Application of climate in land transport with an emphasis on interpolation methods

One of the applications of the climate in ground transportation is that we can estimate some of the characteristics of the weather and hydrology of the paths with little or no statistic statistics, since in many cases it is not possible to implement a road project only Due to the lack of long-term climatological data, the reason for using the IDW, SPlINE method, precipitation maps and its consequences in relation to the climatic, hydrological factors mentioned in the road construction projects in the Garmsar axis of Semnan In the longitude "10 51- 25 51 East and geographical area 30-35-35-44-4435 35 is located in the province of Semnan Provider We saw them in Figures 1 and 10 as a result of work, which can be used in ground transportation management.
