Artificial intelligence in highway location and alignment optimization : applications of genetic algorithms in searching evaluating and optimizing highway location and alignments This monograph provides a comprehensive overview of methods for searching evaluating and optimizing highway location and alignments using genetic algorithms (GAs) a powerful Artificial Intelligence (AI) technique. It presents a two level programming structure to deal with the effects of varying highway location on traffic level changes in surrounding road networks within the highway location search and alignment optimization process. In addition the proposed method evaluates environmental impacts as well as all relevant highway costs associated with its construction operation and maintenance. The monograph first covers various search methods relevant cost functions constraints computational efficiency and solution quality issues arising from optimizing the highway alignment optimization (HAO) problem. It then focuses on applications of a special purpose GA in the HAO problem where numerous highway alignments are generated and evaluated and finally the best ones are selected based on costs traffic impacts safety energy and environmental considerations. A review of other promising optimization methods for the HAO problem is also provided in this monograph Publishers website About the authors Overview of highway location and alignment optimization problem.
