I counter your study with another study. This is still a heavily studied topic, and results seem to vary depending on where, who and when the studies happen. The benefits seem to be negligible when compared to a properly designed yellow phase, though.
offtopic: Here's a link to a page on w3schools, briefly discussing anchors.
Not this:
1. Such a system would probably be a maintenance nightmare.
2. There are already too many signs providing information at urban intersections. Too many engineers insists on providing every tidbit.
3. I'm not sure that you understand how big lettering actually is for a road with a design speed of 45 mph. (I took a look at my sign design book, and for this instance, assuming that we treat it like a regulatory sign, we would want those digits to be 10" tall. Guide signs that use primarily symbols have an icon as tall as 24".) Even monochrome LED displays of this size would be prohibitive when you multiply that by the number of intersections even in a place like Anchorage.
4. It would be a moving thing that would distract drivers from other essential information at an intersections. We are, at basic, a hunting (as well as hunted) animal. Things that move within our vision grab our attention very quickly, without training to the contrary.
5. Signal controllers are extremely slow-moving designs. Like telecommunications equipment, they are heavily tested before they're deployed. Signal timing is complex and the safety considerations are, of course, huge.
6. Behavior. Even generally law-abiding drivers will likely find themselves speeding up to clear an intersection if there were such a clear indication of how long is left. What happens when the driver, who is now going faster, finds that she won't clear the intersection. Your safety problem just got worse.
Sorry, but I've heard this suggestion before, and it makes me shudder. Longer, well-design yellow phases, are proven effective in reducing overall crash rates, rather than one kind of crash as with red light cameras.
Signalized intersection often (it probably depends on local design standards) include a very short clearance interval to account (among other things) for these drivers. The clearance interval is a short period when everybody has a red light. The real problem is when several cars do it at once.
huh. I've been paying for DNS registration and a dynamic account through them for so long that I hadn't noticed the change. The only annoyance that had any affect on me was when I changed from a static to dynamic DNS with one of my three ISPs.
Right now, my wife (plus two kids) and I live in two different locales. I recently switched her ISP to a faster service, but have to overlap the service while she updates e-mail addresses with her various e-mail accounts. I had trouble when I wanted the former static address to update dynamically, but once I understood that this (with the paid service) happened on the client side, I was a happy camper. I would have been happy sooner if they gave explicit instruction for this, but it all worked out for me in the end.
In California, we had a recent series of of federal raids against medical marijuana growers and sellers that were legal by state standards (they went after the most clearly legal and above board operations first).
President Obama, while he was campaigning, promised that this wouldn't happen. I didn't vote for him, but did hold out hope that he would be better on civil rights than our last president. It's a shame that they're about the same.
Could Google? I was thinking about Apple wanting to build out it's own network of sorts, then thinking about Apple being able to control the experience from top to bottom. A few minutes on Google and I find that T-mobile is worth about $11 Billion, and Google has about $37 Billion on hand. When you also consider that Google has flirted with providing wifi in cities, and is rolling out a fiber network in Kansas City, it makes an odd kind of sense that they might want a cellular network, too.
After the text is selected, you expand the area of the text with the two little arrows on the top and bottom of the text box. In order to move around (presumably so that you can select more text) you lift your finger, then drag the screen as you would normally. After you've moved (closer to) where you need to be, drag the little arrow again. You can also zoom while you're selecting text.
My credit union has cooperative agreements with other credit unions. I'll grant that this doesn't come with the ubiquity of Wells Fargo, but I really don't have any complaints or any problems when I travel.
Spain also became quite hostile to non-catholics after a fashion. Further, that "Golden age" was not only in Spain, but in northern Africa as well. Jews had to pay a special tax to muslim rulers, and in some parts of the middle east were slaves to muslims. While both cultures flourished, one clearly saw itself as superior to the other. Further, it wasn't all that great for the jews:
My heart is in the east, and I in the uttermost west--
How can I find savour in food? How shall it be sweet to me?
How shall I render my vows and my bonds, while yet
Zion lieth beneath the fetter of Edom, and I in Arab chains?
A light thing would it seem to me to leave all the good things of Spain --
Seeing how precious in mine eyes to behold the dust of the desolate sanctuary.
- by Yehuda Halevi, My Heart Is In the East, 1141, Translated from the Hebrew by Nina Salaman, 1924
Yes, jews were producing good works, and sometimes had positions of authority, but equality was well beyond their reach in Christian or Moorish Spain.
It is certainly true that many Middle Eastern countries are actively hostile both to jews and to the state of Israel, but not every country, or it's citizenry is actively hostile to both. The brush with which you paint is a little too broad.
I received my $99 unit from HP yesterday and love WebOS. I think that the browser could be faster, but beyond that, I'm a fan. It's got me thinking seriously about nabbing a used Pre on E-Bay to complement the 'pad. I was actually saving my pennies to buy the 16GB tablet at $500 when HP announced the $99 deal. I had already decided to buy it, but it was beyond my limit for a casual purchase.
