Field data about pedestrian trajectories and head orientations in diverse situations during the Covid-19 pandemic

This dataset was obtained by recording pedestrian crowds in diverse settings in a<br> passive and privacy-respective way and manually tracking pedestrians to<br> extract their trajectories, head orientations, and information about their group<br> membership. These field data were collected in Lyon, France, between July 2020 and January 2021<br> at diverse times during the Covid-19. Details about the settings can be found in the reference below, as well as on the webpage https://seppieton.herokuapp.com/scenarios/ <strong>FORMAT </strong><br> The data are saved as text files, with each file corresponding to a different recording<br> place. The first line of the file is the header and explains the structure of each line: 1) <strong>ped_no</strong>: the pedestrian label (an integer)<br> 2) <strong>group_no</strong>: the label of the group to which the pedestrian was associated, by visual<br> identification of group members<br> 3) <strong>time</strong>: time point (in seconds)<br> 4) <strong>x</strong>: first coordinate (in metres) of the position of the centre of the pedestrian's head at this time<br> 5) <strong>y</strong>: second coordinate (in metres) of the position of the centre of the pedestrian's head at this time<br> 6) <strong>theta</strong>: angular orientation (in radian) of the pedestrian's head, i.e., the orientation<br> of the line joining the centre of the head to the mouth <br> The data are free to re-use, but please cite the reference below (or the associated<br> published version) if you make use of them for academic or business purposes. <strong>REFERENCE </strong> Garcia, W., Mendez, S.
