EXPO’PED is proposing an original study of the walking mobility of elderly people in a neighbourhood and their exposure to atmospheric pollutants on a micro-local scale. Relying on a multidisciplinary team of geographers, computer scientists and urban environment specialists, the project has developed and combined a smartphone application for monitoring pedestrian routes with sensors for measuring air quality and an in situ audit of walkability and perceptions of air quality, all as part of a participatory approach.

An effective protocole for taking these various measurements have been gradually co-constructed with volunteers during 3 measurement campaigns in the autumn of 2022, winter and spring of 2023.

The data collected is currently being analysed.
