The aim of this paper is an estimation of the waste heat distribution based on land use and waste heat in urbanized area. The waste heat distribution is estimated in 2 cases (the present and the future) in Kisarazu and Kimitsu cities in Chiba prebecture in whitch Tokyo Bay Road will be construited in future. The waste heat distribution is shown on land use map by a mesh analysis. The mesh size is decided by calculating the area of influence which the change of a difference in temparature keeps constant. The waste heat is estimated by some source unit in the area. An allocation procedure of land use is led by the rearengement of the waste heat distribution.
