This book was released on 2020-08-14 with total page 289 pages. Available in PDF, EPUB and Kindle. Book excerpt: 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.

Available in PDF, EPUB and Kindle. Book excerpt: The selection of highway alternatives is a very complex and challenging problem due to the large number of conflicting factors that must be solved, the great amount and variety of information that must be compiled and processed, and the numerous evaluations that must be performed. Therefore, the motivation of this Master's Thesis research has been to automate the design process and to achieve better results within a shorter timeframe and at a lower cost, to overcome the limitations of the traditional highway alignment alternative evaluation processes and design. For that aim, this thesis presents a highway three-dimensional alignment optimization model that simultaneously develops the optimization of horizontal and vertical alignments along a corridor. It integrates a two-stage heuristic neighbourhood optimization algorithm. The research discusses which are the most important costs and constraints associated with highway alignment optimization, it develops the key steps of the two-stage optimization algorithm and it provides a first degree attempt to develop an optimization model software with Matlab interface that might highly automate the design process in the future. Finally, the model capabilities and applicability are studied applying the optimization model in a real highway construction project case study. Thanks to the application of the model to a real case study, it has been demonstrated that the optimization model provides an effective highway alignment alternative, which satisfies the design constraints and also provides practical information about the optimized alignment. It is also found that the alignment optimized by the model is quite similar to the obtained through conventional manual methods, but the model can greatly reduce the time required (13 hours) for highway planning and design, as well as produce a lower cost solution. Despite the terrain complexity of the study area, the optimized alignment is found without any difficulties. In the studied highway stretch the project alignment total cost (6 226 610 €) is close to the optimized final highway alignment total cost (6 136 872 €), but it definitely contributes to reduce the cost in 89 738 € (-1.4%). As summary of the research, the proposed optimization model can greatly contribute to the productivity of highway engineers, as well as to the quality of the resulting infrastructure. It is concluded that with the implemented heuristic algorithm the optimization model achieves a locally optimal horizontal alignment (inside the corridor) and a vertical alignment that is globally optimal for the very alignment it analysed, meeting the main geometric constraints.

Download or read book Intelligent Road Design written by M. K. Jha and published by Witpress. This book was released on 2006 with total page 456 pages. Available in PDF, EPUB and Kindle. Book excerpt: Traditional textbooks on roadway designs focus on fundamental alignment elements and design criteria. When applying these in practice, engineers must try various design combinations, check whether the resulting alignments satisfy requirements, and evaluate their relative effectiveness. Introducing a systematic and efficient approach to optimize alignments, this essentially practical text emphasizes the use of artificial intelligence (AI) and Geographic Information Systems (GIS) in extensively automated highway design. Based on a series of research projects, it provides a thorough introduction to the mathematical models and solution algorithms for optimizing highway alignments, including horizontal, vertical, and three-dimensional alignments. The text is ideally suited to senior undergraduate or graduate students majoring in civil engineering or transportation management. Practicing highway design and transportation engineers will also find it of interest.

Available in PDF, EPUB and Kindle. Book excerpt: This timely book deals with a current topic, i.e. the applications of metaheuristic algorithms, with a primary focus on optimization problems in civil engineering. The first chapter offers a concise overview of different kinds of metaheuristic algorithms, explaining their advantages in solving complex engineering problems that cannot be effectively tackled by traditional methods, and citing the most important works for further reading. The remaining chapters report on advanced studies on the applications of certain metaheuristic algorithms to specific engineering problems. Genetic algorithm, bat algorithm, cuckoo search, harmony search and simulated annealing are just some of the methods presented and discussed step by step in real-application contexts, in which they are often used in combination with each other. Thanks to its synthetic yet meticulous and practice-oriented approach, the book is a perfect guide for graduate students, researchers and professionals willing to applying metaheuristic algorithms in civil engineering and other related engineering fields, such as mechanical, transport and geotechnical engineering. It is also a valuable aid for both lectures and advanced engineering students.
