The Hidden Cause of Traffic Jams-and How to Solve Them
ฝัง

- Some traffic jams seem to happen out of nowhere-it’s not rush hour, no construction, no accidents. These are called phantom traffic jams, generally caused by drivers tapping the brakes on and off. Could autonomous vehicles eliminate these traffic jams, and make our roads safer? Some researchers think so.

Um, I think the best way to reduce traffic is to have better public transportation like trains, trolleys and busses rather than having so many individual, single occupant cars. Just saying.
@@nyimakgan Some cities in the US have started implementing better public transportation and enacting zoning laws which allow mixed use for more walkable neighborhoods. In the longer term is definitely *is* more profitable to do so. Unfortunately the suburban sprawl is how most cities here are designed for, which is just terrible and a *huge* financial drain on every city.
@@nyimakgan A video about suburbia and city planning that I hope you find as interesting as I did: th-cam.com/video/7Nw6qyyrTeI/w-d-xo.html
Or motorcycles
Remove the idiots
@@vgrepairsmotorcycles fix the problems of traffic but they are not the best because they’re extremely loud and heavy.
"Well thank goodness. We found a thing. All we have to do is get half a billion self-driving cars on the road. Now we don't have to consider building decent public transport."
Lol perfect pacifist answer...
Exactly.
As in modt problems, there will need to be an integrated solution.
🤣🤣🤣👌
When RI offers free buses from Providence to the South County beaches in the summer, hardly anybody rides them. Americas want their own car to carry their own stuff. Usually the people advocating buses, are the people who never take them.
How about we reduce the number of cars on the road by building better mass transit?
So, it's caused by people driving like idiots.
I can tell you quite how often I see cars braking for absolutely no reason. Theres wide open space in front of them, no traffic lights and they still decided to brake
Yea it’s so infuriating, or the speed of traffic is very clearly 5 over but 1 or 2 cars decide they don’t want to do that and go 5 UNDER and intentionally won’t let people pass them leading to a block of congested traffic purely from the two cars in front being fucking idiots
Whever I run into these slowdowns for no reason, I try to not alter my speed as much as possible. I'd rather go 30mph constantly than aggressively switch between 45 and 15 at a moments notice.
So does that mean I'm driving right? Too bad you'll never get drivers to move in unison with each other.
Cars cars cars.. no matter how much we spend on roads and now matter how big we build the roads it will never be enough. When ever I ride my bike or take a train or bus to get somewhere I feel liberated and happy to not be in my car.
But real freedumb is a monthly payment at 5% APR, $800 on insurance/year, $60 on gas/ week, $200 in yearly registration fees to the state, smog check fees, maintenance and upkeep, oil changes every few months, tires every few years, daily stress from sunrise- sunset from daily traffic gridlock.
So much freedumb! I can drive anywhere I want! It just costs me several thousand per year to have the freedumb to own a depreciating asset and get stuck in traffic for 30 minutes on a 3 mile stretch of road! Daily! That's America baybeee, I wouldn't have my freedumb any other way.
come on encourage the freedumb-dependency@@chrispadilla4027
The worst drivers are the ones that tailgate, blast from traffic light to light, pound the brakes and gas pedal. They tailgate, and are often very rude. If we all would slow down, stay back, we could save time and fuel, and maybe lives.
And speed limit signs don't mean that's the minimum legal speed!
As much of a pest the aggressive drivers are, I see them as no more of a danger than the ones who drive under the limit in heavy traffic, especially when they hog the overtaking lanes. Either slow drivers are timid on the road, they're clueless and have no awareness of basic common sense and of the rage they're causing to others (some are even under delusion that slowing everyone down makes the road safer), or they know they're slowing everyone down and just don't care. In any case, there needs to be a crackdown on these useless drivers. We've all had the horrible experience of being bullied by some blowhard behind us trying to be tough, when the situation is not even our fault because of the slow f$%kwit infront of us.
@@eddielong8663 Aggressive drivers are very often the ones clogging up traffic because of their selfish behaviors. For instance, an aggressive driver cannot bear to merge into a space in smoothly-moving traffic. Because of their mental defect, they must race to the end of the merge lane, force their way in at the front, and cause everybody behind them to have to brake or stop. In the case of a phantom traffic jam, aggressive drivers are already tailgating, so they will have no time or space to avoid slamming on their brakes and intensifying the jam when they reach it. Just because it looks like they're going fast doesn't mean they're getting out of the way-they're spraying diarrhea all over the road behind them.
@@Nupetietgoing to the end point of the merge is technically what you're supposed to do. It's called a zipper merge. And, when done properly, integrates both lanes seamlessly. Otherwise, you have multiple vehicles from the merge lane entering in front of the same vehicle at different points, causing drivers behind to become agitated at a system not working fairly.
Studies have shown that vehicles merging only at the end point results in better flow.
