I've noticed cameras on top of several traffic lights around here.

At first I thought that they might be red light enforcement cameras. But then I noticed that the cameras are not aimed at the intersection, where red light violations occur. The cameras are aimed down the street.

Also, I've not heard anything about red light enforcement cameras in this area, and in the areas that have them, they are publicized.

I then noticed that the pavement at these intersections does not have lines in it from having traffic sensors installed in the pavement.

Is there new technology that uses cameras to sense approaching traffic to change the signal lights to green?

dude, they're sensors to determine when to turn the light green.

not cameras.

They may not be cameras at all, but rather sensors to pick up the signal from authorized emergency vehicles to change the lights to all red.

Ask your city's traffic department what they are and how they work. I'm sure that there's an Engineer I who would love to explain it to you. Seriously.

They are normaly used to monitor traffic flow, and to try to adjust the signals.

Wouldn't be down around Lake Mead and Boulder in Henderson would it? Those have been there for a while, and we ARE WATCHING YOU..

There is traffic recognition software and vision systems that can alter the timing of the lights, and in reality, I first noticed cameras in Vegas about 8 years ago.....Metro keeping you safe.

Probably are for changing the lights.

Once people get used to them they learn to move up a little to change the "picture" so the light will change if it hasn't.

I thought that the sensors to change the light for emergency vehicles were those small black things on the traffic light with a couple of horizontal short black tubes on them (?)

Nope, this is in Fernley, 30 miles east of Reno

From a municipal site here in MI,



Can the cameras at the intersection see me?

No, the cameras detect a change in contrast in the area it is focused toward. It counts vehicles that pass under it and no video image is processed. The cameras do not have remote zoom or pan capabilities.

Holy crap! That is the middle of Nowhere! My wife's grandmother and her half brother and sister live in Silver Springs.

What the fuck would anyone want to watch in Fernley

Yep. We've got one intersection in town with them and at night they don't pick up my dark colored car. It's faster to get out, run across the street, hit the ped. button and rush back to the car before the light turns green.

But I have been temped to aim my genuine, imitation surefire flashlight at the sensor and see what happens.

They're Opticom sensors.

They are cameras, They replaced the old magnetic loop detectors in the pavement. They are adjusted for zones and are the eyes of the controller. The controller can be adjusted for time of various lanes. Simple traffic actuation, sometimes they do act up or don't pick up small cars. It can get wild when paving through an intersection. By the way I work for Texas Dept of Transportation.

They're watching you.

Tinfoil hat on.
