Abstract:

In order to construct sustainable road network systems, the three dimensions of sustainability, which are economic efficiency, environmental impact and social equity perspectives, should be significantly and simultaneously taken into account in planning stages. Since these dimensions have trade-off relationships among them, the authors developed a multi-objective optimization model for planning optimal road capacity improvement strategy. The three indicators for measuring each dimension of sustainability were employed as the objectives of the proposed model. The total travel cost which consists of monetized value of travel time and operating cost was adopted as economic indicator. The total emission cost and the GINI coefficient based on the zonal accessibility were adopted as environmental indicator and equity indicator, respectively. An experimental test was performed with the three model scenarios which were investigated to compare the single- and multi-objective approach methods and different objective functions. The Pareto optimal solutions were obtained by using the elitist non-dominated sorting genetic algorithm. The results show that the proposed model, which is based on multi-objective approach and considered all of the three dimensions of sustainability, is more suitable to plan sustainable road network design. In addition, the authors suggested that the frequency rate of a link within Pareto solutions can be utilized for planning priority of capacity improvement strategy for maximizing sustainability on road network.
