Breakfast links: There's still hope
Can bike lanes keep proliferating?: With the the easiest bike lanes are already done, future lanes will require some tradeoffs. DDOT's decade-long methodical expansion of DC's bike infrastructure has made a believer out of Harry Jaffe and many others, hopefully increasing support for some reallocation of road space. (Housing Complex, Examiner)
Alexandria still pondering CaBi: Alexandria's Transportation Director is proposing to pilot Capital Bikeshare in Old Town and Carlyle, but one critic wonders if the city's underfunded transit system could better use the money. (Gazette Packet)
DoD could hold BRAC moves: The defense bill currently before the house would allow DoD to delay several BRAC moves up to a year. Jim Moran and Bob McDonnell have already written Secretary Gates asking to postpone the Mark Center opening. (Post)
Issa would help DC: Vince Gray and Kwame Brown went up the hill expecting to be beaten up by Republicans; instead, Darrell Issa (R-CA) promised to push legislation keeping DC from getting stuck in future federal shutdowns. He also offered to stop having Congress meddle in DC's affairs. No, just kidding on that last part. (Loose Lips)
Hand wringing over gas prices: In 2008 the DC council lifted a ban on gas resellers also owning gas stations believing it would lower gas prices. Now they want to restore it, believing it will lower gas prices. (Post) ... How much transit could we pay for with all the money and time spent investigating gas companies? (Examiner, LA Times)
Marylands tolls cheap, need raising: Maryland's proposed commuter toll hike may be steep, but will only bring tolls to where they should have been several years ago. The ICC debt will necessitate even higher tolls sooner rather than later. (Baltimore Sun)
Blumenauer wants better commuter benefit: Congressman Blumenauer (D-OR) wants to create permanent mode parity across the commuter benefit to promote non-SOV commuting, including doubling the bike benefit to $40/month and allowing cyclists to take transit benefits in addition to the bike benefit. (BikePortland, Grist, Gavin)
Big racial gap in housing, here & elsewhere: There's a big gap between blacks and whites in DC concerning how many can afford to buy homes. The good news, such as it is, is that it's just as bad in other cities and worse in New York. (Housing Complex)
And...: Just because you install streetcars doesn't mean you can't swap in buses on the rare occasion when you need their flexibility. (Eschaton) ... More pedestrians were struck by drivers in this particularly tragic week. (WUSA) ... With BIXI-based bikeshare systems proliferating, can a company design bags and panniers for their racks? (WashCycle)

I would like to see the state constitution amended to prohibit the State Legislature and Governor from raiding the various dedicated accounts to pay for things that those accounts were not setup for.

Tolls should be collected either electronically--reducing overhead--or should be so steep as to keep drivers off the roads (reducing repair costs of roads)

Agreed, but depends on what you define as other things. I am ok with 95 tolls for example being used to also help pay for the ICC or other MD roads. They should not be used for the general fund.
Raising tolls should not be done to keep cars off the road. People do have ligitimate reasons to drive.

The food you eat passes through those toll facilities to get to your dinner table.
Are you willing to pay more for your food just to satisfy your desire to punish the users of those toll facilities?
FYI: 18 wheelers pay more then 3X the fare then do cash fares paid by driver of passenger cars and light trucks.

Regarding bikeshare in Alexandria, the critic in question just doesn't see how bikeshare will financially work in the city. I should also mention that this person has been vocal about preferring buses over streetcars at the city's high capacity transit meetings.

That is what I meant, MTA revenue stays within the MTA. Tolls collected regardless of where they are collect would be used to retire the MTA debt regardless of where it was spent.

I have to think the cost will be so small to be irrelevant. Also consider that if they find malfeasance, the companies can be fined and it will be a net benefit (though there is no guarantee that that money would go to transit).
@Sand Box John:
The tolls for an 18 wheeler have practically no effect on the price of food, even if it is three times what cars pay. Things like fuel and labor are much bigger components. And if it does have some market affect, won't it encourage alternative transport modes (like freight rail)?

They also have 4x the number of wheels, and weigh up to 20x as much.
The problem with raising tolls is that the costs will be borne by independent truckers.
by andrew on May 13, 2011 10:28 am • link • report
Good point, but there is no reason why hikes could not be phased it. Go up for cars first perhaps. What about charging for more for peak fares? Perhaps to encourage people to take trips at different times.
by Matt R on May 13, 2011 10:41 am • link • report
That 3X figure I quoted is on the conservative side of what the fare really is. Last time I passed through a cash lane at the Bay Bridge the fare for a 5 axle vehicle (18 wheelers) was $15.00, that is 6X what is paid by driver of passenger cars and light trucks.
18 wheelers do not inflict 6X the damage to roads compared to passenger cars and light trucks.
Based on my observation some of the damage to roads can be attributed to poor quality of maintenance, poor quality of material used and improper design for the environment and volume traffic carried on the road.
by Sand Box John on May 13, 2011 10:42 am • link • report
18 wheelers DO inflict much more than 6x the damage to roads compared to passenger cars and light trucks. The damage increases with the fourth power of the weight of the vehicle, according to estimates in this article in the Journal of Forest engineering: http://www.lib.unb.ca/Texts/JFE/bin/get6.cgi?directory=July99/&filename=martin.html.
This Texas state analysis reaches similar conclusions, and says that an 18-wheeler at the 80,000-pound weight limit inflicts as much damage on the road as 9,600 cars (or six trucks hauling 50,000 pounds each). http://www.window.state.tx.us/tpr/btm/btmtr/tr05.html
And then there are the higher costs of building roads and bridges to accommodate heavier trucks in the first place, and the disproportionate effect trucks have on congestion (they can massively magnify and perpetuate volume-based congestion, due to their slow acceleration).
by Jeff on May 13, 2011 11:48 am • link • report
The statement that '18 wheelers do not inflict 6X the damage to roads compared to passenger cars...' is only correct in that a factor of 6 is a gross understatement.
Research conducted by AASHTO in the 1950s and 1960s established that damage to the road increases as the fourth power of axle weight. This means that if you double the weight, you get 16 times the damage; if you have 10 times the weight you get 10000 (ten thousand) times the damage. Now things get a little tricky with tandem axles and double tire axles, so a concept called ESAL=Equivalent Single Axle Load was developed. It is a (linear) measure of damage done to roads by different vehicles.
Your prototypical 18-wheeler, a five-axle tractor with a single trailer, has an ESAL of about 1.2. A car would have an ESAL of about 0.0004.
So the truck does about 3000 times more damage than the car. Should the toll be 3000 times as large as well?

Using just a bit of paint, DDOT recently transformed 11th Street SE from Pennylvania Avenue to the 11th Street Bridge from a speedway with four lanes for cars to a neighborhood street with two bike lanes, two car lanes and a wide median. I love it -- despite the whiny letter the Committee of 100 sent to Mayor Gray last fall, the war on cars continues!! I guess the "real stakeholders" just don't have the influence they used to..........

Shhhh.
Are you *trying* to provoke a backlash!?!
by oboe on May 13, 2011 2:14 pm • link • report
I bike, run, and drive on 11th St SE. Vehicle speeds have not been affected at all. If anything, the fact that left-turning traffic now has its own lane has made traffic on that road flow more smoothly, even with the speed limit taken down from 35mph to 25.
It's also changed the street from a "no-go" area for cyclists to a primary backbone of my daily commuting route.
