Excellent video. The synchronization of construction changeover from the old improvements to the new construction is always an exciting process. Maintaining a safe environment for the workers as well as the impatient public is a nerve wracking experience. Well done with having the spare equipment when the inevitable malfunctions occur. I love watching your videos as a retired civil engineer/project manager. I worked on many traffic signal designs/installations/modifications. In California, the full 8 phase mast arm traffic signals are well north of your $200k cost.
As someone in the industry i was also surprised at the $200k cost when currently the material alone for an intersection is about that. Hell the mast arms alone can easily be 30k+
The IES Lighting Handbook and the 2014 National Electrical Code, Article 100 (originally the 2004 NEC), define a luminaire as, “a complete lighting unit consisting of a lamp or lamps together with the parts designed to distribute the light, to position and protect the lamps, and to connect the lamps to the power supply.”
Sure am glad i am retired from that stuff. Worked for a city for 24 years mostly doing signals. Very interesting work altho we had nearly all Type 170 controllers. Very little NEMA stuff, only some of what we maintained for the county. Been out of it now for over 20 years and certainly see a lot of new equipment and periferals that keep coming out. We had cameras but no radar detectors and we were still using older 170 controllers and Bitrans software. Keep up the good work.
New intersection level luminaries look great. Never liked using high mast for intersection lighting. Mast arms look cleaner than spans any day of the week. Great work
With those new stop lines and all, and the new lights, it looks MUCH cleaner than before! Wonderful work! Thanks for filming your POV, it was very cool to see!
A lot more labor erecting them and burying all the cables to each foundation. The span wire is all above ground except from the controller to the nearest pole.
Thats because it is. You are looking at how government officials launder their money. Give their friends insanely overpriced contracts and then they donate it back to them.
"Some people might have questions on why we have two Click 650s in here..." Respectfully sir, I don't even know what is a Click 650. If you told me you needed 10 of them, I would nod my head and simply agree with you. Fascinating stuff though, but I dont have the faintest clue of what I'm looking at!

