Wow! You answered a question I’ve had years living here in Austin TX. I did not know what those little fins were on the ends of the metal poles. They’re on nearly every traffic light here in the city. I thought maybe they were signs that face up so that aircraft could read them. Seemed silly, but I had no other explanation until now-wind dampeners to minimize pole shaking. Thanks!
I would have thought that the ped buttons are normally open until pressed. This way when the button is damaged like that, the wires (unless shorted by the damage) would NOT be calling. EDIT: I would also assume there would be a logic circuit that would monitor the continuity so if the wires are shorted, or someone/something is leaning on the button for a long period of time it would "disable" any future calls.
I would assume it's done this way so that way when this happens as it has here, pedestrians still have a chance of getting a walk symbol.. otherwise, depending on how the intersection is programmed, they may never get a walk symbol as they have no button to push, And the controller would have no way to know know that the button is no longer available.
So you can actually win sometimes. I have survived 2 accidents at work. The first one I (my body not the vehicle) was struck by an SUV while working on street lighting on an off ramp from a major highway. The other time I was changing a green LED on a traffic light and a semi smashed into my bucket while I was in the air.
EDI 1600 MMU = Malfunction Management Unit. CMU is a different piece of equipment. Bummer the pedestrian didn't make it, never a good day when that happens...
I will check with you and see how you found out how a day you were there! Did your wife tell you what day you were there. It seems to be most of us have to find out from one of our family members. Be careful with all the weird drivers out there we want to make sure you're around with us and you see your kids grow up
Just curious. Wouldn’t it be cheaper to have the equipment networked so that some of the tasks could be done remotely and quickly? Time could be set automatically on all devices so they are synced, you could read logs and adjust the camera zones remotely.
Some intersections are.. but not all. It would be up to the agency responsible for the intersection to whether they have the infrastructure in place to do that, and choose to pay to have that done.
NO surprise because drinking, drugging, driving and texting. And then mix in eating, shaving, makeup, reading. 99% of Accidents are Driver Inattentiveness🤪👎
A lot of american road design is bad, including old highways and parkways that weren't updated when their speed limits were raised, and the unnecessary widenings when roads get updated
NIST provides RCC so that devices can capture accurate time over radio frequencies. If intersections aren't timed accurately, it can cause traffic flow issues between adjacent intersections.
It's an interesting device, coming from a software developer standpoint. The controller drives the signal lamps based on inputs of who's waiting for what, or timers, or both. The conflict monitor literally monitors the voltages on the lamps themselves, and compares it to a graph of what's allowed at the intersection, and if it determines that there is a "conflict", it turns the entire cabinet into "signal flashing" mode. ie it prevents stuff like a four way green light.
Love your channel, Steven. Just curious... Rather than just equipment swap, will you ever get into the design aspects? I'm a programmer, but would love to understand ladder logic better. Thanks. 🙏👍💯🎯
I've been watching his channel for a couple years now and I work in the industry as an electrical engineer/PCB designer. Love getting to watch our equipment that I helped design being used in the field. FYI, If you're anywhere down near Plano/Greenville Texas we have several openings for engineers and other positions as well.
Would be nice if the truck was recorded and got tagged for the repair costs instead of the tax payers. Majority of semi drivers are artists but there are those like with the smaller vehicles that need to pay for their mistakes and damage.
@@napsterbater I saw some yellow/green lights above cabling, which is indicative to Tx/Rx transmissions, _usually_ associated with RJ45 ethernet jacks, but doesn't have to be. Most modern controllers _are_ ethernet equipped.
@jbsimmons54 the flashing yellow you see above the green cable at the first intersection on the conflict detector, is referencing data transmission and receiving to and from the sdlc connection to/from the traffic controller. So they have communication with each other. It's not ethernet in this particular case. You will also see some lights and ethernet cables on the video detection controller, but those are mainly connections to the cameras themselves and it's showing link and data for them, and it kind of does look like it also has a data activity light for the sdlc connection. It also has back to both the conflict detector and controller. Now again there are some intersections depending on the area and the agency involved and everything that do have actual internet connections but the ones shown here do not.

Those control boxes look very expensive with all of the controls

I'm a traffic signal apprentice. Your videos are very informational and get me excited to start working with cabinet components. Keep em coming!
really interesting! thanks for sharing. as a software engineer, it's fascinating to see how much complexity there is to this stuff.
Great job explaining how signal intersections operate! Appreciate you taking us along.
Absolutely love these, but I gotta do this.. "You have to change the Toms"

Are they not networked so you can pull logs remotely or calls for help when needed?
They need you in Houston to fix the 1100 some odd number of traffic lights that are out of service after the hurricane Beryl hit.
LED traffic lights have put the light bulb crew out of business, one less thing to worry about.
Havent watched the vid, but i know its going to be fire 🔥

Nice work to get them commuters flowing in peak times 😊
Wouldn't it be better and safer to be able to check logs, etc. from a remote location via the internet?
Hey there. I’m new with your videos but really enjoying them. Do you work for a city or state? Or are you a contractor that someone hires??
Hurricane beryl blew out all of my cities light too lights made lights weird moved poles

If it said the last error was July 4th, and the controller thought it was July 5th, wouldn’t that have meant it failed over the day prior?
I think id rather work on them at night, typically less traffic to deal with.
Do you work on traffic lights in Waco, Texas?
Quick question for you how come your caution strobes on your vehicle or green as opposed to Amber you may have been asked this question before

Can these controllers use GPS or NTP to automatically keep their time synced?
NIST provides RCC so that devices can capture accurate time over radio frequencies. If intersections aren't timed accurately, it can cause traffic flow issues between adjacent intersections.
What is a conflict monitor
It's an interesting device, coming from a software developer standpoint. The controller drives the signal lamps based on inputs of who's waiting for what, or timers, or both.

Generally speaking, Pedestrians take very Unnecessary Risks but you also have to take into account the possibility of mental health issues. 🤔🙏
Date/time should be set/sync'd to local internet clock, no...?
You assume this particular cabinet has any kind of internet connection in the first place.. doesn't appear so.

Hi
Time and date important because if you gone then it have a problem, if you not have right date then it hard to tell it was new or old.
