The Chemical Reaction Optimization Approach to Solving the Environmentally Sustainable Network Design Problem

Road traffic affects both the environment and the health of the public. Decision makers in the transportation industry are being urged to incorporate environmental costs into road network design. The design of a road network should not only be cost-effective but also environmentally sustainable. A new network design problem (NDP) that takes both vehicle emissions and noise into account is proposed in this article. This proposed environmentally sustainable NDP is formulated as a discrete bilevel program. The lower-level problem is formulated as user-equilibrium assignment. The upper-level problem determines the optimal road capacity expansion to minimize the total costs of emissions, noise, and travel time with the considerations of budgetary and capacity improvement constraints. An enhanced version of a new meta-heuristic named Chemical Reaction Optimization (CRO), and its parameters are solved and tuned by the authors proposed tuning procedure. Two benchmark road networks with different demand levels are used to evaluate the performance of the enhanced CRO and illustrate the properties of the problem. The tradeoffs between emissions, noise, and travel time costs, are also shown. On more than half of the testing scenarios, the authors enhanced CRO outperformed and had a comparable performance with the Genetic Algorithm.
