Keywords: analytic hierarchy process | Department of Rural Roads | Thailand | weigh station establishment

The Department of Rural Roads, Thailand, is responsible for managing rural roads and their assets to ensure safe andpleasurable conditions for travelers. Annually, the department spends more than 10,000 million Baht for conducting roadmaintenances. It has been identified that one of the major causes of road damages is a result of the operations of overloadedtrucks. This leads to the plan to establish the weigh stations to control and protect the conditions of rural roads across thecountry. In order to determine suitable locations for establishing weigh stations, this paper utilizes the analytic hierarchyprocess technique, with two sets of the main criteria under consideration, namely the engineering and economic factors, withtheir six associated attributes. The analysis results suggest the criterion weights of the engineering and economic factors,and their associated attributes, to be used for the calculation of the net weights of the rural roads. The roads with the highestnet weights are considered feasible for permanent weigh stations establishment.
