Something in the air. Municipalities are responsible for making sure there’s clean air on their streets. To do so, air quality is measured at selected locations with the aid of complex and expensive sensors and transmitted to the responsible authorities such as the state, federal government or the EU. If limit values are exceeded, those responsible have to initiate measures to tackle pollution. However, the example of the ban on diesel engines shows that there is no easy or blanket solution for improving air quality. That’s because many factors have to be evaluated and data collected. The questions are very complex and often difficult to answer: Where do the pollutants originate and how do they spread across the city? Who produces the particulate matter and nitrogen oxides and where do they come from?
Intelligent algorithms. Advanced analysis methods based on machine learning are combined with various data sources in the Telekom Data Intelligence Hub (DIH). High-precision, but selective, measurements are interpolated into the entire urban area and extrapolated into the future. On the one hand, this allows a detailed statement about the current situation in the entire city area as well as a forecast of future developments. Information from sensor measuring stations as well as weather and traffic data are included in the calculation of air quality. These are supplemented with open data about building topographies and other traffic information. Thanks to the data network, there’s no need for costly new measuring stations. The DIH also provides support in planning measures to improve air quality – such as controlling traffic management systems so that polluted areas can be bypassed, or the precise deployment of an e-bus fleet to relieve pressure.
Direct data. The DIH provides a comprehensive inventory of air quality as well as forecasts of future developments. Individual points can be specifically observed and evaluated using a tile grid map covering the entire urban area. The value-generating analytics can be developed by impartial data scientists and made available to all users. This neutrality enables the members to provide impartial data. All users have data sovereignty at all times and determine the duration of use and intended use. Telekom guarantees that data will be used for the intended purpose. In addition, customers have the option of simply, transparently and, of course, securely tapping additional sources of income by monetizing their own databases.
