|Abstract:||This study is concerned with the allocation of the transportation investments and their impact on the regional economy. Because the relationship between regional growth and the transport sector is highly complex, evaluation of alternative transportation plans should be performed with the aid of models which include among the decision variables not only the supply of transport, but also the level of national and regional economy.
An economy-wide multilevel is developed with these characteristics. It is multiregional, multisectoral and dynamic. It consists of three different submodels--multiregional, distribution and network design--connected through an information flow consisting of shadow prices and allocative decisions.
In addition to the allocation of the transportation budget the model estimates the magnitude of regional production, investment and consumption of the non-transportation sectors. Entropy maximizing techniques, resulting into gravity type distribution functions, are employed to determine the magnitude of the interregional flows.
The large size of the model and its nonlinear character--zero-one variables, nonlinear entropy constraints--do not permit the application of direct solution methods. However, the model can be modified, so that decomposition algorithms can be applied. It is shown that the global optimal solution can be obtained by applying in two stages the Bender's Partitioning Algorithm. The computational experience with three test problems points out to a relatively rapid convergence.
To test the applicability of the model to a real world problem the complete model was applied to Greece, a country with acute regional problems. The results of the model show that during the period 1975-1990 the interregional income differentials, as well as the national rate of growth will diminish. Since many of the input data are of questionable quantity additional tests are needed to confirm these trends.
