The amount of knowledge, skill, and experience displayed in so many of these videos impresses the hell out of me. I just got recommended one of your videos for some reason and I've completely fallen down the rabbit hole. I think I've watched 10 so far tonight. I worked in the software development side of industrial automation decades ago, so a lot of the terminology is familiar. It's really cool to see the practical application of some of the software I contributed to and how it has evolved from the old days.
when I was a kid back in the 60's the Traffic control boxes used mechanical relays and timers. and I remember going into town for eve walks with my parents. and while waiting for the crosswalk light to change, I would always put my ear to the control box and hear clink clink clunk clack clank noises from inside. always wanted see inside of one of those control boxes when I was a kid, but now I get to see inside of the modern electronically controlled ones, in your video Thanks! 😀👍

I wish I had access to these type of videos when I was a kid, back in the 90's. I was fascinated with how the signals worked, but could not find info on the systems in the early days of the internet. Learning about how the induction loops worked and the LED replacement issues (Green was not reliable when they started doing it, so they still used the yellow/blue trick) when they were the brand new thing on traffic signals is what got me into Electrical Engineering. Keep up the videos, don't get burned out!
Been following for awhile and subscribed... just amazing how much technology goes into traffic lights also enjoyed the video on the high mast lights... always wondered how the bulbs were changed or serviced... until travelling one time I say the light pack near the bottom and cables down the side of the pole and figured they were winched. Thanks
Just happenstanced to your channel and I was enthralled with your commentary and review of these out of sigh out of mind devices!! Great and through explanations. I really enjoyed your content.. gained a new sub tonight! Happy 4th!
Hey man! Love your videos! So, the Polara buttons automatically adjust the volume with ambient noise from a built-in microphone. You can disable this via the app, but it is a pretty nice option if there is loud traffic or noise around. I've had a little fun yelling at the buttons and they start practically blaring out the commands lol. Just thought I would throw that out there!
Would also been cool to see how the flashing amber signals prior to a traffic signal attached to signs that usually read "prepare to stop when flashing" or something similar function.
Great work putting together these highly informational videos. In your future videos, can you talk a little bit about your educational training and career path which helped you build skills necessary to do the work you are doing with signals and other highway related electric devices. This may be helpful for younger folks who may be interested and want to get started in this path.
Those double mast arm poles are pretty interesting... we don't build any of those in CA. I always comment on different styles of TS systems and street lighting while driving through the states and it drives my wife nuts!
That’s funny, CALTRANS has their own standard for traffic control cabinets very different from the NEMA TS2 cabinets seen in these videos. California always loves being the odd state. Now I know that carries over to mast arms😂.
Do you use signal preemption at any of your locations? It would be nice to see something about that. For first responders and for train - traffic control interface.
I wish you would come to Schyulkill County PA and do our traffic lights. We'd do better with a traffic cop and whistle than what we have now. We're given grant sfor millions of dollars to revamp intersections and they basically just re-pave the road and paint new traffic patterns. It's quite disconcerting.
I love the photocell hookup. Inside the cabinet, it should last a whole lot longer than being outside. Does your crew only work at night due to the traffic load at night?
About what you said about using oversized wire on the load side on the meter can according to the NEC code book it’s fine to use oversized wire it just can’t be undersized
Great channel, you should do a big traffic Q&A. First question: it's nice to know that the ped crossing button does something most of the time, if you keep pressing the button, does it prolong or speed up the process at all?
How do the pedestrian count down timers know how long to count down for? Do they get the value from the controller or do you have to program them separately?
Keep up the longer formate. Could you go in to the histry of traffic lights over all and more detials on things like Opticom and other Emergency vehicle premption systems. One ore requwst, What part if the USAdo you work in. Thanks and Hapy 4th of July (Happy 248th Independance Day)
One thing I'd like to see and you may have covered this on a previous video but I am a fairly new subscriber to your channel, is how do they figure out the timing of satellites for example there's some intersections I go through where I live where they have a dedicated left turn lane and a traffic signal that indicates that but it's like way too short timing wise in terms of you can maybe get one or two cars through and then the light is already turning The left turn lane off, and also how does that work with the controller when you have like a dedicated turn lane but you also have opposing traffic
Folks have NO idea how Expensive every- thing is. Upgrading Equipment is Big Money when you figure everything. Some Towns Opt Not to use Electric Signals.🤔
Man I would love to see a video about the different detection technologies. I see this weird device on the mast that looks like a tiny bell shaped device. What is that?
Wood poles and span cables, is that big in the east coast/mid west? I've never seen a perminent intersection with span cables like that, only temporary big intersections that are under construction and need traffic movement.
How do you set the delay between 1 direction turning red and the other direction turning green? Here I think there is a 5 to 6 second period of time when all lights are red.
I’ve programmed a few intersections the all red time is usually 1-2 seconds. I’ve heard about some places with Red Light runners extending the time to 5-6 seconds. The timing is set in the controller under “Red Clearance”. What part of the states has this long of timing?
maybe a traffic light myths video? i see people flashing their brights at lights all the time and stopping on the back loop to get the signal to change faster etc.
Why do Signal Lights in the most busy or dangerous intersections not havesome kind of a back up power source? I am going to guess the reason is cost. alsodose any intersection you work , and radarn had, loop, Camera
was thinking the same. or maybe one of those metal barricades with a wide rail and 2-3 4x 8's to mount it on. but with enough space between it and the boxes to have room to work comfortably.
@@superdad2150 Safety! If anything is near the road it’s designed to be ran into in the case of an accident. Road barriers break so that all the energy from the car is absorbed into a barrier or in this case the cabinet before a person in the car does. Adding a concrete barrier may protect the cabinet, but it comes at the cost of putting lives at risk.
Just throwing it out there....shouldn't the ped button (the one next to the one you were testing) have been mounted on the other side of the pole pointing towards the walk way? We're dealing with alot of ADA compliancy right now and many times I'm making sure buttons are mounted on the same side of walkways. If a person was in a wheelchair, they would have had to go around the other side of the pole to hit the button and then come back around to enter the walkway....Anyway, great videos TLD! Almost 110k Subs!
I want to know how left arrows work like flasking yellows works can u make a video about that sometime this is my first time watching ur vids there cool
Great question! I drilled the hole for the breaker box and used the knockout on the meter which didn’t allow room for the meyers hub nut to thread on! Next time just drilling both!
One thing that does interest me, is as a ISP/Network provider. We can do 90% of our jobs remotely. Now I know that is not a valid item for you.... but, shouldn't all those systems have a central control ability? I think you have reporting - but not management. Because the likes of changing the beeps to countdown, aligning the cameras .... like that could be done remotely Any ideas why not?
I didn’t realize those pedestrian buttons could do an audible voice countdown. The ones around me in Rochester Mn. either say “(street name). Walk Sign is on to cross (street name)” like 8:03 or create the “machine gun” sound effect.
As a career of electrician, I think it wasn't a good choice that you actually were physically touching all of the lugs in the meter pan even though you know the power is off if not most electricians always treat everything as if it is hot but a curious homeowner will not go in their own meter and go start touching stuff and end up getting killed because they saw you touching it on your video.....

