Development of wide area road surface temperature forecasting model for urban area

本文提出的广域路面温度预测模型，可以利用DSM和热平衡方法预测沿着道路的路面温度，整个路线上的路面温度平均绝对误差为1.5 ℃，该模型可以利用空间分辨率大于10 m的DSM精确地计算路面温度。在不使用该算法的情况下，使用联合收割机组合山元素和从计算例程中去除不可见山元素的算法减少了CPU时间。

Wide area road surface temperature forecasting model was proposed in this study allows to forecast the road surface temperature along a road network using the DSM and heat balance method.The mean absolute error of road surface temperature over the entire route was 1.5 degree celcius.This model can calculate road surface temperature accurately with DSM which spatial resolution is greater than 10m. CPU time with an algorithm to combine mountain elements and to remove invisible mountain elements from calculation routine was reduced without the algorithm.
