimental method for simulating visual response of a driver in a road tunnel environment. The experimental method comprises the steps that a darkroom environment with optical reflecting parameters close to those of an actual road tunnel is constructed at first, an illumination test program is set and runs on a computer, the computer is connected with a projector, a barrier is displayed on a screen in a computer projection mode, and a lamplight controller with the adjustable brightness is installed on the screen; and by matching environment brightness change time with screen display time, a dynamic test of simulating testees to enter the road tunnel at different vehicle speeds is performed, real response time of each testee is obtained by changing graph staying time and calculating recognition rate of multiple images displayed on the screen, a statistic method of extracting multiple samples and a statistic method of performing multiple tests on the same sample are combined according to experiment requirements, and accordingly visual response parameters of the testees are close to visual response parameters of the driver in the actual road tunnel environment under different illumination conditions. By the aid of the experimental method, illumination of the road tunnel can be realized from the viewpoint of safety, and the purposes of guaranteeing safety and saving energy are achieved.

Description

technical field [0001] The invention relates to a research method for the relationship between different lighting conditions and visual reaction time of drivers in the middle vision range of human eyes in a tunnel, and mainly relates to an experimental method for simulating the driver's visual reaction in a road tunnel environment. Background technique [0002] With the implementation of my country's expressway planning network, the number of expressway tunnels is increasing year by year. The effect of tunnel lighting and the relationship between road tunnel operation safety and lighting have become problems that tunnel design, construction and operation units need to analyze and solve. However, there are great potential safety hazards in conducting field research in actual tunnels. Therefore, the simulation method for tunnel lighting operation environment is an important means for us to study tunnel energy saving and safety. Contents of the invention [0003] The object o...
