We will produce three large-scale pan-European smart city service pilots in the eight partner cities. The pilots are in the domains of smart mobility, smart participation and smart tourism. A combination of city organisations' leadership, collaboration between the cities, and a large amount of partners' relevant existing services, interfaces, software, practices and standards in these domains are the key enabler for this broad approach.\n\nFor effectiveness within the project, but even more so for the impact beyond the project pilots, we will package selected prior assets and the project pilot deliverables into a shared, uniform, open source City Service Development Kit – CitySDK. CitySDK is aimed for further developers to use, either in the partner cities or in new cities. With this we wish to enhance the development and innovation capability and between-city transfer possibilities of European Smart City Applications. During the project we will engage a vast number of citizens and developers to further exploit the CitySDK.\n\nAs the pilots are run by the cities and their domains are much in the daily lives of the citizens, the project foresees to reach a total coverage of 31 million people, with up to 0,5 million active real people-users, engage up to 1.000 new developer SMEs in 8 countries, and build a self-sustaining, thriving smart city application ecosystem that lives well beyond the project funding. The consortium aims to contribute substantially to the creation of a single European market for technologically convergent smart city applications, in order to reduce the European internal single market gap against North America and the ubiquitous computing technology gap against some Asian countries.
