| Abstract | The objective of this study was to apply the Road Investment Analysis Model (RIAM) to the Lat Ya - Ban Sai Yok - Sangkhaburi feeder road, part of which has already been constructed in the West Central region of Thailand
in the agricultural valley of the River Khwae Noi. The purposes of the study were to find the most theoretically suitable
maintenance standard, and the most suitable surface type which would minimize the cost of transportation for 20 years into the future and to compare this
with the actual decisions which have been taken. In addition, sensitivity analysis on certain variables such as discount rate, construction option, and traffic growth rate have been performed. Of further interest in this study is the existence of alternative modes of transport parallel to the road. A single track railway from Kanchanaburi, carries significant volumes of goods and passenger traffic. There is a possibility that railway services on this line will shortly be withdrawn.
The impact on road traffic of this possibility was considered.
The results of the analysis for most discount rates show that a high maintenance standard is most suitable for this road link, which serve high traffic volume, and low maintenance standard is suitable for low traffic link. The results also show general agreement with some of the actual decisions which have been taken by the Highway Department. Additional costs
from traffic diverted to the road from the railway line would be insignificant. The main problems faced in using the Model are the effects of congestion and the simulation of scheduled maintenance standard for an unpaved road. |
