Through the above method, a simulated tunnel is established, and corresponding detection points are set on the maintenance channel and the road surface in the simulated tunnel. Multiple sets of data are obtained through the two points in the simulated tunnel, and then fitted into the corresponding brightness curve. Then, in the actual tunnel to be tested, only the brightness information of the maintenance channel monitoring point needs to be determined and then substituted into the brightness curve to obtain the brightness of the actual road surface of the tunnel to be tested. Then, the concentration and density of solid particles are corrected to effectively ensure the accuracy of the final test results. In addition, the entire process does not require any detection equipment and detection monitoring points to be set on the road surface of the tunnel to be tested, which will not cause any impact on the road traffic flow, and ensure the personal safety of the test personnel. It is also efficient and accurate. Among them, the brightness of the maintenance channel detection point in the tunnel to be tested is obtained by an existing imaging brightness meter.

[0049] Determine the actual illuminance Lux of the lamps in the tunnel to be tested act :

[0050] Lux act =Lux or ·LSD·LLD·RSDD·LAT·δ;

[0051] Where: Lux or is the initial illumination of the lamp, δ is the comprehensive attenuation coefficient caused by other factors;

[0052] Control the lamps in the simulated tunnel according to the actual illuminance Lux act Through the above, the lighting state of the lamps in the simulated tunnel can be basically consistent with the lighting state in the tunnel to be tested, thereby ensuring the accuracy of the final test results.

[0053] In this embodiment, the real-time concentration and density of solid particles in the air in the tunnel to be tested are obtained, and the actual road surface brightness is The correction to obtain the final brightness specifically includes:

Through the above method, the influence of solid particle concentration and density in the air on tunnel lighting is taken into account, so that the final evaluation result can be accurately determined, thereby avoiding the concentration and density of air particles in the simulated tunnel being lower than the concentration of solid particles in the actual tunnel to be tested. If it is directly calculated and determined, the brightness value in the tunnel to be tested is lower than the actual value, resulting in a large error in the result.

[0060] The concentration and density of solid particles in the tunnel to be tested are measured by using an existing particle concentration sensor and a particle density sensor.
