My Washington Post Piece

It’s here.  Twitter’s favorite quote from it is:

Cities have relatively little space per person. Cars are big. Big things don’t fit in little spaces.

In short, it’s all, always about geometry, which technology will never change…

To predict the future, we need to think carefully about what’s permanent and what may be fleeting. Fashions and tastes are fleeting, but geometric facts are permanent. Fifty years from now, our sense of what’s sexy or hip or green will be very different, but big things still won’t fit in small spaces.

 

Luxembourg: A New Official Frequency-based Map

Maps that help people see which services are coming soon are remarkably rare in Europe, for a variety of complex reasons.  Some European systems have such high frequency overall that it may seem unnecessary, but there are usually still significant frequency contrasts that matter.

Now, there’s a great example out of Luxembourg.  The Paris-based Serbian designer Jug Cerovic has been featured here before, for his interest in making networks clearer by emphasizing a core geometric idea.  Not just for beauty, but as a way of combatting the mental overload that complex maps can cause.

Luxembourg’s transit system has just rolled out an official network map by Cerovic.  It highlights frequency with wide lines, including such details as how wide frequent lines split into narrow infrequent ones.  (Detailed PDF is here.)

Obviously this is a diagram, seeking network clarity rather than precise fit with local geography. The core geometric idea is the pentagon, a feature of the Luxembourg CBD that he uses, but not to excess, in arranging patterns. He explains his design process here.

Keys to Great Airport Transit

Toronto’s new high-fare, elite train between downtown and the airport is a failure in ridership terms, so it’s a good moment to talk about transit to the airport in general.

This critique by Cherise Burda of Ryerson University, one of the Toronto line’s few regular riders, pretty much sums up why the Toronto Union Pearson Express is doing so poorly:  Fares too high (CAD $27.50 one way) for a line that just doesn’t connect the airport to enough places.

Do you think that specialized airport trains are the key to high transit mode share to an airport?  Think again.   What matters is not just the service to downtown, but the whole transit network and the airport’s position in it.  Where can you get to on that network, and how soon?  (A true assessment of this issue would have included bus services too, of course.)  London’s Heathrow, for example, has a high-fare express train very much like Toronto’s, but it also has a slower train that makes more stops for a lower fare, and a subway line that makes even more stops and serves even more places.  Those lines connect to more services, and are therefore more useful to far more people.

Basic math:  1000 airport employees using an airport service every day are more ridership than 100,000 air travelers using it, on average, maybe a couple of times a year.

This is the simple reason that airport transit politics are so frustrating.  Everyone wants to believe in transit to the airport, because they might ride it a few times a year.  But to create a great airport train (or bus) for air travelers, you have to make it useful to airport employees too  That generally means a service that’s an integral part of the regional transit network, not a specialized airport train.

The other key issue is that most airports are cul-de-sacs.  It’s hard for a line to continue beyond the airport unless it’s underground, and this is another huge limitation on an airport service’s ability to serve a sufficiently diverse market.  If you can afford it, aspire to be like Sydney, whose rapid transit system tunnels under the airport so that it can continue beyond it without branching. And if you’re a rare airport like Seattle’s, where surface transit can stop at the terminal but continue onward, so much the better.

So again, here are the keys to great transit to the airport, for travelers and employees:

  • Total travel time matters, not just in-vehicle time.  Airports are citadels of impatience.  Travel time matters hugely, but travel time is not just in-vehicle time (the time you’ll see advertised) but total time including waiting.  That’s why the advantage of making few stops is wildly exaggerated. To accurately measure real travel time, add the in-vehicle travel time to half the waiting time, where the latter is governed by frequency. You may find that a more frequent train that stops more often (and is therefore useful to more people) comes out ahead even for the downtown-to-airport traveler.
  • Combine air travelers and airport employees on the same train/bus, and appeal to an economically diverse range of air travelers, not just the elite.  This is a case of the general principle that transit thrives on the diversity of trips for which it’s useful, not on specialization.  If elites want a nicer train, give them first class cars at higher fares, but not a separate train just for them.  (And as always, elite services are a good role for the for-profit sector.)  As always, the more people of all kinds you can get on a train or bus, the more frequently you can afford to run it, which means less waiting, and the lower the fare you need to charge.
  • Connect the airport to lots of places, not just downtown, by providing a total network.  It’s the total transit system at the airport, not just the airport-downtown express line, that determines who can get there, and how quickly.  And the total network requires connections — another reason to care about frequency.
  • Don’t interfere with the growth of other services.  Airport terminals are still not huge destinations by citywide standards, so don’t sacrifice other major markets to serve them.  Toronto’s airport train, for example, not only carries few people but creates issues for higher-ridership services with which it shares track. Another common problem is the branch into the airport that cuts frequency and capacity on a mainline, even though the mainline’s demand is much higher than the airport’s (San Francisco, Vancouver).
  • If you can afford it, go via the airport instead of terminating there.   Most airports are large-scale cul-de-sacs, and like every cul-de-sac, they say: “I want only as much transit service as I can justify all by myself.”  So if you can tunnel under the airport and serve it on the way to other places, as in Sydney, you will often end up with much better service for all your airport users, employees and travelers alike.

