Embodiment Construction
[0043] In order to enable those skilled in the art to better understand the present invention, the technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only the present invention. Some, but not all, embodiments are invented. Based on the embodiments of the invention, all other embodiments obtained by persons of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.
[0044]The test of the present invention is carried out in the middle section of the tunnel. Since the glare threshold value accepted by the human eye under different light environment conditions is fixed, the results can also be applied to the lighting settings of other tunnel sections.

The invention discloses a traffic safety glare measuring and calculating method for tunnel illumination, and relates to tunnel illumination color temperature parameters, tunnel road surface brightness and tunnel illumination lamp rotation angle factors. The traffic safety glare measuring and calculating method adopts vertical illuminance generated by a tunnel light source at a driver's eye position to show the influence degree of tunnel illumination glare on the driver's safety visual cognition to establish driver visual cognition test through implementation of the visual cognition test of the driver in different background light environments, and comprises the steps of: a) setting a tunnel safety visual cognition glare rating scale; b) configuring background light environment parameters; c) setting a visual recognition target object; d) testing the visual recognition of the tested driver; e) resetting another group of different background light environments, and repeating the steps b-d; g) giving a glare threshold; and h) determining a glare detection method in an actual tunnel scene. The traffic safety glare measuring and calculating method provides a glare threshold value of tunnel illumination aiming at different background light, provides a detection method of tunnel glare, and provides a basis for detection and prevention of tunnel glare.
Description
technical field [0001] The invention relates to the technical field of highway tunnel lighting, in particular to a threshold range of traffic safety glare in tunnel lighting and a detection method for traffic safety glare in tunnel lighting. Background technique [0002] Long tunnels, extra-long tunnels and tunnel groups are becoming more and more common. Due to the unreasonable setting of artificial lighting sources in the tunnels, glare often occurs. In the sections where the tunnel route adopts circular curves, complex curves or even spiral expansion lines, the lighting design adopts the same design method for both curved sections and straight sections. The influence of tunnel alignment on tunnel lighting glare is not particularly considered, and the glare situation is particularly serious. pose a risk to the driver's safe driving. At present, there are few studies on glare in tunnels, and the existing studies have problems such as incomplete evaluation factors and diffi...