@@jodybond Can you show me one of these studies?
@@jodybond P.S., I rarely see drivers keeping up with traffic to reach the end of the zipper. In almost all cases, they are attempting to race as fast as they can (like 20 mph faster than traffic) to the end so that they can jockey for position. They will pass up a wide open gap meant for them because they want to gain one additional car length. This makes people resentful, so nobody _wants_ to let them in, and the problem is compounded. Get in where you fit in!
It would work with regular cars if everyone drove the same speed and didn’t rubber neck. People are always the main contributing factor to every problem.
Right. 100 years ago, traffic lights were going to cure congestion. Then, in 1939, freeways were identified as the answer. In the 1960s better freeways were the answer. Now, these cars are the answer. Spoiler alert, there will be more of this as long as we depend on POVs for mobility. Thousands of vehicles in every city will never be the answer.
Where are the trains? Hello????
I have seen traffic jams by "rubber neckers". One time on Rt. 93 going from Massachusetts to New Hampshire. The north bound lane was going fine(I was traveling south). Then there was a car off the road and looking like people were checking their cargo. I noticed cars slowing down a little too see what was going on. They started to bunch up until a
couple of miles down, they came to a complete stop on all 4 lanes! This stopped the traffic almost too Boston . Just because some people were nosey at a car that had nothing wrong. I thought that was unbelievable!
How to solve them… uh, mass transit? Lol. To be honest I’d prefer accesible mass transit as opposed to spending hours in traffic every week.
Mass transit isn't possible in alot of places
@@varus113 To some extent, buts definitely underfunded and neglected in a lot of places where it is possible.
Agreed in cities and populated areas it's a must have but for some like me I commute an hour to work because of where I live. It's hard for many rural people to even thing of public transit as a worthwhile investment. Which is sad
@@varus113 Not with that attitude.
@@varus113 Trams and buses could be used in places where rail is difficult. Trains can be used to connect the rural with the cities.
How about coasting slowly when people are doing the stop n go? Just give yourself a little distance. In a short time the stop n go clears up
The problem is that people will take advantage of the space you leave in front of you and sneak in.
In 1999 I remember seeing a third party product that used ultrasonic radar was added to your car. There was 5 led lights on a small box added close to the gauge cluster. They represented the following distance in seconds Red was less than 1 second. Two Yellow for 2 and 3 seconds. With 4 and 5 seconds being green. Device was dumb, and it did not know if you were going 20 mph or 70 mph but it was factory calibrated to report the following distance time for 55 MPH.
The guy who built the product said that two major auto manufactures had agreed to buy a license to use his product. But it never materialized in the real world. The closest thing today is adaptive cruise control. With a similar system being integrated into the cruise control.
Safe following distance practices is a must. And having a safe distance gives you a better picture down the road. brake taping needs to stop. And many time's cruise control is turned off with a brake tap When a button toggle could be used most of the time.
"If you leave a gap, folks will constantly cut you off", in reality not as much as people believe. I regularly leave at least double the gap most folks follow at. Sometimes people get in front of me. Know what? It doesn't much bother me, and I get over it.
@@inyobill Plus, part of the point of leaving a gap is so that other drivers can merge or change lanes as necessary. When somebody gets in the space I've left for them, it's working as intended.
@@Nupetiet Buh, buh, buh, but, I can't let someone in front of me! That would destroy my manhood! Of course, one avoids investigating what that implies in regard to one's alleged "manhood". I've noticed that, very often, they are just transitioning to the next lane over and are soon on their way, no disruption has occurred, manoeuvres are executed safely, and everything's hunky-dory.
I heard about a car that pulls several other cars on a fixed path that for the passengers is autonomous. These cars are both capable of higher capacity, and less lanes are needed.
You mean a train?
For we folks who share the road with other human operated vehicles, the answer was given in the first 60-seconds of the video; STOP TAILGATING!
It's unbelievable how many people don't know this.
You have so much belief in self driving cars. Yes, they can fix some minor issues like phantom jams. However roads will be soon congested again because of induced demand 🙁
Train good, car bad.
...listen...most folks (myself, my city) do not live near "any" trains...and It's "Elon" and I would surmise your a little miffed he has couple bucks more in his checking than you...something else to ponder...Elon lives in a 50K manufactured home...
TLDR: Bad drivers cause traffic jams. DUHHHHHHHHHHHHHHHH
Anything to avoid public transit
Or you could string a bunch of vehicles together so they all accelerate and stop at exactly the the same rate. We could call it a train.
I believed this was an informative video but it's only an advertisement for Tesla.
the better way to counter traffic jams is to use public transportation on rails
1. Get better transit.
2. Reduce the width of highways and other roads.
3. Make parking expensive in the city centre
The number of cars on the roads will be smaller = PROFIT
Actually we only need to set aside special lanes for autonomous cars, or at least cars that connect with an automatic speed controller connected to all the other cars so that computers can choregraph the flow.