 

 

How Vague Should Plans Be?

How specific or vague should a transit plan be, before it’s announced?  And what kinds of specificity matter?

It’s easy for a journalist to say that a plan is short on specifics, but all plans are short on specifics.  If included every detail, you’d have construction drawings, escrow arrangements, employee work shifts, and so on. But that’s a lot of work, so you don’t do it until you’re sure you want to proceed.

Good planning starts at high altitude and proceeds downward through levels of detail until it’s ready to happen “on the street.”  In transit, for example, it’s best if you first do big-picture city or regional plans, then implement these through local area or corridor plans, then implement these with more detailed design, then implement those with construction drawings or timetables.  Finally you implement those by actually building or operating the proposed thing.

As you descend in altitude, you may hit a fatal flaw. You may have to back up to a higher altitude to see a way forward.  But without altitude at first, you can’t see the big picture, and if you go into detail too soon, there’s a risk that the whole point of the plan gets lost as you quibble over a parking space.

So when a plan is announced, don’t jump to quickly to saying it lacks enough detail.  We planners spend a lot of time trying to figure out exactly what to be specific about, and what can be left vague for now.  Not out of any desire to mislead, but because it’s impossible to talk about all the details at once, and too expensive to study them all at an early stage.  We rely on well-honed instincts:  Which details are most likely to erupt into a problem — technical or political — down the line?  Which other details can be noted and honored but left to a later phase to refine?  These are some of the hardest calls that planners make.

Preliminary BQX AlignmentFor example, I sympathize with the proponents of the recently announced Brooklyn-Queens Streetcar in New York, including the estimable Sam Schwartz, (“Gridlock Sam” at the New York Daily News) who advised the Mayor on the project and is also a leading advocate.  Since it was announced a couple of weeks ago, civic leaders have lined up to support it but many leading transit advocates and urbanists have challenged the project, or at least raised hard questions about it.

I have been on both sides of these issues.  But while every plan is going to be vague, it’s important to notice which parts are specific and which parts are vague, because this can signal something important about how the plan is likely to change as it goes through later stages of refinement.

The mayor’s press release, including the map shown here, spends most of its length talking about why a certain area needs transit, and asserts that a streetcar is the answer.  It assumes that “streetcar” will make us like the project before we know much about what it does.  The release does include a set of travel time claims, but it doesn’t say much about:

  • Frequency, which governs how long you’ll wait before you can even begin.  (An ideal travel time estimate would always include half of that wait.)
  • Connections, notably which subway lines the service would connect to.  The curves on the map suggest but don’t imply any particular path, which would run on particular streets and connect with particular subway stations.  I’m sure I’m not the only person who spent a while on Google Earth trying to figure out what these sensuous curves might mean in reality.
  • Reliability, which generally requires exclusive right of way.  The mayor’s press release says “majority of the line” is protected from car traffic.  Other sources have told me anything from 70% or 100%.   If it’s not 100%, it matters which 50-99% we’re talking about.  Transit advocates have good reasons to be concerned about this.  There are cases where transit can mix briefly with traffic and not be much affected – typically when the traffic is very low because the street is just for local access.  But what tends to emerge out of the political process is exactly the opposite: Where traffic is bad, it’s politically hard to take a lane for transit, so transit ends up with exclusive lanes that disappear precisely where they are needed most.  This is a very important part of the history of both streetcars and Bus Rapid Transit in the US.
  • Fares. What will they be, and will it be free to transfer to the rest of the transit system, so that people can get to the 95+% of the city that’s not on this line?

If you just love streetcars, and want a streetcar, then these sound like the petty concerns of people who can’t see or trust your grand vision.  But if you want an efficient transit network that liberates people to access opportunity, these things are paramount.

If the main goal of a project is to build a piece of technology, this sets up a risk that when hard choices have to be made down the line, the speed, frequency, and reliability will be sacrificed later in the project, as the “details” are being worked out.    Suspicion about this is understandable, when you consider how slow and unreliable many US streetcars have turned out to be.

So how vague should a plan be?  It’s a tough call.  You have to be vague about something, but from that, people may reach judgments, fair or not, about what your priorities are.

For Reporters Disparaging Transit Projects, “Far” Isn’t Far

If you’ve ever wondered what well above and well below mean, as opposed to far above and far below, Dan Weikel and Ralph Vartebedian at the Los Angeles Times have quantified it for us, in an article about the California High Speed Rail project.

Rail officials also say the latest cost estimate for the entire 500-mile project has been reduced from $68 billion to $64 billion, well below the $98 billion projection from several years ago, but still far above initial estimates of less than $40 billion.

I’d always assumed that  far was further than well.  But no, by their math, well is $34 billion but far is as little as $24 billion.   Well is further than far.