Don’t know if your gonna see this, but I’d love to see more long format content! Keep up the good work in the world of traffic lights Doc!

Excellent video thanks for sharing 👍 would love to see you wiring lights up on mast arms

I laugh every time I see pedestrians mashing the call buttons 50 times, thinking that's going to speed up the process. 😅
I absolutely love the long form vlog content, keep it up!
Just happenstanced to your channel and I was enthralled with your commentary and review of these out of sigh out of mind devices!! Great and through explanations. I really enjoyed your content.. gained a new sub tonight! Happy 4th!
Would love to see how various forms of preemption work (opticom/railroad/etc), if you happen to work on any of those
Same!
Same here!
I’ve learned so much about traffic signals from your channel, great job love your videos, keep up the great work 👍
Great swap over the new traffic lights in the Mississippi heat
How come they don't put concrete ballards around the meter base to prevent a car collision again ?
Enjoying the content.

I really appreciate the detailed explanation of what you're doing as someone who wants to start on the path of traffic light healthcare lol
Video Idea: Bell shaped traffic cameras
Would love to see really in depth phase control and conflict control unit operation/wiring, keep it up with the longer form content
Bro!! You're doing a great job! Enjoy the channel! Those who can't do, criticize… Got to love keyboard warriors… Happy Fourth!

I assume the double-arm poles are a cost-saving measure. It's not done where I live, either.
Love the longer videos. What does CCU stand for?
Central Control Unit. Its what communicates to all the ped buttons in the cabinet. Just trying to help out Traffic Light Doctor. He's a busy man!

I love the photocell hookup. Inside the cabinet, it should last a whole lot longer than being outside. Does your crew only work at night due to the traffic load at night?
Do you do any work with integrated traffic signals with railroad signal equipment?
About what you said about using oversized wire on the load side on the meter can according to the NEC code book it’s fine to use oversized wire it just can’t be undersized
Most electricians I know prefer the term "leg" to phase. It's just a single phase service.
So if I push the walk button 35 times it won't let me cross any faster? lol jk Great videos, love all the interesting info 🐾🐾
What do your working hours look like? Most videos seem to be in the dark.
Great channel, you should do a big traffic Q&A. First question: it's nice to know that the ped crossing button does something most of the time, if you keep pressing the button, does it prolong or speed up the process at all?
Epic
How do the pedestrian count down timers know how long to count down for? Do they get the value from the controller or do you have to program them separately?
Do Y’All do opticon or pre-empt tech for the emergency departments? Also, what about rail interconnects for crossings?

Can you tell us about the conflict monitor - what it does and how it works?
What is a “Type 3” (or is it “Type D”?) traffic signal? What makes it different from the other types?
Can you discuss all the principals& purpose and the reasons behind the conflict monitor that would probably make an interesting discussion

Any 332 cabinet content?
Just a question how come they don't put concrete ballards around the signal cabinets to protect it
