In this research project, we rethink the mobility dynamics in the city context, both from a physical and cognitive perspective, considering a bus line as a starting point to redesign multimodal urban transportation system. We consider a bus line as a complex environment composed of the bus as a public transportation system; the bus stop, where people meet, wait, connect; the city as the urban/architectural/cultural environment; the passengers with their needs; and the information/communication systems and devices. With this perspective, we explore how wireless interactive media technologies can be integrated into every level of a complex bus line, including physical and virtual public spaces and the information/communication system with passengers and urban environment, with the aim of increasing smart mobility and a more efficient information distribution.
