At first I thought the cop was gonna give you a hard time about filming or something. It was pretty cool when he fan-boyed you instead.
Ngl I was worried the whole time they were parked since he was talking about how it's a dangerous intersection. Never a good idea to stop at an intersection!
I seriously don't get what all the cop hate is about. Yeah, there are some bad cops out there. They are managed by county officials who keep winning reelection every year and refuse to pay for improved training or enforce penalties for poor behavior. But it's not universal. And again, if everyone hated their county police so much, why keep reelecting the same sheriffs and county legislators? People have so much control over their own police, it's insane. You don't have to win a national election to change the police. You literally just need to win over the people who live next to you in your same county. They aren't far away. Just get out of your home, walk over, offer them a cup of coffee, and talk about who you should be electing for office.
The way people complain about police, it's almost as if they want LESS direct power over their county officials. Are people really so bad at talking to their neighbors that they want someone from across the country to come in and deprive their community of their democratic power to elect their own government? Do people really want a dictator to save them from themselves? It really seems like it.
Super cool!
@@Mathignihilcehk No everyone is a combination of crazy and stupid and no one gives a shit. Society is an illusion. No one is in control. There is too many people, too many opinions, too much cognitive dissonance in the minds of the common folk.
Sad but too many angry cops have created that reputation.
Bro this is a whole ass TV show on youtube for free. Good work.
I like it because it throws at least a little shade on the idea that nobody in the government cares about the country. Traffic engineers care about the country.

Video idea: roads with too many signs. In Pennsylvania it can be confusing and hard to read signs while paying attention to the road, when the signs are hiding behind other signs and objects.
there was a whole lawsuit about NY putting up those I
My mother pointed this out to me years ago. A lot of drivers slow down on the highway as they pass the big overhead signs because they're diverting brain power and attention to reading the signs. Some people even light up their brake lights but have no idea they're doing that.
Yeah there are too many signs here but never enough speed limit signs!!!
I just ignore all of them when there are too many, honestly
And roads with too few signs! Oftentimes I turn onto a road and don't see a speed limit for several miles, so I just have to guess and hope for the best.
In Austria, our traffic lights blink green for 5 seconds before changing to yellow. Pretty much like an integrated warning system.
While way better than no warning, I think the use of smarter systems with very simple signals for us monkey drivers seems better. I guess the problem may be that a light blinking for 5 seconds won't fail as much as plastic radio beacon.
I just realized a lot of times we have that with the countdown timer on the pedestrian/crosswalk signal.
I was living in Austria for 1.5 years and driving was so much better with the blinking greens. You have plenty time to brake slowly and safely. I wish we had this here in Hungary. There are also a few traffic lights in Győr that have timers next to them, which is pretty cool IMO.
As a truck driver I appreciate the crosswalk signs in many American cities that have either a countdown timer or a warning flash. I use them to decide if I can make a green safely.
In Poland, they did that as well (or at least wanted to, not sure if they did in the end) but made it illegal to pass on yellow, so the green blinking just replaced the yellow light, really. It's stupid and probably only serves to ticket foreigners who aren't aware of this stupid system.
This should be shown in Driver's ED.
Excellent content!
They should also tell you that it’s better to just barely run a red light, as there’s usually a several second delay between the other part of the intersection turning green and cars moving because of it, than to slam on your brakes and get rear ended, like almost happened with the car and the semi in the video. There’s much more time than ppl think there is
@@russellwinfree7587 this is why I think red light cams should be banned. They cause unnecessary panic for drivers
They do, at least in my driving school in Berlin
Not all traffic lights are equal
I dunno, that could be dangerous. In my college town, when I heard that the lights through the center of the town were timed to all change at the same time to match the speed limit, I discovered that you could also hit every green light doing double the speed limit !!!! :-P
The LAPD endorsement is indeed a high watermark for this channel.
"I hate this intersection" don't we all?
Was nice to see police cruiser fan stopping by, seems like great dude too
Is this what adulthood is? I see a video on traffic light radars and I know it'll probably be the best part of my day?
Great video as always Rob! You continue to kill it with these, I found this topic extremely fascinating.
My dad was a truck driver for my entire childhood, including when I was learning to drive. He taught me to pick a "bingo" point when approaching a green light. If the light changes to yellow before you reach your predetermined bingo point, you will be stopping for the red light. Once you pass the bingo point, no matter what the light does, you won't be stopping. This technique also allows you to begin paying attention to the intersection, rather than worrying about what the light is doing when you're approaching the collision zone of an intersection.
Driving this way was very helpful when I started driving Semi trucks, and I still use it regularly when I'm in my car.
We call it the point of no return, but it changes of course with the speed. But with the front car in my mind of course.
those videos are always so entertaining. The way it's cut, showed and explained is good enough for a TV show.
There is a production company putting this all together and he's not exactly an amateur.
@@PhilLesh69 pretty sure it's like 99% him.

