Citizen Sensing

A data collection approach in which members of the public use mobile devices or other tools to gather and report information about their environment, contributing to collective datasets that can inform decision-making. In accessibility contexts, citizen sensing enables people to report physical accessibility barriers such as broken sidewalks, missing curb cuts, or inaccessible building entrances through mobile apps, creating crowdsourced accessibility maps that help both users plan accessible routes and city administrators prioritise infrastructure improvements.