Seems like the road layouts of the east coast were originally designed for horses, and they're just sticking with it.
Design speed matters.
The amount of space that you need between you and the vehicle ahead is roughly the distance it takes you to stop. The time needed to stop after you start braking is proportional to your speed, but that means that the distance needed to stop is roughly proportional to the square of your speed. The number of vehicles that can go along a stretch of road per hour is the speed divided by the distance per vehicle, which is roughly the speed divided by the square of the speed. In other words, throughput capacity decreases with speed. Turning that around, when demand is high, in order for the capacity to be enough for the number of people trying to use the road, the speed has to be low enough. When the speed that people are trying to go is greater than the speed at which the road has enough capacity, people on less-crowded parts of the road will catch up with those on more-crowded parts ahead of them, which slows those parts further, which makes more people catch up, until there's gridlock.
Narrower lanes and sharper turns make people drive more slowly. If the design speed were low enough, that would prevent traffic jams.
I was driving in the middle of nowhere on I-15 between Las Vegas, NV and the Arizona border. There was very little traffic. The 2 lanes were merging together as 1 lane for construction, etc. They warned us several miles in advance. Every car could have easily been in 1 lane and had several semi trucks with trailers between them. YET, some drivers thought they really needed to pass the cars that were going only 80mph right before it turned 1 lane. What happened? A miniature traffic jam where it turned 1 lane. Why? Because of rude and impatient drivers. Yeah, we all had to slow down because of the rude and impatient drivers. I have often been other places with heavier traffic than that, that also merged to one lane and there was no traffic jam. The faster the maximum speed, the heavier the traffic, and the ruder the drivers, the more likely a traffic jam. By the way, I do think there are some methods to help the "merge into 1 lane" problem, but it would take more traffic cones (but I think it would be worth it).
the hidden cause is following distance. we learned about that in driver's education. if you use your brake pedal outside of actually stopping then you aren't a good driver.
Precisely. Good drivers don't come close to tailgating. Increasing your following distance allows adjustment to a decrease in speed of the vehicle you're following, usually just by lifting your foot from the accelerator pedal. You shouldn't be braking every time the vehicle in front of you slows to make a turn, for example. If you are, you're following too closely. Braking converts your kinetic energy into heat and disippates it (wasted gasoline).
Not to mention the fact that tailgating is annoying, pointless, and dangerous.
OR...we could implement more and better public transportation like the European model. Our Trans system is intentionally designed for people to buy a car to get anywhere. I call that your typically greedy American transportation system; for sure, backed by all auto companies
Star Junkie, you hit the nail on the head. Meanwhile they both keep asking for government funding/subsidiary but the only thing they do as soon as it comes in they give themselves a big pay raise and that is only the guys at the top. Two years later they do it again. Same for the post office subsidiary comes in and a big pay raise for them.
@@billgreen1861 and the oil companies too!
The European highways, even with the better public transport web, suffers from much the same problems. Drivers here in Germany are better trained than those in the U. S. (I drove in the U. S. most of my adult life), but many are far from immune to being unaware of the issues they cause.
@@billgreen1861 Yeah, the exploitation of the public taxpayer's taxes never ends. Ever. That's why our infrastructure looks like that of Bangladesh. Crooks; all of them.
Yeah.
And cycling or walking also take up so little space and costs so little to implement, one American bridge costs to same as all of the Netherlands bike infrastructure (a country with +99% cycling population)
Not Just Bikes, Strong Towns, and even the game Cities Skylines all prove this to be true in high (and even low) density areas as a solution to traffic
Too much emphasis is on transportation not enough on the distance between destinations.
I used to have to commute on a highway on which all the smarter drivers know this is a thing (which I call it an accordion wave). Of course, that means there are drivers who don't know how to prevent this.
I see drivers on the road that believe the fastest way to get down the road is to always drive as fast as possiblr. I also see drivers like me that know traffic is slow on a section, find the average speed traffic is moving, and drive that, leaving a bit of buffer in case of a bit of a slow down.
In Delaware on route 1 there are many busy sections that go from 2 to 3 lanes for entrance and exits, then down to 2 again. All the idiot drivers drive along in the exit only lane and then merge at the last second to get back into traffic for 95. This is the reason for constant bottle necks on DE 1 going north or south. It was not a well designed expressway to begin with but there are train tracks all throughout the area. Yet no sort of public transit other than buses
In heavy traffic I moderate speed so I never have to stop and I notice the car behind me never stops either.
This doesn't make sense to me. Not saying it's wrong but if it all starts from someone braking a little bit ( to keep distance from the car in front of them) then, the domino effect should result in everyone behind them braking the same amount and then returning to normal speed at the same rate as the first driver did. I don't see how it results in stopping all together and causing a jam. It would make more sense that it starts from a driver moving too slow compared to everyone behind them, causing a line of free flowing and well spaced traffic to converge and compress into a jam. And when the driver in front exits the freeway or speeds up it takes a while for the line to speed back up and return to healthy spaced out traffic.
