Concept General idea of the project

cf. city flows is a visualization of urban bike mobility.

cf. city flows is a visualization of urban bike mobility designed to help citizens analyze bike-sharing system.

cf. city flows is a visualization of urban bike mobility designed to help citizens casually analyze bike-sharing systems in the context of a public exhibition space.

cf. city flows is a visualization environment of urban bike mobility designed to help citizens casually analyze bike-sharing systems in the context of a public exhibition space. Large screens show the space of flows in bike sharing.

cf. city flows is a comparative visualization environment of urban bike mobility designed to help citizens casually analyze three bike-sharing systems in the context of a public exhibition space. Multiple large screens show the space of flows in bike sharing for three selected cities: New York, Berlin, and London.

Bike journeys are represented in three geospatial visualizations designed to be progressively more analytical, from animated trails to small-multiple glyphs.
