The invention relates to the technical field of expressway traffic sign evaluation, in particular to an expressway traffic sign layout evaluation method and system, and the method comprises the steps: analyzing the layout requirements of expressway traffic signs, and obtaining different traffic sign evaluation indexes; according to the obtained traffic sign evaluation index, evaluating the actual traffic sign working condition on the expressway to obtain an evaluation value set containing different evaluation values; and processing according to the obtained evaluation value set and the worst evaluation value set of the optimal evaluation value set of the evaluation indexes to obtain the closeness degree of the current highway traffic sign and the optimal evaluation value set, and judging whether the current highway traffic sign layout meets the requirement or not by comparing the set evaluation limit value with the closeness degree. The evaluation mode is simple and efficient, accurate and reliable evaluation can be ensured, and actual evaluation requirements are met.
本发明涉及一种高速公路交通标志评估技术领域,具体涉及一种高速公路交通标志的布设评估方法及系统,通过对高速公路交通标志的布设要求进行分析,得到不同的交通标志评估指标;并根据得到的交通标志评估指标对实际高速公路上的交通标志工况进行评估得到包含不同评估值的评估值集,再根据得到的评估值集与评估指标的最优评估值集合最劣评估值集进行处理得到当前高速公路交通标志与最优评估值集的接近程度,通过设定评估限值与接近程度比较来判断当前高速公路交通标志布设是否满足要求,评估方式简单高效,并且能够保证评估准确可靠,满足实际评估需求。
