new york times: how to be confused about transit

Lisa Margonelli's opinion piece in today's New York Times, "Thinking Outside the Bus," is a must-read, and not just for its important stories about small-town public transit development and the private van initiatives in New York.  It's also useful as an illustration of how people often imagine false links between unrelated ideas, and the role of emotive words and images in making these falsehoods seem real.

Everyone does this, so it's important to understand how it works.  Journalists especially must understand how this works, if they want to go beyond quick "good and evil" stories and actually explain an issue fairly.

The article begins with the story of Pam Boucher, a carless woman in the small town of Brunswick, Maine who was stranded until the advent of a small, intimate bus system:

Now in a wheelchair, Boucher calls me from a bus stop, where she’s waiting with a friend. The bus has changed her life, she says, giving her independence, control over her time and the ability to socialize. “I take it at least once a day. Sometimes three times.” She meets friends on the bus, takes herself to her medical appointments, and goes shopping for groceries afterwards. A few months ago the bus extended its hours into the evening to accommodate more commuters; she can now shop for groceries in the evening if her day has been spent at medical appointments.

And this bit is important:

“Doug’s the driver. He’s really good to me. He’s knows my condition and that I sometimes forget where I am.”

Brunswick's local buses, in short, are geared to people with special needs, as small-town transit systems often are.  The emphasis is on ensuring access for these people and providing them basic mobility in their community.

These systems are absolutely laudable.  I've helped design several of them myself.  But they are intrinsically inefficient, in terms of passengers service per unit of public cost, because the effort Doug takes in making sure Pam's needs are met requires a lot of Doug's time.  Suppose that on average, he spent six minutes taking care of each customer's needs, counting the time he's driving.  That would mean he'll never be able to serve more than 12 people per pay hour, which is very, very low by urban transit standards.  Serving special needs is a good thing to do, but it requires lots of staff time per passenger, so it will always have a very high cost per passenger.  Unless: 

Unless you pay the drivers less.  Margonelli's next story is about the emerging minibuses of New York, an important private sector initiative that's generating high frequencies of service on some streets using vans on fixed routes, where the van companies can quickly invent new routes as demand seems to require.  The genius of these buses is that they tolerate lower ridership (mandated in fact by their small size) but they can do this because the drivers make much less than unionized transit agency labor.  These vans may be innovative for New York but they're actually the normal way of doing business across most of the developing world, where low prevailing wages allow for high volumes of small-bus transit.  These systems are often not organized in the way that developed-world public transit is; often they feel more like taxis with multiple passengers.  But their sheer abundance, made possible by low wages, makes up for that deficit.

(There are intermediate models, by the way.  Vancouver's transit agency runs small buses, the Community Shuttle, at 50% of the cost of running big buses.  That lets the small buses be more abundant, reaching deeper into low-density hills than big buses could afford to do.  This didn't require the private sector, just a negotiation with the union based on the obvious fact that driving a small bus with few passengers is an easier job than driving a big bus with many.)

So is Margonelli really a ferocious right-wing union-busting capitalist?  No, she's just unclear on transit's basic geometry and economics.  Note this strange move:

America’s famously car-dependent culture strands the Pam Bouchers among us: those too old, too young, or too sick to drive cars. Overall, only 5 percent of Americans use public transit to get to work and that number is somewhat distorted by the huge numbers of people in cities who commute by subway, train or bus. Outside of metropolitan areas, the number of Americans taking public transit falls to just 1.2 percent. With so few people on the bus, schedules become infrequent and inconvenient, and ridership drops further.

The "huge numbers of people in cities" are distorting the national transit data?  Margonelli is clearly interested only in small town and rural transit, where she would like to raise that 1.2 percent figure.  Personally, I'm all for small town and rural transit, but only because of my own social-democratic beliefs about an inclusive society; unless you want developing-world wage rates, it's definitely not an efficient way to raise nationwide mode share.   That goal will be served only by focusing on places that transit can serve cost-effectively, carrying many people with few drivers.  That means cities, and a few other dense transit-oriented places like university towns.

Margonelli wants to somehow tie the social-service imperative in small towns in rural areas to the national challenge of increasing ridership, but the "low hanging fruit" for huge ridership increases is in the cities.  Our cities still have many places where the development pattern creates high potential demand for transit that isn't being well served.  If we were engaged in a national struggle to increase the usage of transit overall, that's where the big wins are. 

