Sudan transport study model (Inglês)

This is the seventh in the series of Transport Planning Models Study papers. The Lockheed model places transportation sector and project planning in a general planning framework which facilitates comparison between transport and nontransport projects. Transport projects and projects in other sectors are ranked heuristically according to multiple objectives and criteria, political and social and well as economic. A regional economic model is used to generate surplus and deficit zones for each major transport commodity, and three transport submodels are used to determine: (1) the costs and performance on each link; (2) the optimum route for each origin-destination flow; and (3) the optimum interzonal distribution of traffic flows. The implementation timing of potential transport projects may be tentatively determined by a mixed linear and integer programming routine in the route optimization model, but the implementation ultimately recommended by the model depends on the project's rank vis-a-vis projects in other sectors and on available funds. Congestion costs are not considered in the model, but there is a fixed capacity constraint for each segment of the transport network in the route assignment model.
