On-street Crescent Trail will be worse for bikes and peds

(This is an unedited cross post from Greater Greater Washington)

This post is in response to a Greater Greater Washington post from Dan Reed: On-street Crescent Trail may be better for bikes and peds

I disagree with almost everything Mr. Reed suggests in his post.

For a year or so I commuted through that tunnel almost every day. It is an excellent amenity.

Mr. Reed suggests that the on-street alternative may be safer because of the likelihood of crime, and he points out crime problems at other bike/ped facilities.  This is a red herring argument.  The tunnel has been open since 1998 and crime has not been an issue.  Undoubtedly it will be even less so with greater usage.  The safety benefit of not having to cross Wisconsin Avenue at grade is much greater than any potential danger associated with crime.

New bridge design serves pedestrians and cyclists better

Arlington County has chosen a design (pdf) for its upcoming rehabilitation of the Carlin Springs bridge over George Mason Drive.

View Larger Map

The current bridge has five-foot sidewalks and no accommodation for cyclists.  The new bridge will have 8-foot sidewalks and 5-foot bike lanes on both sides.  The rest of Carlin Springs Drive does not currently have bike lanes, but it is important to plan for the future by including them now. Had the County not included better bike/ped accommodations, then those decisions would have been difficult to change for 30 or more years.

Skeptics are not statisticians: 1% of a data set does not disprove the whole data set.

A friend of mine likes to provoke me by sending links to posts and articles that contradict the established science on climate change. Recently he pointed me to this post that appeared in Watt's Up With That: NCDC data shows that the contiguous USA has not warmed in the past decade, summers are cooler, winters are getting colder.  My friend accompanied this link with this comment:

Well, the figures are in from the NOAA National Climate Data Center and the rest is just high school math. While US CO2 emission has gone up precipitously in the last 100 years the average temperature in the US has gone down. Of course you could look at just the last 15 years and ignore the rest. In this case CO2 has still gone up a lot and temperature was flat. Does this fit with saying the controversy is over and global warming is an established fact.

I countered with some points, but only later realized the biggest flaw with this reasoning, which I'll get to shortly.

Note to Carol Browner: Even if the idea is right, you gotta make sure it's backed by the truth

Carol Browner was quoted in the Washington Post on Sunday.  The quote was from an energy conference held in Washington a week earlier.  Here's the quote in its entirety:

People like to pooh-pooh regulations and suggest that, somehow or another, regulations are not good for business. But, in fact, regulations can create business certainty and business opportunity. When the government puts in place a requirement and standard, that means there’s the certainty of a return on capital investments.

And we have a long history in this country of doing just that. If you go back to 1990 when the Congress decided to ban chlorofluorocarbons, CFCs, a market opportunity was created. And we found a solution or a replacement for CFCs, which were dangerous to the upper ozone, and we did it more cheaply and more quickly than anyone anticipated.

Some in this industry and the natural gas exploration extraction industry have not been as forthcoming as others. . . . I would just encourage the industry to be as transparent as possible in an effort to ensure that this is a thoughtful discussion about how we move forward.

"Natural" equals Magic

Follow the comment thread after virtually any on-line article on climate change, and you will find deniers/skeptics who will claim that the warming we are experiencing is just "natural forces," not caused by humans.  They will often make a statement like, "since it is UNPROVEN that CO2 is a contributor to climate change." or " I believed global warming was occurring not because of mankind's actions but because of the natural rhythms of the planet and our sun."

A friend of mine, in fact, has invoked this same idea to me: that climate change is some sort of natural artifact.  This is the equivalent of saying that what is happening is caused by magic.

Farragut "Virtual" Tunnel (Farragut Crossing) Now Operational

I don't know if I should claim any credit for this finally happening, but I have been fairly vocal about it for a long time on several forums.  Finally on Saturday, October 29, 2011, the "Farragut Crossing" virtual/invisible tunnel transfer option began between Farragut North and Farragut West stations.

Here's the first line from my original post below:

"I can't take credit for this idea--I read it somewhere else--but it's so good that it needs to be promoted and publicized until Metro takes notice and implements it."

That was August 30, 2008, 38 months ago.  I'm glad to see it finally happened, but it's a bit discouraging to see that a no-brainer idea like this one can take so long.  Imagine how long something expensive or contentious would take.

For history buffs, here's a comprehensive listing of all my posts and some other relevant links.

Kids keep getting smarter. More and more bicycling to school.

Twice in the past (here and here) I reported on the bikes that were parked in the racks at Swanson Middle School in Arlington.  Two years ago there were thirteen.  Last year there were eighteen, and they had expanded the racks.  This year on bike-to-school day there were twenty-one, and as you can see in the photos below, they are just about out of room in the bike racks again.  One rider's bike is parked on a nearby tree.
It's great to see more and more school kids riding bikes to school (and some staff, too).  There are about 800 students and staff at Swanson, so these bikes represent 2-3% of the total population.

State of Folly 5 - How Crichton is wrong about glaciers

This is the fifth in a series of posts related to Michael Crichton's State of Fear, which I just read this summer. [previous posts here and here and here and here]

From page 530, a conversation between Kenner and Ted Bradley:

"How many glaciers are there in the world, Ted?"

