To improve drivers′ visual comfort and safety in
tunnels, a set of new pavement luminance coefficient measuring devices are developed.
The reflection characteristics of samples are obtained by measuring the
luminance coefficients of red, yellow, and green pavement samples. Moreover,
virtual experiment method is employed to establish the experimental model and
test video in line with the actual project and analyze the eyemovement characteristics of the subjects, such as the locus of
fixations and pupil change rate, when driving on the three kinds of color
pavement and the original pavement. Results show the following. (1) The reflective
performance of the yellow sample is better than that of the green and red
samples. (2) When driving on the red pavement, the subjects′ viewpoints are the most concentrated, whereas they are the most
dispersed when driving on the yellow pavement. (3) When driving on the red
pavement, the rate of change in the subject′s pupil
area is the largest, followed by that in the yellow pavement. (4) Considering
the reflective performance of the pavement samples, drivers′ visual comfort, driving warning, and other factors, laying yellow
pavements in the middle section of highway tunnels is the most conducive to
drivers′ safety.
