Why Snap4City should be adopted and why it can be easy replicated / installed

 

Cities are rapidly transforming their services to address societal, environmental and economic challenges: SDG, DUT, 15MinCityIndex, etc. Verticals are progressively replaced by solutions capable of exploiting a huge range of data channels, exploiting Artificial Intelligence, and cross exploiting data via horizontal data platforms. The lack of uniform design in the vertical creates larger duplications, costs and difficulties in maintenance and scalability. Cities/areas require uniform solutions, independent by sensor providers, exploiting legacy solutions and opening the path to the future and innovation. A Digital Twin, flexible, dynamic and highly interoperable platform leads to increase sustainability and control assets and operational objectives, fully integrated with the territory and stakeholders. Cities need to exploit a plethora of data channels to get and provide hints and controls with respect to the Digital Twins of the single services, building and of the whole city. The first step is the operational control and monitoring, to be organized to use data and models for short and long terms planning.

Snap4City manages multiple domains in the city/area operating system enabling operation, management, plan and strategic views for mobility and transport, energy, environment, government, tourism, security, safety, civil engineering, management for waste collection, lighting, parking, traffic, building, people flow, etc. As it is on more than 45 cities/areas in countries as Italy, Spain, France, Bosnia-Herzegovina, Finland, Belgium, Greece, Croatia, Israel, Sweden, Australia, Brazil, China, Romania, Cyprus, Malta, etc., for data, services or third-party operators.

Snap4City provides real-time and offline solutions to support decision makers in cities to daily operation and plan actions on Digital Twin, grounded on ethical and explainable artificial intelligent, AI/XAI (Artificial Intelligence, eXplainable AI), solutions, deductions and assessments. It provides a complete understanding of the city conditions, producing early warning, providing suggestions, enabling simulations and plans as what-if analysis and optimization. It is used to suggest strategic and real time interventions to improve city services and general quality of life also providing living lab support.

Snap4City is a 100% open-source platform used in many cities and areas, includes Km4City ontological and semantic model (https://www.km4city.org ) to guarantee data interoperability. It is an official FIWARE Platform (https://www.snap4city.org/467 , https://www.fiware.org/ ), compliant with FIWARE Smart Data Models, IoT Data Models, Data Spaces, and a large range of High Level Types, official EOSC (European Open Science Cloud) Platform, official Node-RED Library, official E015 API, etc. Snap4City is provided “as a Service” or installed in your location, cloud, AWS, MS-Azure, etc. (from yourself, as well as by using Snap4City certified company), no licence fee is needed.

Snap4City has also a number of Verticals and Applications ready to use as presented in the following. The platform facilitates a wide range of applications in the smart cities and IoT/WoT (Internet of Things/Web of Thing) integrated domains: defining city strategies, implementing control rooms, realizing ethics and explainable artificial intelligent solutions, computing key performance indicators (SUMI, SUMP, IEEE, EC KPI, etc.), setting up solutions, harmonizing any legacy solution in place.

From security and privacy aspects, Snap4City is GDPR (General Data Protection Regulation of Europe Union) compliant, and passed PENTest. With Snap4City you can create your certified entities/data, and sequences of events using the provided Blockchain support. End-2-end secure connections are established from devices to dashboards, user interface.
