Samenvatting
Spatial interaction patterns in an urban region are not an isolated phenomenon per se. Their developments can only be understood as the result of changes in the key components of the urban region. In order to describe, explain, or even predict these developments, a dynamic systems approach focusing on trajectory over time of the urban system is desirable. The main subject of this paper is an overview of dynamic urban models and theories, with a special emphasis on structural changes within an urban system.
