AI traffic light system could make traffic jams a distant memory. The system—the first of its kind—reads live camera footage and adapts the lights to compensate, keeping the traffic flowing and reducing congestion

  1. humans can literally cause a traffic jam on 6 lanes of perfectly straight highway with no intersections or ramps. I appreciate the deep machine learning trying to help, but we need some deep cranial learning where I live.

  2. There’s an intersection where I live. The whole right lane is a Tedder lane to a ramp. There is almost no cars competing with that lane turning yet it’s always backed up because people try and cut in front of everyone creating shockwaves holding everything up causing people to try and skip the line by cutting in front of everyone. It’s infuriating. I get even more angry at people that let people cut in.

  3. Gotto stop and stare at the car accident at the side of the road, possibly take some pictures.. leave the car to see what's going on before being told to move along.

  4. This is what I was thinking. Public transport, autonomous transport, and infrastructure built with non-motorized transportation in mind are the real answers to the traffic problems. And we have the ability to enact two of those right now. Countries around the world have been doing so for decades and it used to be the norm before cars became so prevalent.

  5. Exactly. Traffic is caused by acceleration times and merging. One dumbfudge on their phone lazily accelerating sends the entire bottleneck backwards

  6. No amount of AI can fix uncourteous and in attentive drivers. We really should stop giving anyone with a pulse a license in the US.

  7. Dude, you know perfectly well it's not their fault. If there's a bag of trash on the side of the highway, you're legally obligated to slow down to 5mph and stare at it while slowly passing by.

  8. True but some time its just suboptimal systems like north bound could be super busy but south bound almost empty and if there is a busy left hand turn on northbound side it has to wait its turn backing up even though its perfectly safe to turn because north and south light dont work independently of each other

  9. This is the reason why I am hopeful for full autopilot in vehicles. As much as I like to be in control behind the wheel I will gladly give it up if the stupid drivers do as well.

  10. I don't know what the title is for people who make the call on how lights are timed in my town are completely fucking worthless. Every intersection in town stays packed. There's no sequence. All you catch is back to back red lights. But quite often do to someone hitting a pole or lightning hitting something, we lose traffic lights for a good 10 blocks or so for a day. Those days are glorious. No traffic. Everything flows so smooth.

  11. The alternative is public transit that doesn’t suck, walkable cities, dedicated bike lanes, and roundabouts

  12. I don't think they were looking at all visible traffic as a whole and running the lights accordingly. They may have been using cameras to get an idea of when cars are queuing up in lanes. It's noticeable at many intersections in the city that I live in that approaching traffic can alter the light changing patterns but that only happens in light traffic. During the day they are strictly timed. This article is saying that the AI will be controlling the lights based off of traffic all the time instead of just altering the timing.

  13. Basic actuated signals (if car detected then stay green longer) have already been a thing. Machine learning based signals are new.

  14. In my area, the adaptive systems don’t work properly at a bunch of the intersections they’ve been installed at. Talking to more experienced people, they work as intended when you have teams of operators constantly updating the algorithm and monitoring the system.

  15. when I was a kid back in those days, I thought this was how traffic lights worked, but not automatically. I figured it must be someone's job to sit in, like, a building overlooking the intersection and just look at the traffic and operate the lights accordingly.

  16. Intersections know when there are cars queueing and stuff, but the rules for how long they're allowed to queue, how many cars are allowed to queue before reducing the waiting time to reduce congestion, which direction has priority and stuff all have to be set and manually optimized. The point of this AI system is to figure it out dynamically and automatically.

  17. This would easily be the kind of thing I'd already personally completed if I'd had the manpower and resources - been wanting to create a system like this for some time but could only really create it in a very small simulated environment.

  18. What we also need to do: is eliminate Stroads. The design layouts of the square block Street-Road with lights all over hell’s half-acre is a big part of the problem.

  19. It's funny because the Dutch allready have smart lights with just road sensors. But we all know which YT channel I learned that from .....

  20. “The program gets a 'reward' when it gets a car through a junction. Every time a car has to wait or there's a jam, there's a negative reward. There's actually no input from us; we simply control the reward system."

  21. The best thing for moving people would be to make sure that buses and trams always have green lights. If transit could beat traffic, more people would take it and traffic would get better from taking cars off the road.

  22. We have this in some cities (in the US) and it’s called “transit signal priority” where buses and trains get first pass through the intersection before cars. In the US it will typically have a separate signal like

  23. In Australia (ok, just Adelaide) we completely circumvent the issue by straight up giving busses their own road-track thing. It avoids traffic, creates less wear, and gets around people in the suburb being wankers who can't handle seeing a bus

  24. I used to work for a company that was contracted by the city and state of New York to create a "smart" traffic light system that did exactly this (except with sensors in the road surface since they're at every intersection anyways and don't require complicated AI systems to do the exact same job).

