Street Smarts Traffic is a platform I created to share traffic signal knowledge. Follow along with me in the trenches as I fix traffic malfunctions, program traffic devices & create traffic solutions.
Now in my 3rd decade in the traffic signal industry serving in 2 DOT's (County & State) and a 5 yr stint with a traffic signal distribution company helping customers in field service, this is what I realized:
There's a need---
-Traffic newbies need a foundation
-Older generation of traffic signal techs are retiring (taking knowledge with them).
-Many are overwhelmed with advancement in traffic technology
-Agency directors nominate their Public Works personnel (who are untrained) to maintain the city's most liability prone assets (you take care of everything else!)
-Since many maintainers do not know how to diagnose a signal problem properly, complaints go wayside.
Sound familiar?

Like your video!! I found other than direct lightning strikes or strikes that like to reverse right up the low resistance path of earth grounding systems -- lightning is notorious for destroying any electronic equipment that utilizes large loops of wire from either intense B fields or EMF coupling, regardless of TVR protection or GDTs. For your ground inductive loops do they interface directly or do they first go through an isolation transformer to help protect them?
glad you replaced the batteries.. they might still be good for aotomotive use if it holds a charge but to be depended on they just cant be trusted, i love the way you troubleshoot, reminds me of how i do things
Good to hear the approval! Yeah, wouldn't look to good on my part is if i said it was good to go after just the UPS unit swap out and then they go to kill power and the signal goes dark 😬 Thanks for commenting and the kind words!
Confusing thumbnail
If you think thats confusing, wait to you see some of my upcoming ones! lol
Wow. Nobody but you guys appreciate how complex these systems are. And the amount of training and knowledge that you have reminds me of the airbus technician at the airport. I think the Airbus may not be as complicated.
😬🤷♂
We use a fuck ton of 1 and 2U UPS Systems, some are always running from massive battery backups some are almost always idle, and some are just there to look pritty. Our number 1 failure mode, is a fucked cell in a battery - Easy repair. Number 2 failure mode is output capacitor failure on the filter network. Again Easy Repair and finally the most common that aint the above, the transformer cores crack due to excessive heat (no something we have in the DC but the outside units fail like this more often that not. All 3 can be repaired in house, capacitor replacement is a 2 min solder job, same for transformers, and batterys well youve seen how that goes. That failed unit is screaming blown cap.
Scratch that just noticed there ENERSYS UPS's systems, and there banned in all the buildings i have worked in or will work in the future, 33% failure rates in the first year.
Thanks for providing all that info! I have a pallet of recent UPS units I pulled out of these cabinets on inspections. I HATE to throw them away. I would love to break them open and do just a component repair. Of course, the UPS manufacturer said I could send it in for repair....the shipping charge alone will be more than the repairs. LOL. Maybe I should find out the most common failed parts and cross reference their specs. Maybe I could find some replacement parts online somewhere. Its worth a try to get more years of life out of these units instead of throwing them into the trash! Thanks for your insight. Much appreciated!
A few years ago we had a nearby hour from lightning at our church. It was quite amazing what equipment got taken out. I think most was though low voltage stuff like network hardware. But who knows. Digital mixer, camera, network switch, distro amp network port on a PC, video card, monitor. You get the ideas.
It adds up fast don't it?! Lightning = Bad!!
What did that cost to fix in parts, not counting labor?
Lets see...controller = $5000, load switch = $25, BIU = $300, radio + POE (both sent in for repair) = $500 (I think), LED indication ($75/each), detector card = $200. Didn't replace the detector card rack but if I did, that would have been costly as well. Adds up fast!! Thanks for commenting
Where does y'all fried equipment end up trying to find a good place for junk electronics for my gold recovery
If its warrantied still, it gets sent in for repair. If not, then it end up in the recylce bin. Great question!
You don't have to wait for the tubes to warm up.