Stuck in a traffic jam. Or should I say "Trap-fic Jam".
One evening in Phoenix on the Loop 101, the red Ferrari next to me was having to drive at the same stop-go-stop-go pace as me. Some how I felt vindicated that an old junky car like mine was on equal terms.
How we drive creates this thing called traffic: We treat the posted speed limits as the MINIMUM speed to be driving, and we all rush up to controlled and semi-controlled intersections.
If we learned to leave point A a little sooner, and drive at or JUST BELOW posted speed limits, this would spread drivers out and we would still get to point B on time.
For any automatic system, it still becomes necessary for human control, in that for correct operation a h7man must still. Input a suitable program. Snd if there is no outside overriding influence, an automated vehicle will drive into what could be an accident scene and not deviate to avoid such a scenario. While this video looks at “ Phantom” slowdowns, humans determine if a slowdown us necessary as at interchanges and normal traffic use for a particular time of day. Any automated system would actually follow the same protocol as it would need to determine the number of vehicles entering a lane and the program necessary to reach the given destination. Then there us the nature of highway design. Not all interchanges are highway to highway, there are both on and off ramps to local streets, which have local controls and some designs have entrances and exits opposite the standard. Even for highway to highway interchanges. The other consideration is the distance between on and off ramps. For both local and highway considerations. Even with auxiliary entrance/ exit lanes, an automated vehicle will still have to vary speed for the conditions as some vehicles will be merging in both directions simultaneously this is part of what causes “Phantom” traffic jams.
Big reason is people not paying attention to the road
The cold weather they are failure to keep apart. The construction zone failure to drive less speed than the post speed. While we have lane ending in the construction they fail keep apart they will cause impeded traffic
Watching this in traffic jam
so rather than investing in a proven method of mass mobility and transportation- that can be implemented RIGHT NOW- like high speed rail.... we're just going to pretend like self-driving-cars are the sole solution to human-caused gridlock? How is that supposed to work? Either you can have all human drivers or you can have all automated drivers- but, having a mix of both is a recipe for disaster- as the video demonstrates; humans are absolute idiots and would only impede the automated system. How many years worth of gridlock do we have to suffer through before a bunch of private entities finally throw enough cash into developing a functional automated driving network? Are we supposed to expect every driver on the road to afford an automated-equipped vehicle? Do we live in a magically just world where there are no financial-barriers-to-entry and where wages are equal and where adoption of such a technology would be so *easy*? Is the consumerist automobile culture environmentally sustainable? Are the raw materials for so many individually-owned cars with fancy computers available in great abundance? Would the automated network that the cars communicate though be protected from cyberattack? malicious hijacking? private corporate or government surveillance? network downtime? glitches and bugs? I think I'd trust my own brain and other human's brains over a computer to be in charge of a vehicle. A computer program is only as good as its programmer; and I wouldn't trust some silicon valley dorks to write foolproof code that my life would literally depend on.
Automated vehicles seem like an obtuse solution to a problem with an already exisiting solution.
The problem with self driving cars is people are going to start living farther out of the city. Thus more and longer commute won’t be problem because one can do something else than driving. So it will not be more environmentally friendly or reduce cars on the road.
All self driving cars are electric... Pollution is not the problem here.
@@HenrikLaurell In an ideal world that would be great, but almost all the charging is currently from non-green energy.
@@AmandaPandaPowell that is two different discussions. An electric tram or train has the same problem if you choose to go there. I like to be able to choose transportation, public or private. Not forced to either way.
@@AmandaPandaPowell Do we really want all people to live in the center? In what way is that a good thing? In most countries the country side is getting more and more deserted. Can't see any good in that either..
@@HenrikLaurell Agree. 👍
And block traffic change direction as well as merging that why overcrowded in peak hours
Just leave more space between vehicles and consciously try not to touch your brakes.
These things apparently need to be "rediscovered" every to often. This effect was extensively documented back in the 1960s and the solution (only human drivers in those days) was to allow at least 4 seconds between vehicles. That is, when the car in front of you passes a point on the road, you don't get there for 4 seconds. If the vehicle in front of you slows, you have plenty of time to react and seeing whether you need to brake. it gives the line of cars some "elasticity", allowing minor speed adjustments to be confined only to a couple of vehicles in the line. But then there is the incompetent drivers (speeders, distracted drivers, etc.). For them we need 100% enforcement. Weaving, tailgating, speeding, etc., must ALWAYS result in citations and fines and, if habitual, loss of driving privileges. But too many people think driving is a right and no system will be allowed to monitor their actions.
