"Some Perspective On The Japan Earthquake"

A lot of people have written about how the Japanese earthquake is a perfect example of high engineering standards and rigorous training and preparations paying off, but I especially liked this account.
A train pulling out of the station had hit the emergency breaks and was stopped within 20 feet — again, just someone doing what he was trained for. A few seconds after the train stopped, after reporting his status, he would have gotten on the loudspeakers and apologized for inconvenience caused by the earthquake. (Seriously, it’s in the manual.)

"Durable" instead of "Sustainable"?

A little thought by Human Transit. I'm not sold, though the throwaway comment about "Resilient" caught me eye. [several weeks old, but then I have things I've been meaning to read for far longer and I'll probably post some of those, so, tough]

2010-11-03 Northampton Meadows LandArch Project

We did a one week overview study of the Ward 3 neighborhood of Northampton, MA as part of an ongoing open spaces assessment and revitalization proposal with the community. These are some photos from my site tour of "The Meadows" that came out nicer than just a simple reference snap. (And show off the quality of the iPhone 4's camera!)

This is the only one I did any post processing besides simple cropping - I tweaked the colors slightly.

2010-11-04 Landscape Architecture and City Planning Project Snapshot
I decided to procrastinate during this INTENSE project to snap a random process shot. This is when I'm trying to organize my thoughts into some vaguely-cohesive presentation of my findings. (Just barely out of frame is the DISASTER zone I call our living room.)

the conflict between high speed passenger service and freight rail in america

(a minimally-edited off-the-cuff draft):
As the Wall Street Journal summarizes in an article I find a bit skewed and thin on context, the freight railroads see national high speed passenger service as a serious threat [via The Infrastructurist]. And, while we desperately need passenger service of anything even pretending-to-resemble a functional national network, the freight railroads are right. Passenger service is a huge liability for them. After decades of starvation, the US (well, US and Canada - the two are functionally one and the same in the railroad world) railroads have finally had significant growth for the past couple decades, and in the past decade have actually reached the point of spending billions on infrastructure capacity upgrades to handle the traffic. They now carry way more traffic than ever on a fraction the route-miles through much more efficient networks. North America (US and Canada primarily, but Mexico is catching up fast) has the most successful and efficient freight rail systems in the world, and one of the few that is fully-privitized. They simply do not have the capacity for passenger service on any of their core lines without heavy capacity expansions. When there is plenty of open capacity on a line, the incremental costs of an added train are not too major - when the line is at capacity, incremental costs can escalate exponentially in extreme cases (need another track and you're in a mountain range? have fun blasting lots of rock...). A single passenger train actually has the capacity needs of several freight trains - the greater the speed-disparity, the more a passenger train delays the surrounding freights, and their tighter scheduling requirements (federally-regulated and hard-fought in the courts over the decades of Amtrak's life) mean that a delayed passenger train destroys the schedules of every other train around it. Excellent freight and passenger networks can coexist, but that takes massive capital, and exists almost nowhere in the world. Not in Europe, thats for sure - all those countries in western Europe with their excellent passenger service? Yea, they have freight networks varying from small-and-plucky to abysmal. If you have to choose one or the other, then America needs freight way more given our geography, economy, and the far greater efficiencies of freight transport than passenger by rail due to the inherent nature of their traffic patterns (with occasional exceptions like urban mass-transit).

In all of this it's also important to remember that our freight railroads have grown incredibly-protective and wary of any government involvement - one of the biggest things that saved the entire industry from death was the Staggers Act which largely deregulated them and eliminated decades (close to a century even?) of heavy pricing regulations - a holdover from the Robber Baron era. They are still massive corporate interests with great power, but despite being many times larger geographically than ever before (to oversimplify: UP and BNSF are Mississippi to Pacific, CSX and NS are Mississippi to Atlantic, CN and CP are Canada), they have a tiny fraction the actual power and have to compete with the massively-Federally-subsidized highway network. Amtrak was a government bailout that took the passenger service out of the hand of the freight railroads and relieved them of a government-mandated service were collectively hemorrhaging some $700 million annually as early as the '50's and literally bankrupted several mid-sized railroads. But it was inherently a compromise that satisfied no one. It retained a fraction of the routes and was structured in a way that it would be perpetually fucked financially and politically, but they survived at all. And it still forced the freight railroads to give these trains priority dispatching that earned them no money, but at least they were not directly costing them millions.

If we want any remotely-decent national passenger network, we need to mimic the approach of the regional commuter agencies negotiations with the freight railroads. If guaranteed their train capacity needs, some liability protections (liability costs are OBSCENE these days), and some say, they will happily cooperate, hand over some control, and even pitch in some on infrastructure upgrades as long as they see some benefits. The key is not expecting them to give up capacity, control and liability just because.

(Interestingly I am biased in both directions on this matter - as a US railfan, the freight networks are something I know well and care about a lot, but similarly as a train nerd and someone interested in transportation planning, I have always thought our passenger network needed tens of billions in investment annually for a couple decades at least to fix the crimes of the past half-century.)

Rail vs Bus transit planning, infrastructure design & emotional fads

humantransit.org - The beginning of this article isn't particularly new in any way, but a decent refresh of the contrasts in abilities of bus vs rail technologies for urban transit. The much more interesting part is towards the end - Jarrett talks about the historic legacy of infrastructure geometries that were influenced by the emotional climates of their time - this seems to be a defining feature of many (all?) major infrastructure trends throughout generations. The (difficult) key is differentiating emotional fads from important paradigm shifts when making these sorts of planing decisions.
Look around your city and I bet you can find some long-term infrastructure that's not at all what you would build today, and that presents obvious practical problems for the life of the city now. Those facilities were designed to meet the emotional needs of a past generation, and some of these were built in spite of obvious mathematical or geometric absurdity because of the passion of the moment.
...
Things were built a certain way to meet the emotional needs of a moment in history. Today, the emotions have changed, but the geometry hasn't. So we're still stuck with the geometric consequences of those emotional decisions.

(also? whoadamn that's an amazing comment thread he's got going there...)

Aukland Transit Privitization Case Study

a cautionary tail of the dangers of transit privatization (I know of no place where fully-privitized systems work well, although to be fair, there are other place where semi-privatized systems have been very successful when well-implemented - the key differentiator between the successes and failures is often in the details which vary widely and make generalizations impossible.)

Amherst/Noho subway map

WANT (both the poster and the transit network... though I'm not convinced on the routes they chose - the blue, red, and yellow lines don't interact in the most logical pattern on the eastern side, there's no lines to North Amherst/Sunderland, and why'd they keep the Vermonter on the Amherst routing?)

"No road we build in Texas paid for itself"

"None." [via ViaArchitecture]
In Texas, he said that, on average, it cost the state 20-30 cents per person per mile to build and maintain a road to the suburbs, yet drivers only pay on average 2-3 cents per mile through the gas tax, vehicles fees, etc.

You do not want to get me started on this funding problem and the inherent unfairness to competing modes of transportation rant...

the predictability of spontaneous footpaths

These unplanned 'rule-breaking' footpaths that cut through open grass and quickly wear to a regular hard-pack earth are highly predictable and seen in exactly the same patterns worldwide. It's not a new phenomenon, or one that hasn't been studied in depth, but it's been largely ignored outside of academic settings. Just at UMass I photographed some dozen or so of these established informal paths for an anthropology class in under a half hour of looking. The problem is that the people designing and maintaing the formal paths never seem to take into consideration the realities of how people walk and refuse to compensate for them. Instead of providing adequate paths every year the same established footpaths are reseeded and roped off in a frustrating exercise of futile ignorance.
