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

Posted by msmash from the shape-of-things-to-come dept.
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.

    * 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 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.

    • 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.

        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.

    • 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.

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.
