Project coordination

Mobiliscope
Cities around the clock

Mobiliscope is a free and open-source web mapping platform for the interactive exploration of cities around the clock. Using large origin-destination surveys, the Mobiliscope displays maps and segregation indices in 55 city regions (59 in France and 6 in Canada) over the 24h a day.

RelatHealth
A relational approach to place effects on health in urban areas

In Paris (France) and Montreal (Canada), we adopt a relational approach to place effects considering people’ place experiences though regular activity locations and perceived neighborhoods. The project aims at exploring the spatial mechanisms involved in social inequalities in health through the following question: how people’s place experiences shape social inequalities in accessibility, and ultimately neighbourhood effects on health?