So now, anytime someone uses far or its relatives to imply extremes — “the furthest corners of the earth” etc,, you can ask:  Sure, they may be the furthest, but are they the wellest?

Is Infrastructure Still about “Awe”?

Allison Arieff in the New York Times thinks the problem with our infrastructure planning is lack of “awe”:

[Dave] Eggers’s proclamation that the Golden Gate [Bridge] is beloved because it’s outrageous and weird may fly in the face of just about everyone’s attitude about infrastructure, but it also gets at exactly what we should be feeling about bridges and tunnels.

Awe.

American infrastructure is deferred home maintenance on a massive scale. We just keep putting it off until something major — and often catastrophic — happens, and then it ends up costing twice as much as it would have had we taken care of it proactively. This is a bad strategy — yet it’s the strategy that seems to define United States infrastructure.

There is no awe. There are issues of structural integrity. There are mind-blowing cost overruns. Accidents. Sinkholes. Problems with bolts.

The first design proposed for the Golden Gate was, writes Eggers, “the strangest, most awkward and plain old ugly bridge anyone had every seen … people compared it to an upside-down rat trap.” (Here is what it looked like.) The public demanded something better — and they got it.

A century later, we’ve lost our collective faith in the power of great projects like the Golden Gate, not to mention our trust in the government to fix a pothole on time and on budget, let alone create an inspiring bridge. How can we restore that faith in possibility?

I’ve lived in cities with awe-inspiring infrastructure (San Francisco, Sydney, Vancouver, Paris) but now I’m based back in my original hometown, Portland.  And Portland is the perfect riposte to Arieff’s obsession with awe.

Portland is “awesome” but not the least bit awe-inspiring.  If you want to gape at the spiritual grandeur of human works, strike us off your list.   Our monuments, bridges, and major buildings are all modest and even gentle.  Many are beautiful but none are magnificent.  Our city is so human-scale that we just don’t need to build very big things.  For some related reason, we also have no need for a dramatic, soaring tower with a rotating restaurant and observation deck.

We don’t need the tower, because we have hills and mountains.  Portland manifests a particular reaction to a natural setting: not the desire to compete with it by creating infrastructure of comparable grandeur, but a humility toward it, a happiness that comes from dwelling in its shadow, and letting it give us all the awe we may need.

Nature now awes us in another respect: We’ve been warned to expect an appalling earthquake in which thousands of us would probably die, because our infrastructure isn’t designed to survive it.  Of our 12 river bridges, for example, only the newest one is pretty assured of not collapsing (a second is now under construction.)  Countless brick and concrete buildings and highway ramps are likely to go.  Arieff dismisses the small mindedness of “problems with bolts,” but bolts are exactly what’s going to kill us.  Telling Portland to spend money on awe instead of bolts could be a pretty direct threat to our lives.

The bigger lesson of Portland is you can build a great city by learning to take pleasure in the actual functioning of things, and the resulting liberty and happiness of people.  Pioneer Courthouse Square, for example, is pleasant but not awe-inspiring, and the real reason to love it is that it’s so massively useful for all kinds of happy and liberating purposes.  In our better moments, we feel that way about our transit system.  Function, especially when it engenders liberty and opportunity as functional transit does, can be a higher delight than awe, and a more durable one.

The other problem with awe is that it’s so often about the power of some people over others.  Versailles and Imperial Vienna are awe-inspiring, but the awe has a purpose: to make you accept your place in a hierarchy of power and privilege.   The medieval cathedral was a gathering place (like our civic squares) and an honest monument to human spirituality, but the awe you feel there is also meant to make you defer to the authority of your local priest and the Pope.   Awe and intimidation are the same thing in slightly different light.

So perhaps we should be suspicious of awe, with its reverberations of power and grandiosity.  Delight and pleasure are are better aesthetic selling points, but at our best, as in Portland in its better moments, even these things arise from functionality, safety, usefulness to vast spectra of people.  And the infrastructure that best does all those things may not be awe-inspiring, in the same way that Portland isn’t.

Let us create affordable and inclusive delight wherever we can find it, but let’s be sure that advocates of function are in the room, reminding us of the urgent human rights and ambitions that only functional infrastructure can support.  Appeals to awe, in particular, are not how we build that room.  Historically, awe’s purpose has mostly been the opposite: to keep people outside, mouths agape at the magnificence, while their betters plan their destiny.

Richmond: Bus Rapid Transit Line Approved

The Richmond (Virginia) city council has approved plans for a Bus Rapid transit line running east-west through the core of the city — the starting point for a more robust transit network for the whole city and potentially the region:

richmond pulse

Like all starter lines, it focuses on a small part of the city, and these projects always raise questions about the city-wide benefits. What’s in it for you if you don’t live or work near the line?

