Out in my area New Hampshire out by Dartmouth College, they have remote overrides for the lights now with cameras at intersections, so that if a sports event lets out etc, they can remotely control the lights to ease the traffic congestion.
I kind of miss the prior setup they had though because there are 2 lanes that turn left onto a highway on ramp that forces people to single file too soon, and people do not want to let others in etc, and the prior setup they had you knew the pattern of the lights from driving it daily and so when the light for the oncoming traffic gets its yellow, you have 3 seconds of red for them and then your left turning lane goes green.
So sort of like how drag racers watch the tree to know when the light is coming to hit it, you could time 3 seconds and nail the gas peddle sometimes 1 second before the light goes green for you and have the lead onto the ramp without getting jumbled up in the mix of people fighting for asphalt and no one wanting to let you in if you are the first at the light with another vehicle to the side of you which is also going to fight for the asphalt.
Some people would say, dont be aggressive and let someone else have the lead, but this is like a stampede when the light turns green, and if you are not going with the flow you are a problem to the flow and can get trampled/have an accident by being an obstacle instead of part of the flow.
If anyone beats me to the lead I let them go ahead, but have my nose of the car close to their tail so that someone else overly aggressive behind me doesn't try to pass me with no asphalt to allow 2 cars side by side.
With the new lights that can be remote controlled the switching doesn't follow a known pattern and so you cant have the advantage of hitting the gas hard 1 second before it turns green, and then the delay time of everyone else who is waiting for green to let you have the lead.
I am guessing that these are also computer run so that the patterns can be preprogrammed differently ahead of time as well as allowing the police to be reactive with an manual override if needed etc.
For the most part its a good system such as if someone breaks down or has an accident its caught on camera etc and they can react faster. And without knowing the green is coming I am not caught on camera leaving my red 1 second before it turns green for others...LOL