  25. I work for the Department of transportation and I can tell you that we are currently testing a AI system in California and so far the results are pretty impressive.

  26. And we were supposed to have full automous vehicles in like 2016. And now what we supposedly need is another traffic lane underground, and that will solve the problem.

  27. We have some sort of smart sensor systems almost everywhere here in the netherlands, also to accomodate for bike traffic etc. Roundabouts still seem overall better anywhere in towns. And congestion is still a thing. Just less bad.

  28. I don't doubt your story but everything involved here...cameras, computer vision, machine learning, algorithms, big data, cloud processing, etc have all made great strides in the last few years and there really seems to be the potential to actually move things forward.

  29. Wow it's like the simple proven version of this tech doesn't already exist in the Netherlands. Or anywhere else with not-stupid city planning

  30. Apparently my city thinks the only possible way is to have traffic lights every 20 feet, programmed for you to hit every single 5 minute long red light from destination to destination. There's a Starbucks 3 miles from me and it will take my full hour-long lunch break to drive there and back.

  31. My impulse is to say, "probably not at all or just very poorly", but if they're collecting data on pedestrian usage they could probably work that in.

  32. You can use the same camera system to monitor pedestrian volumes and adjust crossing time for them accordingly

  33. Wouldn't it still work the same way? There's a button at the intersection that overrides the algorithm to let the pedestrian pass.

  34. I dream of cities that have entire road networks underground. Hell, that would be an easy way to keep co² underground

  35. Trolley busses (with dedicated lanes) and better bike infrastructure are also great for reducing traffic and greenhouse gasses

  36. Trams with nearly permanent right of way. Seems to work in some parts of Europe, but without a concerted and sustained enforcement period, people here will not learn. Might not anyway. Take their DL with exponentially longer times per x violation points or whatever.

  37. Trains are fantastic, but they are far from the perfect solution. Cars are great for going to niche locations with a good amount of cargo. Trains also are massive single points of failure. If more trains were to be added, the higher the chance of delays and the higher the amount of people affected. This also could happen with cars but is way less severe.

  38. I have to drive 6 miles to work. There isn’t a train that goes from my house to work. We would need a lot of trains and tracks for everyone’s transportation needs. Then. Suddenly. We’d have traffic jams.

  39. Traffic will forever be a thing regardless of how many roads or how big roads are. Just going to be the case until there’s a different method of transportation

  40. If only there was a futuristic public transit system that used large connected cars that could hold multiple passengers and traveled a set route so traffic was a non issue.....

  41. Traffic can go away if the cars were synced and coordinated accordingly, so definitely not when people are driving, but might happen with autonomous cars. It has other pluses that can help like not having to look for close parking, just drops you and valet parking itself.

  42. "traffic" is people or cars moving on the road. "congestion" is slowdown associated with too much traffic. Traffic is a transit system working. Congestion is a transit system failing.

  43. They are spending a lot of effort on one temporary solution (using ai for better traffic flow), rather than installing transit options.

  44. No it couldn't. This title is misleading. It could reduce the occurrence and severity of traffic light related traffic jams, but that wouldn't be good enough clickbait to draw traffic to this shit website linked.

  45. Or how about…oh idk. We stop designing cities so that you have to use a car to be able to do anything? That way traffic won’t really be a problem.

  46. Until we are able to prevent people from being assholes on the road, I don’t expect too much of a change. I almost got into an accident just this morning! I was on a highway and saw a semi was going to need space to merge, so I put on my blinker. There was only one car in the lane I was trying to get over to and the driver kept looking over and wouldn’t speed up or slow down to let me in! The semi merged and I had nowhere to go, so I had to drive down the middle of a two lane highway! Thankfully, I was able to avert the accident, but it was a very close call. I don’t mind driving, but I’ve noticed an uptick of people going out of their way to be assholes on the road lately, and it makes driving much more nerve wracking than it needs to be. Anyway, sorry for the rant. I’m still a little shaken up.

  47. This already basically exists.... they've been using ai motion tracking and object identification on camera feeds along with standard traffic loop input to control traffic in real time for years. It's in every intersection in my city. What's novel here?

  48. Unpopular opinion - keeping the traffic moving isn't a good thing. It means more journeys are done by car instead of public transport, cycling and walking, and there's loads of knock on adverse impacts as a result. The emphasis in transport management and planning should be on making sure people can get around without using cars. The US, mostly, is stuck in the dark ages on this though.

  49. Why is everyone hating on this?? The amount of time I've been stuck at traffic lights waiting for non existent cars is baffling, could really use this in sydney Australia

  50. Because spending time and money solving for your lost 2 minutes is not valuable when we have much, much larger transit fish to fry.