What I have noticed while working private security during the wee hours 2 to 3 to 4 AM, many intersections will stay green all the time for the primary thoroughfare unless a car appears on the minor road which would be normal. HOWEVER, after a hard rain, the lights cycle just they do at high noon! Since most every intersection is now controlled by lane cameras rather than loops buried in the roadway, I’m wondering what is causing this❓ Thanks for your outstanding informative videos👍👍
I cannot say for sure this is the problem, but I've dealt with a similiar issue on a project recently. Many cameras are power over ethernet. The ethernet cable that is plugged into the camera up on the mastarm has the best chance of getting moisture in the connector. Everytime it rained, some of our intersections would cycle as you describe. Then after awhile, they would start working fine. We found that the contractor forgot to put dielectric grease in the connector up there. THis would prevent moisture in the connector. When a camera is affected like this, the camera processor sends constant vehicle calls for that direction to the signal controller, thus the cycling. After the connector dried up, it would work fine again. The contractor had to come back and go thru 18 intersections and install dielectric grease in every camera. Quite alot of extra work they could have avoided if they did it correct the first time. Thanks for the nice comment!
its like swapping relays in your car trying to figure something electrical out when you swapped them blocks around lol or ignition coils chasing a misfire lol btw i would feel like god if i was you controlling who goes next lol
Great analogy. And yes! Its fun when I'm working at a signal and someone rolls down their window and yells out "Hey, give me a green light!" Then I point at the signal as they're still looking at me and they turn to see it's green for them. The people love me for that. "I will win the crowd, I will give them something they never seen before" (Gladiator reference) LOL!!!
Wow, whats the best way to get into the field? This is really fascinating
I work in industrial automation, I’m jealous that all the modules just pull out😂
What?! No hot swappable modules?! Time for a redesign! lol
Pretty Interesting. I work on Commercial HVACR and teach apprentices. It’s a pretty impressive control system for a normal traffic light. I like how the components are modular and can be easily replaced. What Voltage is used in the cabinets and to the lights? I’m surprised we have not come up with better lighting protection for the cabinets. Thanks for the Videos.
Hey welcome and thanks for the comments! The engineers at least thought about us operational guys when they designed it. Yes, easy hot swappable. In most cabinets, you have 12V, 24VDC & 120VAC. Load switches take the logic from the traffic signal controller and converts it to 120VAC to be sent to the traffic signal indications. There's some surge protection in the cabinet, but nothing that will withstand a lightning strike. Thanks again!
Wow, has anyone ever done any maintenance on the battery backup? That fan is just clogged. I've seen worse, but this is easy to maintain. No surprise it's not working.
I know, right?!. Been a bit since this cabinet has been visited...I'm getting a lashing about this on the comments 😬
Electrical tape screwdriver...
I know, I know...Poor mans version of an insulated one lol!

I know, right?!. Been a bit since this cabinet has been visited...I'm getting a lashing about this on the comments 😬
Pre-wired batteries... where have I heard that before I forget, but it sure beats having to jerry rig a bunch of crappy 14 year old shredded cable like I had to try and do for my NiMH R/C batteries that are shot
Isn't that the worst?! lol
This fire is going to be burning for quite some time.
We've been slowly upgrading cabinets/signals on projects when $ is allocated. So hopefully the burning will be for not much longer lol
Way too complicated for its job
I keep getting told there's an easier, more slimmed down way to do it. I'm just waiting for someone to show me how! LOL (and the same realibility and error checking as well)
Same thing here (71) now, looking at improving systems, a good pastime
I have a little ways to go to get there but I already find it fun and a good pastime as well! Thanks for commenting!
1:44 You need to set up a charge station. One string should be sitting there at float voltage ready to roll. Really a couple of strings should be ready to roll. I say this with a few decades in telecom DC power plants. Just takes one relay rack bolted down and some shelves and wires and the charger. Why are you pulling cables to check battery voltage? There are test points for a reason. Every time a cable is pulled is a potential outage. PMI and best practices.
Thanks for your insight. I've been thinking for awhile now we need to set something like that up. We have a pallet of new batteries that have been sitting for awhile. Great idea to keep those 'on the ready' when needed. Curious to hear about the relay rack design your using...
The homemade insulated screwdriver....
I was waiting for someone to point that out! LOL
It's interesting how most of those boards are hot swappable, so you don't have to switch the whole thing off to replace parts. But it makes sense in a mission-critical system such as a traffic light.
Yes, thank goodness the design engineers made it easy for us operational guys to do our work. Comments left here also point to other industries that use similiar designs. Thanks for your comment!
I'm now convinced that a backup system should be required on all traffic light systems in the US.