A car every 4 seconds means less than 800 cars per lane per hour(how much is less depends on the average length of the vehicle) ... Some motorways in Germany have throughput of 5k cars per hour, which is like 1k7 per lane, which corresponds to two seconds distance.
If you add lanes, the effectiveness even decreases.
it only takes 1 stupid person to cause a traffic jam
Time plan arrival to destination that on interstate Hwy 40 mph per hour in the nine 55 mph or 65 mph or 70 mph. If we have more cities along interstate Hwy. the speed can về plan at 25 mph to meet appointment. The room apart must retain or too much traffic will impede traffic and gridlock traffic
Ray Kurzweil has a really good prediction on but what happened with self-driving cars and non self-driving cars and the way they'll become illegal, legal etc. etc... Everyone should look into that, it seems pretty obvious once you read it and even before that. But yeah I think he's going to be spot on with it...
Usually its because someone changes lanes at the last minute for a exit.
When the researcher mentioned that automated vehicles made sense in "predefined routes" it made me think that we should be automating buses and light rail systems instead of cars. It sounds like more bang for our buck
And lead accident no more driving with other broken lane in side 150ft for local as well as on interstate inside 740 ft. Must help traffic in between easy and readjust room apart or impeded traffic.
The Tesla one pedal thing definitely felt like making this issue worse. Cause the moment you let go your gas pedal, the brake light lit and causing ppl behind you to brake, especially when you’re driving fking model X that block the whole view up front
The less traffic it is the complying safety The readjust room apart they are not hold back traffic merging and changing direction. That the reason stop on broken lane must be out side 15ft and on interstate Hwy must redo out side 150 ft. No more adjust distance apart 3 or 4 second it is not ready to deal with overcrowded lane.
people really do not know how to drive. If everyone really kept a car space or two between it would continue to run smoothly
Please start in Houston. Worst drivers In The country.
Instead of developing regions and rural areas, farming, etc. They are trying to take away cars from people.
Learner drivers, elderly and strollers. Silly even if the road is clear someone controls the traffic.
No more drive in blind spot with other lane.
That is right keep those electric vehicles in the USA, up here in Canada it gets cold and the Batteries freeze and need to be replaced.
Ive noticed its mostly trucks, hills and curves. Trucks slowing down, curves and hills cause all the braking.
Phantom jams ? A better term is needed. Panic starts phantom Jams .
People in a hurry going down hill on 405 and merging traffic makes people hit brakes for hours.
The post speed or bellow post speed and parking traffic and stop no tailgate
We will invent the distance measure between all broken lanes traffic. To ensure driver not to drive to meet traffic all lane up front and merging lane device we will install the distance measure in the new snd old vehicles. So they are must not stop inside as well from 1 mph to post speed must keep loosely apart for driver or more changing direction or merging.
A bit difficult to hear because of the added background noise.
I like to call this the slinky toy effect.
This is going to take longer than what these people think, because they are building smart cars, but what we need is smart roads
Learned the root cause of phantom jams as a shorter Recruit in the Marines. If you know, you know.
Spacing! Increase your follow distance!
A bad carpenter blames his tool. A bad engineer blames the user. Just design a better highway system, eh?
Driverless cars will not end traffic jams. But cause more traffic jams. Because people in cars would slow to see who is controlling. The driverless car. And then cause accidents. And if we had only driverless cars. What do you do. If someone attacked you. And you need to get away. You jump in the car. It only drives they speed limit. You'll be attacked in lower speed zones. And be shoot. And the who drives emergency vehicles. You house is on fire. But the fire truck has to drive with traffic. And if someone says make a program. So cars more aside for the emergency vehicles. Then what if I set 10 fires. All the near by stations set trucks to those fires. As they are busy. I set your house on fire. Because it's what I really wanted to burn. Driverless vehicles will never work 100%> you need people in them controlling the. Driverless cars will not stop deer from jumping in front of cars. It will not stop trees and things from falling to block the road. And if your good at hacking into computers. I'll hack your car and cause it to not start. Some many things you don't consider. As to why you couldn't do it 100% I could go on for years. With ways it's not going to work.
"If we wanna do better, we as humans should not be telling the automated systems what to do or else it will just reflect back our.. uhm... uhh.. our imperfections..."
That's nice way of saying stupidity lol
These people did use brake and pedal gas for squeeze. These peoples must receive warning or discipline explanation to the traffic judges. Without do the above they continue use brake and pedal gas hanging around traffic that caused us in congestion and accidents forever.
Just shows that there’s always that’s one person..,
Its simple! To many people in a big hurry!
No, just too many people.
Just figuring this out now?
The tailgate make traffic overcrowded and lead accidents
Yup, a couple grandpa’s or grandma’s on the road would do it..
Camaro, the older you get the slower you'll go because, no one wants to get to the " finish " line first. After all ' He' would be the only one to greet you. So slow down enjoy the view, smell the flowers 💐 before you can't and remember you'll be slow too someday.
