back to article Hackers create 'ghost' traffic jam to confound smart traffic systems

How many “adversarial vehicles” do you need to befuddle smart traffic lights? Just one, according to research published in late February. Five researchers from the University of Michigan attacked the traffic control system the US Department of Transportation has been using for trials since 2016. Called I-SIG (Intelligent …

    This is why we need AI so badly - to distinguish the good from the bad guys.

      And, as the next step, arm them with large-calibre guns firing DU ammunition. I can't conceive of any situation where that could go wrong!

    A Half-Minute Jaunt Could Be Dragged Out To A Stunning 14 Minutes, You Say

    In case any UK readers think this is excessive, North American train lengths can be measured in miles / kilometres.

    Canadian road traffic law governs the obstruction of roads at level crossings, by trains, to a maximum of something in the order of 11 minutes.

    Long enough to pop out to pick up a coffee and a donut at the nearby Tim Hortons!

    Hackable sensors not really necessary...

    When I was first in Czechoslovakia (it was still Communist then, so before 1989), I noticed that some towns had illuminated speed indicators/signs mounted on poles or street lights at the side of the road. These looked a bit like the speed warning signs we now have (in the UK), but instead of flashing up your speed as a warning, they flashed up the speed you needed to drive at in order to get through the next set of lights on green.

    They weren't at every set of lights and, iirc, on the main road of the junction, but they did help because even though you could see that the lights ahead were red, you knew you wouldn't be held up so no need to engine brake, or gently slow down trying to avoid actually coming to a stop.

      Quite common in a fair part of continental Europe, on larger roads in/through a city. One light has a green wave signalling, indeed, a green wave, a second has the advised speed. Some even have a third light with a lower indicated speed for the case that the lights at the next crossing are still red but will turn green any moment now, and slowing down a bit will let you catch the wave

    Try any of this where i live

    And the cross traffic only considers the red to be advisory in nature.
