Since the emergence of urban systems, cities have developed in a mutually inter-dependent process of socio-economic dynamics and transportation linkages. In recent years, Airports worldwide have stepped beyond the stage of being pure infrastructure facilities while the complex dynamics that are taking place at and around international airports represent a crucial element in the post-industrial reorganisation of urban and regional systems. Airports are increasingly recognized as general urban activity centres; that is, key assets for cities and regions as economic generators and catalysts of investment in addition to being critical components of efficient city infrastructure.