When they announced that they would discontinue the TouchPad, I decided to buy anyway assuming that there would be an android version available for it right away. Now that I've used WebOS, I don't want to give it up. The card interface is brilliant beyond words. Throwing an app to get rid of it is like a science fiction dream.
I design roads for a living (CAD). (Hurray, I got a job after 1.5 years unemployed.) After using WebOS for a day, I can see a touchscreen computer with which I do my designs using a large touch-based screen (angled like a drafting table) and a specialized keyboard (or input area on the 'screen), then revert to keyboard and mouse for text/spreadsheet work. I've used iOS and android on both tablets and phones and not come away with the feeling of much greater possibilities. The latter two seem like limited tools only for consumption, while WebOS begins to feel like something that I can use throughout the day. (It's impossible to ignore that Apple's design heavily informs both WebOS and Android. I also have to recog)
It's too bad that HP doesn't still have engineers at the helm. A company needs MBA's, too, but it seems like any company that innovates and gets in front of the market is led by a designer/engineer. This CAD system I've (very) crudely outlined is as forward-thinking as other tools HP's developed in the past. Unfortunately, they've had MBAs at the helm for so long that I fear they can't see possibilities beyond next quarter's profit. The change is really quite dismaying and rather clearly show's HPs future.
Engineers and accountants tend to be fond of HP calculators. I keep several HP calculators in handy places here and there. I've met a few engineers that used other brands, but every group has its outliers.;-)
I wonder if the folks who manage Area 51, and other secret sites happen to know when these commercial satellites will fly overhead and are capable of taking pictures. Hell's bells, I wouldn't be surprised if they see these images before the companies that own the satellites can see them. You won't ever see anything interesting at Area 51 through google maps, google earth or any other mapping/photo service.
Although it seems remotely possible, I'm also willing to bet that you won't ever see anything interesting (at Area 51) with a balloon that gets in there, either.
This is all speculation, and really just "the world according to me." Feel free to ignore anything I've just said.
Thanks. You just revived a project that I had given up on. I had wrongly assumed that hydrogen was a non-starter due to permeability and didn't bother to check. I'll have to think about how to handle the other danger, though I think my volume is small enough that it's safe.
This goes to show that you should a)check everything and b)recognize that there can be value in "wasting" time.
Improved intelligence may well have made a contribution as well. I also feel firmly that bag screening should remain. Count on passengers' self interest to take care of the cabin, and screen the bags heavily. Make the airlines responsible for damages if one of their planes falls out of the sky and hurts somebody. Bag screening might be better with a couple of dogs added to the mix. I feel that the TSA has managed to prove that it's unnecessary, and from the standpoint of inherent freedoms was a bad idea to start.
Butanol is much less soluble in water, so the bacteria responsible (I'm guessing) probably won't poison itself as yeast does. The solubility of Butanol also goes down sharply as the temperature goes up. Distillation is much less an issue with Butanol than with ethanol.
Butanol also has a higher BTU content than ethanol, so will make a better fuel
It's decomposition that we're talking about here. Presumably, the materials are waste, so the only extra energy is probably small processing costs and transportation.
. ..such follies as butanol from paper scraps or ethanol from corn.
I see what you did there. Would you care to justify the comparison? I think that there are valid reasons to refer to the production of corn ethanol as folly, but I don't see the same case for the other.
. ..but that one is over anyway.
And here, we have the root of the matter. You don't like the lifestyle enjoyed in the US. Fine. Pardon if other people would like to continue the lifestyles that they currently enjoy. The cost of oil, driven up by increasing demand, is doing the job that you seem to want politicians to do. Residents of the US are already driving less without significantly altering their lifestyles. Don't be so bitter about it all, particularly when it's already getting better.
Too expensive, maybe? I bet that there are a bunch of people commenting, including me, who haven't previously bought either one. It was my intent to buy a tablet, at some future date, but when I found that I could get a Webos machine for $99, it seemed like a good time to stop waiting.
Here's an article from 2009 which shows a stark difference between the US and the UK. The article compares the statistics of the USA, UK and several other western European countries about halfway down the page.
Sorry; I wouldn't have said anything if it weren't for "application" instead of "Appalachian." I could have ignored the transposition on it's own, as I've made that same mistake.
We always had the foxfire books around when I was a kid, but I was never interested enough to read them through fully. Now, I'll have to go back and look a little more. (Although I think that I did use one of the books for general directions in building small game snares when I was young.)
I *thought* that was the plane from the movie, but was too lazy to check until you pointed it out. Thanks.
It's not the only application for measuring times in a queue, or other travel-related information. Transportation engineers have started using bluetooth MAC addresses for transit travel times, passenger car travel times, time-in-queue at toll booths, et c. Here's a google search on the subject, if you're curious.

I did. Thanks a bunch for the link. I hadn't heard of popvox.
