Research Abstract	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.
