This dataset comprises street-level traces of traffic flow as reported by Here Maps™ for 13 cities of Romania from 15th . of May 2020 and until 5th . of June 2020 . This covers the time two days before lifting of the mobility restrictions imposed by the COVID19 nation-wide State of Emergency and until four days after the second wave of relaxation, announced for 1st . of June 2020 . Data were sampled at a 15-minute interval, consistent with the Here API update time . The data are annotated with relevant political decisions and religious events which might influence the traffic flow . Considering the relative scarcity of real-life traffic data, one can use this data set for micro-simulation during development and validation of Intelligent Transportation Solutions (ITS) algorithms while another facet would be in the area of social and political sciences when discussing the effectiveness and impact of statewide restriction during the COVID19 pandemic.
