The document describes a Mobile Information and Citizen-Sensing (MICS) subsystem that allows for two-way information exchange between citizens and their municipality. MICS enables citizens to report incidents and issues via a mobile app, and receive emergency or event notifications from the city. It processes geo-located reports and broadcasts using geo-fencing to only send relevant information. In the ACCUS project, MICS will connect to an Integration and Coordination Platform to automatically share data with other urban systems and provide cross-domain applications. MICS is intended to improve safety, increase civic engagement, and help municipal services by utilizing citizen-reported information.
