THE HIGHWAY COST MODEL EVALUATION OF THE DAR-ES-SALAAM--MOROGORO SECTION OF THE TANZANIA-ZAMBIA HIGHWAY

This report presents an analysis of alternative design and maintenance strategies for the recently completed Dar-es-Salaam--Morogoro section of the Tanzania-Zambia Highway. The anslysis is undertaken using an analytic model--the Highway Cost Model--which estimates construction, maintenance and road user costs as a function of the initial design standards, level of maintenance, and traffic volume and loading. The road, which is showing signs of early failure, is evaluated from two perspectives--a review of the design assumptions which were made piror to constructin; and a review of the alterntives hich are available to the Tanzanian government now that the road has been completed. Specific issues which are addressed include the adequacy of the original design, the possible effects of vehicle overloading, and the effects of applying a low standard of maintenance.
