Book excerpt: Geographic Information Systems for Intermodal Transportation: Methods, Models, Applications examines the basic concepts and applications of Geographic Information Systems for Transportation. The book discusses the unique characteristics of each transportation mode-- highway, railway, waterway and airway—as well as the combined intermodal transportation network. The book shows how GIS generates vehicle routes and shorted paths, develops transportation demand models, analyzes spatial data, and how three-dimensional modelling is applied to the intermodal transportation. - Includes real-world case studies from diverse situations - Provides step-by-steps insights using data to deliver effective outputs for all stakeholders - Presents models and practices for using GIS techniques to solve intermodal transportation problems - Includes learnings tools such as chapter objectives, discussion questions and a glossary
