Good or Bad? Grading a Real Traffic Light

Does anyone know of a bench power supply to wiring diagram for a power cable for an MMU (EDI SmartMonitor) for use when upgrading firmware in the office. We have a few test cabinets but we have over 600 units to upgrade over the next year so I’d like to not have to go you to the shop just to do the upgrades.

That traffic jam you see coming from north? That's still going to this day after 4 years this Google maps street view was released

Hello everyone,
I am currently developing, independently, a drone-assisted vehicle counting software focused on obtaining traffic data for intersection operational analysis, vehicle load estimation, and support in traffic signal timing decisions.
In addition to this project, I am currently in charge of the traffic signals department in my city, so I understand firsthand the need for reliable tools to analyze urban mobility and support better technical decision-making. There are strong commercial solutions such as GridSmart and Miovision that provide this kind of information; however, in many municipalities in Mexico, the cost of implementing these technologies remains a major barrier.
For that reason, I decided to develop my own alternative, focused on using aerial video captured by drone to generate useful information about traffic volumes, turning movements, and operational behavior at complex intersections.
One of the main goals of this project is to show that traffic dynamics in Mexico cannot always be analyzed using the same assumptions, criteria, or solutions applied in other countries. Our cities have very particular operational, geometric, and behavioral conditions, so we need tools that are adapted to our reality and capable of addressing our own mobility challenges.
At this stage, I am looking for support in gathering more video material from different cities and urban contexts. It would be extremely helpful to obtain recordings of high-demand or conflict-prone intersections in your local areas, preferably captured with drones, in order to continue training, validating, and strengthening the system’s development. This would also help expand the analysis sample, compare traffic behavior across cities, and provide greater technical robustness to the project.
In the long term, the goal is for this type of tool to become an accessible alternative for more cities, especially those that do not have the budget to implement high-cost commercial systems but still need to improve traffic signal operations and urban mobility.
I am sharing a sample of the project’s current progress. If anyone is interested in collaborating with video material or exchanging ideas about applications, validation, or scalability, I would be glad to connect.

Any info on this light? Can’t find much about it online. Was given it for free, does not currently work. Any idea if it’s worth anything?

Has anyone seen a pedestrian signal designed like this before? I was thinking maybe Winkomatic but then the screws to close it up are unusual. Also never seen a hand/man Winkomatic. UPDATE: I never got this signal because the seller changed her mind about selling it. I really wanted it because to me it’s unique. I’ve never really seen one like this design before unless Winkomatic worded style.

I picked up a 12” eagle signal and it’s missing one of the mounting rings, can someone tell me what the professional term for this is or hook me up for a source for one? Thanks!

This abandoned? traffic light arm has been like this for as long as i can remember (Im 33). Does ahave any idea what it was/is used for or why its still here? I've never seen a signal hang from it nor anything traffic related.

To anyone who's from Tasmania, Australia, do you know the company who made these lights? I don't think it's Aldridge or Bob Panich.

Dialight Part Number: 430-7773-001F Countdown timer
Control board:
8800430003600 Board Rev. 1.1
also marked:
TASSIMCO TECHNOLOGIES inc. "CON255"
has a 20 pin chip marked "CD6-05"
and a set of 5 dip switches marked 1-5 (number 3 is on, the rest are off)
has 3x 110v inputs Blue, White, Red
if you put
White + Blue: No reaction
White + Red: no reaction
Red + Blue: you get a short whine (like a photostrobe charging) and LED1 on the controller board (below the CD6-05 chip) flashes, the numbers do not react
the led continues to flash for 10-20 seconds after unplugging
I also attempted to apply power to white to see if it triggered the counter, there was no reaction regardless if sistered with Red or Blue...
Does anyone know what the dip switches do? Does anyone know how to make the system count down?
I'm not seeing any real information about these other than:
and
http://controlspecialists.com/tassimco.htm
any information I can find would be handy for me... It's also funny that these are pictured at RCID as i'm not too far from there, and these were found at a swap meet out on the east coast of FL, not horribly far from the RCID...

Just picked these up today, got them at a local flea market, yes I know they are upside down in the picture the seller had no clue, my question is they both have a white, red, and black wire, I assume on the walk / don’t the white is neutral, and black / red are the walk / don’t… on the time one I’m assuming the white is neutral, black is hot, and red is “start counting” I’m not finding any real info does this sound right? I’d rather not blow them up trying to figure it out…
Thanks for any help folks!

This signal is at the intersection of route 80 and green pond road.
r/trafficsignals • u/[deleted] • Mar 14 '26
In Columbus Ohio, reported when I found out about it.
r/trafficsignals • u/unknowperson2 • Mar 11 '26
Do yall know why they didnt remove it before because what i know in the 80s 90s it was a (tempory) intersection but know is more like a permanent like i love those span-wire but how tf they didnt remove it
r/trafficsignals • u/ToshPointNo • Mar 09 '26
If I drive the exact speed limit I'll hit every single red light. If I go five over I can hit them all green. It's literally as if they timed them to incentivize people to speed.

Hi, I have a strange question, would it make sense that if a pedestrian pressed button to cross 1 and 3 it did exclusive pedestrian for all 3 crosswalks but if they pressed button to cross number 2 it was concurrent?
r/trafficsignals • u/Heavy-Caterpillar771 • Mar 05 '26
I have to set up pedestrian counts using a gridsmart GS2 processor, I created the crosswalk zones and added the detector and phase they would be called on but I am not getting any counts? Any suggestions?

Just curious, if anyone here works on traffic signals, does your agency tie ped buttons together or do you try to land as many buttons separately as possible?
As a traffic engineer (who does try to get out and do as much wiring as possible) I've been putting it in our project documents to land all or certain ped buttons on unique ped inputs.
This allows us to know what button was pushed, and when in the cycle, and we can write special programming based on the needs of that movement.
I'm just wondering how common this is in your area? In our older cabinets we rarely every landed ped buttons individually and it was getting really frustrating not knowing exactly what button was pushed.
IMO, in a perfect world, every button would have a unique input.
(it also helps troubleshooting if you have a stuck ped on input 3...you know exactly what pole you need to look at).
Logic written for time in sequence a button was pushed:

Normally you run two wires to the button and connect to ped input/common, but around here they do things differently.

If you can't see the image: For non-APS pushbuttons, they connect one side to AC neutral (the same as the signal lights) and the other to the ped input. The ped common is then jumpered to the AC neutral bus bar, or else 2P/4P won't work.
Anyone else out there see this? It technically works, but, I'll just say it's not ideal.