So let's come back to the issue of images and emotive words, and the way they help sustain confusion.  One thing happening in this story is that the human interest in Pam Boucher makes the author think that solving Pam's problem is an efficient way to serve national ridership goals.  This is just mathmatically false, becuase social service needs require lots of driver time per customer and the essence of efficient transit is minimizing driver time per customer.  Neither objective is bad, but they're different objectives.  If giving every customer five minutes of attention were the key to efficiency, corporations would still have human beings answering every customer's call.

But there are also three emotive words at work in this rhetoric.  One is "bus" as used in the article's title, "Thinking outside the bus."  The other two are in this passage:

Conventional wisdom says that the way to create or improve public transit is to invest billions to engineer rails, trains and buses. But the Brunswick Explorer [the new service that Pam Boucher uses] is one of many innovators that are seeing transit as more than an engineering problem and trying to  build transit that meets the needs of its residents.

You see them:  conventional wisdom and innovator.  This tired good-and-evil frame is routinely stamped onto all kinds of journalism about sustainability issues.  I wonder how many journalists could even write an article on these topics without using it.

Look at that word innovator or innovation.  We hear it all the time.  It means "having an idea that I personally haven't heard of before."

If don't know much about transit, many old and well-tried ideas will strike you as innovative.  The Brunswick, Maine transit system is laudable, but this kind of problem-solving focused on senior-disabled needs has been going on for decades.  It's a very localized, specialized process that's different in every town.  It's beautiful to watch and be a part of.  But the basic frame of the problem: the costs of service, the patterns of service that work in a small town, North American wage expectations, the opportunities for savings through communications and through merging existing operations — all this has been worked on for decades and solutions like Brunswick's have been created in many places.  Brunswick has tread a well-researched path; locally it's an innovation, but it's not more innovative than hundreds of similar systems.  Again, the word innovation reflects the writer's ignorance about the field.

If transit professionals seem cold to "innovative" proposals, it may because they're stuck in the mud.  But it may be because they know their field, have heard this proposal twenty times already, and understand the ways it works and doesn't work.  They may also understand that the "innovation" meme is really a way to evade a real, hard question, such as the appropriate levels of wage for transit workers.  Nobody wants to talk about that; it's much more fun to praise private-sector models like the Flatbush vans.  But if you call those vans innovative, what you're really saying is:   "I've never used public transit in the developing world, where this idea is routine, so it's new to me."  (You're also saying: "Drastically lower driver wages are a great idea.")

Remember, in North America, most of what looks "efficient" and "innovative" about "private sector" transit is simply liberation from the negotiated wage rates that bind virtually all public transit operators.  Transit costs are driven by the cost of labor, so if you make labor cheaper, many things are possible.  Calling these services "innovative" is taking your eye off the ball, and needlessly slandering transit experts as purveyors conventional wisdom just because they've heard the idea before.

As for "bus" as an image of constrained thinking (in the title, "Thinking outside the bus"), it's understandable, though increasingly archaic.  The crowded, constraining, poorly ventilated bus does feel like a box and thus as a good metaphor for mental imprisonment or "conventional wisdom".  (Remember the film Speed, or the pilot of Six Feet Under?  Both used a bus that was older than most buses on the road at the time, intentionally playing to a stereotype of buses as primitive.)  Yet all the solutions Margonelli proposes are also vehicles on tires.  "Bus" is a large and diverse category, which makes it useless for talking about what matters in transit.  The word says nothing about speed, duration, frequency, and reliability, nor does it address labor cost, which determines how much of these things you can afford.   "Think outside the bus" if you must, but as Margonelli's examples show, you're still likely to end up with one.

UPDATE:  For further entertainment, see Eric Jaffe today in the Atlantic on the "entirely new transit concept flexible bus services," which have been around for decades.  I personally was designing them (and sometimes ripping them out) almost 20 years ago. 

 

walkscore’s new apartment search functions

Walk Score, an admirable Seattle company that invented the "Walk Score" now widely used in the US real estate business, now has an improved app for their transit travel time tool.  That tool, which I use in my own definition of "personal mobility," shows you how far you can travel on transit from a chosen point in a fixed amount of time.  For example, here's how far you can go in 15, 30, or 60 minutes from San Francisco Civic Center, at least on agencies that participate in Google Transit:

6a00d83454714d69e2011571e07ffe970b-800wi
You can find something similar at Mapnificent.net.

