“…Therefore, it is necessary to adopt methods such as covering entrance zone sidewall with light coating materials and increasing the lighting intensity of luminaire inside the tunnel to enhance the luminance and luminance uniformity. Other measures would be to install guidance facilities to help drivers adapt to the environment of the tunnel more quickly, and to provide shade and vegetation to reduce the difference in luminance between the inside and outside of the tunnel during the daytime, thus alleviating the psychological load of drivers and improving driving safety (64,65).…”

To quantify and analyze the psychological reactions of drivers at the entrance zone of a road tunnel, drivers’ physiological data (pupil area, saccade range, saccade speed, heart rate, and breathing rate) were collected using the eye-tracking system in a real driving environment. A psychological load model was developed to quantify the multiple psychological indicators and analyze the change of psychological load at different times and locations based on the TOPSIS (technique for order preference by similarity to an ideal solution) improved factor analysis method. Sensitivity analysis was used to explore the effect of psychological indicators on psychological load. Results of tests conducted at different times of day (12:00, 15:00, and 18:00) show that psychological loads increase slowly to 0.52, 0.38, and 0.23, respectively, when outside the tunnel entrance (from −100 m to −50 m), increase dramatically to a maximum value (1, 0.84, and 0.71) when approaching the tunnel entrance (from −50 m to 0 m), and decrease dramatically to 0.61, 0.58, and 0.41 when first entering the tunnel (from 0 m to 50 m), and then decrease slightly to 0.20, 0.13, and 0.12 when driving inside the tunnel (from 50 m to 200 m). The result also shows that the proportions of saccade speed, pupil area, and saccade range are larger than heart rate and breathing rate. Moreover, the psychological loads of drivers are considerably lower at 18:00 than at 15:00 and 12:00, and the psychological loads near the entrance are considerably larger than inside or outside the entrance.

“…Improving the lighting environment by improving light utilization through highly reflective materials has received much attention. − Qin et al found that compared with the fireproof material, the physical properties of the energy storage self-luminous material tunnel (i.e., road surface luminance, sidewall luminance, overall uniformity of luminance, and longitudinal uniformity of luminance) were higher; Chen et al found that the ratio of sidewall to pavement luminance in the tunnel decorated with energy-storage and luminescent coating is 1.3–1.4, which is far greater than the demand of lighting specifications . Some researchers have also developed coatings to modify pavement reflectivity, achieving reflectance rates of up to 60%, to improve the quality of lighting. , However, these materials often have persistence issues and are costly.…”

The quality of lighting in enclosed environments has always been a concern, and in many cases, it even causes a game between comfort (even safety) and energy consumption. How to durably improve the lighting level under the same energy consumption is an important way to solve the problem of lighting quality in closed environments. In this paper, we design a highreflectance composite coating with diffuse reflection and self-cleaning properties (named DRCC). Its reflectance can maintain more than 85% in visible light with heat treatment at 100 °C for 24 h, immersing in pH = 1−13 or 3.5 wt % NaCl solution for 14 days, and even a salt spray test for 14 days. It enables DRCC to maintain a high total illumination (2496 lx) after nine pollution cycles with a retention rate of 93.0%. In contrast, the total illuminance values of the glazed tile and the DRCC primer are only retained to 1510 and 1903 lx, with retention rates of 77.7 and 71.1%, respectively. Moreover, we also inspect the energy consumption under the tunnel environment by DIALux software, revealing that the DRCC will conserve energy by about 14.4% in contrast to the glazed tile. These key properties that have been integrated into the DRCC are expected to provide unique advantages for a wide range of applications in enclosed environments, such as tunnels, basement stores, auditoriums, and so on.