One answer to that concern is that a good core transit line produces all kinds of benefits across the city. By running a busy corridor more quickly and reliably, resources are freed up to run more effective local services.  Like all rapid transit lines, this one will depend heavily on improved local bus service, and improved local bus service will mean better mobility for people not on the rapid line.

That’s all very nice in the abstract, but what’s the specific plan? Fortunately, the people of Richmond will have the chance to help forge that plan in the coming year. We are now working with City of Richmond, GRTC and the local office of planning firm Michael Baker International on the Richmond City Transit Network Plan.  This effort, to develop specific ideas for a better local bus network, will include many opportunities for citizens to consider the choices themselves and share their ideas and priorities.

So if you’re worried about whether your neighborhood will be well served by the future transit system, get ready to join a conversation about exactly that.  Plans for major transit infrastructure are never total transit plans, any more than a main street is a total street network.   The real network planning starts now.

 

 

How to Read the Best Anti-Transit Writing

Randal O’Toole has made quite a career of being America’s leading anti-planning planning expert, and especially its leading anti-transit transit expert.  His biases are obvious but his he knows his topic and can make good points, so he’s sometimes worth reading a little closer.  If nothing else, transit advocates need to hear more arguments from outside their own media bubble, just as everyone else does.

Today he has a blog post asking if we are approaching “peak transit.”  It’s a concise and readable display of his insights, techniques, and biases.  So if you’ve never read O’Toole before, let me take you on a quick guided tour:

“Billions spent, but fewer people are using public transportation,” declares the Los Angeles Times. The headline might have been more accurate if it read, “Billions spent, so thereforefewer are using public transit,” as the billions were spent on the wrong things.

The L.A. Times article focuses on Los Angeles’ Metropolitan Transportation Authority (Metro), though the same story could be written for many other cities. In Los Angeles, ridership peaked in 1985, fell to 1995, then grew again, and now is falling again.

O’Toole nicely summarizes the two fallacies that drove the sadly-too-influential LA Times piece.  The first is that Los Angeles ridership is on a clear downward trend based on 2015 data, which is an illusion created by the Times reporters’ selective citation of data. [JW update: The trend is clearer in 2017, which doesn’t change the fact that 2015 data didn’t support it.]  The second, more basic fallacy is that short term ridership is the proper metric for judging long term investments. That’s like saying that because the corn you planted wasn’t ready for harvest a week later, it was dumb to have planted corn.

Sometimes O’Toole is Right

But just as you’re ready to dismiss O’Toole, there’s this:

Unmentioned in the story, 1985 is just before Los Angeles transit shifted emphasis from providing low-cost bus service to building expensive rail lines, while 1995 is just before an NAACP lawsuit led to a court order to restore bus service lost since 1985 for ten years.

This is true, especially if you’re careful, as O’Toole is here, not to assert that the lawsuit caused the change.  (There are several explanations for why Los Angeles transit leaders started focusing on bus improvements in the late 90s, and rehashing them is not helpful to consensus-building today.)  Let’s look again at that chart from the LA Times article.

la-me-g-ridership-slump-20160126-1

Los Angeles ridership fell when bus service was being cut early in the rail program, then rose when bus service was being rapidly improved.  Since 2005, when the balance of attention on rail vs bus has been closer to equilibrium, ridership has been basically flat, going up and down in a small range that is trivial compared to the great swings of the 1985-2005 period.  The little downtick at the end of the chart, on which the Times reporters hang their narrative, is obviously not enough to be significant yet, at least when viewed at this scale.

But this does not mean, of course, that “billions have been spent on the wrong things.”  This would require that we share O’Toole’s belief that short-term ridership was the purpose of the rail investments, which it was not.  Declaring transit to be failing at goals it is not pursuing is extremely common in anti-transit commentary.  Another common example of this is here.

The (Real) Ridership-Counting Problem

Then O’Toole makes another almost-good point:

The situation is actually worse than the numbers shown in the article, which are “unlinked trips.” If you take a bus, then transfer to another bus or train, you’ve taken two unlinked trips. Before building rail, more people could get to their destinations in one bus trip; after building rail, many bus lines were rerouted to funnel people to the rail lines. …

Higher transfer rates are not strictly a result of rail; they can arise from good bus network designs as well.  But the “unlinked trips” issue is real.  It’s one of those things that makes sense to the transit industry internally but not to the public to whom we have to explain our work.

The problem dates back to a time when completed journeys (“linked trips” in the comically opaque jargon of technocrats) were just impossible to count without expensive manual surveying.  This is still the case in many agencies.  People flash monthly passes or day passes at the driver, for example, and even if the driver counts this as a pass, there’s no record of whether the rider was beginning their journey or making a connection.  As automated ticketing comes in, it is getting easier to count completed journeys.  But the transit data world is very concerned with comparability — this is the whole point of the US National Transit Database — and this creates a motivation to use only data that all transit agencies can easily report, even the lowest-tech ones.  This is a real issue.

