摘要
在城市道路、桥梁、地铁等大型基础设施施工期间,需建设临时道路保障通行。本文针对临时道路的道路照明需求,提出一种基于信赖域算法的路面亮度数学模型。在对临时道路路面亮度的快速测量的基础上,以信赖域算法将观测数据拟合得到模型参数,并计算路面平均亮度,以判断是否满足规范要求,对于解决城市临时道路路灯快速调整和布置问题具有实际意义。
During the construction of large-scale infrastructure such as urban roads,bridges,and subways,temporary roads need to be constructed to ensure traffic.Aiming at the road lighting requirements of temporary roads,this paper proposes a road brightness mathematical model based on trust region algorithm.Based on the rapid measurement of the brightness of the temporary road surface,the trust region algorithm is used to fit the observation data to obtain the model parameters,and the average brightness of the road surface is calculated to determine whether it meets the requirements of the specification.It is of practical significance to solve the rapid adjustment and layout of urban temporary roads.
