Being an old school peace officer, now long since retired, I remember vividly directing traffic. Mostly during peak traffic "rush hours". We'd go to heavily congested intersections. Set the timer controlled traffic light to "caution". Then stand in the middle of the intersection and direct traffic with hand signals, and the whistle blows to move things along. Now fifty years later, I still have the same old "Acme Thunderer" whistle. Early sensors were long rubberized strips that ran across the lanes in front of the intersection. As cars would pass over the sensors, the light system "counted" the number of vehicles crossing. Then at set intervals, the lights would change. Sometimes, a sensor strip would get stuck, causing a "stuck light". We'd stop traffic, and taking a large hammer, go and pound each sensor strip until the lights returned to normal. Fun days.😉 Traffic control by the video sensors and computer have all but eliminated the old "Traffic Cop" from daily life. 👮

When I was a teenager in the early seventies, there was a sensor strip for a traffic light near my home. Sometimes, when there were no other cars around while I was stopped at a red light, I would go backwards and forwards repeatedly hitting the sensor strip until the light changed. It actually worked.

Fun Fact about Syracuse, NY: on Tipperary Hill, the traffic light at the top of the hill is upside down - green is on the top, red is on the bottom. The old story says that the Irish boys of the area kept throwing stones at the light to break it because they wanted the green on top to represent their proud heritage. After replacing several lights, the city finally acquiesced and flipped the light. So if you have red-green colorblindness, be alert if you drive in that area of Syracuse. (The intersection of Tompkins and Milton; you can see it in Google Maps street view.)

The History Guy: Making something as... pedestrian... as traffic lights into a transport of delight.

The yellow light is called amber in the UK. There were public information films that asked "Are you an amber gambler?" which encouraged people to try and stop- not race through the amber light to beat the red light. When I was a kid there were rubber strips in the road that actuated the lights when cars drove over them- so we would go out into the roadway and jump up and down on them!

Officially its Amber in the USA too, but in normal speak its yellow. that is in manuals for traffic signal design the color is specified as Amber, Likely because "Yellow" is very ambiguous but Amber is a very specific shade of yellow.

Great research. You might have added (based on the Jam Handy clips from the mid-1930's) that a common pre-WWII sequence was G-Y-R-Y-G. The extra yellow after red gave motorists a few extra seconds to shift from neutral to first gear to be ready to promptly go on green. As late as the 1960's, I remember signals that were still using the pre-war sequence. Those were old signals that had green on top facing the cross-street, enabling a 4-way signal to operate with only 3 bulbs instead of 12.

Local variants like the Red-Yellow combination for "pedestrians only may cross" of Mass. and RI didn't get mentioned. That Red-Yellow is rapidly disappearing.

I was riding with my dad in a small town in TN 50 years ago give or take a bit. The traffic lights on side streets consisted of two boxes, one above the other. They each had two red lenses and two green lenses with only a single light bulb in each box. Dad happened to be red/green color blind. Scary ride with him 😅.

Ashville, OH has a the "worlds oldest working traffic light". It ran traffic from 1932 to 1982 and now runs inside a museum. It was pulled from service because it is a single lens that changes and color-blind people struggled to determine if it was red or green. It still functions inside the museum, really neat mechanism.

Aviation, which took many of its terms & systems from maritime, also uses the red & green lights on wing tips so another pilot could more easily know if a plane was coming towards him, or away from him.

I was listening to a retired Navy Admiral on the radio here in Australia, who stated that because the British Navy was crashing at sea in inclement weather, they commissioned a large survey to find the best two diametrically opposed colours to use in all climatic conditions day and night. Red and Green was the result of this survey. He also went on to say that British Rail adopted these colours and chose red for stop. One can only imagine what it would be like should they have chosen green but I guess we would all be none the wiser. Thank you kindly for your wonderful videos. Always a delight to indulge.

Your probably my favorite history KZreadr. You cover every topic you can think of. I can’t fathom the hours you put into researching stop lights of all things!

For most of the 20th century, Crestview, Florida had a very uncommon traffic light, near the post office and Piggly Wiggly on North Wilson Street. That one seemed to be the result of someone wanting to see the bulbs do double duty and simplify the circuitry. Thus, while traffic on one street saw the common red on top and green on bottom, the other street had green on top with red on bottom. The only place I ever saw a traffic light go from red to yellow to get to green. Sadly, this rarity has been replaced by a light that operates more conventionally.

