Abstract
In this paper, an integrated model for selecting, scheduling, and budgeting urban road construction projects is introduced as a multi-objective time-dependent bi-level network design problem. Three criteria are considered as upper-level objective functions: total travel time, user satisfaction over time, and spatial equity. Two new measures are developed to assess network design scenarios from the perspectives of user satisfaction over time and spatial equity. Given the great complexity of the intended problem, two multi-objective evolutionary approaches (an interactive and a-posteriori) are proposed to solve the model in a reasonable time. These two approaches are novel combinations of different techniques, such as: Genetic Algorithm (GA), Non-dominated Sorting Genetic Algorithm (NSGA-II), Frank-Wolfe algorithm, ordered logit model, and knees identification algorithm. Computational results for various test problems show that proposed approaches have acceptable performance in terms of both solution quality and solution time. To show applicability of the proposed approach in large-sized networks, it is applied to a real case on Isfahan City in Iran.
