The rapid growth of cities raises the challenge of organizing mobility in a smarter and more sustainable manner. City governments face a trade-off between the investment in incremental improvements to the existing infrastructure or developing new technologies towards a smart city. This paper investigates the new urban transportation system for the Tegel area in Berlin. After closure of the TXL airport, the area will be redeveloped into a residential area, innovation hotspot and smart city within Berlin. Also, the current main public transportation line from Tegel airport will be cancelled. This presents the challenge of connecting the area to the rest of Berlin by a new mode of transportation, and organizing mobility within the area. This paper focuses on the different modes of transportation that have been researched. It discusses whether the proposed modes of transportation concern an incremental innovation on the existing transportation network and follows the improvement pathway, or if it creates a shift from transportation to the use of new mobility services and fits onto the so-called shift pathway.
