Your video was a delightful surprise! I wasn't expecting to be so captivated by the content, but you managed to keep me engaged from start to finish. Your genuine and relatable approach makes the video so enjoyable to watch. I appreciate how you tackled the topic with a fresh perspective, shedding new light on familiar concepts. You've gained a new subscriber, and I'm excited to explore more of your content!
There was once a company called General Railway Signal (GRS) in Rochester NY that designed & built railroad signaling & safety equipment for more than eight decades. Back in the 1960's, GRS had a shortlived excursion into highway traffic control systems. Upon quitting the business in 1969, the company donated nearly $50K of inventory to the electronic technology programs of the school system I attended. We students were able to get some of the systems operational in the lab but eventually they were scavenged for components. While getting rid of stuff taking up space in my barn last week, I discovered several proprietary high current relays, less sockets, some circuit boards, a bunch of odd low voltage indicator lamps & a sonic lane detection transducer (actually a massive aluminum cased JBL tweeter) that came out of that GRS equipment. GRS traffic control lives on...
Dates on Equipment displayed 7/25/24 so Thanks for the Lightning Quick Post. Thanks for showing us everything Worked. Keep up the Strong 💪 Efforts. Thanks!👍
Do you have a video where you explain some of the terminology you use like what overlap is? I love seeing videos like this because it feeds my curiosity.
I have learned that most of the light controllers in my area are not set for dynamic controls. Even though I can see there are sensors, the timing almost never changes. :) I have put in a call to our local office to have my nearest intersection evaluated as right now, even with little to no crossing traffic, you will be sitting at a left turn red light for 10 minutes. :P Good stuff!
Just found your channel and have been watching for a few weeks. Went back to the beginning looking for a vid explaining the basics, but didn’t find one. Could you do a video explaining the basics, terms, what each piece of equipment does, etc? What’s an overlap? Keep up the awesome work!
A very clear example of how to transfer data and upgrade firmware and how to covert from flashing to protect left turn. One thing that might help we converted from wire ties to Velcro wire ties. That makes wire changes quick and easy.
What does a flashing green arrow indicate? It’s not in the US MUTCD-it is actually specifically prohibited. “A flashing green signal indication has no meaning and shall not be used.” A steady green is a protected movement. A flashing yellow is a permissible movement at own risk. Steady yellow is GUN IT! or prepare to stop. A flashing red arrow is a permissible turn movement after stopping. Steady red is stop and wait.
@@macmedic892 here in the middle of Canada, protected left is a flashing green arrow. Amber arrow is for the end of the protected cycle, and a regular red light is used to indicate a stopped turn lane. Here a solid green on the turn light is used to indicate that it is permitted to turn left when clear.
@@jdshaw83 yeah, but blinking left arrow means "go left and don't worry but also don't hit anything" We also have a blinking U-Turn arrow :) I was in Saskatoon once and they have an Amber & Red cycle before green, like a prepare to start light. Regional differences are fascinating.
Mr.TLD, have you ever considered wearing a go pro headgear like (Mike The Scavenger) to keep both your hands free, he also has a light on his head along with the camera for at night recording?Thank you for your video's, very interesting....
Is it correct that the conflict monitor is only checking the voltages on the low voltage connections - so if you accidentally moved the wrong wires on the screw terminals, you could illuminate the wrong lamps in the signal heads?
Another great video and I know who you sound like now Mr Science although you are better you got a family and a Jeep and you're a lot more fun. Keep up the great work I enjoy every video
When you mention specific terms, like "protected left turn," in the videos, can you give a quick explanation of what that means and/or cause and effect of changing it to protected left turn?
Is there not a way to just change the FYA signal to protected only just in the controller? Where I’m from in GA, they can just change it dynamically. I understand you can remove the overlap, but does the wiring have to be done to remove the FYA?
Do you actually need to take the sign down? Just because the signal *can* display that, doesn't mean it *will* so it would effectively be a free no-op without having to worry about the signs.
I am so amazed that you did this. There is one traffic signal area. That gets program from Flashing Yellow Arrow. To become like a left turn arrow. I think it is good and be more safe.
Traffic Light Doctor is Right, mostly 120Vac in the US and 240vac in other countries. To add, some of the newer traffic cabinets under the ATC Standard can be 48VDC with LED Signal Heads.
Seeing "should of" written with an actual pen makes me unreasonably annoyed, lol. It's bad enough to see it in a UA-cam comment or something, but actually written down? Oof.
Feels illegal to being early. 😂
Agreed

Learning something new about traffic signals everyday. Thank you traffic light doctor 💯💯💯💯
Have the police ever pulled you over when you're doing detection check, because the officer didn't get a memo regarding the requested changes?
Do you keep a paper log book in the cabinet so another technician would know that you changed those wires over on the terminal blocks?

Do the electronics in the cabinets ever get too hot? Is there a method to cool the cabinet interior?
Huh, the green turn arrows don't blink in your region. Fascinating.

@@T1CThat’s….confusing, because a solid round green means go, yes?

Where did the Traffic Signal Doctor go to Traffic Signal Medical School?
What is different between firmware version? Is it extra menu options or is it fixing errors in the software?
@@andrew2004sydney both!
Do you have to have the intersection flashing while updating the firmware & these configs?
The conflict monitor does it automatically but he could also flip the switch ahead of time.
I nicknamed that flashing yellow arrow, the yellow blinking light of death
Why
How did traffic lights work in the pre-computerized age?
It goes to show that you don’t have to be a doctor, lawyer, or scientist to have a complicated and vitally important job. Thank you!
Do you actually need to take the sign down? Just because the signal *can* display that, doesn't mean it *will* so it would effectively be a free no-op without having to worry about the signs.
I never knew I wanted to know this.. GG UA-cam algorithm…
I'm shocked it's not simply a software configuration to eliminate the flashing yellow on a temporary basis.
My question is how many botch jobs do you encounter when you go to a cabinet at an intersection?
I am so amazed that you did this. There is one traffic signal area. That gets program from Flashing Yellow Arrow. To become like a left turn arrow. I think it is good and be more safe.
Do the traffic lights run on low voltage or are the 120v? Just curious. Thx for the great videos!
120v and some other countries use 240v to supply power to the heads!

@@Yotanido not enough room on there for have! Thanks for commenting!
@@Trafficlightdoctor "Should've" would've definitely fit :P
Jesus those systems are so unnecessarily complicated. This could entirely be run from a Raspberry Pi, managed from a central office.
