Introduction: Overpopulation in emergency services is a problem that can be observed worldwide, and although it has been addressed from different disciplines and perspectives, it still afflicts citizens who are subject to long waiting lists before being attended. Objective: The work here describes the design, development and the first validation of a Web and Mobile georeferenced crowd system for the city of Bogotá, Colombia, oriented to inform and empower the citizen on the population status of the emergency services found in the city. Materials and Method: In this document, we present the architecture, design, and features of the GALILEO System, with results regarding the first validation with citizens of Bogotá, to capture the acceptance and perceived impact of this type of solution in the context in which the System is proposed to function. Results and Discussion: Although GALILEO has not yet been massively implemented in the context for which it is proposed, the results presented here allow us to explore how Information and Communication Technologies (ICT) can be proposed to solve complex social problems, particularly considering the role of the citizen as a source and receiver of information.
