This paper proposes a multi-objective traffic network design problem considering vehicle gas emission under elastic demand. It aims at improving the efficiency of traffic network and reducing the traffic-related pollution through the reasonable road network planning. A multi-objective bi-level programming model is proposed to describe the traffic network design problem. The upper level attempts to minimize the total travel time, the total construction cost, and the total vehicle emission cost; the lower level is the user equilibrium assignment model under elastic demand. The non-dominated sorting genetic algorithm (NSGA-II) is utilized to compute the upper model. The lower level model is solved by double gradients projection algorithm, which applies the Monte-Carlo simulation method to realize the uncertainty of OD demand. Finally, a numerical example is used to verify the validity of the model and algorithm based on the non-symmetric Nguyen-Dupuis network.
