There is a growing interest of flexibility in urban plans, both within the planning profession but also by private investors. The collective idea, both among planners and literature, is that the urban is under a constant transformation. Further, flexibility in planning could be found as key of keeping updated to this constant development. Through the theories of temporary and tactical urbanism the positive and negative aspects of flexibility will be discussed and explored. The combination of literature analysis and interviews has formed the basis for creating an understanding how the practical field and literature interprets flexibility in a transforming era in Sweden. According to literature and interviews, this study has shown that flexibility within the regulations of the detailed development plan is key for cities to adapt to new circumstances.

Bilen är fortfarande ett samhällsproblem som allt fler städer vill komma bort ifrån och istället värna om den mänskliga dimensionen. Gaturummen anses därför vara den plats i staden som ska leda förändringen, ritbordet och kartan är numera negligerade. Denna studie undersöker med hjälp av sex kvalitativa intervjuer Härnösands kommuns arbete med att reducera biltrafiken i gaturummet för att skapa ett gaturum för människor och minskad biltrafik. Resultatet visar att Street Moves är svaret på planeringens svårigheter i de centrala delarna av Härnösands bildominans, gestaltning och acceptans från medborgarna för att få legitimitet i att driva förändring i gaturummet. Slutsatsen är att arbetssättet med Street Moves är gynnsamt och eftersträvansvärt samtidigt som medborgarna som ett verktyg förblir kontradiktoriskt / The car has long been and is still a societal problem that more cities want to get away from and protect the human dimension instead.
