dangerous word watch: integrated, integration

Whenever someone in a planning or transport field tells you they work on "integration" or "integrated x", ask them:  "Integration of what with what, exactly?"

Integrated and integration carry a root meaning of things that are normally separate being combined or dealt with together.  Thus we speak of integrating transport and land use, integrating two adjacent transit networks, or integrating functions within an organization (as in the term vertical integration).  

Because we've all been taught to fear silos, which are areas of activity dealt with in isolation, we are supposed to love the word integrated, which implies somehow that this problem has been overcome.  

But communities have to choose between different integrations. 

For example, recently, I was dealing with a city that controls its own transit system, and that was wondering if its service should be integrated with its suburban transit agencies.  This would have required giving up city control of the agency to a regional authority.

But this idea would also disintegrate.  Specifically, it would prevent the integration of the city's transit thinking with the city's thinking about traffic, parking, and land use.  Whereas a city government can plan all these interdependent things together, they often find it easier to deliver great transit outcomes than a city that must rely on a regional transit agency can.  It is too easy, in a city's politics, for a regional transit agency to be seen as Other, not part of the city in a bureaucratic sense and thus prone to neglect or exclusion when the city sets its own priorities.  After all, we all prefer to think about things we control rather than things we don't.

I'm not expressing an abstract view about whether city control or regional agencies is the right way to organize transit.  The answer is different in different places.

But I am warning about the word integrated, when used without clear reference to which specific silo walls are being broken down.  If you're not clear about that, and you don't demand clarity from others who use the word, integration may not give you the specific integration that matters most to you.  

Even integration can be a silo.

 

auckland postcard (speaking here thursday!)

DSCF5578I'm back in New Zealand for the next two weeks, which is always a pleasure.  I'll be teaching three sessions of my course (all booked out, alas, but there can always be more) and doing a series of private briefings.  

But I'll also be doing a lunchtime talk in downtown Auckland this Friday, as part of the Auckland Conversations series.  My topic is How will an integrated public transport network create a city for people?  RSVP here!

The "integrated public transport network" in question is more or less this one.  My biggest project for 2012 was a complete redesign of Auckland's confusing tangle of infrequent bus routes, working with Stuart Donovan and my other excellent New Zealand colleagues at MRCagney.  This project is now being rolled out, starting with the southern part of Auckland next year.  

Auckland is a very exciting city for public transit right now.  An antiquated and infrequent commuter rail system is being converted to useful rapid transit, first by running more trains but more durably through an electrification project.  The bus redesign will bring useful all-day frequent service to a huge share of the population, as these striking maps demonstrate.  

Finally, if you're not in Auckland, my most important post from here is this one, about expanding our notions of why you might paint a bus.  

quote of the week: ursula le guin on technical writing

In poetry, by and large, one syllable out of every two or three has a beat on it: Tum ta Tum ta ta Tum Tum ta, and so on. . . .

In narrative prose, that ratio goes down to one beat in two to four: ta Tum tatty Tum ta Tum tatatty, and so on. . . .

In discursive and technical writing the ratio of unstressed syllables goes higher; textbook prose tends to hobble along clogged by a superfluity of egregiously unnecessary and understressed polysyllables.

meta: comments now require sign-in

This blog's comments have always been hugely valuable, and some magnificent conversations have occurred in comment strings.  I hate having to restrict them in any way (apart from the comment policy).  

Sadly, this blog is now experiencing a comment-spam attack, and the "captcha" tool for verifying commenters appears to be useless.  Our host, TypePad, can offer little assistance, and now and then makes things worse.

So two changes:

  • Comments have been closed on some older posts that were attracting heavy spam. 
  • As of now you will have to register via any of a range of online identities, including Twitter, Facebook, and so on to comment.

If that doesn't work, we will probably begin (with regret) closing comments on all but the most recent posts.

Please keep commenting!  Your comments have always been at least half the value of this blog.

should transit maps be geographical or abstract?

In some agencies, it goes without saying that transit maps should be geographically accurate.  Many agencies follow San Francisco Muni in superimposing transit lines on a detailed map of the city:

Sf frag

But research out of MIT suggests that we really need to see network structure, and that requires a degree of abstraction:

By putting alternate versions of the New York and Boston subway maps through the computer model, the researchers showed that abstract versions of the maps (as opposed to geographically accurate versions) were more likely to be easily understood in a single, passing glance. 

Here's their example:
Dish_subwaymaps

Geographical accuracy obscures network structure.  Purely geographic maps show where service is but not how it works.  

