Sommario/riassunto

This book deals with alignment optimization models for planning rail transit. After a general introduction to the basics of alignment optimization theory, it presents different alignment optimization methods to deal with different situations. It shows how to set up a 3D GIS scene for alignment interaction design, including location calculation of an alignment, alignment expression in a 3D scene, and the spacial relations between geographic objects, horizontal alignment, and vertical alignment. Further, it presents methods for solving more



complex alignment optimization models, and shows for each different rail transit situation, how to calculate investment, energy consumption, and environmental influence. All in all, this book offers an interesting and timely reading to both researchers and professionals in the field of optimization theory, transportation planning, and GIS.

Sommario/riassunto

"Translated from the original French, valuable monograph examines processes of migration in the Cañete valley, exploring history of migratory movements, and the nature of rural exodus and its impact on community structures. Concludes with a demographic study of return migrants"--Handbook of Latin American Studies, v. 57.
