Optimization Design of Shading Shed Transmittance in Highway Tunnel Entrance

Abstract:

Shading shed transmittance of highway tunnel entrance should be designed to be compatible with the driver visual characteristics. By using qualitative and quantitative analysis methods, change law between pupil area and illumination was found through driver visual characteristics experiments in tunnel entrance. Optimal design algorithm of shading shed transmittance in highway tunnel entrance was established. Nanwutai tunnel on Baotou to Maoming highway are selected as research case to prove the model. The results of this study provide evidence that the model has obvious superiority.