You find out which drivers know to treat a signal as an all stop sign signal when signals go dark. I see about 2 out of10 that blow right through it almost causing an accident. It definitely becomes a dangerous situation without power.
@streetsmartstraffic Where I'm at it's the exact opposite. I treat them like I'm supposed to, but I've had other people honking at me and give me the finger and all that jazz because I'm doing what I'm supposed to. Very rarely do I see anyone treat them properly. Even a basic 4 way stop people just blow right through.
@@SOU6900 Ok i have to ask...where abouts are you located? I'm sorta doing a pole on how bad drivers are getting...

You can't outrun the spicy finger of mother nature it's like water it will win 😊
Agreed!
Imagine you're in the middle of swapping boards on a traffic light when you hear a crash...
I've had it happen many times!
The swapping modules to test to isolate the issue to the components... I wonder if any of them show scorch marks from the energy. Gas lightning arrestors would work, but likely it's cheaper to just replace the components. I agree with the Right To Repair comment... as the only ones who win with it being prevented is the company selling the item, as they get to extort money under the guise of "Intellectual Property"
Yes sir! I guess I'm creating a product I want to be the only one to 'fix the issue'. Whether billing you for the repair of selling you the new product. Capitalism baby!
Sounds like the wire is bad somewhere underground. We usually pull a new home run for the affected phases. Using a spare wire is a temporary fix at my job
We were on our last leg on this one. So we went with using the spare wire. I'm sure we will be pulling in a new cable if we have anymore issues. What industry are you in?
@@streetsmartstraffic I am an electrical mechanic. I work on traffic signals for NJDOT. We will use the spare when we can, but we don't seem to get that lucky anymore. Usually multiple wires are exposed and shorting out or are burning onto another wire.
@@matthewjacobs1164 Thats cool. So you must do it all! Not so much on the construction side for me...although I will help out. Yeah, I felt lucky that we were able to get it going again with our spare wire. I shot that video like last year I think. Still running!
Its ok - then it just turns into a no-way-stop.
Most times!
alpha company seems to be a bunch of morons. warranty void stickers dont mean anything legally
How do all the electronic devices in that cabinet not overheat with the summer sun beaming on the metal cabinet?
We have thermostat controlled cabinet fans. The fans kick on and blow the heat out of vents under the top flange of the cabinet. The trick is to have the thermostats set correctly! Great question
The good ol turn-off turn-on move.
Oh man! You knew that move too?? LOL
Why don't all traffic lights have battery backup?
Great question! Usually it just comes down to cost. If a small municapility is installing a traffic signal, they usually just want to get out with the cheapest cost. Their coffers are not usually as full as say a State agency.
No Power from the Mains.. Either increase the operational Voltage to overcome the air gap, or... Plug it in 🙂
Yes sir! Thanks for the comment!
I appreciate the lack of editing. Sometimes I scratch my head wondering why something isn’t working only to notice that the equipment isn’t plugged in😂 I know there’s a temptation to edit out little boo-boos like that. I appreciate your keeping it real👍👍 These are teachable moments for traffic signal techs learning the trade. Great job.
I try to keep it real! As i talk about in other videos, I keep the camera rolling to show mistakes I make so other maintainers (and as I have found out--many signal hobbyiest) don't make the same mistaks. I balance between length of video (get to the point!) --vs showing small things that may be missed during troubleshooting & repairs. Thanks again!
That is why IT does as that first... so many times it is the issue...
Nice to see DOT being as proactive with their batteries as the cable company. (at least you're replacing them once spotted.) Also, at 2V for a 4S string... those batteries are now trash. (there's no telling how long they've been like that. not that we were shown how old they were to begin with.)
I answered this same question in another comment here...so sorry for the redundcy. This video was shot not long after I came to this DOT. They were down a tech for over 2 years and many things went wayward. One of initiatives we pushed 1st was to update all the batteries. (Probably sat dormant for years). Anyway, as we were replacing batteries, we found many dead BB units. They're not cheap so we had to budget over time to start replacing them. This was one of them... Thanks for commenting!
You mean more pro-active! Cable company just says "hey customers, if utility goes out we can't do shit about it, don't call us not our problem". They actually went and fixed this traffic light backup!
@@matthewmiller6068 Well we tried! Once we get all signals on to our network to monitor (over time this will happen) we can set up alarms to notify us when batteries are getting low. In the meantime, we started a 4 year plan to check batteries for replacement. Thanks for the comment!
