基于MATLAB建模的路侧交通标志安装角度量化研究
Quantitative Study on the Installation Angle of Roadside Traffic Signs Based on MATLAB Modeling
摘要: 由GB5768规范给出道路交通标志水平安装角度范围在0˚~10˚或30˚~45˚,但规范中并未给出具体场景下的取值方法,导致实际安装中易因角度不当产生眩光,存在安全隐患。本文基于光学反射原理与三维空间几何关系,构建路侧交通标志安装角度优化模型,以太阳矢量、标志法向矢量、观察者视线矢量为核心参数,通过MATLAB建立数学模型,综合分析了纬度以及道路走向两种因素,最终得出了不同纬度和道路走向下的最佳安装角度,为路侧交通标志的科学安装提供了量化参数。
Abstract: The GB5768 standard specifies that the horizontal installation angle of road traffic signs should be in the range of 0˚~10˚ or 30˚~45˚, but it does not provide a method for determining the angle for specific scenarios. This can lead to glare due to improper angles during actual installation, posing safety risks. Based on the principles of optical reflection and three-dimensional spatial geometry, this paper constructs an optimization model for the installation angle of roadside traffic signs. Using the sun vector, sign normal vector, and observer line-of-sight vector as core parameters, a mathematical model is established in MATLAB. The study comprehensively analyzes the effects of latitude and road orientation, ultimately determining the optimal installation angles for different latitudes and road directions, providing quantitative parameters for the scientific installation of roadside traffic signs.