This is why a number of best practice agencies publish both kinds of maps, sometimes even presenting them side by side.  The geographic map helps you locate yourself and points of interest in the city, but you need the structure map to understand how the system works.

All this is even more urgently true for bus network maps, where complexity can be crushing to the user.  When we streamline maps to highlight key distinctions of usefulness such as frequency, we often have to compromise on geographic detail.  Obviously the best maps fuse elements of the two, but you can always find the tradeoff in action.  The new Washington DC transit maps, for example, highlight frequency (and show all operators' services together) but there's a limit to the number of points of interst you can highlight when keeping the structure clear:

postcard: al ain

A couple of weeks ago, I had the honor of joining a consulting team working on Bus Rapid Transit in Al Ain, United Arab Emirates.  Al Ain, pop. around 500k, is straight south of Dubai, inland, and it could not be more different.  While Dubai is a performance for the world, Al Ain is calm, satisfied and a bit inscrutable.  Expat workers abound, including plenty of professionals hired from the West, but this feels like a city for Emiratis.

IMG_1210
Built around a series of oases, Al Ain has been a crossroads and watering place for millennia.  Like most such places, it's a bit of a chokepoint, defined by the Omani border and the massif of Jebel Hafeet rising to the south.

What's here for a transit  blog?  This:

IMG_1273

"Grow a vision with public transport," with the obligatory child photo.  (Another shows an Emirati man in agal and ghutra gazing thoughtfully into the distance.)  Al Ain recently started up a bus system, and has a nice downtown station under construction.  As you'd expect in the Emirates, it's mostly used by low-income guest workers from surrounding countries.  Emiratis, who are a minority of the workforce, are mostly relatively wealthy and generally drive.  

But why, if that's today's reality, would a public transit system be unveiled with such modern and air-conditioned buses?  And why did they undertake this kind of marketing and imagery, designed to get Emiratis thinking about public transport and why it might be important for the city's and country's future?

Often, in the US, I encounter the attitude that buses are just for the poor and that therefore there's no point in spending more than the minimum on them.   Plenty of US cities have bus systems whose service and infrastructure still convey that attitude.  In these situations I'm always pointing out that transit dependence, like income, is a spectrum, that there are people everywhere along the spectrum, and that transit can therefore grow incrementally in relevance in response to modest, incremental investments.  Even poor people make choices, and those choices have consequen  This is, among other things, a reason to care about the quality of bus services, rather than just longing for trains.

That line should be a harder sell in the Emirates, a wealthy country where (a) decision-making is concentrated in an elite, (b) the middle class is far smaller and newer than in the US, and (c) the underclass consists of foreign "guest workers" who have little political influence.   But the Al Ain bus system, and its vision-heavy marketing and investment in look and feel, suggests they may grasp the idea better than many Americans do.   They are envisioning a future when a more diverse range of people will be motivated to use transit, as the car becomes less attractive or affordable for a host of converging reasons. 

 

toronto: communicating transit’s hard truths to the public

The Ontario Transit Panel, convened by the province's Premier in September, released its first 'discussion paper' this week entitled "Hard Truths About Transit in the Toronto Region". This group exists to advise the Province on whether or not to support the agenda of the regional transit agency, Metrolinx.

While specific points will be familiar to readers of this blog, the document is notable as a good example of how to educate local people in a local context. This paper asks people to consider the real consequences of choices based on the facts of how transit works, rather than reproducing stereotypes or promising impossible outcomes. As the report says:

These are hard truths, but until we accept them, we will not be able to have a mature discussion. Decisions will not be based on reason and evidence, but will be one-off decisions aimed at short term political gain.

are smartphones changing the geography of our cities?

The increasing prevalence of mobile communications technologies has important consequences for urban transportation. The new ability to carry your social life around with you, enabling instant connections regardless of physical location, has the potential to reconfigure how we think about time and mobility, and in turn how we build environments to suit our travel behavior.   For example, it appears to be impossible to use smartphones safely while driving, so smartphone users have a motive to seek an alternative mode so that they can make use of their travel time.

 Ben Schulman has an interesting take on this in his paper, The Car as Smartphone: Effects on the Built Environment and Sociality, which you can download below. He places the smartphone in a continuity of change in human communications technology, and traces how those technologies have helped to shape our cities. 

The built environment then is a reflection of the predominant communication devices being used at given points in time that shape sociality. In other words, we develop an infrastructure necessary to accommodate the needs of our preferred communication tools.

This idea is a larger envelope around the familiar idea that all cities are built around the transportation technologies of the time.  Transportation, after all, is one kind of communication tool.

