Road infrastructure construction costs have spiralled over the past decade and the ability of the road authorities to secure funding for road network expansion has become increasingly difficult. Road authorities either have to prioritise improvement schemes and determine what can be done with the available funds and / or find the means to fund road improvement schemes. The Gauteng Freeway Improvement Project (GFIP) currently being implemented by the South African National Roads Agency Limited (SANRAL) falls into the latter category. Transport models were used extensively for making decisions on what should be constructed and the affordability of the options. This article describes the various transportation / traffic model types and their uses. Some of the more important elements in the development and use of a strategic transport model are explained, with reference to the GFIP work.
