In the city of Ghent, a pedestrian mobility application making use of Future Internet technologies (i.e. related to sensor networks), will be piloted on a very large urban scale, i.e. with several millions of users. The BlueMap application enables digital tracking and monitoring of mobile device users in indoor and outdoor environments. The software solution uses unique positioning information (in real-time), based on a digital unique identifier of mobile devices. The software application will be piloted for Smart Cities as event organisers, and event stakeholders & retailers who need accurate presence & tracking information of their consumers or visitors. This solution allows them to make decisions for crowd management and marketing purposes, and increases security handling. The pilot will trial in a Living Lab fashion how BlueMap can become a generic component for Smart Mobility applications in a Future Internet context. The BlueMap application data can live within the Future Internet Smart City Platform that is piloted in the Smart I+P project.