There is a lot of to digest here, but it is well worth a read in order to situate these trends within an academic urbanist frame of reference. My take is that the role of communication is hugely important, but must be understood as an aspect of a broader web of economic and social relationships which together work to produce the space of the city.

time for an urbanist “tea party”? the citylab conversations

The "tea party" US House members who currently dominate the news are unlikely allies of urbanists.  But on one core idea, a band of urbanist thinkers are starting to echo a key idea of the radical right:   Big and active national government may not be the answer.

Images-5Last week, I was honored to be invited to Citylab, a two-day gathering in New York City sponsored by the Aspen Institutethe Atlantic magazine, and Bloomberg Philanthropies.  The event featured mayors and civic policy leaders from both North America and overseas as well as leading academics, journalists, and consultants.  

I expected the thrilling mix of new ideas, compelling stories, and quirky characters, but I got one thing I didn't expect:  A full-throated demand, from several surprising voices, for an urbanist revolt against the power of national governments.

Al Gore said it with his trademark fusion of bluntness and erudition: "The nation-state," he said, "is becoming disintermediated."  If you're not an academic at heart, that means: "National governments are becoming irrelevant to urban policy, and hence to the economy of an urban century."  

On cue, the New York Times published an op-ed on "The End of the Nation-State," about how cities are leaving nations behind.  Citylab also featured a terrific interview with political scientist Benjamin Barber, whose new book If Mayors Ruled the World argues for the irrelevance of nation-states in a world where cities are the real levers of economic power.  (According to Barber, the full title of his book should have been:  If Mayors Ruled the World: Why They Should and How They Already Do.)  When I spoke with Barber later, looking for nuance, he was full-throated in ridiculing the US Federal role in urbanism.   On this view, all the well-intentioned money that the Federal government doles out for urban goodies should be spent by cities as they see fit, or perhaps (gasp) never sent to Washington at all. 

Follow this logic and you might arrive at a radical urban Federalism, perhaps even one that could meet tea-party demands to "Abolish the IRS!"   Pay taxes to your city or state, and let them send a bit of it on to central government to do the few things that only a central government can do.  Push power downward to the scale where problems can be solved. 

You might even separate urban from rural governance in a way that enables both to thrive, each at its proper scale, replacing the eternal struggle between these necessary opposites that makes today's political discourse so inane.  The "size of government" debate is just a pointless and eternal struggle between urban and rural experience, both of which are right.  Living in cities means relying on government for many things that the rural resident provides for herself, so of course the attitude toward government is different.   But what's really logically different is the role of local government. Both urban and rural experience provide good reason to be suspicious of big-yet-distant national government, which can be as unresponsive to big-city mayors as it is to a Wyoming county official who just needs to get a bridge fixed.

At most of the urbanist and transportation conferences that I attend, though, any shrinking the national government role is met with horror.  And that's understandable.

In the US, the prevailing local response to declining federal spending is outrage and redoubled advocacy.  In Australia or Canada, two countries I work in extensively, working urbanists and infrastructure advocates seem to agree that of course there must be a bigger central government role in everything, with the US often cited as the model.  In the US itself, it's easy to see the current cuts in Federal spending as a disaster for urbanism and infrastructure.  It is, but it could also be something else: an invitation to governments that are closer to the people to have their own conversations that lead to local consensus about funding and solutions.

If mayors do end up ruling the world, it will be because the city, unlike the state or nation, is where citizenship is mostly deeply felt.   A nation's problems are abstract; if they show up in your life you're more likely to think of them as your community's or city's problems.  And that, in short, is why the city may be best positioned to actually build consensus around solving problems, including consensus about raising and spending money.  

And yet …

Before urbanists join the tea partiers in trying to shrink the national government, they have to grapple with the problem of inequality.  As sites of concentrated opportunity, cities are attracting the poor as well as the rich, and are thus becoming the place where inequality is most painfully evident.  But no mayor can be expected to solve a problem that exists on such a scale.

In small-c conservative terms, of course, the problem is not income inequality but rather the declining credibility of a "ladder of opportunity" that convinces everyone that reasonable effort will improve their circumstances.  One reason to care about transit, walking, and cycling — for many points on the income spectrum — is that transportation can form such a formidable barrier to opportunity.

All through Citylab, hands were wrung about inequality and the need to Do Something about it, against the backdrop of a New York City mayoral election that is mostly about this issue.  A rent control debate, featuring New York City Planning Director Amanda Burden and economist Paul Romer, found no middle ground on the question of whether city policy can usefully intervene to help low income people.  Income inequality appeared to be one issue where cities can do little by themselves.

