L'intelligence des feux rouges. Sociologie d'une entreprise gestionnaire

One will find here a sociological in depth analysis of a public problem considered as a social form, and more precisely a comprehensive and hermeneutic account of the managing stance in this context. Innovation in road traffic management activities was the empirical field which has been explored. We paid a particular attention to the development of european intelligent transport systems' projects, more precisely in the area of traffic control. We were looking for a theoretical understanding of the interrelations between technical systems, public problems or concerns and actors' intentional stance. We conclude that they are of sociosemantic more than functionnal character.