Your production values are wayyyy up man, good work
I've worked with radar before and creating a working radar that faces towards the ground is extremely difficult. The fact they've done it is extremely impressive.
3:59 It's a bit of a myth that motorcycles can stop that much faster than cars, but we can sure as hell accelerate faster than them
True. This myth likely exists because motorcyclists are willing and able to push their machines limits, and use all its braking force, while studies have shown average car driver is almost allergic to stopping force. They'll hold back pedal pressure and not stop with anywhere near full capacity.
They even experimented with braking systems that required less pedal force, and drivers simply reduced force even more.
Average driver has no idea how quickly a car can be made to stop, and don't seem to realize ABS means they could stomp on brake with all tbeir might and car will simply stop safely and at max capacity.
Sad and scary. If you're not a driving enthusiast, please do everyone a favor. Go to empty parking lot, go about 25mph, and absolutely slam on brakes as hard as you can, without letup until full stop. Do this several times. Then do it yearly as a reminder. Let your brain premap what max braking feels like, so when you need to do it, you won't hold back.
Note, of your car is so old it doesn't have ABS, then you're an automobile enthusiast, and experienced with what happens when you exceed tire traction while braking.
I think it's so cool you got kudos from the LAPD. They were impressed and so was I.
OMG I got to send this to my frequent "back seat driver" friends whom argue with me about this.

Yes, works in sand storms. This same tech is in smart weapons and a technology called synthetic aperture radar. It basically creates images using radar waves and can see through clouds / storms / sand storms, etc... The latest weapon using this is in-fact called "StormBreaker" because it works in all weather conditions.
Hey Rob, greetings from Germany, your videos give a fascinating view into american road traffic, its crazy how different it feels for somebody knowing traffic in Europe, but then even here it feels different from country to country.
Same thing here, it's different from state to state sometimes!! Every state is s different country withing a Large one. Greetings from a Nicaraguan living in the US. Auf Wiedersehen 👋🇳🇮
I dated a German for several years when I was younger.
There were several things that drove her crazy about American drivers. Barely any use their turn signals and almost everyone camps out in and blocks the passing and turning lane (left lane on any divided highway). She would yell at drivers who changed lanes or slowed down to turn without warning. She thought they were dangerous scofflaws.
@@PhilLesh69 What’s also so annoying is when drivers pass you on the right on the highway or someone you want to overtake is driving slowly on the left lane. It’s strictly forbidden to do that in Germany - they take your drivers license away for up to 3 month!
@@simonkraemer3725 Passing to the right on wide highways is only forbidden because it is dangerous, and only dangerous because it is forbidden.
Once you break that circle, it is perfectly OK to pass to the right side, and it makes more effective use of the roads possible.
Especially those 4-5 lane wide (per direction) highways around cities are used very ineffectively when passing to the right is forbidden, and they rightly noticed that in the USA and made it allowed to pass on the right. When that is allowed, eveyone watches the lane when they move to the right, and it is no longer dangerous.
@@Rob2 Well, no this rule makes sense, it’s also forbidden in the US to pass someone from the right, except in certain circumstances; the police just never enforced it. Besides having freeways with 4+ lanes doesn’t make much sense (after three lanes you have to think about better mass transit), you can get in dangerous situations when driving slow on the left lane. People that want to speed have to pass slower moving cars in zigzag courses, every lane change means a higher risk of collisions. A study showed that driving 5mph faster on the left lane is less dangerous than driving 5mph slower. With a strict enforcement of the no-passing-on-right-rule in Germany, we can maintain a highway system without any speedlimit with less fatalities than in the US.
Man, it's like you've been doing this your entire life! I saw old news clips of you but I think you just have literal raw talent. Road Guy Rob has quickly become one of my top 3 favorites.
*you know it's a good day when Road Guy Rob posts!* _u rock dude_
I saw the same exact radar thing on a street light at it sets off radar detectors😂😂
Rob,
There is typically PVC conduit(s) that run from the base of the traffic signal to a quazite / electric junction box near the main traffic controller. There usually run additional conduits for future use where they can run additional wires as needed with just a fish tape.
In the past, I'm sure some TH-camrs would make a video like this with stock footage, reading from a Wikipedia article more or less. Rob's videos get right on the scene, with informative and amusing graphics clearly illustrating his message. This is interesting content, well presented! If I saw you standing on a corner in your safety vest here in Portland, I'd make sure to say hi, Rob!
damn i love the tatu reference :D
When I went to Mexico in the 90s, I noticed the green light would blink five times before it turned yellow. That would be a cheap solution to get rid of the dilemma zone discussed here.
Exactly. No need to install a separate sign to warn you that the light is about to change.
Blinking greens mean something else in the US! Although they aren't used much, it indicates that the intersection is a crosswalk only, no crossing vehicle traffic.
i'm from Mexico and I thought that happened everywhere
When the green light starts blinking it's time to decide whether to step on it or to brake
They have those in Russia too, not sure why more countries don’t use them.
In some places in Europe the blinking green light is used as well, e.g. Austria. In many other countries I saw displays counting down the seconds. This also appears to be a much cheaper solution. I wonder if the radar-based solutions has other advantages, which justify the effort.
!!!
I was just having a normal Tuesday
Now it is a great Tuesday!
Have had a few of these over the years resulting in two (fairly light thankfully) rear-ends and in one case a pickup shooting by on the grass to the right of me. Part of the problem is the split-second of indecision can mean that you end up braking later and harder than you would if you knew for sure you were going to have to stop.

