Sustainable Trail Design

No matter where I travel, I always see some unique “bike thing” that maybe I can bring home to B’more.  Out of town this weekend, I got to do some mountain biking on some very technical & well designed trails.   While these two trail systems were in very different terrain, they both exhibited fun challenges with resistance to rain & wear.

There’s a common misconception that mountain bikers just want to shred and ignore environmental impact; but in reality it is the mountain bike community who have promoted trails that last when designed properly.  IMBA (International Mountain Bicycling Association) encourages environmental standards through their Sustainable Trail Design Guidelines and through local affiliates that do much of the trail maintenance.

My first ride started with a road climb up to the ridge of The Western Slope of Massanutten where rocky trails drop over a 1000′ to the adjacent valley.  The Shenandoah Valley Bicycling Coalition works with public & private land owners to construct and maintain an intricate network of trails here.  Local rocks were used to construct tabletops, rolling grade dips, trail armoring, and stream crossings which divert rainwater and provide riders with opportunities to catch some air.  On my climb up the Pink Trail, I passed Tim, a local maintainer, who indicated this trail was only a year old and was so well designed that it didn’t need any maintenance.  That’s quite a challenge considering the amount of bike traffic I saw.  Not to mention, the black bear traffic I saw using the trails.

Heading back towards Baltimore, I stopped at Wakefield Park in Fairfax County, VA.  Utilizing the rolling terrain and power line easement, MORE (Mid-Atlantic Off Road Enthusiasts) worked with the county and utility companies to design world class trails as several mountain bike races are held here annually.  (MORE also maintains many local trails like Loch Raven and Patapsco.) After the long climbs of Massanutten, Wakefield was no problem and down-right fun.  Here I enjoyed a series of insloped turns, boardwalks and jumps.

If you would like to join a group ride or help maintain area trails, visit MORE’s website and check the calendar.

$7-a-gallon gas?

By BEN LIEBERMAN
President Obama has a solution to the Gulf oil spill: $7-a-gallon gas.
That’s a Harvard University study’s estimate of the per-gallon price of the president’s global-warming agenda. And Obama made clear this week that this agenda is a part of his plan for addressing the Gulf mess.
So what does global-warming legislation have to do with the oil spill?
Good question, because such measures wouldn’t do a thing to clean up the oil or fix the problems that led to the leak.
The answer can be found in Obama Chief of Staff Rahm Emanuel’s now-famous words, "You never want a serious crisis to go to waste — and what I mean by that is it’s an opportunity to do things that you think you could not do before."

Cars Cause Congestion

Komanoff found that every car entering the CBD causes an average of 3.23 person-hours of delays. Multiply that by $39.53—a weighted average of vehicles’ time value within and outside the CBD—and it turns out that the average weekday vehicle journey costs other New Yorkers $128 in lost time.
He translates all traffic impacts—delays, collisions, injuries, air pollution—into dollars and cents; that way, it’s easy for users to compare the benefits and costs of different plans. He has even come up with a plan of his own that would, according to his calculations, collect $1.3 billion in motorist tolls per year—all of which would be spent on improving public transit—and save $2.5 billion in time costs by reducing delays. To that, add $190 million from decreased mortality as a result of making streets more bicycle- and pedestrian-friendly, $83 million in collision damage reduction, and $34 million in lower CO2 emissions.
he produced a detailed statistical analysis of pedestrian and cyclist deaths—it showed that casualties are not random, unpredictable accidents but the foreseeable result of given traffic conditions.

To Address Demand for Oil, We Must Focus on Transportation

by Earl Blumenauer

The truth is that we are drilling 150 miles offshore and one mile below the earth’s surface because we have run out of accessible oil. Most shocking is how small a difference this oil makes to our energy needs. The 35-60,000 barrels spewing daily from the Gulf floor would be enough to power our nation’s cars for just four minutes.

They Have to Do the Right Thing or Else They’re Going to Get Killed

Last year, we posted a piece about a couple of shock jocks in Detroit who thought it was funny to talk about throwing things at bicyclists.

This year, the hateful talk is coming over the airwaves from Pittsburgh.

Streetsblog Network member blog Reimagine an Urban Paradise has been following the story of a Pittsburgh DJ, Mike Pintek of KDKA, who made some ugly remarks about being “tempted” to hit people on bikes with his car. The audio has been taken down, but here’s a partial transcript of what Pintek said from Reimagine’s author, Lolly:

“There are some bicyclists who are just these arrogant little dorks that think they can do anything they want because they’re on a bicycle and ‘we’re being green and environmentally friendly’…

“I have been thoroughly tempted — I haven’t done it ’cause I’m not going to do it — I’m not that kind of person…but I have been so tempted to just bump ‘em.

“I have been so tempted to pull up behind them when they’re doing this — you know spread out across the road — put my car in neutral, jam the accelerator down, race the engine and scare the living crap out of them.

“They’ve got to stop being so arrogant about what they’re doing. They’ve got to obey the rules. They have to do the right thing or else they’re going to get killed.”

This all is playing out in a city where several bicyclists have been attacked in recent weeks by gangs of kids, as reported by Bike PGH.

Reimagine’s Lolly has this to say about what she thinks the consequences should be for the DJ:

Driver’s licenses are a privilege, not a right and if a person announces their desire to use their vehicle as a weapon, they should lose their license. If they use their job to incite others to commit violence, they should lose that job.

She also notes that in the case of a San Francisco driver who allegedly did target people on bikes and used his vehicle as a weapon, the charges are felony attempted murder.

PGH Is a City and WWVB have more. Apparently Pintek is going to talk about what he said on his show today. We’ll keep an eye on it.

On another note entirely, we’d like to thank the folks at the Top Online Engineering Degree blog for including Streetsblog.net on their list of Top 50 Blogs for Civil Engineers to Read. It’s a terrific list that we’re looking forward to digging into. You should definitely check it out. And we’re honored to be included.

Whodunnit… Henry Ford.

“My experience convinces me that the criminals of twenty and thirty years ago were cleverer, more daring and enterprising than the criminals of today…. The increase in serious crime is due not to education, but to the incoming of the motor-age. The introduction of the motor-car has made life easy and less risky for criminals. They travel faster and farther afield, and this increased mobility makes the chance of capture infinitely less than it used to be. The activities of criminals knows no bounds… In the old days a smash and grad was done by a pedestrian with a brick, and he had to rely on his legs to get him quickly out of danger of capture. The motor-car gave him considerably increased facilities both for committing a crime and escaping detection.”

BETHESDA, Md. (WUSA) — A spokesperson for the Maryland National Capital Park Police said two bicyclists were injured after a head-on collision on the Capital Crescent Trail near Little Falls Parkway.
Sgt. Lauryn McNeill said it happened Friday around 8:30 a.m. She said a cyclist headed for the National Institutes of Health moved around two pedestrians and into the path of an oncoming cyclist.
McNeill said both cyclists were transported to Suburban Hospital for treatment.