The controller logic needs to get smarter in using advance detection to coordinate smooth flow of traffic and minimizing wait times. So often I see these modern intersections cause more delay than a simple timer based system!
Is there a switch inside the panel to make all the light heads red? like when the wires came down? Also is there a function to freeze the light at a certain phase? (Like during a large event where you want to freeze the left turn arrow at green phase manually to let all the cars out?) BTW I enjoy your videos.
There is a Stop time Switch inside the cabinet. When that switch is flipped the controller timing is frozen. During the 1-2 second of all red interval he flipped the stop time switch.
Scratching my head why my previous comment was deleted... Anyway, I worked as a construction inspector for a state DOT many years ago, and we used 170 controllers exclusively. They were always fitted with a STOP TIME switch, and I found that to be very handy on occasion. I noticed a similar switch inside the cabinet here, and wish NEMA controllers all had them as standard. Just my opinion. Subscribed.
I admit I had never given thought about the skilled people who install, maintain, and repair all the traffic signals. Thank you for your work and videos. How does one study and get a job doing this? Electrician trades?
My city just recently started doing the flashing yellow arrow now and they’re replacing the mast arms that aren’t even 15 years old. Some intersections they replace the dog house with a flashing yellow arrow but most of 5 year old traffic lights getting replaced here.
@@jovetj but it’s some mast arms style that I loved that got taken down for a boring mast arm. Ik it’s weird but it’s like damn they aren’t even 20 years old ☠️☠️☠️
@@Fade2005 Oh, if you're talking about the cantilever designs themselves, that I don't know. I thought you were just talking about the implementation of the Flashing Amber Arrows.
I saw on a 2007 street view this intersection had yellow signal heads so the old signals that you guys replaced in this video were installed between 2007 and 2011
Cities typically only maintain their existing equipment. I.E. changing lights/LEDs. Major installations/modification work is by traffic signal construction companies under a construction contract with the City/County/State DOT.
I work as Traffic Control in the PNW, this would’ve been a full shut down to one lane and full flagger set on each road. Really interesting to see how these key infrastructure jobs are done across the country!
In my city, pretty much all of the lights are masts. They are probably even more expensive since they are mostly arrows instead of the typical round light. Depending on the intersection, they'll have anywhere from 4 to 7 different lights. They are hung horizontally rather than vertically. Another huge difference is that instead of having one set of light for each lane, there's only one set of lights for all of the lanes.
It's interesting to see how people do it. Over where I am the contractors don't use a grinder to cut the old spans down. They just take off all the old signals and cut the old span down with bolt cutters. Also are you sure that this signal was only worth around $200K? I once saw the bids from MDOT were public and the bid for a signal replacement in my area was $517K for a new Box-Span intersection with backplates, 40FT strain poles (6 bolt) and new sidewalk ramps.
Illinois (IDOT) started using radar detection instead of loops for side streets of main roads at intersections. There ended up being a lot of issues with them not detecting stopped cars, so they swapped to video instead for side streets. Using only radar for an entire intersection is a foreign concept to me. Are you experiencing issues of non-detection with stopped cars that IDOT was having?
I always wonder how they put up and take down the string light (aka construction mode lights) as well how the signals are "cut over" when switching them over. The radar system is great as it can "see" the traffic as oppose to the induction loops - problem is does the system work in the cold and snow of northern states?
I'm guessing Siemens stopped putting their logo on the newer m60 systems for a reason and did the Yunex spinoff instead lol. Seems like Siemens is working better here.
How long should the mast arms last? I live in central FL and they seem to replace mast arm installations after 20 or 30 years of service. I would think they should last a lot longer.
Poles that can take a car, leds the size of your head, 2-3 wires per led head (that's 9 wires for a standard 3-head red-yellow-green setup), 2-4 3" underground conduits between each poll (minimum 6 long conduits total), manholes at each corner, and controller cabinets that are $10,000 to $20,000. Lighting wiring is usually run in its own 2" conduits. This is the standard in MN, at least.
Pros: Mast (cantilever) arms look a lot nicer. It's easier to attach things to them (e.g. signs, detection systems, etc.). They usually handle extreme wind better and don't sag over time. They have a smaller and tidier footprint. It's easier to pull/replace cabling should it be necessary. Cons: Mast (cantilever) arms are more expensive. There is much more labor to install them, especially preparing the foundations and all the underground wiring. They're more expensive and take more time to repair if they are damaged.
The town I lived at in Florida had two major expenses that took %90 of the Budget. The one traffic light, payment to the attorney the good ol boy network hired. He's the attorney for Enron who was disbarred, but still allowed to practice in the corrupt swamp called Florida.
Question: I have been watching you for a while, But trucks with green flashing beacons? what is that all about? Here in the UK, only doctors on call can have green beacons (Even then you don't see many about). I have seen you with lights in "flash" but what is that for/what does it mean, Like I said, I am here in the UK and we don't have that either. Thanks😃
Green is getting pretty common these days. Our highway trucks have yellow and green beacons. If there is a problem with the controller or they are working on it, it goes into flash so there is still some form of traffic control.
Allowable colors on vehicles vary by state. For example in NY Fire and Police can only run red forward facing, while in Mass. fire runs red and white and police run blue and white. Utility/construction also varies by state, most common is amber.
Flashing red lights is an all four way stop controlled intersection. Stop and proceed with caution. Not too bad for single lane roads. It is more interesting when you have three lanes in each direction with left turn lanes too.
@@mtmmac1 -- In my state, only law enforcement are supposed to have blue (but I see blue on some fire trucks and some Uber drivers as well, so not well enforced, I guess). Red should only be on emergency vehicles and school buses, but they count tow trucks as emergency vehicles if they are in the police rotation for police calls. Anyone may display amber if they believe their vehicle might be a hazard for others, and it defined in the law that it is the driver's discretion -- nobody may second-guess that decision. Green is not defined in the law here, so we see it on fire chief vehicles, security company vehicles, the van owned by a local credit union, and my friend Tyler, who simply likes it, I think.
@@jovetj right… none of that should cost $200k. the only reason it costs $200k is because it’s paid for with taxpayer dollars and all these companies start seeing dollar signs the second government contracts start getting handed out.

