“Last year, traffic-management authorities there started using facial recognition to crack down. When a camera mounted above one of 50 of the city’s busiest intersections detects a jaywalker, it snaps several photos and records a video of the violation. The photos appear on an overhead screen so the offender can see that he or she has been busted, then are cross-checked with the images in a regional police database. Within 20 minutes, snippets of the perp’s ID number and home address are displayed on the crosswalk screen. The offender can choose among three options: a 20-yuan fine (about $3), a half-hour course in traffic rules, or 20 minutes spent assisting police in controlling traffic. Police have also been known to post names and photos of jaywalkers on social media.”
