Road network analysis for timber transportation from a harvesting site to mills (Case study: Gorgan county - Iran)

Abstract

We summarized the results of the Road Network Analysis (RNA), when the shortest path to reduce travel time in the Gorgan city public road network, in Iran, was evaluated. The main objective was to determine whether by using a GIS-based new route approach it is possible to determine the shortest path from logging site to destination (mills). The results showed that by using the concept of travel time as a measure of the importance of nodes, the shortest path from origin to destination was found. A path with minimum links and lengths as well as maximum vehicle speed is the best. This dramatically reduced the search complexity in terms of routing.
