 * Yes it did have one originally but it was almost immediately deleted - Wikipedia works in curious ways its wonders to perform.  Velela  ♥

Toronto had the first computer controlled system
There seems to be no coverage on traffic light systems that are timed out by computers that calculate the traffic flow using the sensors in the ground. Toronto was the first city to convert to this system in 1963. -  ʄɭoʏɗiaɲ  τ ¢  17:37, 9 June 2010 (UTC)

but it does have a great ice cream bar.

Detectors
Why does the picture of the saw cut loop detector appear to have a yellow light at the top? The traffic lights I've seen always have red at the top, and yellow in the middle. Color distortion in the picture?

Also, it would be nice to have more information on the non-inductive detectors. Like: what do they look like, how can you tell when there is one, and what can make them not work. (We have a defective sensor in a nearby stoplight. I've see it malfunction twice, both times around 7 PM for east-bound traffic (other directions are unaffected).  I was wondering whether the sun shining directly into some kind of optical sensor could casue it to fail, but this article doesn't tell me enough to know.) Mcswell (talk) 03:56, 16 June 2014 (UTC)


 * Regarding the colors of the photo. That intersection uses LED lights and red is the top one. I am also not sure why the color came out like this. My only possible theory is that the angle of the LED light bulbs on that red light was just perfectly pointed to my iPhone camera and the high intensity of the LED light makes my camera capture the image with distorted color of the LED light?? You can see that the SUV in the front has the correct red color on its rear lights. Z22 (talk) 14:00, 16 June 2014 (UTC)


 * Added a pic of a non inductive detector (an old treadle), which is here in California. There are not too many of these left. Northwalker (talk) 19:22, 28 December 2016 (UTC)
