Log-traffic forecasting is important in determining road standards. According to a previous article, a circular road can be cut at the equilibrium point of the log-trucking cost of going and returning from the entrance, and an even more complicated circular-road network also can be formed into a tree-shape by the following steps. Step 1 : a road which flows into a circuit can be ignored in order to cut the circuit. Step 2 : circuits are cut one by one from the nearest and shortest one from the main road and entrance to the planning area. Now a supplementary rule for Step 2 is necessary if an interior connection-road is longer than the outer road, that is, the interior connection-road must be considered as an outer circuit. Indeed, interior long connection-roads have original functions of yarding and hauling. but it is desirable to make a new connection-road to have more efficient hauling roads. This supplementary rule can be used not only to forecast log-traffic but also to estimate the location of circular road-networks.
