When there is no one in the left turn lane, why have it work? We have a signal at an intersection that they've recently made even dumber. The more traveled street used to have priority with the less traveled street getting a green only when there were more than two or three vehicles waiting and it would only allow those vehicles a green light. Now, even when one vehicle is stopped, the light goes through its entire cycle - Green for one direction, then green for the other direction, left turn signal (even when no one is there to turn left) while backing up traffic on the more traveled street - all for one vehicle. It has gone from a 1 to 1.5 minute delay to a 3 to 3.5 minute delay.

When there is no one in the left turn lane, why have it work?
Because I am coming. They should be waiting for me to come through.
The way the intersection is set up now, I wait roughly six minutes to make a turn, even though there is no opposing traffic for most of that time.
Maybe they could take out the turn signals entirely, and make it a left turn lane on the regular green.
Now, even when one vehicle is stopped, the light goes through its entire cycle - Green for one direction, then green for the other direction, left turn signal (even when no one is there to turn left) while backing up traffic on the more traveled street - all for one vehicle.
Yes, then you know what to expect. If they're waiting for several vehicles to appear at the less travelled intersection, that may take five or ten minutes. That's too long to wait, even if there on more cars going in the other direction.
The sensors listed in the article have the potential to work very well, but the set of assumptions one begins with can have a negative effect if not thoroughly thought-out.

The light shouldn't go through the entire cycle for one vehicle. Also, here, you can make a left on green when there is no oncoming traffic - you don't have to wait for the little arrow.
I believe you are correct - I mean here too? However turning into a left turn lane does trigger the light cycle. So with that, if I turned on a green light without waiting for the green arrow, a few minutes later the single would stop traffic for a car that already left minutes ago - maybe thats what your seeing is an action that happened minutes ago?
Anyway. When Marg was here she mentioned about Hawaii's heavy use of Green Arrow Stop Lights. And it does promote faster traffic coordination then say Toronto which lacks green arrow usage.