Of course, a rising transfer rate isn’t evidence of failure. But it does distort the real outcomes if a count of boardings (“unlinked  trips”) are reported as though they were a count of human beings reaching their destinations.  They are not.

Judge by Real Investments, and Real Goals

Transit ridership is very sensitive to transit vehicle revenue miles. Metro’s predecessor, the Southern California Rapid Transit District, ran buses for 92.6 million revenue miles in 1985. By 1995, to help pay for rail cost overruns, this had fallen to 78.9 million. Thanks to the court order in the NAACP case, this climbed back up to 92.9 million in 2006. But after the court order lapsed, it declined to 75.7 million in 2014. The riders gained on the multi-billion-dollar rail lines don’t come close to making up for this loss in bus service.

This is right, too (except for the debatable causal claim of “thanks to,” which I won’t touch).  Yes, you have to evaluate ridership in the context of service quantity, and what matters is not what is built but what is operated.

Contradictory Accusations

But then, we get an old O’Toole favorite, that transit agency “officials” are incompetent:

The transit agency offers all kinds of excuses for its problems. Just wait until it finishes a “complete buildout” of the rail system, says general manager Phil Washington, a process (the Times observes) that could take decades. In other words, don’t criticize us until we have spent many more billions of your dollars. Besides, agency officials say wistfully, just wait until traffic congestion worsens, gas prices rise, everyone is living in transit-oriented developments, and transit vehicles are hauled by sparkly unicorns.

Imagine if we had built the Interstate Highway System with this attitude.  Oops, we just spent billions on a freeway to newly developing suburbs, but not many people are driving on it yet because the suburbs are still under construction. Surely the O’Toole of the day would have said that those highway planners are fools!

There’s another contradiction here, which pervades all of O’Toole’s work I’ve read.  O’Toole can’t decide if (a) transit is a bad idea or (b) transit is just badly planned and operated.  If transit is run by idiots, as he often implies, then logically its performance says nothing about transit’s actual potential.  On the other hand, if transit is a dumb idea, it would fail even if it were run by geniuses, which he advises it’s not.  He can never seem to decide if he’s against transit or against the people making decisions in transit agencies.  Logically, these two claims undermine each other.

The Heart of the Matter

We’ve arrived at what’s really at stake here in this obsession with short-term outcomes.   O’Toole begins from a deep hostility to the very notion of long-range planning, at least when done at the level of the city or community, and I hear this more and more from “conservative” voices in local conversations.  (I put “conservative” in scare quotes because the more I hear the word, the less it seems to mean.)  Sometimes I want to get some of these folks (especially older ones) into a room and just ask this:  “Close your eyes and visualize your grandchildren, or whatever children are in your family.  Are there any sacrifices you’d be willing to make so that they would have better lives, more opportunities, and generally a better world, even after you’re gone, even after you are no longer there to enjoy their gratitude?”

Most writers who self-describe as “conservative” these days, including O’Toole, seem to be starting from a clear no on this question, and presuming the same in their readers.  If it doesn’t pay off now, it doesn’t matter.  If you think about it, is the world view of the average thrill-seeking teenager, something most of us hope to grow out of as adults.

Transit investments will make no sense to anyone who thinks this way, so the best answer, I think, is to ask my question about grandchildren.  If the answer is no, there’s no point arguing.

O’Toole would probably respond that he’s only opposed to government long-range planning, not private-sector or personal long-range planning, but the real horror for him is that as the world is becoming more interconnected, prosperity depends more and more on collective outcomes.  Nowhere is this more obvious than in the rising economic importance of cities, the popularity of urban life as expressed in urban real estate values, and the impossibility of managing a  prosperous and inclusive city without effective government.

One of the most crticial things governments do, by the way, is involve affected people in decisionmaking.  Some folks may look back fondly at times when the private sector did most city planning and city building — as in the 1865-1929 period in the US.  Much of the developing world is like this today, and if anyone wants to argue that “great libertarian city” is not an oxymoron, that’s where they’ll have to look for case studies.  But these were and are oppressive places for vast majorities who are not connected to the power structure, and the developing-world cities that are trying hardest to improve themselves are doing so through strengthening the government’s role and competence.  The notion that a happy dense city can be generated solely from private profit-seeking has been tried, and I suggest you consult your favorite urban novel from the 1865-1929 period for reminders of what that was like.  Almost anything by Dickens will do, and so will Upton Sinclair.

Next up, another paragraph with which I can partly sympathize:

A more realistic assessment is provided by Brian Taylor, the director of UCLA’s Institute of Transportation Studies, who is quoted by the L.A. Times saying, “Lots of resources are being put into a few high-profile lines that often carry a smaller number of riders compared to bus routes.”

This is half right.  There are lots of great rail projects, but that list does not include projects that can only be promoted by categorically denigrating buses and their passengers, such as many of the new slow streetcars.  O’Toole is making a good argument against projects based on technology-fixations, but that’s not an argument against high-capacity projects like the Wilshire subway in Los Angeles, whose purpose is not just to improve transit there but to make many more people want to live and work there.  It’s certainly not an argument against Manhattan’s Second Avenue Subway or Vancouver’s Broadway Subway, where the necessary crowds already exist.

