Accessibility is a key factor in defining the quality of life and potential for development of both cities and regions. This paper presents an accessibility-maximization approach to inter-urban road network planning. The approach is based on a non-linear combinatorial optimization model. Two heuristics have been developed for solving the model, respectively based on local search and simulated annealing principles. The efficiency of the heuristics was analyzed on a representative sample of test problems involving 10-, 20-, and 40-node networks. In the analysis both solution quality and computing effort were taken into account. The approach was used to analyze the ongoing transformation of the Portuguese main road network. The transformation started in 1985, the year when Portugal joined the European Economic Community.
