Audi Cars Now Talk To Stop Lights In Vegas (ieee.org) 105

Audi says its cars can now tell drivers how many seconds remain until the traffic light turns green. It's the first commercial offering of vehicle-to-infrastructure communication in the United States, it adds. From a report, submitted by an anonymous reader: Of course, nobody would pay much extra for an electronic gadget that just lowered your stoplight waiting anxiety. But this feature is just testing the waters; bigger applications are in view. The cars -- recently manufactured Audi A4 and Q7 models signed onto Audi's prime connection service -- communicate with the Las Vegas traffic management system via 4G LTE, the standard mobile phones use. The countdown appears on the dashboard or heads-up display, then shuts off a few seconds before the light changes (presumably to keep drivers from getting mesmerized). Audi manages the transfer of data with the help of its partner, Traffic Technology Services (TTS), of Beaverton, Ore. The plan is to eventually give drivers the information they need to make fairly ambitious predictions, like choosing the right speed to go sailiing through several green lights in a row. Or the system might bypass the driver and go straight to the engine's "start-stop" system, shutting it down for a long count, then starting it up again seconds before getting a green light.

      My biggest concern is...

      How do you turn this car-to-anything-external comunication the fuck OFF?!?!?

      Geez, I mean, I don't want this crap on my car, to aid in tracking etc.

      Hell, its difficult enough to disable OnStar or any other myriad of car to base communications as it is....this sounds like even more potentially intrusive software/hardware reporting to authorities on the road.

      Hell...I guess I am going to just stick to in the future...70's muscle cars, and other older 'fun' cars to ride in, without all this crap.

      Hell, I'd pay EXTRA on a new car to get it without all this external to car communication.

        I'm on the market for a new SUV and one of the features that I demand is that it does not have a cellular modem. The 2016 Jeep Grand Cherokee has one in the head unit. You can disconnect the cellular antenna but it will nag you about it every time you start it. You can buy a dummy antenna, which will stop the nags, but it will still manage to connect to the cell towers at a slower speed.

          My take from the summary is that the car is talking over 4G to the company controlling the lights, and getting the counts from them. So you'd need to worry about some kid hacking the company and messing with all connected cars, not some kid on a corner messing with one.

It will probably take the path of forcing anyone who has a non-networked vehicle to get a "vintage" registration that limits the annual mileage.

    Dear car makers,

    Instead of pushing useless gadget that nobody cares about, what about trying to develop affordable hybrid and electric vehicles? Right now, buying a hybrid mid-range car costs as much as buying a luxury car, which nobody sane would ever do. So please, focus on affordable green cars instead of bullshit toys.

      Nope. The traffic light still waits all the same for every one.
      The only difference is that the driver of the luxury car gets the privilege of having the wating counter of the traffic light directly displayed on their dashboard.
      (And the car will be able to shut down and restart the engine during the wait on its own if it is economic to do so).

    * If there is no car in front of me I still have to wait for the light to turn green (and then some in the US to avoid red light runners)
    * If there is a car ahead of me I still have to wait for them to move before I can move.
    * If I have a car that shuts the engine down when stopped (and I have driven such cars), the engine already instantly comes on when my foot lifts from the brake pedal (and if it doesn't it won't happen with the App either)
    * If you are driving in traffic you still can't beat the dynamics of all those other people (and traffic doesn't /can't act like plug flow in a pipe unless you build in major automated convoy support)
    * If it is just you on a main road then it tries to keep the traffic flowing by defaulting to green lights in your direction (and it's those pesky side road drivers who screw up your green lights)
    * If it is just you on a side road then the lights will be defaulted against you anyway.

    So what are they really trying to solve? They already have a bunch of sensors/cameras that can be used to sample traffic and tell you what the current traffic patterns are.

    • They are trying to solve the lonely life of your Audi, which has no dates, and is trying its pick-up lines w/ the traffic signals. Would have a harem all over the city. Of course, what about all the Hondas, Toyotas, Fords, Chevies et al that are on the road? Don't ask
    • Even more importantly: In America, the stoplights have "hoods" on them to prevent them from being seen from any angle other than head on. They used to use a shiny substance but in direct sunlight, you could not tell if the light was green or red, so they stopped that. Regardless, the intent was to keep drivers from knowing what the other light was to prevent people from going into the intersection when the cross traffic had a yellow that was about to turn red. This violates that.

      • In America, the stoplights have "hoods" on them to prevent them from being seen from any angle other than head on.

        Is that what those hoods are for? I always thought they were to make the lights more visible by keeping them out of direct sunlight. Most of them certainly aren't very effective at hiding the color of the lights facing the other direction, whether because the angle is wrong to block the entire light or due to more subtle reflections, often on the inside of the hood itself.

        In any case, hiding information about the status of the intersection is counter-productive to ensuring safe and orderly traffic patterns.

      Best I can figure is they want to eliminate any delay between the light turning green and the Audi driver leaning on the horn to let the person in front of them know that it's time to go.

    • At a guess, if you have a known quantity of red light time, you can tune the radio, adjust your seat, etc, and not get caught out when light goes green. This should lead to lower frustration levels for both you, and the cars around you.

      For a car manufacturer who trades solely on the "experience" (let's face it, Audis are just over-priced VWs), you can hardly blame them for trying something like this.

    • No, the Audi can smell the Volkswagon next to it and tell it, "Get away from me.... You stink!!!"
  • I would like to see the countdown until the light is red, and if I'll make it at my current speed. This could help to save gas, as drivers could reduce acceleration sooner. Of course someone would soon hack this to tell you how fast you need to go to make the green (or yellow) light...

    • Yeah... the only thing is, if the light is still green but the countdown timer clearly shows you that you won't make it how likely are you to actually apply the brakes?

      There is a road near where I live which has a 65mph speed limit (which means people do 70 - 85) but has several stop lights. Since that is too high a speed to slow in time on a normally timed street light, they put up these flashing amber lights which will come on 5 seconds or so before the light turns yellow. So you know very well that even

        You are correct, anytime where you aren't bothering to look at where your vehicle is heading could lead to disaster.
        looking up at the road then back down again - (at what?) - just seems like poor driver behaviour.

        Saw this recently in person, when an emergency vehicle with just flashing lights - no siren - was turning across an intersection in front of me. I could tell traffic was moving strangely and slowed down, then stopped when I saw the emergency vehicle - as did the car next to me. Unfortunately the

    • Look at the pedestrian crossing signal. If it's signalling walk then you have plenty of time. If it's flashing don't walk then be prepared to stop. Some of the newer signals have a countdown on the pedestrian crossing until the light change and that will tell you exactly how much time is left.

      Most people would use this to speed up to make the light instead of slowing down. And this actually exists as this is the purpose of the yellow (amber) light.

    The reason why the stoplights for perpendicular traffic lanes have "blinders" on them is because people's reaction to the light switching colors is a consideration of the time on Yellow Lights.

    If you have some drivers with Asymmetric information advantage: the yellow light times will be based on the general public's behavior, and a subset of that public will start moving into the intersection earlier due to the lack of surprise improving their reaction time to the light switch.

  • Stop lights in the Philippines have large LED readouts next to them which count down the time to turn.

    Seems to work well. People behave themselves and don't generally do stupid things.

  • If someone is so anxious about the red light turning green that they need a countdown to ease the anxiety then I'm thinking the problem isn't that a countdown is missing in their life. Why are they in such a state so that they are anxious about the light turning in the first place? There are a few cases where I could see a reason for being anxious such as being late for a job interview or wedding. But if you are anxious at every red light that you come to then I'm thinking that what you really need isn't
