Du suivi GPS des individus à une approche chronotopique. Premiers apports d'expérimentations et de recherches territorialisées.

This communication deals with an assessment of the GPS use for analysing complex trips of hypermodern individuals. Based on research conducted since a dozen years in France and Grand Duchy of Luxembourg, it shows the importance of these systems in the analysis of mobility and possible contributions for public transport policies. From a focus on cartographic representations produced as tools for analysis and dialogue with the public and the policy makers, it sets out some pointers for the future.