Thanks, THG, for green lighting this flashy piece of history. 🚦

@frafraplanner9277

I think traffic lights are better placed on the sides of the road

Learning to drive in Massachusetts in the 60s was unusual because of some unique laws. For example, as well as the usual red and green signals, there was a red then red-yellow signal meaning pedestrians were crossing. Standalone pedestrian crossings had a flashing green light, meaning it could change to red, yellow. There were also two types of stop signs. The common type we have now had different laws. When there were multiple cars in line, every other car had to stop and then the two cars could proceed if it was safe to do so. Then there were the “Thru Traffic” stop signs which required every car to stop as we do now. I believe most of these laws are no longer in effect. Although not a law, entering a highway (freeway) was different. The rule was to step on the gas, enter the road, and then look left! LOL.

Another quirk of Japanese traffic lights is how often they are spread out horizontal, while in North America they are almost universally vertical, with the colors being the familiar sequence from the top down of red, amber green. Except in the Province of Quebec in Canada, where they are quite often horizontal, sometimes with red on both ends, and the green often being much bluer than is common in the rest o the continent, and the red lights on horizontal traffic light often being square instead of round. (This MIGHT be to help people with color vision defects. The most common color vision defect is the inability to distinguish red and green properly. Of course, the vertical arrangement used nearly universally elsewhere still allows for easy differentiation of red and green by being at the top and bottom.) It might also be because Quebec will do things differently in order to not do things the same way as they are done in Ontario.

Three oddities or rarities I've discovered regarding traffic lights - In Germany, the light cycle is red, red/amber, green, amber, etc. The short red/amber indicates the light is about to turn green. In downtown Charleston, SC, there were (in the '70s/'80s) traffic lights that faced due east, and at sunrise, the red light was impossible to see. The city's solution was to add a strobe tube horizontally across the red light that would flash when the red light was on in hopes of getting drivers to notice it. Finally, in Roseville, CA, there's an intersection that is near a high school, heavily traveled during the day, but rarely used at night. The light is "green on demand", with sensors in each direction. During daytime hours, it works as a timed light. However, in the evening, it switches to all directions red. When a car approaches, it instantly turns green for that direction and stays red for cross traffic.

@filanfyretracker

Beginning in the 1830s, some railroads used black- and white-painted balls which could be hoisted on ropes to control train traffic. The white ball raised meant "proceed," and the black ball raised meant "stop."

Back in 2001-02, I lived in Phoenix AZ. There was 1 intersection there were very serious problems with folks running red lights. It was on the news many times because of all the accidents, especially at rush hours. This happened mainly going south. Finally, Phoenix PD took quite drastic steps to fix the matter. They swarmed the area with 3 cars and 8 motorcycles. We'd be driving down the street and commonly see 4 cars pulled over with 1 or 2 being pursued. This went on for 6 months, every day 2 times a day. Weekends were just silly. People would get 2 or 3 tickets- running the light and speeding. If you were a jerk with the cop, you got reckless driving too. The courts caught on quickly, especially to those who got cited more than once

My friend is colorblind and depends upon the position (top, bottom or middle) of the light (as opposed to the color) to know whether it is a stop, caution or go signal. I didn't see any mention of when that was standardized. Nevertheless, very interesting as usual.

I live nearby, and am very proud of the irish Tipperary hill area, in Syracuse NY. Where 'Green reigns supreme!' (only green on top light)

Awesome. Been thinking about this for a while now. It's interesting where cities place the lights for ease. I just came back from Düsseldorf and I had to crane my neck to see their lights. Other places placed a second set of lights in a good line of sight for the driver in front of the line. They also had a system where the amber light flashed before the green came on, like some kind of race. Another quirk was the pedestrian walk symbol come on simultaneously with the green arrow turn so you have to wait for people to cross the road before you could turn right.

Modern improvements include camera detection systems, turn arrows that cross opposing traffic that flash after being solid, amber reflective tape around the outside of the light background.

The Los Angeles traffic light bells survive to this day -- in cartoons! The major cartoon studios were in LA during the prewar years, and rapidly adopted the audio cue to emphasize signal changes. One major argument was over light placement -- railroads put green at the top (the "high ball") and red lower (closer to the engineer's eye line, useful when smoke and steam often obscured forward view). The "stop at top" lights were standardized to differentiate trolley signals and car signals. Los Angeles also developed the "scramble" system for pedestrian crossing at intersections. All cars stopped and people would walk to whichever corner they wanted. This is gone from LA, but still found in major cities around the world, such as Tokyo.

