从公路沿线设施交通安全养护需求出发,建立了公路沿线设施交通安全养护评价指标体系,开发了基于车载视频拍摄的评价指标数据采集系统和指标扣分标准,验证了数据采集的一致性,建立了公路沿线设施交通安全养护评价模型,标定出了模型参数,并选取试验路段利用模型计算值和专家主观打分均值的相关性分析,对建立模型的有效性进行了验证。
Based on the needs of traffic safety and maintenance of facilities along the highway, an evaluation index system for traffic safety and maintenance of the facilities along the highway was established, and a data acquisition system and index deduction criteria based on the vehicle video shooting were developed. The consistency of data acquisition was verified and a The evaluation model of traffic safety and maintenance along the highway is set up, and the model parameters are calibrated. The correlation between the calculated value of the test section and the average value of expert subjective scoring is selected, and the validity of the model is verified.