The Arbitrary Starting Year, and Other Statistical Absurdities

That, I’m afraid, was the best part.  From there on, O’Toole’s post goes downhill.  First, we get a pile of misleading but ominous statistics.

Los Angeles ridership trends are not unusual: transit agencies building expensive rail infrastructure often can’t afford to keep running the buses that carry the bulk of their riders, so ridership declines.

Ridership in Houston peaked at 102.5 million trips in 2006, falling to 85.9 million in 2014 thanks to cuts in bus service necessitated by the high cost of light rail;

Despite huge job growth, Washington ridership peaked at 494.2 million in 2009 and has since fallen to 470.4 million due at least in part to Metro’s inability to maintain the rail lines;

Atlanta ridership peaked at 170.0 million trips in 2000 and has since fallen nearly 20 percent to 137.5 million and per capita ridership has fallen by two thirds since 1985;

San Francisco Bay Area ridership reached 490.9 million in 1982, but was only 457.0 million in 2014 as BART expansions forced cutbacks in bus service, a one-third decline in per capita ridership;

Pittsburgh transit regularly carried more than 85 million riders per year in the 1980s but is now down to some 65 million;

Austin transit carried 38 million riders in 2000, but after opening a rail line in 2010, ridership is now down to 34 million.

Give O’Toole credit: When he tells us that ridership “peaked,” he’s confessing that he’s playing the “arbitrary starting year” game.  To get the biggest possible failure story, he compares current ridership to a past year that he selected because ridership was especially high then.  This is a standard way of exploiting the natural volatility of ridership to create exaggerated trends.  Again, the Los Angeles Times article that got O’Toole going made a big deal out of how ridership is down since 1985 and 2006, without mentioning that ridership is up since 1989 and up since 2004 and 2011.  Whether ridership is up or down depends on which past year you choose, which is to say, it’s about what story the writer wants to tell.

Then we get a real gem of absurdity:

Even where ridership is increasing, it’s decreasing. After building two light-rail lines, transit ridership in the Twin Cities has grown by 50 percent since 1990. However, bus ridership is declining and driving has grown faster than transit.

Well, of course bus ridership declines when you open high-ridership rail lines.  That’s because the rail lines, if they’re well designed, grow out of very high ridership bus lines.  Rail replaces those bus lines, shifting a large number of riders from bus to rail.  Maybe there is a larger story here about neglect of buses in the Twin Cities, but O’Toole doesn’t make that argument.

Ignore National Statistics

Anti-transit arguments can always take comfort in national statistics about transit, which count all of the rural and exurban population as part of the case for transit’s failure:

Whatever the service levels, transit just isn’t that relevant anymore to anyone. As I’ve pointed out before, more than 95 percent of American workers live in a household with at least one car, and of the 4.5 percent who don’t, less than half take transit to work, suggesting that transit isn’t even relevant to most people who don’t have cars.

Again: National statistics about transit are meaningless, because transit works or doesn’t for entirely local reasons.  Most Americans don’t live in places where transit works really well — dense cities, mainly — so of course not many Americans use transit.  This says nothing about transit’s popularity in the places to which it’s suited.

Did You Know that You Don’t Exist?

You should also be offended whenever a minority of any kind, including the minority who use transit, is described as not counting as “anyone,” as O’Toole does in the first sentence in that last quotation.  Because most Americans don’t ride transit, O’Toole says, transit isn’t relevant to anyone.  In case you weren’t offended already, O’Toole hammers it in.

“It’s not the dream of every bus rider to arrive in a bus that was on time, air conditioned and clean, where a seat was available,” the L.A. Times quotes USC civil engineering professor James Moore as saying. “It’s the dream of every bus rider to own a car. And as soon as they can afford one, that’s the first purchase they’ll make.”

Not the dream of most bus riders, but the dream of every single one.  Again, if that doesn’t describe you, you aren’t just invisible or unimportant:  You actually don’t exist.  These are the moments, increasingly common in arguments in our polarized age, when O’Toole reveals that he has no desire to convince anyone who is not already in his cultural camp.

The Nod to Driverless Cars

Finally, there’s the inevitable coda about driverless cars:

Cities that invest in expensive transit infrastructure are ignoring the reality that, long before that infrastructure is worn out, self-driving cars will replace most transit. The short-run issue is that transit agencies that spend billions on rail transit or bus-rapid transit with dedicated lanes are doing a disservice to their customers. The most important thing they should focus on instead is increasing bus revenue miles in corridors where they will do the most good.

I am a big champion of bus investments, but this is the worst possible argument for them, and it’s an especially self-ridiculing argument against rail.  High capacity transit lines — including most the rail lines that O’Toole decries — are the kind of transit that is least threatened by driverless cars, because they succeed in dense cities where there simply isn’t room for everyone to be in a separate car, driverless or not.  (This is also true of many high-ridership bus services, but not for low-ridership bus services.)

