This paper presents a maximum-accessibility optimisation approach to programming road network improvements. The approach is based on a non-linear combinatorial optimisation 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 analysed 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.
