Based on subjective impressions and anecdotal evidence, Austrian public and private life came to a sudden halt. Here we assess the effect of the lock-down quantitatively for all regions in Austria and present an analysis of daily changes of human mobility throughout Austria using near-real-time anonymized mobile phone data. We describe an efficient data aggregation pipeline and analyze the mobility by quantifying mobile-phone traffic at specific point of interests (POIs), analyzing individual trajectories and investigating the cluster structure of the origin-destination graph. We found a reduction of commuters at Viennese metro stations of over 80% and the number of devices with a radius of gyration of less than 500 m almost doubled. The results of studying crowd-movement behavior highlight considerable changes in the structure of mobility networks, revealed by a higher modularity and an increase from 12 to 20 detected communities. We demonstrate the relevance of mobility data for epidemiological studies by showing a significant correlation of the outflow from the town of Ischgl (an early COVID-19 hotspot) and the reported COVID-19 cases with an 8-day time lag. This research indicates that mobile phone usage data permits the moment-by-moment quantification of mobility behavior for a whole country. We emphasize the need to improve the availability of such data in anonymized form to empower rapid response to combat COVID-19 and future pandemics.","lang":"eng"}],"conference":{"end_date":"2020-12-13","start_date":"2020-12-10","name":"Big Data: International Conference on Big Data","location":"Atlanta, GA, United States"},"quality_controlled":"1","publication_identifier":{"isbn":["9781728162515"]},"month":"03","main_file_link":[{"open_access":"1","url":"https://arxiv.org/abs/2008.10064"}],"year":"2021","oa_version":"Preprint","oa":1,"doi":"10.1109/bigdata50022.2020.9378374","article_processing_charge":"No","day":"19","author":[{"first_name":"Georg","full_name":"Heiler, Georg","last_name":"Heiler"},{"first_name":"Tobias","full_name":"Reisch, Tobias","last_name":"Reisch"},{"last_name":"Hurt","first_name":"Jan","full_name":"Hurt, Jan"},{"last_name":"Forghani","full_name":"Forghani, Mohammad","first_name":"Mohammad"},{"last_name":"Omani","full_name":"Omani, Aida","first_name":"Aida"},{"first_name":"Allan","full_name":"Hanbury, Allan","last_name":"Hanbury"},{"first_name":"Farid","full_name":"Karimipour, Farid","orcid":"0000-0001-6746-4174","last_name":"Karimipour","id":"2A2BCDC4-CF62-11E9-BE5E-3B1EE6697425"}],"_id":"9253","status":"public","department":[{"_id":"HeEd"}],"type":"conference","scopus_import":"1","publication":"2020 IEEE International Conference on Big Data","page":"3123-3132","citation":{"apa":"Heiler, G., Reisch, T., Hurt, J., Forghani, M., Omani, A., Hanbury, A., &#38; Karimipour, F.