"I don't know."               "Guess."

"Maybe, uh, two hundred."

Who owns the signs? And why won't they take them down?

I've noted a couple of signs in Northern Virginia that indicate the way to Dulles Airport.  One is on Route 50 in Arlington just past the Courthouse exit at the 10th St. exit.  The other is on Little River Turnpike between Braddock Road and Old Columbia Pike.

View Dulles Airport signs in a larger map

Here's what they look like:  

This is the sign on Route 50 in Arlington.

Here's its location.  You can see the 10th St. exit sign that is in the median.

Here's the one on Little River Turnpike.

The existence of these signs raises a number of questions:

• Who owns them?
• How long have they been there?
• Why are they still there?
• What purpose do they serve?

I suspect these signs date from before I-66 was built, since no one would take Route 50 to get to Dulles with I-66 available.  Also, neither of these--as far as I have noticed--has any follow on signs, so a traveler who noted the sign would never see another one to guide them on their way.  A single directional sign far from its destination without any more to assist the traveler is probably worse than no sign at all.

There may be more of these Dulles airport signs.  Have you seen any?  Where?

Taking a macro view, who is responsible for signage in general?  Once a sign is placed is it ever taken down?  I've seen signs in my neighborhood that have rusted so badly they can barely be read and that are completely outdated.  Signs like these are everywhere, and they just accumulate.

Perhaps every sign should have information on the back of it that tells who owns the sign and who is responsible for it, as well as contact information.  At least that way someone could try to follow up and notify the owner if it gets damaged or becomes obsolete.

State of Folly 4 - How Michael Crichton was wrong: 1970s Global Cooling

This is the fourth in a series of posts related to Michael Crichton's State of Fear, which I just read this summer. [previous posts here and here and here]

On page 394, the "arch-villain" Henley (in the plot, he is the key character behind the efforts to manufacture big climate events) says:

Solving the Lynn Street/Lee Highway Bike/Car Conflict

The intersection of Lee Highway and Lynn Street in Rosslyn, where the Custis Trail crosses Lynn St., has been the subject of great scrutiny lately. (GGW reported on a recent meeting at this very intersection.)  This is one of the most dangerous intersections for cyclists in the Greater Washington area. By reconfiguring the exit ramp for the Key Bridge, this conflict can be entirely removed, dramatically improving safety while also potentially improving traffic flow.  (This post has been cross-posted at Greater Greater Washington, including a number of reader comments.)

The problem at this intersection is traffic turning right from the I-66 off-ramp onto Lynn Street traveling towards the Key Bridge.  This traffic has a green light at the same time as the pedestrians and cyclists have the cross signal. There are two lanes of right turning cars (and sometimes cars in the third lane turn right illegally). By shifting the Key Bridge traffic to the north of the Custis Trail crossing, this conflict will be eliminated.

It's already here. Not far in the future. Climate affecting politics and disaster relief, that is.

The most recent political skirmish in DC was over $1.6 billion in disaster relief funding. The GOP was working to turn this into a political negotiating tool to extract other concessions. It didn't end up making much difference, and the political blogosphere saw it as more examples of dysfunctional government.

I, however, see it as not only that, but also a canary-in-the-coal-mine moment. As the future of climate change bears down on us faster than anyone was expecting, disasters like this year's (9 $1-billion+ disasters already this year) are going to require more and more emergency funding. Eventually these disasters are going to require much bigger political decisions than what we see now. Remember, Nicolas Stern predicted that climate change could take up to 20% off global GDP. That's not only a huge hit on available resources, but there will also be enormous costs to actually deal with the floods, droughts, storm surges and other direct effects of warming-enhanced events.

Science textbook gets science right!!!

Last summer my son was required to read "State of Fear" by Michael Crichton in preparation for his Geosciences class that all high school seniors are required to take at his school (it's a school that specializes in science and technology).  That made me nervous, knowing that "State of Fear" has been widely debunked as a source of useful information on climate science (see my series on State of Fear here).  I was hoping that his teachers were not going to use it as some sort of instructional material on climate change.

I was immensely relieved, though, when I read the very first sentence in his textbook:

State of Folly 3 - How Michael Crichton was wrong: Humans insignificant?

This is the third in a series of posts related to Michael Crichton's State of Fear, which I just read this summer. [previous posts here and here]

On p. 709, one of Crichton's key characters, John Kenner, who he presents as the level-headed, intelligent understander of all things climate, says, after describing the ordinary violence of the earth's weather:

The nasty little apes that call themselves human beings can do nothing except run and hide.  For these same apes to imagine they can stabilize this atmosphere is arrogant beyond belief.  They can't control the climate.

Yet we know that to be undeniably false.  We are, in fact, already controlling the climate.  We've raised it a degree or so Celsius in the last 100 years.  "Unequivocally" according to the best climate science on the planet.  We may not be "controlling" it very well--more like sending it out of control.  The point he was trying to make is that humans are just too small to make any difference to the enormity of the earth's systems.  Wrong.
