MIT Students Hack Boston Charlie Cards

The Facebook generation makes hacking transit look easy. From the Subway Blogger:

Apparently, some students at MIT made it a class project to hack the Boston subway system (aka the T). As a matter of fact, the title of the project is: “The Anatomy of a Subway Hack: Breaking Crypto RFIDs & Magstripes of Ticketing Systems.”

Now, the students are computer security majors, so you can see the fit. They planned to give their 80+ slide presentation at Defcon, a very large security conference. However, the MTBA sued to have the presentation stopped. A judge ordered a temporary restraining order keeping the presentation quiet.

It's my understanding that Defcon doesn't have a lot of leaks. I'm not really sure what Boston is worried about. If these kids can do it, certainly anyone can if they have the appropriate skills.

The Real Freedom Machines

I really shouldn't have to go through all the reasons why this article is just wrong. It's the same junk we've heard over and over again. But what it shows, is what the other side is really thinking. A lot of folks try to argue intelligently, but here is usually what city and transit planners are up against.

1. Transit Doesn't Pay for Itself - We've covered this before. Roads don't either, get over it.

2. Transit and Bikes are Stealing from Cars! - Mary Peters started this junk science and apparently people are repeating it. Then there is the user pays junk that TxDOT debunked recently. Didn't they get the memo?

Roads have gone unbuilt because the "user pays" principle of transportation has been violated. Highway trust funds (your highway user taxes) have been siphoned off. Whereas other forms of transportation receive subsidies, drivers pay subsidies.

Supposedly our fuel taxes go to build and maintain roads and bridges. But for many years at least a fifth of the money has been diverted into high-priced mass transit projects, bicycle paths and tourist attractions instead. That's a huge factor in the backlog of unbuilt and unkempt roads and highways.

3. Cars are More Energy Efficient - People are starting to get all righteous with the Department of Energy Databook which shows transit is much more efficient than a single driver car. Yet the databook assumes cars all carry 1.5 people per car and thus adjusts its numbers accordingly. Are you !$&#%^ kidding me? Istook takes this as gospel and doesn't mention anything about those pesky things like people that take transit also walk and bike more, and drive less over all. You know, this kind of thing. From the 1994 Portland Travel Survey...


So even if we did travel 1.5 people to a car, they still drive twice as far negating any energy efficiency. That 1.5 number is still ludicrous. Even more ludicrous, these comments.

Nor does transit save energy. U.S. Department of Transportation figures show that transit buses actually consume more energy (in BTUs) per passenger mile than autos do! Further, as charted by the U.S. Department of Energy, American buses average 4,650 BTUs per passenger mile, compared to only 3,702 for autos. Rail travel does slightly better, with 3,172 on average, but rail's energy consumption figures are higher in cities due to stop-and-go nature of commuter rail.

Again, that assumes 1.5 people per car. And rail always operates in cities, so I'm not sure what he is getting at here except to say, here's what the numbers say, here's what my brain thinks. One would argue that cars energy consumption is worse in cities because of stop and go as well. I'm really confused with this idiocy.

4. This is Just a Trick to Save the Planet. Hahaha. Those tricky planet savers.

But not everyone is thrilled with the prospect of having to sacrifice our freedom of mobility because "green" politicians chose to "save the planet" by hampering our country's ability to produce affordable energy.

Is it really a choice? And why does freedom of mobility mean all car all the time. I feel like I can move quite freely here without driving the car, I at least have the choice to do so. But the real meaning of this is "Why won't they let us drill until the carbon chokes us?"

3. Libruls are Forcing Me Into Transit. Here's the funniest comment of the day, comparing transit advocates to the Tokyo Train pushers.

Trying to force everyone onto mass transit will never work. But be prepared for those who will use today's challenges to push us in that direction – perhaps as brutally as the professional pushers who cram riders into the cars of the Tokyo subway system.

It's time for drivers to stand up against efforts to demonize the automobile. Forcing people to use a particular mode of travel is not the American way. Life is better when you have the freedom to drive, not just find a ride or wait at bus stops.

I don't remember the last time I tried to force my friends and relatives to ride mass transit over taking the car. In fact, I own a car and there are many times when it is useful to have. No one is forcing them to take transit, I just want options. I want to have the choice. And I know that is the wrong frame, the choice frame. But what else is there? How can we talk about these things using the right frame. If I were a Karl Rove disciple, I would just say driving cars funds terrorism. That would be the end of it right? Anyone got a good frame?

The Benefits of Electric Transit

After a few posts where people have been wondering about the benefits of electrification, I thought it might be useful to post on here the reasons why electrification is not just an energy argument, but rather an efficiency and operations benefit.

1. Point Source Pollution

It has been revealed in the last few years that higher rates of respiratory ailments including asthma occur near freeways, especially places like the Port of Oakland where diesel trucks and ships move in and out near the West Oakland neighborhood. In terms of transit, these emissions occur along a complete corridor. With electric propulsion, it occurs at one source, the power plant. This point source pollution is the issue and in the next 30 years of any project, we have to assume that alternative energy sources will come on line (if they haven't already, San Francisco for example gets electricity from hydro, Calgary is 100% wind) or better scrubbing technology will be available on coal and natural gas plants.

2. Operations Efficiency/Accelerations

Electric drive transit also has faster acceleration and stopping. According to TCRP report 59, 50% of energy for buses specifically is used for acceleration. Hybrid electric buses are able to capture 25% total through regenerative breaking. This type of system is available for rail systems as well, recently being introduced in Sacramento.