Lol the clogged fan killed it
This was a really dirty cabinet! I'll get to it! lol
Too bad they don’t make a device that you install to the cabinets that will absorb the lightning and divert it away so the contents don’t get fried. I bet that stuff is expensive
We have some smaller power suppression for the incoming utility power lines. But as you have probably read in some of the comments, sound like there's some stuff out there if you want to really spend the $$$! Thanks for commenting
1 second ago No views No comments No likes I'm first
WHAT?! Thanks for filling the void!! lol
Seams like there should be maintenance done on the batteries on a regular basis, thats what companies do that have critical equipment. Not sure the purpose of a battery back up if there is no checking or maintenance done.
Unfortunately, AT&T is guilty of the EXACT same thing. Years ago the company treated battery backup systems as a serious, important function to provide total reliability to the customer. Not any more. Even when the company was regularly having pallets of batteries shipped to outside facilities warehouses, they would not schedule outside plant technicians to do battery replacement. Batteries simply sat in the warehouse. SERVICE is no longer a priority❗️

That's really interesting; Worked on some huge industrial furnaces and they got battery back ups on conveyors should everything fail.
That's cool! Interesting to hear about other industries that use BBU for criticaly type applications. Thanks for commenting!
@@streetsmartstraffic It's to ensure the machine won't be damaged during a power outage in my situation; For both of us machines need to provide services even if half rooted.
@@TradieTrev Agreed!
I didn’t know traffic lights had battery power backup. I don’t think any of the traffic lights in my town have it. If there’s a storm and the power gets knocked out, the traffic lights in the area are all dead, and you treat the intersection as 4 way stop.
"Light, sign, line"... but no one remembers that from driver's ed. (i.e. no one cares about the law.)
Not all intersections have them. Some municapilities don't want to spend the money as they'll just use generators or stop signs during outages. We get them in our spec on every new or upgraded cabinet design. You'll usually see them on higher speed corridors due to the increased danger posed by outages at those critical intersections... Thanks for commenting!
The fan of that backup unit looked really clogged! Why don’t use LiFePo4 batteries as replacement instead of Pb? Tnx for the vids!
Yes as I answered a few of the other comments, this was a dirty cabinet. I don't really have an answer for battery question I had to look up a little about them.. It said the drawbacks are: higher cost, slower charging speed, lower discharge rate, and limited temperature range are some of the drawbacks of using LiFePO4 batteries. Maybe their not compatible or optimable with the system? I'm not sure... You're welcome and Thanks for commenting!
@0:25 - no, you mean motoring public. Pedestrians, and especially cyclists completely ignore traffic lights.

Too late! His boss let him go! lol
If the batteries sat for any length of time at such a low voltage, theyd be pooched anyway even if you did recharge them. So glad you decided to replace them!
Great point! I just hate throwing out anything and if there's any chance of life to it, I want to still use it. In this case however, I'm glad I replaced them too! thanks for commenting!
@@streetsmartstraffic I've had alot of success reconditioning lead acid batteries on a decent charger, especially the sort with the caps as you can rewater them... But only managed to get about 50% capacity back. Even with half the capacity, probably not bad to keep on the truck for an "up shit creek" scenario when you don't have any in the shop or can't get to them.
@@alex13902 Excellent point. I brought those back to the shop bought I think they ended up on the pallet for return. 😬
@@streetsmartstraffic Likewise but whenever I've encountered an issue with the charger or even if it was only one battery that was faulty, both batteries would be replaced as preventative maintenance in the fire alarm system. Same for the emergency lighting. Better safe than sorry.
@@dang48 ah, good to hear...and agreed! Thanks for your input!
I can see why that battery backup went RIP.... That fan.... must have been a pretty harsh heat stroke before that battery backup threw in the towel and said "bye bye". Might be good to invest in a battery powered vacuum cleaner (like milwaukee M18 VC2), so you could do some "preventative cleaning" inside those closets, especially around fans and ventilation holes.
You're right Sebastian! Many of these cabinets have either been upgraded or are finally get cleaned up. As you know, alot of stuff already takes a beating from heat--they don't need all the dirt as well! I've since purchased a large wetvac to do some major cleaning in these cabinets. Good observation!