Your channel has been so entertaining to watch, I swear every time I've been out driving the past few days the lessons of these videos has been in the back of my mind
Let's hope future transportation engineers are picking up some tips from you! 🚙 Great video as usual!
HOW DOES THIS CHANNEL HAVE LESS THAN 100K SUBS?!?!?!?!?! The production quality alone is AMAZING.
Grand island nebraska has the warning flashers on alot of lights and they're awesome. It starts when the light is still green even. Slow comfortable stops
@9:00 Love that that guy recognized you.
Happy to see your sub count way higher than the 4K I arrived at. You’ll be at a million one day.
Excellent review. Now I will be distracted at the intersection looking for the sensors. ;)
Was not expecting that from the police cruiser stopping
5:00 the thing about these flashers is they're not always timed the best. There's one near my house and when it's starts flashing, you have about 5 seconds of flashing where you will make it. So what's the point?
I've noticed the same thing. There's one near me that I just ignore because it's always wrong.
Probably just a poorly set up one. I really like the ones near where I live.
Where I live in BC Canada we have flashers
On every road with a speed limit of 60Kph or faster and they are all like that
Here in Brazil some cities started using traffic signals which are countdown signals, so you always know how much of a green light you still have. I´ve always wondered why this hasn´t expanded worldwide, there´s got to be a catch, but my experience with them is great. Most of the problems go away when you know exactly how much time you have left.
People will speed up to try to beat the clock.
Maybe have flashing green to tell you it’s going to turn yellow but not know how much time exactly
You are simply the best. Period. I would pull over if I saw you too
Looks like you're becoming a bit of a celebrity with the police fan interaction. That's awesome! Just like you said, I don't think you can top that! Nothing better than having law enforcement officers on your side! Of course they had no trouble spotting you with your signature green collard shirt, bright orange vest and microphone. Great video as always! Look forward to watching more!
Edmonton, Alberta NEEDS these detection thingies... I did some UberEats last night from 3-5AM and stopped at SO MANY red lights despite no cars coming from any direction at all.
That’s because the loops in the pavement where you live are set to trigger red lights. It’s the exact same thing where I live. There could be no cars anywhere on the intersection you pass that loop and boom you get a red light.
@Go Clunker I assume they're trying to grab red light camera revenue?
@@EMichaelBall they call it “traffic calming” waste of brakes, fuel, and risk of accidents.
You do notice the extension if you pay attention to the crosswalk signs here in Ohio. When in that zone driving and the crosswalk stops blinking I know it added that extra second or three! If theres no cross traffic, the crosswalks automatically cycle back to white instantly if they don't go red instantly when you're still farther away; all telltale signs of this few second extension feature. I always read those crosswalk numbers for an idea how stale the light is and imagine they've designed them intentionally that way?
It's kind of an accident and can work if you're familiar with the intersection. It is by no means a rule though. It can be programmed to have a longer green than the pedestrian phase.
Also there isn't anything on the market that extends the maximum green timer, if you hit it the signal goes yellow even if the radar says someone is in the bad place.
Probably one of the highest video-quality to subscribers ratio of any channel on this site
I genuinely look Forward to every video from this channel. Very interesting exciting videos !
I really like these videos, the road infrastructure covered in great detail and explained interestingly and with bit of fun too!