Safety first and caution is always warranted, but we have many drivers who are over cautious and slow down on the highway for no good reason as if there aren't fast moving vehicles behind them who will be forced to respond. They also stop or slow down on city streets at the slightest possibility of another car entering the roadway, and they hesitate when entering rotaries even when the only traffic in the rotary is on the other side of it and poses no conflict. They spend excess time at stop signs after looking both ways and it's clear there are no approaching vehicles in sight, I've even seen many of them look in their rear view mirror at a stop sign, looking for God knows what. The purpose of roads is to move vehicles, not to park them!
I beg to differ. I see taffic jams caused either by slow moving 18 wheelers and slow drivers that are on the left lane driving under the speed limit. This is worse when you have a 2 lane highway. Most of the slow drivers are already on the right side. But there is always sprinkled here and there slow drivers on the left lane. Which makes some drivers as my dad would use to call snake drivers. Where they weave in and out to get around the slow drivers on the left side. Traffic seems to be best when there are 3 lanes or more.
There are many reasons for slow-downs. THe vid just discussed one cause, despite the title. Poor lane discipline is always a problem.
Slow drivers are as much of a problem on the highway as speeding drivers. The problem is the speed differential, that's why it's so important to keep fast and slow traffic separated, but there are so many drivers who are oblivious to this fact. This is (another) area where public officials have failed us, they should be running 3-5 second PSA's instructing/reminding drivers that slow traffic needs to keep right! That simple thing would go a long way toward more efficient traffic flow.
Hey Mlong I have a challenge for you....
Next time you are on the highway stay in the right lane and drive a few miles slower then the car in front of you and do NOT attempt to pass anyone (maintaining a stopping distance of 3 - 4 seconds behind ALL vehicles in ALL lanes of traffic)
If you do this you will notice that all the vehicles passing you will go full speed right into the back end of a cluster of cars all tailgating each other in both lanes!!!
It doesn't matter how slow or fast the front car is going. The "slow car" most often is already driving over the posted speed limit.
I'd say I've noticed that about 90 to 95 percent of the drivers on the highway attempt to drive faster then the car in front of them at all times through aggressive tailgating and unsafe lane changes (squeezing between cars that are nearly next to each other in both lanes)
Traffic jams are caused by the vast majority of drivers on the highway trying to drive faster then the car in front of them, but nobody can drive faster then the car in front of them. Hence a traffic jam.
Anyone who attempts to drive faster then the car in front of them at some point MUST hit there brake or rearend the car in front of them or cut someone off in another lane, then that car they just cut off in the other lane MUST hit there brake to avoid rearending the car that just cut them off.
We need electronic signs hang across interstate Hwy to direct and remind driver must drive out side 740 when we have drive in front of their own lane. And also must cut back speed driving when driver or more drivers change lane and after must redo the distance 740 ft apart On the broke lane. We will tell in day time driving when we have more cities along Hwy the traffic will increase in cities and on the interstate if they must stop the vehicle or more vehicles for local must stop outside 15 ft and on interstate Hwy must out side 150ft. Any speed between 1 miles and post speed for local outside 150 ft and on interstate must out side 740 ft. If they violate we will find other way to help them earning and we will detention 1 month no driving. We will print monies to help workers jobs to fix problems failed to complying
Autonomous cars only drive the way the programmers think they should be driving.
I believe the "Tesla" autonomous driving system is probably a better driver as it probably drives with intent to reduce traffic congestion, increase fuel economy, and reduce wear-and-tear (as these cars are designed for "common" people) but I've had the experience of driving next to "autonomous commercial trucks" and they appear to be "heavily greedy" in their approach to "demanding the highway (road hogs)" and appear more optimized for "saving the truck's time" (as opposed to everyone's time or consideration for safety, or the wear-and-tear of "other" vehicles). Two different programmatic/algorithmic approaches to "how to drive" effectively.
In summary:
Tesla's approach is probably more like: "Many autonomous cars working together can save everyone's time and wear-and-tear"
Whereas these commercial autonomous trucks are more like: "Reducing OUR COMPANY'S shipping times is more important than everyone else, and we only care about our wear-and-tear"!
To the point where I've witnessed autonomous commercial trucks deliberately cut me off as I was about to pass it in the left lane (2-lane highway), only so that it could "practice it's merge algorithm" while simultaneously attempting to pass the other commercial truck at only 5mph faster. This of course forced me to slam on my brakes, as the truck and swiftly changed lanes in front of a vehicle, that the truck absolutely had to know was traveling about 20mph faster than it was (I know that the truck knew it too, because of all the sensors on that specific model/brand do in-fact check all traffic in 360 degrees for about a mile), inducing loss of mpg and wear-and-tear, on only my vehicle, but not the truck. Additionally, I had to wait about 10 minutes while it continued to attempt passing the other truck at what appeared to be quite literally the SLOWEST POSSIBLE speed differential, before I could continue on my way at normal highway speeds.
