Fraunhofer IAO and Telefónica Deutschland are investigating how cell phone data could benefit traffic planning
Researchers at Fraunhofer IAO are carrying out a study to determine whether data from cell phone networks could offer a reliable source of information for traffic planning and an improvement over current data collection methods. Telefónica Deutschland is supporting the research project by providing anonymized cell phone data.
Stuttgart is facing major challenges in regard to mobility and traffic. The city is struggling with congestion, excessive noise and stress, and there is a clear need to improve air quality. This deteriorating situation has prompted the state capital of Baden-Württemberg –and a growing number of other cities – to seek out new ways of optimizing transport planning and mobility management.
Access to accurate transport data is one of the key prerequisites for taking concrete action. Collecting this data is a time-consuming business, however, and the results of these measurements frequently fail to reflect the huge variations in real-life situations.
Creating anonymized mobility profiles using cell phone data
This is where the intelligent analysis of cell phone data can make a big difference. This data is collected automatically during the normal course of business at Telefónica Deutschland – for example when a cell phone communicates with a cell tower to make a call or surf the Web – and it can be used to create anonymous mobility profiles.
Using cell phone data for transport planning and design would be an economical option that would offer round-the-clock availability and relatively easy access to broad samples. What’s more, the data could give cities the opportunity to tailor specific infrastructure projects more closely to people’s real needs by providing more accurate information on when and where people travel.
Fraunhofer IAO study to stretch over several months
As part of a three-and-a-half month research project, Fraunhofer IAO is conducting a study to investigate whether mobility data is suitable for measuring traffic flows in cities and whether it is superior to other methods of collecting data. The first step is for the researchers to analyze the status quo of traffic measurement methods based on case studies and interviews with experts.
The next step for the research team will be to shift their emphasis to Stuttgart by comparing the data from existing traffic surveys conducted in the region with the insights obtained from the city’s cell phone data. One of the key things the researchers will be focusing on is the real-life variation caused by factors such as heavy rain or major events being held in the region. The hope is that this study will reveal how much potential this data source offers in comparison to other data collection methods.
Telefónica Deutschland is the research partner who will be providing the required cell phone data. This data is anonymized in a three-step process certified by TÜV Saarland, which ensures that customers’ personal data is fully protected. This process makes it impossible to link the data to individual customers. Markus Haas, Chief Operating Officer of Telefónica Deutschland, hopes that the study will provide impetus for further projects in the field of advanced data analytics: “As a network operator, our core business yields huge quantities of data. We’re pleased that such a prestigious institute is investigating whether we could contribute toward improving transport planning by analyzing this data.”
Stuttgart – the perfect test city
Back in 2013, Stuttgart’s mayor Fritz Kuhn led an initiative which saw the state capital develop a new sustainable mobility action plan known as “Nachhaltig mobil in Stuttgart.” The plan included details of the key measures to be taken by the local authorities in nine fields of action. This is exactly the kind of scenario where the Fraunhofer IAO study can provide vital information in regard to issues such as upcoming roadworks and the availability of public transport.
Dr. Michael Münter, who heads up the strategic planning and sustainable mobility department at Stuttgart city council, explains why the study is important: “Many people understandably wish to have as much individual mobility as possible. We need to achieve an acceptable balance between people’s individual mobility needs, environmental concerns, and the interests of the city and the people who live here. Our action plan to promote sustainable mobility in Stuttgart aims to highlight innovative urban mobility projects that have a promising future. That’s why we’re looking forward to getting the results from Fraunhofer IAO on how we can use cell phone data for transport planning and design in Stuttgart.”
The potential of data analytics for traffic and the environment
Telefónica Deutschland hopes that the results of the study will provide it with further valuable insights for its work in the field of advanced data analytics. The telecommunications company is already running a pilot project in Nuremberg to investigate the extent to which air pollution can be calculated on the basis of cell phone data. The results of Fraunhofer IAO’s project will provide further insights into the potential benefits of data analytics for transport and the environment.
Prof. Anette Weisbecker, deputy director of Fraunhofer IAO, explains how the study will help: “It’s a complex business getting precise measurements of traffic flows in cities. Our study will reveal the extent to which transport planners could use mobile phone data to achieve more accurate, efficient and cost-effective results.”
The study forms part of the broad array of research conducted by the Fraunhofer IAO in the mobility arena. The Institute is carrying out numerous studies to determine how people choose to be mobile, both now and in the future. It uses its expertise in this area to help companies and institutions introduce new business models and efficient processes.

DESY and MPSD scientists create high-order harmonics from solids with controlled polarization states, taking advantage of both crystal symmetry and attosecond electronic dynamics. The newly demonstrated technique might find intriguing applications in petahertz electronics and for spectroscopic studies of novel quantum materials.

Nano- and microtechnology are promising candidates not only for medical applications such as drug delivery but also for the creation of little robots or flexible integrated sensors. Scientists from the Max Planck Institute for Polymer Research (MPI-P) have created magnetic microparticles, with a newly developed method, that could pave the way for building micro-motors or guiding drugs in the human body to a target, like a tumor. The preparation of such structures as well as their remote-control can be regulated using magnetic fields and therefore can find application in an array of domains.
The magnetic properties of a material control how this material responds to the presence of a magnetic field. Iron oxide is the main component of rust but also...
Due to the special arrangement of its molecules, a new coating made of corn starch is able to repair small scratches by itself through heat: The cross-linking via ring-shaped molecules makes the material mobile, so that it compensates for the scratches and these disappear again.

Researchers at Chalmers University of Technology and the University of Gothenburg, Sweden, have proposed a way to create a completely new source of radiation. Ultra-intense light pulses consist of the motion of a single wave and can be described as a tsunami of light. The strong wave can be used to study interactions between matter and light in a unique way. Their research is now published in the scientific journal Physical Review Letters.
"This source of radiation lets us look at reality through a new angle - it is like twisting a mirror and discovering something completely different," says...
