Abstract

Abstract: The paper was aimed at analyzing quantitatively drivers' visual illusion in tunnels under different combined visual information conditions. First, a simulation model was built by means of 3Ds Max software, and psychophysical experiments on the speed perception were carried out based on the E-prime software. Then 30 drivers were selected as testees, the speed illusion and reaction time of the testees were measured in different test scenes. Finally, the experiment data were analyzed statistically. The results show that multiscale and multifrequency combined visual information can improve the speed illusion of drivers, and significantly reduce the reaction time, that the multiscale and multifrequency combined visual information has an important influence on the speed overestimation, that under higher luminance level conditions, drivers have a sharper awareness of the speed variation, and that the multiscale and multifrequency combined visual information can increase the effect of visual reference systems, effectively improve the speed perception of drivers in tunnels.