This was infuriating as we were effectively the only 3 vehicles on a long desert highway.
So these programmers/data-collectors/greedy-algorithm burned my time, money, and equipment, simply because it was a "free test case" FOR THEM to test a "merge maneuver" and simultaneous "overtaking" of another slow truck. And all they had to risk was "totaling someone else's car". Which I'm sure the algorithm was programmed to "accept the risk" since it would have been a rear-end collision, from their perspective.
I strongly believe that if it was using Tesla's algorithm, it would have decided to wait the additional 3 seconds it would have taken for my car to pass both trucks, before attempting its overtaking maneuver.
I strongly believe that these autonomous trucking algorithms are programmed to make UNSAFE lane changes in an attempt to arrive at its destination even 1 millisecond faster or even just to add 1 more test-case (1 more success, for the record) to the data-bank, so long as any risk of damage can be justified as "the other vehicle's fault". Because OUR ROBOT IS MORE IMPORTANT than ANY OF YOU COMMONERS! To hell with YOUR safety, YOUR time, YOUR money, and YOUR equipment.
It's almost like the autonomous trucking algorithm is designed to be an insurance-fraudster and road-hog. Because insurance-fraud is just another way to make more profit for the company. "*sarcasm* how can you call it insurance-fraud if it was done by a robot!? we have a billion data-points of a successful lane change! *end-sarcasm* 😛"... as if common drivers deliberately make lane changes just to tally-up "successes" for the sake of arguing "driving skill" in a lawsuit... Clearly a mountain of fraudulently collected "evidence" is hard to overcome if an autonomous truck forces a traffic accident.
Ironically, human truckers tend to be some of the safest, best drivers that I see on the road...
How to fix? Stop tailgating, give yourself a 200-400ft buffer from the car ahead of you. If you notice a car approach in the rear view mirror that is traveling faster than you, and there's nobody in the lane right from you, simply get over. The fact of the matter is, yes, traffic is annoying and we hate wasting our time driving in general, so maybe public transportation infrastructure would be a much better option, but it's also very VERY expensive to build it. To be quite frank, it shouldn't matter if you take your time, 40 seconds is not going to make a difference.
In my experience of driving long road trips, I find it useful to figure out my average speed in a jam. Even if the car ahead of me starts to gap further away from me, I only really accelerate close to not at all, because they end up slamming on the breaks. At first, yes it felt strange to be the one car that goes slow, but actually it's the coasting and balancing of the average speed and avoiding 'tapping the breaks' that get's traffic moving again. Try this, yeah? Give yourself a more than a semi-truck length in the traffic jam. This both allows for safe merging but also gives you more time to decide if you should stop the car. You may notice that the vehicle behind you copies you with about 2-3 car lengths. This happens when they understand that you're deliberately going slow to avoid slowing to a halt. Even when there is 400ft ahead of you going 15-35mph, don't accelerate, even if the car ahead of you does. Be gentle. Again, that is just something I do on road trips, results vary by state to be honest.
Just one more lane, bro...
Bingo! Drivers following too closely. Tailgating. Until the police and other law enforcement crack down on this, traffic jams will always be a problem.
Courts have to get in the program, cases are often thrown out of court.
The best way is to take drivers licences from idiots
The “hidden” cause? Stop putting overhead signs on the freeway that make people slow down to read them. “Accident ahead” is one thing, “suggested speed 40 mph” is unnecessary.
I see this all the time
Cause by people switching lanes like crqzy
Slow people in the fast lane need to *MOVE OVER*
Remember to coast instead of break whenever you can. Letting off the gas will slow your vehicle quite a bit. If you're leaving proper space between your car and the car in front of you then you can usually coast to slow instead of breaking and still have plenty of room for safety.
That IS one of the problems, so be quiet!! Drive and fill up spaces, do NOT just coast, that's the stupidest thing of all to do.
@@TheCommunicationCoach Not leaving space is the stupidest thing you can do, besides reproduce.

How’s this people learn how to actually drive and keep in their proper lanes
some genius should invent a way to move traffic jams underground
I think Elon already did... that goofy idea to build vacuum tubed subways.

Yeah, but it works too well so the government has to say "no " to that project. 🤔 Go figure.
@@billgreen1861 Actually... it is an overly costly boondoggle of an idea.

Trucks are the worst! I drive slow because of this: I am cheap, Plus its always your fault if you hit someone from behind, and I don't want to die.
***Please consider the audience and utilize appropriately skilled facilitators.***
This could have been explained so much easier/better by referring to; “intelligent cruise control”, which seems to buffer the “rail car effect” as a train starts and stops. I also found your description overly convoluted and seemingly unreasonable for the near future. I understand the interest of presenting in an unbiased way, but this seems to trigger doubters. Plus, do we really have time to wait for autonomous vehicles to solve traffic jams??? AND isn’t mass transit a form a synchronized movement of people? SAD!
