The Amsterdam Institute for Advanced Metropolitan Solutions (AMS), a collaboration between Delft University of Technology and Wageningen University and the Massachusetts Institute of Technology (MIT), and 6 cities in the Netherlands - Den Haag, Rotterdam, Zoetermeer, Helmond, Zaanstad, Amsterdam - jointly conduct new interdisciplinary research into enhancing the sense of safety in a specific neighbourhood by stimulating social cohesion through the creation of shared rhythms. There are many ways for analysing rhythms. From medical examinations of breath, to identifying the tides in the sea, to analysing rhythms in traffic or electricity use. Rhythm is sensed and analysed in many ways. This research identifies of methods of analyses of rhythms in the physical neighbourhoods and in the large urban datasets that reflect the neighbourhoods. As result a new resource for urban policymaking is proposed .
