Biking nodes. Shaping public space and urban fabrics for cycling infrastructure in European metropolitan landscapes.

European transport sector's 40% of CO2 and around 70% other polluting particle emissions are caused by urban mobility. Due to the climate crisis, cycling is considered as the most sustainable solution in urban fabrics where density and intermodality are the most important factors in territorial development. This research studies the implementation of cycling infrastructure in the metropolitan landscape, regarding both in relation to public space and to urban form. A comparative method is proposed between different European metropolises, considering multiple urban cycling landscapes. Focusing on same-scale urban contexts studied at three scales -regional, metropolitan and urbanin which cycling infrastructure -lanes and segregation, parking and sharing options- interacts with surrounding urban forms -dense and compact, edges and suburban-, the morphology of the territories is studied and mapped from a cycling perspective. The results show the different logics of implementing cycling infrastructure and its impact both on its network behaviour and on its physical definition in public space. In this way, it is possible to describe more precisely the needs of cycling mobility for its correct implementation, as the adaptation of urban morphology to biking does not depend exclusively on factors related to the design of cycling infrastructure. These complementary views seek to shape the constellation of elements that interact between urban cycling and urban form.
