This contribution aims to explore how ‘atmosphere' can be disseminated in urban settings in Switzerland, through the development of what is referred to as ‘encounter zones` (‘zones de rencontre' in French and ‘Begegnungszonen' in German). This urban planning tool dedicated to regulating traffic and allowing different users (pedestrians, cars, bicycles, etc.) to cohabit in a non-segregated space has been introduced all over the country since its official integration into the national legislation in 2002. The main objective is to determine how these areas can become appropriate settings for the development of a desirable atmosphere, conceived here as a quality of place where social encounters and space sharing can happen. In other words, the purpose is to determine if these areas can become more than just a traffic regulation tool, and contribute to social cohesion and the development of lively neighbourhoods. This paper is based on anthropological empirical findings collected in a larger study on encounter zones in Western Switzerland.
