Embodiment

[0034] Such as figure 1 As shown, the method for evaluating the glare impact of the high-speed rail lighting on adjacent parallel expressways in this embodiment, the specific implementation steps are as follows:

[0035] Step 1: Extract the light source characteristics according to the light source parameter data of the headlights and compartment lights of the high-speed train

[0036] Light sources for high-speed trains can be divided into two categories: locomotive lights and car lights. Motorcycle lights mainly include headlights, auxiliary lights, and marker lights. Headlights, also known as headlights, are located at the front of the locomotive. Its shape and function are similar to searchlights, and it has lighting and warning functions. The auxiliary lights are located on both sides above the bumper beam at the front of the locomotive, assisting the headlights for close-up lighting. The marker lights are also located on both sides above the buffer beam at the front o...

Abstract

The invention relates to a method for evaluating the glare influence of lighting of a high-speed rail on a nearby side-by-side expressway. The method includes the following steps that 1, according to light source parameter data of a headlamp light source and a compartment light source of the high-speed rail, light source characteristics of the headlamp light source and the compartment light source are obtained; 2, the most unfavorable position is selected on the expressway; 3, according to the light source characteristics of the headlamp light source and the compartment light source, a headlamp glare evaluation point and a headlamp and compartment light coupled glare evaluation point are selected on a high-speed rail route respectively, and whether or not a high-speed rail train has the glare influence on the expressway under the independent headlamp glare light source condition and the independent headlamp and compartment light coupled glare light source condition is judged; 4, according to the result of the glare influence of the headlamp light and coupling of headlamp and compartment light on the expressway, whether the high-speed rail route causes the glare influence on the nearby side-by-side expressway or not is judged. Compared with the prior art, the method has the advantages of being original, complete, scientific in judgment, extensive in applicability and the like.

Description

technical field [0001] The invention relates to the fields of lighting measurement and expressway safety evaluation, in particular to an evaluation method for the impact of high-speed rail lighting on the glare of adjacent parallel expressways. Background technique [0002] The International Commission on Illumination (CIE) defines glare as: Glare is a visual condition. The formation of this condition is due to improper brightness distribution, or too large a range of brightness changes, or extreme contrast in space and time, which causes discomfort to the observer or reduces the ability to observe important objects, or both. Phenomenon. [0003] The generation of glare will reduce the visual recognition effect of the human eye on the target object and prolong the visual recognition time. Severe cases may even lead to short-term blindness of the light curtain, and have a certain delay after the glare source disappears, which will interfere with the driver's acquisition and...
