| Abstract | The purpose of this research was to study the performance of
the Road Transport Investment Model (RTIM) when applied to a feeder road in a rugged area, the effects of choice between a gravel or bituminous pavement, the benefits of adopting different stage "construction alternatives, and study of the consequences ·of uncertainties in traffic fore
casts. The model was developed by the British Transport and Road Research Laboratory to study the design and operation of new or existing roads in
developing countries. A case study of the application of the model to a road section 10 km
in length, a portion of the Sai Yok-Thong Pha Phum-Kao Laem Dam Feeder Road which is situated in the western part ·of Thailand, was carried out.
This feeder road was designed by consultants .as a gravel road but is being built as a paved road with double bituminous surface treatment by the Thai Highway Department. Traffic forecasting was carried out, mostly based on the vehicle growth approach. Discussions of details have been made for construction costs, vehicle operating costs and maintenance costs as predicted by the standard model and a modified model. It was found that there was not sufficient reason to apply this model to estimate the construction cost ·of a road in a rugged area. Road user costs predicted by the standard model, and with speeds modified to reasonable levels, were not significantly' different. The maintenance
costs of paved roads were found to be too low, compared to those given by Thai Highway Department and consulting engineers. It was found that an
asphaltic-concrete surface would be the best choice of pavement. The Thai Highway Department is justified in its decision to construct this I feeder road as a paved road with double bituminous surface treatment. The benefits from adopting stage construction strategies were found to be
not significant.
In the present study of a feeder road, it was found that the vehicle operating cost over a 15-year period of service would be about 73 to 81 percent, the value of users' time about 2 to 4 percent, amortization of
construction cost about 14 to 23 percent, and road maintenance less than 1 percent of the total cost of transportation, depending on the pavement
type selected. |