@@timr86868 If you feel like the taxpayer is being fleeced, then start your own company and offer those products and services to the taxpayer's dime cheaper.
Do you all refurbish / reuse the old signals? Do they just "trash" them? Are they sold off? I've always wondered what happens to most of them. I bought a signal years ago from a guy who lived next to an intersection up in Maryland - he told me the crew was just doing to trash them, so he asked to have the old signals, and the crew just handed them over. His story was believable because the intersection in front of his house had all new signals and the crew was long gone... Years later I witnessed crews in Florida just cut the wire - dropping signals and wire straight to the ground (causing damage to the old signals) when turning on a new intersection.
Redundancy is needed. By the time your raspberry pi system has all of its redundancies and fail-safes in place required for a traffic light, you might as well just get the specialized controller.
@@Trafficlightdoctor I'm a pretty fair medic and firefighter, & today I learned about the breathtaking cost of traffic signals, but I don't know anything about the costs of these things. I do have to wonder about safety and if there's any increase or decrease in one over the other.
It's kinda weird to see the south installing permanent light posts. I know the south hates taxes so much that they don't want to fund permanent light fixtures, that they prefer the ugly rope fixtures. This looks strange! Well done! 😂😂
It seems like the equipment used here is absolute overkill for some circuitry that reads sensors, runs the info through some basic logic and changes which lightbulbs light up.

Fun fact, “luminaire” isn’t in MS Word’s dictionary, so a lot of user manuals talk about how to “install your new luminary”
The IES Lighting Handbook and the 2014 National Electrical Code, Article 100 (originally the 2004 NEC), define a luminaire as, “a complete lighting unit consisting of a lamp or lamps together with the parts designed to distribute the light, to position and protect the lamps, and to connect the lamps to the power supply.”
Extremely interesting to see a traffic signal conversion at a large intersection👍👍Thanks for bringing us along 😊
A detailed series on the installation of a new intersection would be great! Poles, light heads, sensors, cable runs, cabinet, lines, etc.

Because they are trashy. 😁

Industrial equipment have a very high tolerance levels. That and the cost of maintenance and warranty along with other stuff.
Poles that can take a car, leds the size of your head, 2-3 wires per led head (that's 9 wires for a standard 3-head red-yellow-green setup), 2-4 3" underground conduits between each poll (minimum 6 long conduits total), manholes at each corner, and controller cabinets that are $10,000 to $20,000. Lighting wiring is usually run in its own 2" conduits. This is the standard in MN, at least.
surprised you guys run green flashing lights on the trucks . my state is amber, green is security only although most security runs amber
Whats the advantage of a $200,000 dollar light compared to $60,000 one? (Besides a 233% increase in price)

Yo I want a old traffic light I have been trying to get one for ever but to much money can I get a old one
in my city they change all the traffic lights to flash at about 11:30pm, is that normal?
Yes.
So what do the new lights do that the old one's didn't?
Detect traffic better and adjust traffic flow better. And not get blown over in the wind. Hopefully.
😰 _the fact that a traffic light costs as much as a moderately mediocre car_
And people think roundabouts are cheaper
@@Trafficlightdoctor I'm a pretty fair medic and firefighter, & today I learned about the breathtaking cost of traffic signals, but I don't know anything about the costs of these things. I do have to wonder about safety and if there's any increase or decrease in one over the other.
@@Trafficlightdoctorwait aren't they?
@@_monti142 Sometimes they can be. It depends on many factors, mainly he footprint of the proposed roundabout.
It's kinda weird to see the south installing permanent light posts. I know the south hates taxes so much that they don't want to fund permanent light fixtures, that they prefer the ugly rope fixtures. This looks strange! Well done! 😂😂
We want longer videos
I’m trying! 😁
@@Trafficlightdoctor yaaay
Hell yeah
Build back better. Thanks, Joe!
It seems like the equipment used here is absolute overkill for some circuitry that reads sensors, runs the info through some basic logic and changes which lightbulbs light up.
Well, not exactly. One, it just has to work. Two, malfunctions can cost lives. Three, it just has to work.
I am autistic and I could work with you if there weren't so many distracting flashing lights.
