Applying Visual Analysis Methods for mapping Emotions Felt along Daily Trips

International audienceVisual analytics are tools and methods allowing the visual analysis of large sets of movement data. We here use these methods to analyze intra-urban daily trips of individuals as well as the emotion felt by the individuals along their trip. The interdisciplinary research project ECDESUP (Evaluation, Choice and Decision in the use of Urban and Peri-Urban Spaces, www.ecdesup.org/) allowed us to obtain the data via a survey done in the town of Besançon (Eastern France). The first objective was to determine if some places in the city gather a specific type of emotions (either positive or negative) with respect to the day of the week and/or the time of the day. The second objective was to explain the differences observed: are they explained by the origin or destination place, the goal of the trip, or either the time at which the trip occurred. First results obtained show spatial differentiations in the location of the emotions felt. They also suggest that neither the goal of the trip nor the time of the day can univocally explain those spatial differentiations
