The applicability of the land surface temperature retrieval products in the road surface temperature monitored for typical highway sections is studied by using the FY-2G and Himawari-8 products. It is suggested that the satellite land surface temperature retrieval products can reflect the diurnal cycle and the daily change of the road surface temperature well, with a good relationship between the two. According to the high correlation between the road surface temperature and the satellite retrieval product, a revised model is established by using the linear regression method. The rolling revised satellite land surface temperature retrieval products give results much closer to the road surface temperature observations than the original results. The absolute deviation in summer is reduced to 2.57℃ from 6.98℃, and the absolute deviation in winter is reduced to 1.62℃ from 3.84℃.
