眩光容易引发交通事故。设置防眩设施的目的，在于降低眩光对驾驶员的不良影响。防眩设施按其效果可分为部分遗光和全部遮光。设计防眩设施应做到既要有效地遮挡眩光又要保证机距，还需照顾到施工、养护、经济、美观等方面的要求。研究成果及实际调查表明，在几种防眩设施中防眩板效果较好，易于施工，费用较低。防眩板设计内容包括遮光角、防眩高度、板宽和板间距。依据科研成果在实用中的验证，一些主要设计参数已经纳入规范。 Glare easily lead to traffic accidents. The purpose of setting the anti-glare facilities is to reduce the adverse effects of glare on the driver. Anti-glare facilities according to their effects can be divided into part of the light and all the light shading. Design anti-glare facilities should be effective not only to cover glare but also to ensure machine distance, but also take care of construction, conservation, economy, beauty and other aspects of the request. The research results and actual investigations show that anti-dazzle plate has better effect in several anti-dazzle facilities, is easy to construct and has lower cost. Anti-glare design includes shading angle, anti-glare height, board width and board spacing. According to the scientific research in the practical verification, some of the major design parameters have been incorporated into the specification.
