I knew of these, but I've only ever seen it done once in the field; I saw a police officer handling a traffic light at a convention center where there were _thousands_ of cars trying to turn left into the venue. I never knew the exact mechanism, but now I do! Thanks!
My personal cabinet had the switches, but no plug or button for manual advance. Since I wanted to have this feature in operation in my cabinet, I went to Radio Shack to find a suitable button. I had to map out the inputs for the button on my panel and solder the button in on the back of the police panel. It's nice to have that feature on my cabinet as I can use it for testing purposes if I need it.
It also looks like the same type of button they gave me on my IV last time I had major surgery so that I could request pain meds myself (within limits, of course)
Fun fact: we call the button to control the light a "pickle" and will commonly say we are "pickling the light" when taking manual control. Yes, this also results in the joke that we are "playing with our pickle."
In that case, the cabinet should be constructed such that the door can't be closed with the hand button still plugged in, and the "AUTO" functions restored when the door is closed.
@@sferg9582all it needs is a wedge that will push the hand-auto switch to the auto position when you close the door. Alternately you could have a microswitch that overrides the hand-auto switch to tell the system that it should be in auto when the door is closed.
You can eliminate the hand/auto switch. You can wire the push button jack for manual operation when the push button is inserted. Requires a stereo jack - not mono.
I used to travel to Jacksonville FL every couple months in 2012 to 2014. Many busy intersections had cops near these boxes. Had the wire thru their driver’s door window. Now I understand. I think they may have been using the wire into their laptop, but I may be wrong on that.
Imagine you’re going full speed limit towards an intersection with a green light and then three seconds before you cross the line it starts flashing red
I love this it's like sesame Street with attitude you do a great job! Take good care of the wife and the family oh yeah and the Jeep after that last statement I bet your wife can control you with a push of a button. Lol if she turns off the TV.
Seems quite risky to change from Out to On and it just continues as nothing happened. When someone approaches the intersection and it changes directly to Red while someone else gets Green immediately, I feel like accidents are quite likely to happen. Here in Germany when you turn a traffic light on, it will also turn Red for the side road. But it stays dark for a while (lenght depending on the intersection) on the main road before turning Green. This way when turning lights on, when someone passes on the just appearing Red light, the other traffic doesn't see Green yet and are still in special attention mode since the lights are off
As pedestrians don't pay any mind to pedestrian signals, that's not a problem. (I'm firmly convinced pedestrian signals are a complete waste of money.)
Always enjoy your videos. I wanted to ask your opinion here. In our town, there is a signal-controlled intersection at an exit from Walmart onto US Highway 31. Whoever has the authority to set the timing sequence (I've called the mayor and apparently he doesn't have the authority to improve this situation.) has the exiting Walmart traffic wait for 90 seconds before getting a green light to leave Walmart and the green is on for 30 seconds. Most afternoons and all day Saturday and Sunday, the line can have 25 or more vehicles backed up waiting for green light. Any suggestions? Thanks.
Do you have to deal with traffic lights at Railroad Crossing? If so, how do you maintain the traffic lights, for example, to clear the lanes for approaching trains?
I'm not Rob, but I can tell you that it's been determined what pattern they want the lights on when trains pass. The controller receives the signal from the railroad's controller and treats it as a preempt. The designated pattern of traffic lights is displayed until the train passes and the controller receives an "all clear" signal. There may be some different movements permitted, but certain movements will be completely blocked.
The RR equipment tells the traffic signal controller if a train is coming. The bespoke programing of the traffic signals then takes over according to engineering and safety need.
During the design of the signal, a giant chart is made for every scenario when a train comes. It gets even more complicated when that intersection has ped crossings and/or EVP. Those scenarios are programmed into the controller so it knows what to do when a signal is received from the RR. Where I work we call them choo choo charts.
@jameskinglion I don't know how it works in the US but here in France every crossing comes with a switch that will turn on the flashing red lights, bells and lower the gates just like if there was an approaching train. That way maintenance can close a crossing if they need to. And cars just wait or divert if the crossing is due to stay closed for an extended period. (Of course in that case there will be signs telling just that)
@@psirvent8 Such things exist here in the States too, called "Test Switches," but they have largely disappeared. Most crossings can be manually activated by accessing the signal bungalow or cabinet, or opening a gate mechanism cover and adjusting a test nut.