Electric motors also create more torque for faster acceleration. For example, the DART Kinky Sharyo LRV accelerates at 3 miles per hour per second(mphps). The Colorado railcar DMU accelerates at 1.44 mphps (1.6 according to Caltrain specs). Buses typically get around 1.5 mphps.

Caltrain has put together a matrix of all the specs for cars they are looking at for the future. DMU is 1.6 mphps, EMU is 2.0-2.5 mphps, the savings by using EMUs over a 15 stop run estimated for Caltrain is 10 minutes every run. That is a big time difference that would allow for more runs every hour. If the run takes about an hour. That means they can have 1o minute headways with 6 vehicles. You would have to add another vehicle with another driver to get the same with diesel.

If you've ever been on a PCC, they have high torque and accelerated at one time at 4 mphps often tossing patrons to the ground. It was later revised to 3.5 mphps. This is at the expense of top speed, but since they stop more often its not as necessary.

Another benefit is the lighter cars used because of electric motors being lighter which reduces wear and tear on the track as well. The electric motors also have less moving parts meaning they last much longer. The official amortization period for rail vehicles is 24 while buses are 12. However there are still PCC cars still in operation and some rapid transit vehicles like BART are reaching their 40 year mark (they should really be replaced soon though).

3. Energy Conservation

Another issue is energy conservation. In addition to regenerative breaking, there is the power draw during stops and at the end of runs. Commenter NJH mentions that when passing Diridon Station, trains are always idling, wasting energy. Electric vehicles do not need to do this, especially at stops.

Electrification is not that expensive either. Even with copper costing more and more, NJH makes the calculation.

Regarding the price of copper, you have: 3.4$/lb*pi*(0.5cm)^2*mile*9g/((cm)^3)

Definition: 8526.9645 US$

So we're looking at $8.5k/mile for the conductor. Double it, add in connections and throw a bit out for waste. The copper is not going to be a big part of the cost (given that estimates are usually around $1M/mile).

I've heard about $1.5 million per mile is somewhat normal, which is small change when you think about the benefits as mentioned above.

The Option of Urbanism: Subsidizing the Rich

Here is another view of it from the Option of Urbanism. We've been taking quotes for the last week from the book.

According to Myron Orfield's Metropolitics, the affluent outer-ring suburbs in the favored quarter "dominate regional economic growth and garner a disproportionate share of the region's new roads and other development infrastructure." Orfield also pointed out that much of the funding for this infrastructure is raised from the region as a whole. For example, all car-driving residents in the region pay gas taxes to partially support the building of highways, and taxpayers of the region as a whole pay the rest of the money through their income, property, and sales taxes.

So this happens for roads, but people yell and scream bloody murder when they are taxed for transit and "it doesn't help me directly". The worst part about this as well is that cities are slowly signing on to their own declines.

The unlikely consequence of this pattern of infrastructure development is that the whole region pays for infrastructure that tends to be placed in the favored quarter; the poor pay for the infrastructure of the rich. According to Orfield, the central cities of Minneapolis and St. Paul, for example, pay $6 million a year to help move their middle class households and businesses to the edge of the region.

Part of the problem is the regional competition for jobs. Minneapolis has a tax base sharing program that might alleviate this a little, but most regions are not so lucky. And there is still exporting going on to places like Bloomington and Eden Prairie.

M1ek has discussed this before and James Rowen covered a similar issue for Milwaukee in talking about how much they give to the regional planning commission, and how little they get out of it. Perhaps this is something that needs to be put in mayor's and city council members faces. DC, for all its flaws has the right idea of trying to take care of its citizens instead of the folks who take advantage of their services during the day, but drive back out at night.

It's That Time: Olympics!

Oh man I've been waiting for a while for this. Friends of mine are competing so I'm going to be reporting on what they are doing. I should also note that the head track coach at the Olympics, Bubba Thornton, was one of my coaches in college. It was cool to see him on TV.

Exciting news tonight is that Lopez Lamong got to carry the American Flag. He, as I was, is a 1500 meter runner. I've met him before and he's a great guy. As one of the Lost Boys of Sudan, he was able to escape that country and come to America for a better life. Here's a video of Lopez talking about hardship. He does have a bit of a reputation for elbows, but we won't hold that against him.

Caltrain Must Hike Fares Too

Caltrain is going to raise fares in order to cover diesel fuel cost spikes. Imagine if it were already electrified. Less cost and cleaner air. Why do cities still think DMU's are a good idea?

Kansas City Will Vote on Light Rail

Looks like we have another ballot measure to watch on Election Night. If you're just catching up on this whole KC light rail rollercoaster, here's a cheat sheet.

BRT Will Kill Your Children and Drink Their Blood

Ok. I'm not a huge fan of BRT as you know, but this is ridiculous. Some people are just over the top. Yes I know it's the Berkeley Daily Wacko, but the fact that there are people out there like this shouldn't come as a shock.

BRT is bigger than you think. Its pattern follows the national trend that General Dwight D. Eisenhower, Supreme Commander of the Allied Forces in Europe in World War II, famously named the military/industrial complex. Eisenhower (a Republican dedicated to preserving the Constitution) said government and private industries are determined to feed the war machine at the expense of all else and would ruin this country and the world if not checked by an alert citizenry.
...

“Policy-makers” care nothing for the residents and businesses along Telegraph Avenue. Not only does BRT mean turning Telegraph into an un-bike-able traffic nightmare; it also means large scale re-development under the rubric of turning Telegraph into a ‘transit corridor’: goodies for developers, fees for the city, and “closed” signs for existing businesses, many of which are likely to be replaced by corporate chains that duct money out and away from the local economy.

Because there's nothing like improving transit and slowing down cars for killing a streetscape!
