Road transport investment model RTIM3.
To simplify the economic appraisal of road investments in developing countries, a new version of the Road Transport Investment Model (RTIM) has been issued by the Overseas Centre of the Transport Research Laboratory. The model consists of a series of linked compiled spreadsheets that take the user through the stages of an economic appraisal. It is easy to use and offers context-sensitive help facilities, data checking on input, and tabular and graphical outputs. The model runs quickly and easily on a small personal
computer. Two examples of its use in Tanzania are described.