Interesting and cool vid. The one person that ran the red light. Anyways there was an accident where a car ran into the box and they did get it fixed but it was on flashing where it would be a flashing red light. They did get it fixed.
I would love to know more about how traffic intersections know/detect oncoming emergency vehicles and if those vehicles can control the traffic signals when they aren't able to access the police panel. Loving the content! These are all things I've been wondering since I was a kid haha
Preemption control...Emergency vehicles must be equipped with the "SEND" equipment and the traffic signals must have the "RECEIVE" equipment for it to work. Can be strobe or GPS activated from the emergency vehicle. The controller must be programmed as well so when it receives a call from the preemption receiver, it knows which way to give a green light and for how long. Great question
@@streetsmartstraffic All good, bud. What's funny is I truly hate traffic lights when I'm in traffic lmao, but I am always fascinated by their technology 😆
@@digitalchaos1980 I'm no different! Been working on them for 20+ yrs and if I'm sitting in traffic in other places than the ones I maintain, i start complaining to my wife how I could fix that, they should time this better, etc... I'm very impatient! LOL
I bet the keys to that cabinet are generic. Disgruntled employees could disappear with custom-made keys, and the city might run out of them if too many get lost.
Does your city use Opticoms? How do they interact with the box? Just override everything? I remember the rare cases when ours did work it was like a dance party in the center of the intersection with white lights and all four sides turned solid red.
wish cops in my area would bother to use the hand control, they set them to all flash and then do some sort of interpretive dance in the middle of the intersection, because it sure as hell isnt anything resembling directing traffic.
Not that I'm aware of. There used to be issues with LED signals not generating enough heat to melt snow off the faces like incandescents did, but I think that problem has been largely address (with on-demand heaters).
I’ve came across numerous situations where on the way to work in the very early morning, this one light takes ages to turn green on a turn (possibly on straight too).
I'd rather have it dispense some pain meds. BTW I looked a 2 signal control boxes here in Los Angeles and there is no "small access panel" on the ones I looked at.
Q: Are there accommodations for signal control cabinets to accept a generator input? Having retired from emergency services a while back, if there were power outages for extended times, manpower was dispatched to the intersection to either set up stop signs, or we would be tasked to manually controlling the intersection with officers in the traffic.....dangerous to say the least. I was arguing all the time that there should be the option to plug-in a generator during the outage to safely operate the intersection without putting humans in the dangerous areas of the roadway.
In my area, I know of one super-critical intersection that doesn't seem to lose power when area lights go out. I suspect they have a battery system inside the cabinet. I don't know how long it will last.
Yes. There's an intersection a few miles away from where I live in South Florida that has the ability to run off a portable generator when power fails.
The rarity of needing a generator input probably doesn't justify the expense of installing a dedicated, weatherproof inlet for it. If it would be necessary, you can jsut open the cabinet and re-wire the signals to use the generator supply easily enough.
@@jovetj When a town or county or state takes the cost of an electrical box over the life of someone out directing traffic, it becomes a tragedy if someone gets hurt or killed because of a few bucks. Wiring up something as a bypass is reckless, dangerous and probably will lead to litigation.
@@sferg9582 "A few bucks" adds up across dozens or hundreds of intersections. Contrary to your belief, lives or risk thereof do have "a price" and sparing no expense on "safety" is neither practical nor feasible. Reckless and dangerous? Really?
I really like your video this a was a great demonstration of the traffic controller features. Im not sure how common this is but i know ive seen law enforcement place signals in flash or even during power outages the signal gets stuck in flash and doesn't return to normal operations. I was told this is also a fail safe if the controller detected a conflict with the light cycles. But how does this get reset? Someone told me theres a reset button in the bottom of the cabinet
Getting those boxes installed with all the tech stuff in it is easily a couple thousand dollars. It would be so easy for some hooligan to come along and destroy it...
What I'd like to know is how these high tech, complicated and very expensive traffic control systems are able to detect me approaching an intersection and cycle at the right time so that I am always the first vehicle at the dad-gum red light every stinkin' time!!!!!!!!
