The data recording was performed by a Pioneer 3-AT mobile robot equipped with the Velodyne VLP-16 at an approximate height of 0.8 meters.
During the data collection, the robot remained stationary in a T-shaped junction, which allowed its sensors to scan the three connecting corridors simultaneously, covering a total area of around 75 m².
The data collection was performed during ~10/12 hour-long sessions starting before the usual working hours (usually from ~08:00 to ~20:00). 
The resulting dataset is composed of 14 data-gathering sessions recorded over the span of four weeks.
A typical session contains approximately 30000 detections (at 0.5 Hz) of people walking in the monitored corridor.
