- The site gives cigarette butts per 100 m² as an example of density, making routes comparable across streets and dates.
Field notes
The page distinguishes density from raw counts: its example is cigarette butts per 100 m² on a particular street segment and date. It describes surveys from a walk-along cart as well as installation on sweepers already in service, and says the camera records distance travelled alongside pavement images. The image-recognition and privacy details are presented as product descriptions; the homepage does not include deployment examples or performance results.
