One of the factors in planning forest roads is average skidding distance which is calculated in projects from the map, according to forest road density, however it has a low accuracy. In this study real average skidding distance and theoretical average skidding distance were measured to determine a correction coefficient in Alikia Soltan forest in Hyrcanian forest. In this study real average skidding distance was obtained by putting a meter on the axes of trails. Moreover, theoretical average skidding distance was calculated by means of road density according to the formula. Skid trails were recorded by GPS and overlaid to a topographic map by means of ArcGIS software. Results indicated that for the study area with the average slope of 27% and road density of 10.32 the correction coefficient is 2.1.