Walkscore now has a fine new set of presentation tools that combine this information with real estate listings, so that you can search available apartments based on commute time to a destination of interest.  Couples can even search for locations that optimize both of their commutes.  For example, if one of you works in downtown Seattle and the other across the lake in downtown Bellevue, Walk Score discovers that if you want to equalize your commutes, you should live in the University District, where the blobs of access from the two workplaces overlap. Walk Score will even show you available apartments there.

2 pers commute

(Of course this service needs to be expanded beyond rentals.  Some people who are buying a home may care about similar criteria.)

All this is a step toward a more universal use of this tool that allows anyone (people, businesses, institutions, government services) to see the transit access consequences of where they choose to locate.  Many places are simply inaccessible by any efficient form of transit, so people need tools for avoiding those places if they want transit to be part of their lives, or that of their employees, customers, or clients.  That's especially important because some of these places are cheap, but may not be as cheap as they look when you consider the transport costs they impose.

I'm also interested in using this tool to generate a more factual two-digit "Transit Score" than the one Walk Score currently promotes.  More on that here.

Transit Planning for Fictional Universes: It’s Serious Business

As longtime readers know, I would reject the claim — repeated today by Benjamin Kabak at Second Avenue Sagas — that “in fictional universes, subway systems do not have to make much sense.”  So I would not be as quick as he to excuse the incoherences of the newly announced Gotham Transit Authority Map:

Gotham-gta-mapjpg-12426d2c7c8a75a9
While Batman himself has other transport options, many fictional people are going to need transit to assemble the necessary crowds and populate the alleys and crevices of his plots, and those people certainly need better than this.

Perhaps I nitpick because I was raised on higher-grade science fiction and fantasy, in an era when authors felt compelled to think about every relevant dimension of their world.  In those days, you didn’t worry so much, while exploring the fictional world, that if you leaned on a tree it might collapse like a flimsy cardboard set, revealing a blank space that the author hadn’t seen fit to imagine.  J.R.R. Tolkien knew all the personalities and travails of every king for the last several millennia, and of many mythical ages before that.  You could at least expect an urban imaginer to be sure the transport system made credible sense.

Even more important than the fictional universe, of course, is the hypothetical one, where even more care is required!

Are you an aspiring science fiction writer or screenwriter?  If so, have you hired a transit planner yet?

australia / new zealand readers!

Cover thumbMy book may well be out in Australia/NZ even before it comes out in North America.  NewSouth Books, the book's Australia/NZ distributor, plans to print books in Sydney instead of waiting for them to make the long flight.  This saves carbon emissions while getting the books out faster, probably by mid-December at the latest.  They'll also be offering a 20% discount for Aus/NZ customers who order off their site.  You can pre-order now.  (It encourages them to print more!)

Here's New South's flyer promoting the book, which you're welcome to print, share with friends, and leave modestly lying about:  Download Human Transit flyer(2).

Back to usual programming soon!  (Finger is better, thanks.)

 

san francisco: frequent network map refined

SF Cityscape has done a refinement of their excellent frequent network map for San Francisco, one that highlights the basic structure of the network that's useful for impatient people at all times of day.  You can download the full GIF and or PDF here.  A slice:

Sf cityscape map
The map is so cool that I feel liberated to nitpick.  Some other basic principles for maps of this type, worth considering:

  • Limited stop service (numbers with an L suffix in San Francisco) is substantially faster than local-stop, so I think it deserves its own color, possibly shading gradually to the local color when the limited segment ends, as 71L does west of Masonic.  A separate color would also clue in the viewer that those lines stop only at the points indicated, while locals stop at more stops.
  • To further clarify the previous point, I'd come up with a really tiny stop symbol to mark all stops on local-stop services — maybe labeling them in smaller print or not labeling them at all.  This would give a visual indication of frequency of stops that would give an accurate view of relative speed.  You really do not want to ride all the way across the city on Line 1, which stops every block or two.  Such a notation would help the limited stop services — which really are useful for going all the way across the city — stand out more effectively.
  • The mapmaker has followed the transit agency's practice of marking only wheelchair-accessible stops on the surface streetcars such as N.  In fact, these line stop every 2-3 blocks, so I would be inclined to mark all stops, maybe using a notation like that above.  I'd also advocate separate maps highlighting issues that matter to disabled persons.  (Has any transit authority published special maps or online map layers specifically for people in wheelchairs etc, as an alternative to including all this information on a main system map?)
  • I would also be inclined to emphasize that surface stops around a rapid transit station are indeed AT that station, so for example I would extend the Van Ness and Civic Center station bullets to encompass the adjacent bus stops rather than giving those stops separate coordinate names.  This is especially important on schematic maps because the user is wary that a small space on the map might be a large distance.

