Comment Re: Are there people in the government (Score 2) 54

If you think a private industry consortium will.have more your interests at heart than your own democratically elected government... boy, do I have a bridge to sell you.

Also, if you're realy that gullible and still somehow old enough to have learned how to read, you deserve whatever comes your way from a dysfunctional government or industry.

I owned a sim card until run recently that had bought sometime around 2009, and that had a fake name. And I didn't go out of my way to buy it, I just ordered it and supplied a fake name when they asked for it.

I also activated several short-time sim cards whule on holiday 2010-ish, also with fake names.

So... nope. Not 1998.

The capacity peak isn't at 25 mph, it's somewhere aroubd 70.

This is because the metric for "capacity" is not how densely you can pack the cars together, it is how many cars can you get across a unit of distance in a given time. And a parking lot full of cars is going nowhere, so it's "traffic capacity" metric is very, very low.

That's just a first order approximation.

The closer the highway gets to "full" capacity (or even overcapacity), effects like "dawdling around" and the resulting oscillations in flow play an increasingly important role. And this already happens when essentially all drivers are at "moderate speeds", albeit slightly different ones.

Stuff just eventually breaks, even without assholes, once you approach full capacity. (Speeding assholes wouldn't even exist on a too crowded highway - therr simply isn't anywhere to go when everything is full. This is true even for German "autobahns", where speed limits are often nonexistent. You can rest assured it's even more trurle in the US.)

I'm.guessing one solution would be orchestrated, fully automated vehicle control. There the low latency would pretty much eliminate dawdling, in addition to increasing capacity by packing cars closer together (you don't need as much safety distance when you can reliably exclude requiring the "moment of shock", and brakes are veing applied at millisecond accuracy by a system that knows that 10 cars ahead of you someone needs to break right now.)

But this is way, waaay beyond just sensoring up the higway and dynamically adjusting speed limits.

Some states in Europe, e.g. Germany, have been doing similar things for decades.

It does improve flow, ultimately difficult to say by how much. But it's not magic. Probably coupled with a ruthless and stupidly expensive camera based speeding system (i.e. $100 for every 1 mph above the designated flow speed) might work, but otherwise the bottleneck will be slight speeding. It will return laminar flow to oscillatory flow (break & accelerate), then to stop & go pretty soon.

A full highway is a full highway, there's little in the way of magic or capacity to remedy that.
