Basic Urban Dynamics
Urban dynamics try to evaluate the main components initiating or being affected by changes in an urban area. Among the numerous factors impacting urban dynamics, transportation is of high significance. It is often expected that investments in transportation will have positive economic consequences that may involve a feedback mechanism resulting in additional future transport investments. Transport investments are expected to improve the accessibility of passengers and freight, which in turn will improve the overall performance of a regional economy. Even if strong associations can be identified between transport improvements and economic (and spatial) changes, stating causality is conceptually inaccurate. New terminals, modes and infrastructures do not necessarily result in economic growth, clustering, productivity gains, employment and additional investments in related sectors. For this reason alone, understanding urban dynamics remains a complex and uncertain task.