Summing Up

What can we say at the end of such a reading?   O’Toole understands transit well enough that he can make substantiated points when he wants to, though he’s also willing to distort statistics with simple tricks like the arbitrary starting year.  His suspicion of rail is overly general but overlaps with some valid questions that have been raised by urban progressives like Matthew Yglesias, especially about slow and unreliable rail projects whose usefulness is no greater than that of buses.  His defense of bus services, when it’s separated from generalized hostility toward transit or blanket dismissal of anything on rails, echoes the view of many minority and low income groups and also of many transit professionals, including me.  Making bus services more useful, after all, is much of what I do as a consultant.

But O’Toole sends constant signals that he does not want to be taken seriously by anyone who lives in, works in, or cares about big, dense cities.  He ascribes to government stupidity anything that smacks of the kind of long-range planning that functional and civilized cities have always required, and he also has little time for the public consultation and consensus-building that governments spend so much time on, and which are a key reason they move so much more slowly than the private sector.

In the end, O’Toole sounds like almost everyone who lives inside of echo chambers today, anywhere on the many political spectra, saying this:  I, and the people choose to I listen to, all share the same tastes and experience and goals, so the fact that we’re right is just obvious!  So, when government disagrees with us it must be stupid and incompetent.  The only other explanation would be that there are actual citizens who disagree with us, because they have a different experience or goals, and that these people are asserting their democratic right to influence the government too.  No, it can’t be!  People who don’t fit my story aren’t “anyone.”  They simply do not exist!

 

Perils of Transit Journalism II: Judge Transit By Its Goals, Not Yours

In the last post I took on the problem of poor data analysis in transit journalism, specifically how easy it is to create totally arbitrary stories out of performance trends.  This post is about another routine mistake in transit journalism, which is to make false assumptions about what transit investments are trying to do.  The most common example is to assume that short-term ridership is the only valid measure of transit’s success.

For this series, I’m taking examples from an example-rich  Los Angeles Times article on the alleged “accelerating” decline of transit ridership in Los Angeles.  The article, by Laura Nelson and Dan Weikel, is provoking a lot of commentary, but it’s not unusual in the assumptions it’s making.

Here’s the lede again:

For almost a decade, transit ridership has declined across Southern California despite enormous and costly efforts by top transportation officials to entice people out of their cars and onto buses and trains.

The Los Angeles County Metropolitan Transportation Authority, the region’s largest carrier, lost more than 10% of its boardings from 2006 to 2015, a decline that appears to be accelerating. Despite a $9-billion investment in new light rail and subway lines, Metro now has fewer boardings than it did three decades ago, when buses were the county’s only transit option.

Long Term Infrastructure Is Not About Short Term Ridership

Here and throughout the article, Nelson and Weikel insistently pair the ridership drop with the $9 billion cost of an infrastructure investment program, giving the reader the impression that they must be connected.

This is like saying that your crops failed because you didn’t have a harvest the day after you planted them.

In this case, the “$9 billion investment” in infrastructure has nothing to do with the short term ridership being discussed here.  The rapid transit program is designed for long-term ridership growth and city-shaping effects.  One of the key things they do, for example, is make denser development viable, which enables more people to live and work where transit is excellent and therefore rely on it more.  Nelson and Weikel quote Metro’s CEO making this point, but doesn’t really explain why long-term investment works.

So how would you assess the value of these lines? You’d look not just at ridership but at what’s happening in real estate development along them.  You’d look at what the trends are in demand for housing and jobs near good transit, and extrapolate to show the benefits — for livability and in terms of long-term ridership potential — of meeting that demand.  And you’d see how similar investments in similar places have paid off in the past.

In a Tweet yesterday, Nelson said:

The ‘it’s too early to evaluate’ response (a favorite of Metro’s) has always struck me as self-inoculating.”

Yes, it can strike me that way too, which is why great transit agencies put a lot of effort into explaining this issue.  But that doesn’t make it wrong.

It takes a while, but great transit investments (and they’re not all great) do pay off when they’re done well.  And when they’re not done well, it’s not ridership that tells you this, but rather contradictions in the plan — like putting stations in places where dense development is illegal or impossible, or building in too many sources of delay while claiming that the line will be fast and reliable.

It’s easy for people to take pot-shots at transit projects by arbitrarily focusing on one outcome.  In a recent Seattle Times panel I was on recently, for example, Brian Mistele of the traffic analysis firm Inrix repeatedly criticized a Seattle area light rail line for not reducing congestion on the adjacent freeway, as though that were its purpose.  Another common example of this mistake is to criticize bus services for low ridership without asking if ridership is even their goal; many bus services exist for non-ridership purposes.

So remember:  If you’re going to imply that something is failing, you have to understand what it’s actually trying to do, and show it’s failing at that. 

