Abstract
This book discusses economic effects of transport infrastructure investments at various spatial levels: urban, regional, national and international. The analysis has both a theoretical and an empirical character. The concept of accessibility plays a central role in both the theoretical and empirical part of the book. In the empirical applications both modelling and non-modelling approaches are used. Empirical applications include the impacts of highway and railway construction on urban and regional economies, and the impacts of aviation and high speed rail on international accessibility in city systems.
