【摘要】:挖掘冬季路面溫度在其他外部變量影響下未來短時間內(nèi)的波動規(guī)律,建立冬季路面溫度短臨預測模型.基于交通氣象監(jiān)測站的冬季歷史監(jiān)測數(shù)據(jù),利用統(tǒng)計學方法確定路面溫度的主要影響因素,應(yīng)用自回歸求和移動平均(ARIMA)模型建模分析,對未來短時間內(nèi)的路面溫度進行預測.結(jié)果表明:允許誤差在±0.5℃和±1.0℃范圍內(nèi),未來3 h的平均預測準確率分別達到81.25%和99.65%,對應(yīng)的平均絕對誤差為0.21℃和0.26℃;允許誤差在±0.5℃范圍內(nèi),未來第1 h的平均預測準確率最高,平均絕對誤差最低,分別達到92.50%和0.15℃.
[Abstract]:The short-term and impending prediction model of winter pavement temperature is established by excavating the fluctuation law of winter pavement temperature under the influence of other external variables in the future. Based on the historical monitoring data of traffic meteorological monitoring station in winter, the main influencing factors of pavement temperature are determined by statistical method, and the road surface temperature in a short period of time in the future is predicted by using autoregressive summation moving average (Arima) model. The results show that in the range of 鹵0.5 鈩,
