Abstract | The Highway Design and Maintenance Standards Model (HDM) was used for economic analysis 'of a low-volume road. The costs considered included total construction costs, road user costs, and road maintenance costs, all described in financial and economic terms. Having predicted the condition of the road, the model estimated maintenance costs and road user costs on a year-by-year basis through the period of use; The purpose of this research was to find the ideal combination of road design and maintenance standards which would result in the minimum total transportation cost at various discount rates for various traffic growth rates, and to examine the performance of the model when applied to the 63 km extension of the Kwai Noi Valley feeder road in west-central Thailand. Three levels of traffic having average growth rates of 7.5, 9.5, and 11.5 percent per annum were tested. Maintenance standards, varying from low to high, ·were tested. The analysis period was 15 years, from 1979 the first year of construction. Five discount rates, ranging from 8 to 25 percent, were used. The results obtained from the model showed that the total transportation cost would be least with a responsive maintenance standard at all levels of traffic growth and discount rates tested. From this study, it was found that .the HDM model is suitable for used in'. Thailand. However, the procedure could be improved by selecting suitable options within the model, and providing more accurate data. |