The japanese blue 🔵 colour story is odd and funny 😄 at the same time. When I was little my dad bought a japanese Casio mathemathical calculator that had the display with lighted digits in a sublime "blue-ish green" colour unseen anywhere else. Now after many years, I found out why 😊

Coincidentally I watched a video from Weird History earlier today which explained how we got our traffic light colors. Railroads originally used red for stop because the longer wavelength can be seen at greater distances. They used to use white for go and green for “go slow” but since the green light was just a white light tinted by a cap if the tinted cap fell off it would send the wrong signal; additionally the white lights could be confused with starlight at night. So eventually they changed go to green, and slow to yellow to better distinguish it from red and green. (From the video: “Why Common Items are Specific Colors”)

With regard to their altitude, the traffic lights below the 2,645 metre Col du Galibier are the highest in Europe. They control the flow of traffic under the col as the 1000 foot length tunnel is only wide enough for one lane of traffic. The tunnel was built in 1890. I have crossed the col on a bicycle three times and there are very fine views from the summit.

@@brendanotoole5871 , good song, that! Although, "you stop on the red and you go on the green" comes originally from Mississippi John Hurt, "Candyman".

I absolutely love your videos 😊 Thank you for what you do, I appreciate it and look forward to the next 💯

The first time I saw traffic lights with visible timers showing when the lights would change was in Cairo, Egypt. It all seemed very sensible as it gave drivers the opportunity to switch off their engines etc. The whole concept was undermined by the fact that most drivers didn't actually stop for the red lights. It was almost as interesting looking at the chaos on the roads as it was looking at the ancient monuments.

Only the THG could make a documentary of traffic lights interesting!

THG you rock! Love the channel and content. Peace

Dang i love this channel

Traffic signal is the official name of the device. But this history definitely deserves to be remembered! 😊

A whole lot of history I never knew about. As usual, thanks for sharing this. Your videos are always a joy to watch. 👍 P.S. Love the tie. 😉

As usual, this article was very enlightening. Thanks History Guy!

Red light means stop, green light means go, yellow light means go very fast.

THG: "Traffic Lights will be with us for a long time to come." Future guy: invents augmented reality traffic control, making traffic lights obsolete.

Very enjoyable , we see them every day but it really doesn’t occur to us where and when they were invented.

BMW had an available in-car display on some models that would notify a driver whether the upcoming traffic light was red or green. (2015’s. Don’t know if it’s still offered) Downside, the traffic lights had to have special transmitters to share the information, and most lights in the USA didn’t have it.

Keep it up! We love the information!

One of the things that I wish the USA would adopt from France is a lower light mounted on a pole at street corners in addition to the overhead traffic light. This makes it easier for the lead vehicles to see and also adds a safety factor when bright sunlight makes the overhead light difficult to see.

In South Africa, all our lights are mounted on poles and there are two sets. One at the intersection and another on the opposite side.

I see something like this in some places in NJ, you have the overheads and then sometimes hanging over the oncoming lane another light facing your direction. One near my house like this because there is a corner before the 4 way intersection. Lets you know what the light is doing before getting to it.

Illinois does this a lot, using side signals as well as overhead signals.

I recall bronze traffic lights with a statue of Mercury on top on New York’s Fifth Ave Sometime in the mid 1960s they were taken down

The nomenclature gets to me. To me, a "traffic light" or "traffic lamp" lights up a road, and a "traffic _signal"_ controls traffic.

Great video. What about a video about the development of traffic laws over time?

always love your content.

The old Asheville, OH traffic light is history that deserves to be remembered.

Anyone else have Monty Python's "I like traffic lights" stuck in your head the whole time watching?

But only when they're green

"Red means stop, green means go. Yellow means go very fast." - _Starman_ (1984)

I appreciate you and thank you for making content.

For decades in many rural towns in the U.S., there were only single flashing red lights at intersections. Even years after they installed timed yellow/red/green traffic signals, anyone giving you directions would say "turn at the red light". 😅

There are still plenty of flashing red lights outside of cities today.

Another really fascinating look at what keeps our communities moving.

The History Guy can make the most mundane things interesting.

There is a light in my hometown (Hull Massachusetts) that turns yellow before it turns green as well as red, which is the only one I know of that does that. Not sure why, but it does 🤷‍♂️!!!

I feel that these lyrics might be appropriate here: I like Traffic lights (3x) No matter where they've been I like Traffic Lights (5x) But only when they're green

Lol- the Contractual Obligation Album. That song was playing in my head all day when I was producing this episode.

Traffic lights are one of the most useful inventions ever made. Universal (global) green: go, red: stop is humanity actually showing some smarts.

I've always like the use of a traffic signal in a bar to let you know when last call is. 😁

I was getting ready to comment about how Japan uses the word “blue” for “Green” but you were on top of it!

As mentioned, the modern three lens light we use now was invented by Detroit Police inspector William Potts in 1920.

You should also do the history of Edgar A. Walz, who invented the turn signal in 1925. He got a royalty every time someone used their turn signal. Sadly, he passed away, destitute, in 1947. lol