When I asked sociologist Richard Florida about this in the North American context, he pointed me to an article proposing that the US create a Department of Cities.  He has good ideas about how to keep this from being just another bureaucracy, but if income inequality is the big issue that only national policy can address, it's not clear that it should be tagged as an urban issue at all.  Cities are not where the problems are.  Cities are just where people see their society's problems most intensely in daily life, because they get out of their cars.  

The great city in the wealthy parts of the world cannot just be an enclave of success.  It will deserve the self-government that the mayors seek only if it relentlessly inspires, supports, and gives back to its suburban and rural hinterland, creating its own "ladder of opportunity" for access to the riches of urban life.  Only a few people can afford Manhattan or San Francsico, so those cities' money and expertise must focus not just on themselves but on making life in more affordable places incrementally more humane.  Turning Newark into Manhattan would just make it unaffordable, so some of the urgency must lie in less photogenic intervention that works for each place's price-point.  It lies in providing safe places to walk and cycle, and  a safe way to cross the street at every bus stop, even in landscapes of drive-through everything that will be what many people can afford, and what some prefer.  

That's why I'm happy to be working not just in San Francisco but also in Houston, where affordability is a leading selling point.   It's why I'm suspicious of transit planning that defines an elite "choice rider" as the only important customer, including much of the transit-aestheticism that comes out of urbanist academia.  Where are the prestigious awards for the best affordable, scalable, but nonsexy intervention that made low-income inner-ring suburbia more safe and functional?  How do we build not just the shining city behind a moat (San Francisco, Manhattan, Singapore) but a chain of humane and functional places, at every price-point, that combine safety, civility and opportunity?

Where is the money in that?    If mayors ruled the world, I hope that would be obvious.  So let's hope they already do.

frequent network maps: the challenge of one-way pairs

One-way splits — where the two directions of travel are on different streets — are often the scourge of transit: on the map, for example, they appear to cover more area than two way service, but actually serve less.  And they certainly make transit maps confusing:

Indxmaps2

Still, they're frequently mandated by one-way traffic couplets.  Those, in turn, are usually mandated by the goal of flushing traffic through a city, though there are cases, notably Portland, where one-way couplets are perfect for creating an intimate and walkable downtown.

Transit agencies may not be able to avoid one-way couplets, but they can control how they describe them and think about them.  WMATA (and its map designer, CHK America, have made a major step in their new network map.  We covered the development of this mpa previously. Here's what it looks like today:

Red represents the most frequent bus lines, blue the infrequent ones, and black the DC Metro system. Other colors are used to depict services of other transit agencies. This basic, clear symbolization quickly communicates the relative importance and usefulness of each type of service.

Marc Szarkowski, who contributed his own frequent network map of Baltimore to the blog last week, asks: how do we show a single route that runs as a two-way couplet on separate streets, without introducing too much clutter or confusion? 

Marc writes:

I think they can work if presented effectively, but overall I often find them confusing, especially if I'm taking an unfamiliar route to an unfamiliar area (all the more you have to remember, particularly if you take multiple such routes). For example, whenever I ride a bus to an unfamiliar area, I tend to assume that the stop I get off at in one direction is just as good for boarding in the other direction. It's frustrating to return to the stop just to discover that you have to walk a block over (or sometimes more: see the 10 in West Baltimore!) to catch the same route in the other direction. 


Screen Shot 2013-09-30 at 10.29.07


WMATA's map uses one line to show both branches of route, and labels either side with the couplet streets. This effectively reduces the amount of clutter on the map, but also excludes which direction the bus travels on each street. This information is less crucial in the case of the B2 shown left, where no other routes travel on the same pair of streets, but where multiple routes use the same streets, in different patters towards different destinations, combining paired one-way streets can become very confusing. Marc's map does not employ this method of simplification for the same reason: 

In Baltimore's case multiple overlapping routes were sometimes offset across a series of three or more one-way streets; i.e. Route 1 up on street A and down on B, Route 2 down on B and up on C, Route 3 up on C and down on D, and so on

Ultimately, desiging this type of a map is about balancing information density and comprehensibility. The user needs to know that line B2 runs on both 14th and 15th streets, but for a map at citywide scale, it may be more important to communicate that B2 is a frequent line serving a long, straight corridor on the eastern side of the city. The map already distorts direction and the exact shape of the streets in favor of a simpler visual effect. WMATA's map uses the same approach to one-way street pairs, downplaying accuracy in favor of ease of use.
