A road network design model considering horizontal and vertical equity: Evidences from an empirical study

The considered equity goals are represented by a proper outcome indicator, specified for uncertain and/or approximate variables. The consequent NDP model is then a multi-objective fuzzy programming model that allow determining the most equitable solution aiming at reducing the realization costs according to a set of constraints. An application of the proposed method is given to solve the equity network design optimization and the results are discussed.
