If we do not anticipate for a transport revolution within 10 years, we are forced back to autarkic ways of life. Transport and our built environment are greatly interrelated. What if we could look at transport from the point of urban development? Is it possible to assess why a mode of transport is right for a city based on an urban impact we wish to establish? These questions rely on understanding transport, demographic change and government policies. The challenge faced is how the energy transition in mobility can serve policy initiatives addressing the decline of population. This thesis is structured in five main chapters: (1) Introduction, referring to aim, scope and methodology; (2) literature review regarding transport revolutions, conditions, effects and future predictions; (3) demographics, trends in the Netherlands, parkstad and related policies; (4) choices in urban development & transport; (5) conclusions and recap findings. This research states the importance of rethinking mobility towards demographic trends.
