    I have to say that after just getting back from Japan that they do have a certain affection for the whimsy even on large scale publicly funded projects that is just awesome. One of the things I saw was a huge platform with a glass top and water on top that served nothing more than a spaceship like cover for a courtyard down below and an attraction. Pics here [utah.edu].

    I would have loved to have traveled on these roads while I was there...

      That platform is in Nagoya. It's called the "Area 21". The glass "pool" on the top collects rain water to nourish the grass areas around the area.

      The area beneath is used for a lot of purposes, from concerts to street soccer championships.

      Nagoya (and Japan) has a huge number of projects with the sole purpose of making the city life more fun and less stressful. Like the lamp posts playing smooth jazz in the evenings, or the carousel attached to a building close to Area 21.

      There are virtually no street vandalism, so they can put a lot of statues and art on the streets, and it stays untouched and unharmed.

      Of course it's not heaven on earth, there are problems, but in the lat 2 years it became my most favorite city.

      I lived in many places, Midwest, west coast, east coast, europe, singapore, new zealand, but so far, the city life in Japan is the best I have ever experienced.
  • In Massachusetts, they are continually working on roads... I'd love to know the secret that makes them think that they'll be able to keep these strips around for more than a year or so. Beyond that, I'd think that it places greater stresses on the outermost pieces of tire, because of the uneven loading. Doesn't seem that smart to me...

      Forget tire wear. What about the uneven coefficient of friction? That can get you killed. Predictability of your vehicle's reaction in all situations -- especial in emergencies -- is important.

      Maybe they're not built by the lowest bidder?

      I remember an interview with the chief engineer of a road construction company. He claimed that if the state was willing to pay about twice as much, he could build them a road which could last 100 years. But if he did that he'd be underbid for every contract and would go out of business. So the state ends up with roads which need to be resurfaced after 5 years and rebuilt after 15-25. Essentially the longevity is enough to span one politician's career in that office. After that it'll be someone else's problem, so why spend extra money on it?

        Out in California you get a chance to see and feel the various levels of road quality that very nicely prove your point. Up in the Sierras, I-80 is concrete due to the winter conditions and chains. Wonderful to drive on any time of year. Down in Sacramento, and around the Bay Area, the freeways are often asphalt (asphalt concrete, not mastic asphalt) over dirt, baby. Great if a little slippery when it's brand new, just adequate when it's mature and really bad when it's still five years out from being replaced. At the local street level all the money from the boom years has been spent so it s gravel-over-tar every five years. Cars go through windshields at an alarming rate, but hey it was the cheapest bid. Interestingly, the decreasing level of quality is also mirrored in the reduced level of traction, so not only are better roads nicer to drive on, they're safer, too.

        I'm afraid this is what happens when there just isn't enough cash to go around. The amount the States get from the Federal taxes in various forms is reduced and so local infrastructure expenditures drop. However, it's not like the Federal government is spending more than it takes in on something that benefits only a select few and has quietly hidden the true costs here and there. There is a war going on; how can we complain about the state of our roads when on the other side of the world there are roads actually getting blown up daily? We have to rebuild those first, along with the electrical distribution, water supplies, schools and hospitals...the list goes on and we haven't even started. Once we have rebuilt Iraq in our image, then and only then can we talk about fixing things here with a clean conscience.

          I'm told by someone who works in Oklahoma's DOT that the tension between concrete and asphalt roads is this:

          Asphalt roads are pushed by human-factors people because they're softer and less fatiguing to drive on. Obviously this is more a factor with highways. Concrete roads are pushed by engineers because they last longer. However, they're a pain to resurface because great chunks must be pulled up ('crete is laid in large rectangles), while with asphalt you can just pull up the bits that need to be redone

    It's my understanding that the rougher the road surface you drive on, the faster it wears out your tires. Not just a small amount either, I seem to recall reading that it could shorten the life span of your tires by 50%.

    I don't know about anyone else, but I think tires are expensive and hate spending money on them. I would not enjoy having them wear out quickly so that I can listen to the same damned song every day on my way to work... The radio already does that for me, and it doesn't ruin my tires.

    Saw this on Top Gear (on Discovery Channel) a couple of years back. Not sure if it was Japan, I think it was a European country. I think they used bumps though instead, so that at certain sustained speeds it would play a nice melody but if you went too fast it would sound horrible and scarring.

      There's one in the outskirts of Paris near Villepinte. The idea is that if you drive the correct speed you hear a melody but too fast and it's just noisy. I can't say it works that well (at least I had no idea what the tune was supposed to be - maybe it was some French classic) but cars did seem to slow down on the bumps to try it out it seems to be reasonable at traffic calming...

    Years ago the Walt Disney World was looking for additional magical things to add to the roads for their upcoming Millennium Celebration. On a desolate piece of road on property speed warning indicators were tested (the kind you encounter on the side of the road or before a toll road) that played a song. That song was "Zip A Dee Do Dah", and for years it stayed there. There were problems with it. First, was the fact in order for it to work, you would have to be driving a VERY specific speed, not faster, not slower, or it would seem like a random assortment of rumbles. And when someone would go the wrong speed, they'd think there was something wrong (veering of the road, toll soon, etc), and would try to break, get the car back on the road, etc, that it became dangerous. Since it was dangerous, no one would drive the correct speed, and the fact they'd need to tear up the roads just to install it, Disney mothballed the idea.

    Anyway, my idea came from the speed warnings in the road driving up to the airport in Dallas: about fifty 1cm ruts, perpendicular to the direction of traffic, caused a loud noise and strong vibration in the car. I thought, "If this can make noise, why not speech?" And the faster you went, the louder, more high pitched, and more strident the voice would be. It could say,

    In Montreal a generation of Metro subway cars electric motors [wikipedia.org] were tuned to perfect fifths, coincidentally the first three notes of Aaron Copland's "Fanfare for the Common Man". The tones were even part of a TV ad campaign [youtube.com] when the line was opened.

    However the Montreal Metro offers another treat to the senses: Smell.