Some intersections has like a pressure thing under the concrete. it triggers a switch similar to the ped crossing button to let the light know someone is there and can change its timer accordingly.
Sometimes it looks like he has a bit too much fun with the traffic light. Can't imagine the drivers being too impressed... Why such a long red light on a dead cross street.
My initial thought was the police officers remote button. The Kia boys are sure to escape the helicopter with a artificial intelligence heat sensing camera, the boys left clueless upon their capture. How are Engineers making police chases safer such as stopping cross traffic from getting green lights, spike strips built into the popular Escape Route with never miss absolute perfect timing.. You can't watch all the cameras at once especially when there's so many, such a bore. How is artificial intelligence being applied? The camera show you enter the highway at the third intersection and exit at the 12th able to calculate the average speed of every vehicle. And who doesn't want the traffic app on their phone, that works in real time perhaps suggesting the best speed for a green light based on where Google knows you're going. GPS can see what no officer can see if you're perhaps not safe to drive. Soon they will have a button for all the new vehicles, if only Kia had the button today.

messes with traffic to show off the manual controls for a video*. ... and "we're just testing out everything and making sure everything works here in this traffic signal controller cabinet...." Don't get me wrong, I enjoyed the video, and maybe it was a test out after a service call, but if so... well, lead with that; cause it comes across as a CYA comment at that point. *not withstanding that it's ostensibly instructive/informative in nature.
Every city and state has the chance to make and use 'city keys' in the US a bunch have kept the old time forged skeleton key from police/fire pull boxes, telegraph equipment for the Access Point While its not illegal to 'own' these .... using them can be problematic, replacements are all over ebay and other internet sellers. I have found most places have updated different 'Cabniet' keys for the main box to protect the valuable/sensitive equipment inside. all jokes aside :) own a piece of history if you want!
we have similar in the UK, but is abused by the local council, they authorise absolute prats to cause chaos at "events" at the local stadium, this feature should NOT exist
Everyone’s like “come ON!!!!!!”😂
😂😂
WHY IS IT BLINKING?
WHY THE FU*# DID IT TURN OFF
I wonder what goes through peoples minds when there going up to the intersection while he is flipping the switches back and forth
Probably "that was quick."
That was weird...must be maintenance inspecting the lights.
Yes I would
would think " what is this idiot doing with the traffic lights?!?"
I know right but they should problay say that was real quick
I knew of these, but I've only ever seen it done once in the field; I saw a police officer handling a traffic light at a convention center where there were _thousands_ of cars trying to turn left into the venue. I never knew the exact mechanism, but now I do! Thanks!
Be careful with that corded push button. You might accidentally call for the nurse.
Or start a powerpoint presentation.
I accidentally just voted.
Great demonstration of the use of the interval advance switch. Good job showing the controller as well. Well done!

It's nice to have that feature on my cabinet as I can use it for testing purposes if I need it.
You went to Radio Shack?! Is this comment from 1995?
I wish our local PD know about this. Way safer than standing in the intersection with those "wands" things.
Sometimes you have to get out there and get dirty. I know first hand.
that button looks like the same one you would find at a mobile hearing testing center with the 1 inch plug at the end
It also looks like the same type of button they gave me on my IV last time I had major surgery so that I could request pain meds myself (within limits, of course)
Fun fact: we call the button to control the light a "pickle" and will commonly say we are "pickling the light" when taking manual control.
Yes, this also results in the joke that we are "playing with our pickle."

I've seen the police in montreal use the manual control during rush hour to clear out the main roads.
They use manual control here after a football game, when there’s tons of vehicles and they’re trying to keep it moving somewhat.
No way he actually ran that red light 2:04
Might happen when a RUclipsr is standing there randomly changing the signal phases while cars are using the intersection.
@@sansaratechlol
I just learned how to control traffic lights with a button, hmm what to do with my newfound knowledge
Build a wireless version and never stop in traffic again.

Sometimes the cops get a hold of a Two Key and know how to reset the Conflict Monitor to get the Signal off of Flash.
Glad to see it with the hand control of the traffic lights by the police when there is a need to be doing it in Case of a accident
Or for a motorcade or other event that the police need traffic control.
Have you ever had to replace one of these boxes when someone runs off the road and wipes them out?
Plenty of times!
