摘要
为了探索将数据挖掘技术引入公路交通计量领域的必要性和全面了解标志、标线和突起路标逆反射测量仪的准确性、可靠性以及衰减规律,在分析公路交通逆反射计量技术的发展现状及存在问题的基础上,指出引入数据挖掘的必要性,分析数据挖掘技术在其他领域的应用现状,从数据分析角度探讨了数据挖掘技术在公路交通逆反射计量领域应用的可行性,并进一步总结分析标志、标线和突起路标的计量测试数据结果,并从量化不同因素对逆反射性能的影响、设备寿命预测、设备关键参数优化、计量性能指标优化等方面提出进一步的研究方向。结果表明:标志、标线及突起路标逆反射测量仪的准确性和可靠性随时间呈现衰减趋势,并且二次和三次模型均有较好的拟合效果;标志、标线和突起路标逆反射测量仪的准确性和可靠性在前7年衰减比较缓慢,在第7年之后,其准确性和可靠性衰减加快;根据回归分析结果,预测标志、标线和突起路标逆反射测量仪的寿命分别为13.2、11和11.1年;通过理论、试验分析及简单数学模型拟合分析的传统方法考虑因素少、使用的数据量小、研究结果具有一定的片面性,难以发现大量数据中潜在的知识模式,存在模型预测精度低、量化仪器设备影响因素难、被送检设备时空特征分析难等问题,未来将结合数据挖掘技术,推动公路交通计量领域的发展。
In order to explore the necessity of introducing data mining technology into the field of highway traffic metrology and comprehensively understand the attenuation law of the accuracy and reliability of signs retroreflectometer,markings retroreflectometer,and raised pavement marker retroreflectometer,the current development status and existing problems of highway traffic retroreflective metrology technology were analyzed,and the necessity of introducing data mining was pointed out,the application status of data mining technology in other fields was analyzed.From the perspective of data analysis,the feasibility of the application of data mining technology in the field of highway traffic retroreflection metrology was discussed.The metrology and test data of signs,markings and raised pavement markers were analyzed and the analysis results were summarized,and further research directions were pointed out from quantifying the impact of different factors on retroreflective performance,equipment life prediction,optimization of equipment key parameters,optimization of metrological performance indicators,and so on.The results show that the accuracy and reliability of signs,markings and raised pavement markers show a declining trend over time,the quadratic model and the cubic model have good fitting effects.The accuracy and reliability of signs retroreflectometer,markings retroreflectometer and raised pavement marker retroreflectometer decrease slowly in the first seven years,and decrease rapidly after the seventh year.According to the regression analysis results,the predicted lifespan of signs retroreflectometer,markings retroreflectometer,and raised pavement marker retroreflectometer is 13.2,11and 11.1years,respectively.Through theoretical,experimental analysis and simple mathematical model fitting analysis,few factors are considered and the amount of data used is small.Therefore,the research results are onesidedness and difficult to find potential knowledge patterns in a large amount of data.There are some problems,such as low prediction accuracy of the model,difficult to quantify the influencing factors of instruments and equipment,and difficult to analyze the space-time characteristics of the equipment submitted for inspection.In the future,data mining technology will be combined to promote the development of highway metrology.2tabs,5figs,38refs.
