#JustCurious What are the white cameras on traffic lights?

#JustCurious What are those cameras on traffic lights? Carly was #JustCurious what the little white camera on top of a traffic light do. Here's the answer:

REGINA — Next time you stop at a red light, look up. You might notice (on some, not all) a little white camera.

Carly was #JustCurious what exactly those cameras do and why they’re there. The City of Regina says they’re vehicle detection cameras. They’re used to help with traffic flow at intersections. They monitor cars in designated areas and adjust the traffic signals accordingly. So, it’s supposed to help alleviate congestion in some areas.

You can be the judge on if that’s working. The cameras are not spying on your activity in the car. They will however, try to change the lights for emergency vehicles to let them through right away.
