For urban planning and design one of the main challenges is to understand how urban form impacts urban life where the people co-presence in public space (i.e. walking, sitting, standing) is one of the most important factors. How many people that share public space is known to affect many socio-economic processes in cities such as segregation (i.e. who meets whom) and local commercial markets (where economic activities can flourish and where not). Sweden is in the middle of an exceptional attempt to build 700.000 housing units until 2025, which has the potential to redirect Swedish cities into more sustainable trajectories where knowledge how the built environment affects movement flows is key.