Great video! I've noticed countless times where a green light "helpfully" turned yellow right as I was passing underneath it. I figured it was thanks to some sort of advanced detection system, but never knew any of these fascinating details.

that "viewers like you" comment at the end was great, glad im not the only one 😂

Interesting intersection at 2:44. I have never seen a left turn like that.
It's conceptually no different from a regular left turn lane except the median is really wide; the left turn lanes are so far separated from the rest of the road that there's apparently no risk of being sideswiped.
It's just that this one is really close to a three way interchange (that is, that is the last level crossing before merging with another freeway, or the first crossing encountered after exiting), so imagine not having the traffic light there. Because that's exactly what it was like several years ago.
You are doing a great job Rob. This channel will get big and inspire many people to pursue a career in road design/traffic engineering.
just wanted to take a moment nd thank you for your great, concise presentations.
seriously, great job Road Guy Rob.

Interesting, really informative video and the police jumping in was awesome! I wonder if these radar systems can also be used to change lights faster when they observe a vehicle exceeding the posted speed limit. I would say that I observed this very phenomenon except that I have no way to verify that it was happening in that way and not simply because I exceeded the speed limit for a fair distance and that caused the lights to seemingly change sooner. I'm talking about a difference of 5-10 MPH max...not extreme considering it was very early morning and almost zero traffic. One light changed rather quickly to yellow, plenty of room for me even though it went red as I drove under it, I then noticed the very next light changing as well even though there was no cross traffic near the light. It was a main thoroughfare so it seemed likely to me that they might have done this.
Ha! At 13:00 you were driving on Red Hill in Irvine, CA. I love it when I recognize where you are! Great videos, ketyo up the great work.
Your editing is on point - many professional TV shows aren't put together as well as your videos are, keep up the great work!
"I was driving lights and sirens and got T-boned at this intersection" means "I failed to properly clear the intersection before proceeding though the red light".
Sometimes I look at the crosswalk timer counting down to determine if I will make the crossing or will have to stop.
This should not be done.
Your one of the reason why driver especially these turning hates pedestrians. Technically your j-walking when you start crossing after the stop hand or counter starts
Your videos are so amazing. Awesome stuff!
Great video Rob! Love your content!
You are legit one of the best creators on the platform. Keep up the great work!
Why not just have a big countdown display above the traffic signal? That way everyone could figure out what to do individually. A loaded semi might want to get ready to stop sooner whereas someone driving a car might know to speed up a bit to make the green.
If you watch signals from other countries they have these and they also have green lights that flash when they are stale. In the USA the revenue is needed from tickets and body shops also need the business
Cost, cost, cost? It'd be a novel device, so it'd take some getting used to; might have resistance from some people. Adding another electronic device to the bar is probably not cheap (materials, road closures, integration, ongoing maintenance, etc) and you have to do thousands and thousands of intersections. Or, plug in this radar thing and ... done? No learning curve.
My hometown in Canada has the advanced flashers! And you definitely should be slowing down and stopping
This is the best, most honest traffic technology channel I have fver seen.

They don't care about whether or not we crash ! They want all that money from those red light camera tickets !
This whole video is about a technology that contradicts your theory.
Rob, I wonder what pedestrian walk-signal countdowns do to this situation. I'm in a big city where they're on every block. I can't tell you the number of times I've seen drivers hit the brakes well *before* the light turns yellow! I have a dashcam + just uploaded a 20 second example clip. He hits the brakes when the countdown still has 3 or 4 seconds on it! I'd be really interested to know what you think of this situation, Rob!
