Challenge / Goal
To save energy, reduce CO2 emissions and facilitate a cleaner, cleverer flow of traffic and many other challenges, for a smart city the use of digital technologies is essential for up-to-date information, communication, data exchange, planning, analysis and connectivity. The City of Munich, in the context of the Smarter Together project, has built a “Smart Data Platform” to collect and handle all generated smart city data accordingly.
In parallel to setting up the Smart Data platform, a blueprint was developed which describes all elements that should be taken into consideration by a city, when starting to collect and generate “Smart City Data”. All elements that are important for a city – including data privacy aspects, data classification and anonymization, use case building and a possible data model – are discussed in the “Data Gatekeeper” concept.
The “Smart Data Platform” offers several interfaces to enter the data from different use case scenarios of the project Smarter Together (e.g. energy, sensors and mobility stations). Data formats and protocols are all based on open standards. The platform allows analyzing the available data and provides the results into an analysis dashboard. Selected results are accessible for a broader public via the Munich SmartCity app. Depending on the use case, the platform’s analysis engine can combine several data sources and merge the information to show dependencies and patterns between the different sources of information.
The City of Munich, a trusted authority for the administration of data, has committed itself to involving all relevant stakeholders and defining suitable conventions and rules in the context of possible fiduciary and business models relating to the use and provisioning of data. This information and these transparency rules were described and discussed in a “Data Gatekeeper” concept (which can be made available for cities interested in developing smart city data concepts). This paper contains extensive recommendations, “golden rules” and guidelines on trustworthy dealings with data in the context of smart cities. Aspects of importance to all urban stakeholders – from a discussion of relevant paragraphs of the new European General Data Protection Regulation (GDPR) to specific recommendations for technical implementation of rules in the context of data platforms – are sketched in the document.
Finally a “Transparency Dashboard” was designed to describe all sensors, data analysis mechanisms, and data handling aspects of the project in a most transparent way. The Transparency Dashboard is a website, where Citizens and other interested people get a good overview about which data is generated, how it is transferred and for which purposes it is analyzed within the Smarter Together project.