But again, I can nitpick usefully only because it's a really great map!

toll roads coming on?

The new US initiative to allow states to toll interstate freeways has to be good news, in the long run, for sustainable transport.  The money will go for urgent repairs to those freeways, which is fine with me; the key benefit is to get drivers used to the notion of road tolling again, as it's likely impossible to achieve true decongestion pricing without something that looks like road tolls. 

The initial legislation allows just three projects but they are obviously meant to demonstrate the idea and lead to wider rollout.  Virginia, impressively, is proposing to toll parts of Interstate 95, probably the state's single most important artery. 

At the opposite extreme, Arizona proposes to toll Interstate 15, and on that I have a question for journalists.  The Los Angeles Times writes:

A proposed toll on a 30-mile stretch of Interstate 15 in Arizona is drawing opposition from neighboring Utah.

"If Arizona has been negligent in its maintenance of I-15, it should not try and foist its responsibility onto highway users or neighboring states who already pay into the system with their own tax dollars," Utah Gov. Gary R. Herbert said in a recent statement.

Arizona's Interstate 15 segment is later described as being "in the state's northwest corner," but why not state the obvious?  It's not connected to the rest of the state, Arizona has no towns on it, and it's frankly a bit hard for Arizona to get to.  It's the segment between Mesquite, Nevada and St. George, Utah in this image (click to sharpen):

Az nv ut

So if a journalist can't print a map, they could at least clarify that virtually no Arizona residents use this highway, which would be enough to make the politics clear.  Arizona's toll-road bid is the opposite in spirit of Virginia's, designed exclusively to soak out-of-state drivers.  Given the road's location, and its irrelevance to most Arizonans, the positions of all sides are totally understandable.  Would that really spoil the "conflict" that journalism supposedly needs?

 

 

we have a date: “december 5 or so”

WalkerCover-r06 croppedI just signed off on the very, very last proofs of the book.  Island Press's copyeditor has advised me to expect books out by "about Dec 5 or so."

Have you read the introduction and table of contents?  If not, please have a look now.  I hope it will be clear that the book is unique in trying to make transit choices clear to the interested general reader, including elected officials, advocates, and professionals in related fields.

I will be based in Portland throughout Dec, Jan, Feb, Mar, but also have trips planned in that range to Auckland NZ, eastern Australia, Washington DC, Seattle, and possibly South Florida.  Other trips are possible depending on honoraria etc.  I'm obviously keen for opportunities to do public lectures sponsored by reasonably prominent organizations or institutions.  If you know one, please let them know.

And if you've already decided you're looking forward to reading it, why not preorder?  It's also on Amazon, and quite possibly your favorite book website.

 

the build vs. maintain problem

A good article at Strong Towns highlights a structural problem with how the US does Federal infrastructure funding:

We can get money from Washington to build new infrastructure, but it is really difficult — if not impossible — to get money from Washington to maintain existing infrastructure.

The article explores the problem in the context of Minnesota bridges, noting that Federal funding is going forward for a bridge expected to serve 16,000 cars a day while Minnesota is unable to fund maintenance for existing bridges carrying 2.4m cars a day. 

One solution has been for the Federal funder to demand evidence of a maintenance funding commitment by the state/province, but such guarantees would need to be eternal, and eternal commitments are very hard to enforce.

Canadian and Australian readers who dream of a bigger central government role in infrastructure funding, this caution is for you!  Think hard about what you want to federalize.  If you're going to demand federal funding for infrastructure, you might want to demand life cycle maintenance funding instead of just building things that states and provinces can't afford to maintain.  Think, too, about this.

strategic minds vs physical objects

Sunday I sliced off the very tip of my right index finger while searching for a pair of scissors in the suitcase.  The doctor called it a "guillotine wound." 

As a touch typist, I've been contemplating topics that might be discussed without using the letters J, H, M, N, U, and Y, but the more likely outcome is a week or two of hiatus.  Send brilliant guest posts!
