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
passive and privacy-respective way and manually tracking pedestrians to
extract their trajectories, head orientations, and information about their group
membership.

These field data were collected in Lyon, France, between July 2020 and January 2021
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/

FORMAT
The data are saved as text files, with each file corresponding to a different recording
place. The first line of the file is the header and explains the structure of each line:

1) ped_no: the pedestrian label (an integer)
2) group_no: the label of the group to which the pedestrian was associated, by visual
identification of group members
3) time: time point (in seconds)
4) x: first coordinate (in metres) of the position of the centre of the pedestrian's head at this time
5) y: second coordinate (in metres) of the position of the centre of the pedestrian's head at this time
6) theta: angular orientation (in radian) of the pedestrian's head, i.e., the orientation
of the line joining the centre of the head to the mouth

The data are free to re-use, but please cite the reference below (or the associated
published version) if you make use of them for academic or business purposes.
