Multi-objective network design problem considering system time minimization and road safety maximization

摘要

This paper discusses the Network Design Problem (NDP) solved for travel time minimization and road safety maximization. Similarly to other NDP models, the model is formulated as a bi-level multi-objective optimization problem. The estimation of the system time benefit and safety benefit is performed using previously developed methods, and the optimal solutions are found using the multi-objective genetic algorithm. The proposed method is demonstrated on a real-size network, using a large set of candidate projects.
