Traffic Lights: How They Work!

[rickl]

I had absolutely no idea that traffic signals were this complicated. Good stuff.

Great video! Could you also make some videos of a “traffic controller 101” style where you explain how exactly the cabinets are wired and what all the equipment does? Such as how exactly do conflict monitors work?
You could do these videos at home too while using some software to draw circuits. Just a suggestion

It is interesting seeing these videos of a modern Traffic Lights controller. Since I am 73 years old, I remember seeing old electromechanical based traffic controllers, that had clock motors, camshafts, microswitches and electromechanical relays. I have noticed that these modern traffic lights controllers can be programmed to handle a lot more traffic lights situations than the old style controllers could handle.

Since watching this channel I now look for the control cabinet when I'm at any intersection. Very interesting stuff.

didn't realise i was interested in traffic signals until now. great video thanks

[williammulligan]

Excellent video! I really like how you show the programming and how each of the components interact to make the intersection work

Hey fellow drivers: flashing red == stop

Thanks man I learn something today about traffic light. And who knew traffic cabinets look like the inside of the space shuttle. Stay safe out there, and thanks for sharing with us.

Nice to see an interesting video about life around us. I was a traffic control systems specialist in the UK & still a consultant since retirement. Write contracts, tech specs, programmed our SCOOT control software, ran maintenance contracts etc. what you’re doing was my world for over 35 yrs. worked closely with Plessey, then Siemens, then YUNEX. Great companies!

You mentioned it's a cat5 but crimped with a shielded 8p8c. it might be worth changing to shielded cat6 or higher for better grounding protection. I can see the camera's rj45 port looks shielded for such purposes. I imagine that would be a little tricky to re-run but could make a difference

stop bars -- so i get into the office early around 345am. in hollywood there is a turning lane from sunset blvd to a side street. i noticed if i go too far past a certain spot, the system wont detect me. if i slowly back up, i then see the crosswalk timer start to count down, which lets me know it senses me.

[PipeDoctor]

I always though you need to be on top of the sensor for the light to turn green

I’m glad I found your channel. This work is fascinating and certainly a real asset to society.

Awesome video, love seeing how different systems work. As a hardware and software guy, this makes me smile. 🚦😊

Been using the grease in all outdoor camera and network devices. Seems to do a great job.

I"m here in Montgomery County, Maryland. I"m a 45 year in the trade Master Electrician and I used to get to work with most of the county traffic signal techs. I do know they have been using Econolite controllers for years. Your Yunex controller looks really more friendly.

[SusanMackey-pe]

Nice job explaining and you certainly are very knowledgeable on the equipment

[SneezingEagle]

Not sure why YouTube suggested me this video, but I'm here for it! Fascinating stuff

[gabrielhollar]

I happen to program PLCs and these controllers blow me away. They're so simple but robust and the interchangeability is insane.

[robertholtz]

Respectfully, as a software developer of many decades in another field, these systems seem needlessly complex. Nevertheless, it is neat learning the behind the scenes tech and associated vernacular.Thank you for the great videos.
