[Vienna, 2 July 2020] In times of uncertainty, people not only need reliable information. Data must also be presented in a simple and understandable way. Researchers at the Complexity Science Hub Vienna (CSH) now developed a tool which uses the well-known traffic light system to visualize worldwide trends in coronavirus infection. The “CSH Corona Traffic Light” shows countries in green, yellow or red based on the confirmed cases within the past two weeks.
A country is depicted in green if less than 1 person per 10,000 inhabitants is tested positive. Yellow shows countries with 1 to
“With the Corona Traffic Light people see where they can travel more safely,” says Stefan Thurner (CSH, MedUni Vienna), one of the developers of the tool. “Travelling to or within countries colored in green is considered to be rather safe. I would be cautious with yellow countries–and red is out of the question,” states the complexity scientist.
Second wave ahead
During the last couple of days, more and more countries turned from green to yellow again, even countries that previously managed to keep the virus under control, such as Israel or the Western Balkans. “We must face it: The second wave is just around the corner or already beginning in many parts of the world,” Thurner points out. As the holiday season is about to start, it becomes even more important to closely watch these developments over time.
The worldwide Traffic Light is the expansion of an earlier project. “We first developed the Traffic Light for Austria,” says Stefan Thurner. The Austrian “Corona-Ampel” published in late April, shows infection trends in much more detail, broken down to every political district in Austria. The tool was in great demand right from the start. “People really want to know what is going on in their region. If we provide reliable information in an easy way, they can make their own well-informed decisions,” Thurner concludes.

About the Complexity Science Hub Vienna (CSH):
The mission of CSH Vienna is to host, educate, and inspire complex systems scientists dedicated to making sense of Big Data to boost science and society. Scientists at the Hub develop methods for the scientific, quantitative, and predictive understanding of complex systems. Focal areas include the resilience and efficiency of socio-economic and ecological systems, network medicine, the dynamics of innovation, and the science of cities.
The Hub is a joint initiative of AIT Austrian Institute of Technology, Central European University CEU, Danube University Krems, Graz University of Technology, IIASA International Institute for Applied Systems Analysis, IMBA, Medical University of Vienna, TU Wien, VetMedUni Vienna, Vienna University of Economics and Business, and Austrian Economic Chambers (WKO).