  51. So Sydney Australia uses something called SCATS that’s kind of like this but not as advanced. There are places in the US that are trying to transition to all SCATS signals which are run by AI. And they have at least 4 cameras that look at each approach and monitor for vehicles at the stop bar.

  52. Hasn't this tech been around for a long time? just maybe with regular programming rather than AI?

  53. So what you’re saying is, that one light that ALWAYS changes red 20ft down the road will now be green?!?! I’m all in.

  54. We have something similar in Israel already, and let me tell you, if the capacity of the intersection is lower than the amount of cars there is gonna be a long fucking jam no matter how the lights change.

  55. They changed a light by my house from sensor to timer. There are few things more annoying than having to sit at a light for over a minute without any traffic coming the other way the entire time.

  56. Cool concept, but aren’t most traffic jams caused by driver variability? Where I live people love to ride their brakes down a hill or through a tunnel causing severe back ups. You also get the asshole who cuts over to an exit ramp only to cut back into traffic causing people to hit their brakes.

  57. I think the lights in my city are timed for maximum inefficiency. It's a small city and traffic is constantly backed up, blocking an intersection. The lights turn green just in time to catch the light at the next block turning red. All the residents here probably burn twice the amount of fuel. I always wonder if this is by design or by incompetence.

  58. IIRC the real cause for traffic jams (aside from emergency bottlenecks like accidents) was tailgating. I’m not convinced AI traffic lights would prevent that.

  59. Long queues at traffic lights could be a thing of the past, thanks to a new artificial intelligence system developed by Aston University researchers.

  60. It's a good thing computers never make mistakes and machine learning never comes up with unexpected results, ever. :) /s

  61. Every street and crossing has a physical limit how much traffic can be pushed through it. No AI can change that. It will reduce congestion, but not will not make traffic jams a distant past.

  62. This would be terrible news for Calgary Alberta. They deliberately make it hard for cars to get around. This is an incentive for people to use mass transit. Less cars on the road, means less congestion.

  63. Or we could replace traffic lights with roundabouts and accomplish the same thing with probably a lower cost and no electricity. Plus the Roundabout can have greenery on it for carbon capture.

  64. This is neither the future, nor a solution. There will always be traffic as long as there are too many cars and not enough bikes, trams, buses, subways

  65. NO. The only way to reduce traffic is public transportation and person-centric city planning. Stop building cities around cars.

  66. It won't happen. Cities would rather give money to cops to shoot poor people than to buy the equipment it would take for this to happen.

  67. With cars able to drive themselves traffic signals would become useless. In fact almost all traffic offense concerning a person driving a car would be obsolete! Yet, the police and politicians aren’t looking to change anything, to much money is invested and made from traffic court!!

  68. Dude, with AI and smart vehicles, all plugged into the grid, if you will, there would be no need to traffic lights. Cars would talk and think so that they’d compensate to maintain fastest travel time& safety. Always going to be those road hazards tho. Snow, ice, down trees. What about in rural areas with constant big brother looking out, I know not many lights but what about in 20 minutes when I’m back in the city…? To totally insane to think about? What about cars being rugged by semis acting as a train or automation/AI for that.! Dang.!

  69. This can help in some cases but as someone who has driven the 95 corridor regularly and the 5/405 I’ve gotta say our biggest issue isn’t with lights…

  70. It ignores that principle that a lot of traffic lights are designed to make vehicles slow down. A lot of traffic light sequencing is specifically timed to make vehicles stop even of there are no cars around. There are also other considerations to factor in on mentioned by a lot of other people.

  71. Except for literally anyone else moving about in not a car. How do pedestrians, bike rikers, motorcycles, etc. fit into this equation?

  72. How about instead of using AI to optimize a fundamentally inefficient use of space, we use AI to enable smarter buses that can take people where they need to go without using cars, which will free up space for mass transit, lower emissions, higher density, and more walkable cities?

  73. Nope not a chance. If you remove humans from driving. Of course. Arseholes in cars are what causes traffic.

  74. People are still going to be idiots and run red lights. Even AI can’t really stop people from being dumbasses.

  75. Two items will undoubtedly solve the traffic congestion issues and only these two. Nothing else.

  76. I don't know why we don't already have this. Seems like something we could have been doing already for at least a decade.

  77. Was reading about this, it redirects bad drivers and elderly off the main path to make room for more competent drivers. It also sends everyone over 65 to a class to get audited on their ability to see if they still remember things like which lane on the freeway is the driving lane and which lane is the passing lane.

  78. I feel like this exists already in Stockholm. Especially at night the lights always change just before you'd have to start braking it's great. Always plenty of time to stop before a red too.

  79. Of all the things you could try to reduce traffic like building more public transport why is the first the government tried a national surveillance network.
