  • to save some folks a click:

    the phenomenon is called the "halo effect", and the opposite is also the case and called the "horns effect" (ugly people/things getting more negative judgement based on appearance).

    there's a LOT of research into these effects (for obvious reasons)...

  • wow, no.

    none of what you said is actually true.

    • "gridlock" happens in non-grid layouts too, the english name is just taken from american road patterns.
    • "show me..." no. YOU made a claim (that local information suffices, which is a VERY bold claim), so it's on you to prove that local information suffices.
    • roads are absolutely NOT "like wires"; they are like pipes. which is why civil engineers commonly use fluid dynamics to simulate traffic.
    • the rest of what you said is irrelevant to everything else.

    seriously, if you make a claim contradicting both the very premise of the post, and common knowledge on the topic, then at least provide a source for that claim, lr explain WHY you think your claim is true.

    "all the information is there" is not enough information to verify the claim; it's a wild guess without evidence to back it up.

    if shit where THAT simple, we'd have it figured out 50 years ago... it's almost like this isn't the simple problem you desperately want it to be...

  • this completely ignores larger traffic patterns like arterial roads.

    with your idea you are guaranteed to get massive gridlock all along the major roads.

    and biochemical assembly of proteins has just about nothing to do with either shop-floor-planning or traffic regulation.

    what you are suggesting IS better than simple timers!

    but it is NOT better than central coordination.

    you are seriously underestimating the complexity of the problem, and your "all you need to do..." bs only shows how little you understand of the underlying issues.

    do you really think nobody else has thought of what you're proposing?

    of course people have thought of this approach. it doesn't work.

  • how would that even work, if there's no indication that driving too fast was the reason for the red light?

    do these actually include some sort of screen that tells the driver they were too fast and that's why the light turned red?

    I'd imagine that this "feature" would only result in more frustration, and thus more speeding, instead of less.

  • I'm extremely sceptical about local data being enough to properly guide traffic...

    the problem is that intersections are connected.

    one intersection influences others down the line, wether that is by keeping back too much traffic, thereby unnecessarily restricting flow, or by letting too much traffic flow, thus creating blockages.

    you need a big picture approach, and you need historical data to estimate flow on any given day.

    neither can be done with local data.

    could you (slightly) improve traffic by using local traffic flow to determine signals? probably, sure.

    but in large systems, on metropolitan scales, that will inevitably lead to unforseen consequences that will probably probe impossible to solve with local solutions or will need to be handles by hard coded rules (think something like "on friday this light needs to be green for 30 sec and red for 15 sec, from 8-17h, except on holidays") which just introduces insane amounts of maintenance...

    source: i used to do analysis on factory shop-floor-planning, which involves simulation of mathematically identical problems.

    things like assembly of parts that are dependant on other parts, all of which have different assembly speeds and locations, thus travel times, throughout the process. it gets incredibly complex, incredibly quickly, but it's a lot of fun to solve, despite being math heavy! one exercise we did at uni, was re-creating the master's thesis of my professor, which was about finding the optimal locations for snow plow depots containing road salt for an entire province, so, yeah, traffic analysis is largely the same thing math-wise, with a bit of added complexity due to human behavior.

    i can say, with certainty, that the data of just the local situation at any given node is not sufficient to optimize the entire system.

    you are right about real-time data being important to account for things like construction. that is actually a problem, but has little to do with the local data approach you suggested and can't be solved by that local data approach either... it's actually (probably) easier to solve with the big data approach!

  • yes, true, but not exactly why i used the phrasing "wrong AND incomplete":

    i wrote it that way, because without clarifying that "destruction" means many different things apart form the common interpretation of "to kill", it's difficult for a casual reader to know what the convention actually says.

    if anyone wants to shorten the definition to fit into a dictionary, they should be more responsible in their phrasing, so that this exact problem is less likely to occur.

    so i do fault merriam webster here for providing an incomplete, oversimplified definition.

  • maybe read the actual convention on genocide instead of relying on a dictionary then?

    because the case of abducted children stated above is explicitly stated in the convention...the dictionary definition you found is simply wrong and incomplete.

  • this is exactly the entire plot of the Dark Profit Saga (Orconomics is the first book, 3 books total) and it's one of the best books I've ever read!

    it's written in a sorta Terry Pratchett-like style, with a modern twist, set in a typical medieval fantasy world, where the elites figure out that they can bet on the outcome of a dungeon raid in advance and invent a stock market based on the profits of raiding monster lairs!

    there's lots of plays on typical fantasy tropes it's also full of amazingly silly acronyms: the monster races are known as F.O.E.s (forces of evil), the "civilized monsters" are known as N.P.C. (non-combat c...i wanna say creatures? i forgot that one...) and tons more!

    it is glorious!

    highly recommended read for fantasy nerds!