Somebody alert the public, if you are using your brakes on the highway......... STOP IT!
Um ok next time a car on the highway brakes in front of you then swerve into the ditch or rearend them at full speed then if that's what you believe 😂
We are in a transition phase now where we can think and experiment what is best for the future. That things need to change is quite clear I think for everyone.
Managing traffic jams is not only about safe driving.
Traffic Jams produce about 80% (at least ) pm/ particle matter, so they are also very bad for the climate of course.
Something needs to be done and this pretty quickly.
Cars in Citys should really vanish into thin air . Slowly of course.
One should reduce the amount of cars in citys gradually.
I would only leave cars to people who need their vehicles for work like ambulance, fire, police, detectives, doctors, district nurses, mobile services etc.
All others are supposed to use public transport.
Pm is responsible for all kinds of illnesses which cost a huge amount of money: people getting ill, losing their jobs, needing treatment, needing social benefits.
And all because of traffic jams.
I was glad to hear that the best selling vehicle is not a car. It's the E bicycle.
How are you making about “climate change”
Sis you are blaming everything on cars ! Soon they will be solar cars with no fumes being emitted ! Only problem with solar cars is that the earth is being depleted of the vital nutrients it needs which are taken out of the earth to make solar powered homes , generators , cars !
I say we return to the beginning when cars were first started and all that was needed was water and a crank ! Also throughout the world Kia and other companies are destroying millions of trees daily and not replanting news trees ! The roots dry out and the land becomes barren and desert like ! Without those trees to protect the soils , the sun hits those lands the hardest and soon even the water dries out ! I say :
1. Stop cutting down trees because it’s killing millions of animals who are now homeless due to mankind’s greed ! Then they sadly die from thirst and starvation ! Most of these areas later become casinos or hotels or golf clubs ! Or the wood is used to build furniture and the trees not replace and the land and everything in it DIES !
2. Start building pipe lines that can reach all parts of the world that have no water or have water infested with germs and diseases like in Africa and India !
3. Destroy ALL cars and have everyone on bicycles again ! Horse and buggy’s too ! Why not ? The Amish ride horses and buggies and so do I !
4. People have to unite and rebel and force world leaders and corporations and pharmaceutical companies to STOP 🛑 with all the greed ! What is destroying this planet too are the people who waste the earth’s resources because they want 5 cars and up just to show them off and feel superior to other people like for example Jay Leno ! People don’t need 9 million dollars homes either ! For all the luxuries the rich have , part of the earth has been destroyed ! No one stops to think how the earth is being depleted and destroyed for its precious metals to build useless items for example Tesla cars or other fancy cars. ! The earth needs its minerals and metals but no one question nor cares ! The earth is dying and it’s freaking rotten governments and corporations fault !
DAMN IM PISSED 😡 ! Still , PEACE ☮️ ☮️☮️
All these thing and more are creating global warming ! PEACE ☮️

@@tenmiltenmil1770 I am not blaming everything on cars my dear, but cars are nevertheless a big issue, especially in big cities.
I was writing about the big cities above. One has public transport in the cities.
And we really need to be realistic for the future.
Your ideas about going back to the amish way are not realistic and this is not going to happen.
Humans need to evolve -it's in their contract.
there is no going back.
Producing solar cars doesn't change much.
The manufactoring of a car alone is already pure poison for the planet and this is without even have started using any kind of energy.
So in reality it doesn't matter at all what you use for your cars.
You need to reduce the amount of cars worldwide and the easiest way to do it is to take them out of the cities.
And try to do or think about one goal after the other.
Not everything at the same time.
It's just too much and you will get overwhelmed pretty quickly.
Start with the cars - this is the easiest part of it.
Basically, people can't drive.
These peoples they are the problems, drivers
I have said this all along that traffic jams are indeed started by a few boneheads either going to slow, speeding/lane splitting, tailgating or nowadays on their f..king cell phones. So many drivers are totally clueless to how their driving effects everyone behind them. A perfect example are the ones at intersections especially ones with traffic lights that don't give people room to turn right when there is room to turn right. Nothing infuriates me more to see one idiot with a line of people behind him/her with, their right turn signal as well, who are caught in a log jam because of one person🤬🤬🤬🤬 and, some do it on puroose as well Im sure. It goes back to the words of my drivers ed teacher how its everyone's responsibility to keep the flow of traffic going.....that unfortunately will never happen because you cant fix stupid and, there are those that enjoy being in controll of people behind them that enjoy being a jerk......my solution in my world anyway is to avoid driving at all cost when I can and stay away from the lunacy that for the most part driving has become.
And stop in blind spot and slow in blind spot.