Compare Ridership to the Service Offered

A broader point here is that ridership, and especially ridership trends, are meaningless unless they are compared to the service offered to achieve them.  This article gives the appearance of doing that by making a false comparison between short term ridership and long term investments.  This echoes the common fallacy that transit ridership is generated by infrastructure.

In fact, transit ridership comes from operating service.  Infrastructure is mostly a way to make that service more efficient and attractive, but its impact on ridership is indirect, while the impact of service is direct.

So the most important frame of reference for ridership is the quantity of service being operated, not capital dollars being spent.  This is why the article (and transit agency databases in general) should be showing productivity (ridership per unit of service provided.)  This “bang for buck” measure is the only way to tell whether transit is succeeding given how much service is being offered.  

 

Perils of Transit Journalism I: Don’t Let Trendlines Confuse You

When a transit trendline first seems to be going the wrong way, everyone wants an explanation, and most people want a quick one. Almost anyone a journalist asks will have a theory, which is often just a projection of their own tastes.  (“I personally like x in transit, so ridership would go up if there were more x.”)  Transit statistics, sadly, are often not presented in the best way to help journalists and citizens evaluate them — it’s something many folks, including me, are working on.   So it’s tough for journalists to reach any conclusion, and tempting to go for a quick but misleading take.

We need to read the resulting articles with sympathy to the journalist’s challenge but also an application of common sense.  So let’s have a look at Laura Nelson and Dan Weikel’s recent Los Angeles Times article, which discusses a recent moderate drop in transit ridership in greater Los Angeles.

Let me apologize to Nelson and Weikel for calling them out in particular, since my real point is to note how common these mistakes are in transit journalism.  The article contains some very good points about what the agency needs to be doing (better and faster buses) which are well-supported by the data and which I’ve discussed at length here.

Still, whole frame of the article is misleading, in two main ways:

  • the use of data, which I’ll discuss in this post.
  • the comparison of data to investments, which I’ll discuss in the next

Ridership Data is Noisy, so One or Two Data Points are Not a Trend

The chart in the article shows that ridership has been falling for one year, based on just one data point (Later in a Tweet, Nelson told me she had two data points, with ridership down in both calendar 2014 and ’15, but that’s not in the article or the chart.)

la-me-g-ridership-slump-20160126-1

Based on these one or two points, the authors propose a vast and ominous trend:

The Los Angeles County Metropolitan Transportation Authority, the region’s largest carrier, lost more than 10% of its boardings from 2006 to 2015, a decline that appears to be accelerating. Despite a $9-billion investment in new light rail and subway lines, Metro now has fewer boardings than it did three decades ago, when buses were the county’s only transit option.

Accelerating? You need many data points to support this claim, because you are saying not just which way the line is going but also how it’s curving.  What the published chart shows is that:

  • There’s a larger interesting story about the broad fall in ridership across the 90s and dramatic recovery across the 00s.
  • Ridership has been generally flat since 2006, going up and down in about a 10% band, with no sign of strong movement in any direction.

Let’s acknowledge what a hard problem this is for journalists.  Something seems to be happening in the transit data.  People are asking about it.  You work on a short turnaround.  It’s very hard to take on the truth, which is that ridership data is very noisy, so it takes a long time to see a trend.

This, by the way, is why I’ve done so little commentary on trends since the August 2015 implementation of Houston’s new bus network, whose original design process I led.  Ridership was down the first month, so people wrote omnious articles.  Then it soared the next month, so people wrote triumphalist articles.  Now it looks like it may be down a little (post on this soon).  Ridership data is just very volatile, so a trend has to be going for a while before you can call it.

Watch for the “Arbitrary Starting Year” Trick

When a journalist says some grand thing has been happening since year y, you should immediately ask: “why year y in particular?”  Again, here’s how the article opens:

For almost a decade, transit ridership has declined across Southern California despite enormous and costly efforts by top transportation officials to entice people out of their cars and onto buses and trains.

Why “almost a decade”?  Why not just a decade?  Because if you compared 2015 to 2005 instead of 2006, ridership wouldn’t be down, and the authors wouldn’t have a story.

Sure, ridership is down 10% since 2006. But it’s up since 2011 and way up since 2004.  Want to talk about the grand sweep of history?  Nelson says that ridership is lower than it was 30 years ago, which sounds terrible, but it’s higher than it was 25 years ago!  Thirty years ago, by the way, was fiscal year 1984-85, the year of the Olympics, so of course ridership was unusually high.  [Update: Henry Fung, channeled by the excellent Ethan Elkind, has shown that it was fare cuts, not the Olympics, that made 1984-85 such a banner year.]

With a trendline like the one in the chart, you can say anything you want by comparing some past year to the present.  Your conclusion is about the year you chose.

This “arbitrary starting year” trick is a very common in misleading journalism.   Be suspicious whenever you see a single past year is cited as a point of comparison.

In Part 2, I’ll talk about the problem of comparing transit outcomes to transit investments.
