The Department of Rural Roads, Thailand, is responsible for managing rural roads and their assets to ensure safe and pleasurable conditions for travelers. Annually, the department spends more than 10,000 million Baht for conducting road maintenances. It has been identified that one of the major causes of road damages is a result of the operations of overloaded trucks. This leads to the plan to establish the weigh stations to control and protect the conditions of rural roads across the country.

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 highest net weights are considered feasible for permanent weigh stations establishment.
