One of the key concepts underlying the science of spatial planning refers to the role of development corridors as a planning instrument to potentially restructure economic space. Although strong evidence exists that corridors are regarded as important spatial development instruments that channel economic development, counter-arguments indicate the need for more diversified strategies at regional and national levels, as well as a greater awareness of agglomeration economies to allow for the integration of corridors as strategic and supporting networks. Drawing on fundamental literature, a regional corridor model was developed with the aim to establish a spatial framework through which corridor development can be integrated as strategic and supporting networks to support the notion of ‘sustainable spatial- and settlement planning’, i.e. the appropriate compilation and administration of policies affecting spatial organisation at local, regional and national levels. Based on the empirical research, regional and national governments could, through the RCM, develop a realistic spatial perspective on long-term settlement patterns and investment opportunities which could transform economic space development and seek to connect the potential of urban systems in economic development.
