Mandalay posted:aside, those numbers seem pretty bullshit If you're talking about the costs associated with accidents, those are quite solid. My internet's going at a crawl now, so I grabbed the first source I could find from the FHWA, and: code:
Rumble strips cost 24 cents per foot to install. That's $1300/mile, and they last as long as the pavement, say ten years. Anyone who lives near rumble strips will tell you they get run over several times a day. If even one of those in that ten year period wakes someone up and prevents a single-vehicle accident, you're averting at least several thousand dollars in car damage and, more likely, an injury.

Out of curiosity, those are costs to whom? The state, the drivers involved, insurance companies? If it's the state, I'd assume it's via some sort of liability theory or simply the legal costs of defending a suit?

Arcturas posted:Out of curiosity, those are costs to whom? The state, the drivers involved, insurance companies? Hence these sort of figures include all costs on the state economy. The medical expenses imposed on the insurer or injured person and the vehicle repairs are a net loss to the economy because they're broken window exchanges. Resources used to patch up cars and people could be used somewhere else in a manner that resulted in greater satisfaction to the general populace, so utility is lost in accidents. In addition, the productivity of people involved in accidents is usually decreased to a varying degree, which also results in an opportunity cost. The configuration of payers isn't important in the calculation. What matters is how much are we willing (and able) to pony up to keep people alive and uninjured. In other places, that's not a lot of money.

Or any basic common sense by its users. I almost ran over an idiot skateboarder the other day, who was wearing all black and skating in the middle of the road at midnight on a Saturday. loving moron would have deserved it. I yelled at him to get the gently caress out of the road and he started laughing at me - laughing at me - and yelled back that "the roads are for everyone, duuu-uuude!" It was about that time I considered circling the block and giving him another pass. Maybe just pop him with my mirror... These are the fantasies I have.

People have no idea how invisible they are on roads at night, even well lit roads. Unless you're wearing reflective safety poo poo, you are invisible. The worst is when someone wearing black, at night, illegally crossing the street at a blind corner or something sees you coming, then just goes back to slowly crossing. loving SCOOT, move!

Chaos Motor posted:Or any basic common sense by its users. Indian traffic is just a powerful example of game theory. In the absence of enforcement, breaking the traffic rules gets you where you want to be quicker and cheaper than following the rules, regardless of what other people chose to do. It's therefore said to be a dominant strategy. Hence everyone will start breaking the rules until you end up with what you saw in that clip. It's obvious that it's not a Pareto-optimal situation since the traffic devolves into chaos, but that's why we've allowed the government to allocate a good deal of resources to enforcement of traffic rules in most western countries. India's highways are a place of anarchic libertarianism, not because Indians are stupid, but because the Indian government has more pressing priorities than enforcing traffic laws and improving highways.

If someone posted a video of Saudis "sandal skating" around the ring road of Riyadh, and I said that was lacking in common sense, would I now be 'racist' against Saudis? What if I include the link my buddy Ahmed of Jerrah sent me where he said that it's "stupid" and "dangerous" but lots of Saudi teens do it? Think about that for a while.

I'm told by a friend who comes from Bangalore that most drivers in India obtain driver's licenses by sending a brown envelope to the next state and getting a driver's license in return mail, so obviously driver's education has plenty of room for improvement. But it's been demonstrated several times that even professionals need constant reminders that you shouldn't muck about on the road all nilly-willy.

For those who wanted to see what it looks like when I stick vehicles in this: I gave it a shot. Cars head out in 4 directions from the central intersection (the one with the buildings), at a rate of 10,000 per hour per link. The whole network got progressively jammed up, as expected, since there's really nowhere for them to go. After 3600 seconds (1 hour), there were 8400 cars in the network. Here's a quick show of it. https://www.youtube.com/watch?v=XILoSeGUmnQ There was originally sound, too, but no video site would accept that version for some reason. So there you have it, Goonville. Sorry I couldn't get more footage, but I had quite a bit of work to do today, and to email all the .AVIs home, they had to be in <5MB segments.

Alright, here's my challenge. From Lynn, MA: Google Maps When turning left from Essex St onto Central Ave, the small turn you make is signalized, with a sign instructing you to turn left on red. I have never seen such a thing elsewhere. Fun fact: See Brothers Deli in the bottom right? It's one of several Brothers in Massachusetts, all both similar and completely unrelated except by name. Not bad for greasy spoon fare.

I moved to go back to school, to what's pretty much a college town. 113k people in the city itself. However, using I-35E is an absolute nightmare. It's 2 lanes each way in most of the city, with suicide on/off ramps. You get all of a couple of hundred feet to get up to highway speed while going around a ramp with sharp (for those speeds) curves; likewise for exiting. The worst is the exit by the mall. Pretty much whenever the sun is up, the southbound exit ramp is backed up all the way to the highway. They recently redesigned the road to be 6 lanes total (used to be 2), but getting NE of the highway (or working your way back) is an absolute nightmare. It's bumper to bumper from about noon to 7pm around there. Here's a Google Maps image of the area. Most people on the exit ramp leave enough room for people that are going for the u-turn lane; a lot of people (myself included) do a u-turn and cut over to Colorado Blvd to bypass most of it. What could be done to improve traffic flow? Most of the traffic from 35 south is trying to go NE, and vice versa. (click for big)

It happens quite a bit in Boston, as you might expect with all the one-way streets. Can someone from outside MA comment? Same in CA, but at least around here half the people don't seem to know it. There's only one intersection of two one-ways in town (that I can think of, anyway) and I'm constantly getting stuck behind some idiot who is just waiting for the light to turn green. That goes double for the outer/rightmost left turn lane (there are two). Lots of people don't seem to understand you can turn right on red from ANY dedicated right turn lane, and combining that with left on red would probably make their heads explode if they thought about it.

Left turn at a one way to a one way (right direction, of course) is fine here in Ontario, too. I freaked out my buddy doing this a while back. We're from a relatively small town in rural Northern Ontario (150k, the biggest city in Northern Ontario), and he'd never come across it. Hell, we only have like 4 one ways in the whole city.

It's one of the trick questions they give you on the driver's tests. It sure gets you to remember it, oddly enough. You can turn right on red so long as there's no sign disallowing it (or in one other special case that's escaping me at the moment).
