Abstract

A method of dynamically adjusting an emergency coordination simulation system includes performing an emergency coordination simulation for a subarea of a geographic region based on expected user behavior in the subarea and environmental variables of the subarea. An emergency notice is transmitted to a plurality of users. A plurality of citizen sensor reports is received from the users via citizen sensor monitoring devices. The devices communicate with a backend system and form a citizen sensor platform. A consistency check is performed on the plurality of citizen sensor reports. The plurality of citizen sensor reports is filtered to remove outliers. An emergency coordination resimulation is performed for the subarea based on the expected user behavior in the subarea, the environmental variables of the subarea, and the filtered plurality of citizen sensor reports. An updated emergency notice is transmitted to the plurality of users based on the emergency coordination resimulation.
