book review: grescoe’s straphanger

Taras Grescoe. Straphanger: Saving Our Cities and Ourselves from the Automobile. Macmillan, 2012.

Straphanger cover

When the publisher of Taras Grescoe’s Straphanger asked me to review the book, I felt the usual apprehension.  Shelves are full of books that discuss transit from a journalist’s perspective.  They often get crucial things wrong, as do many journalists’ articles on the topic.  I wondered I was going to endure another four hours of watching readers being innocently misled on issues that matter.

Grescoe does a little of that, but he also shows why spectacular writing compensates for many problems of detail.  Straphanger is a tour de force of compelling journalism and “travel writing” – friendly, entertaining, funny, pointed, and (almost always) compelling.  Like any good explainer, he announces his prejudice at once:

I admit it: I ride the bus.  What’s more, I frequently find myself on subways, streetcars, light rail, metros and high-speed trains.  Though I have a driver’s license, I’ve never owned an automobile, and apart from the occasional car rental, I’ve reached my mid forties by relying on bicycles, my feet, and public transportation for my day-to-day travel … I am a straphanger, and I intend to remain one as long as my legs will carry me to the corner bus stop.

Grescoe and I have almost all of this in common, but I felt a pang of regret at this posture.  To the mainstream, car-dependent people who most need this book’s message, Grescoe has just announced that he’s a space alien with three arms and a penchant for eating rocks.  But there’s a positive side: once you decide you’re not in danger, eccentric tourguides can be fun.  Perhaps I have a poor dataset from living in “officially weird” Portland, and before that in San Francisco, but in a culture that seems increasingly welcoming of eccentricity and difference, there may be an audience for Grescoe among the motoring set.

Because this is what Grescoe is at heart:  A great tourguide, in this case a travel writer, showing you around some fascinating cities, exploring intriguing transit systems, and introducing us to vivid and engaging characters, all while having fun and sometimes dangerous adventures.  These last are important; Grescoe has had enough traumatic and confronting experiences that he can describe straphanging as a form of endorphin-rich adventure analogous to mountain climbing or skydiving.  I look forward to the movie.

Statistics are cited lightly but to great (and usually accurate) effect.  Effective and quotable jabs are everywhere: 

“The personal automobile has, dramatically and enduringly, broadened our horizons.  In the process, however, it has completely paved them over.

Grescoe has a great eye for characters, too.  Who can fail to be charmed, for example, by this portrait of a character I hadn’t known:  Bogotà mayor Antanas Mockus, alter-ego of his successor, the aggressive and practical Enrique Peñalosa:

Working with a tiny budget and no support from district councillors, Mockus focused on … undermining cycles of violence through jester-like interventions in daily life.  He dismissed the notoriously corrupt traffic police and hired four hundred mimes to shame drivers into stopping at crosswalks.  …  Taxis drivers were encouraged to become “Gentlemen of the Crosswalks,” and every new traffic fatality was marked with a black star prominently painted on the pavement.  To discourage road rage and honking, he distributed World Cup-style penalty cards to pedestrians and motorists, a red thumb’s down to signify disapproval, a green thumbs up to express thanks for a kind act … Seeing tangible evidence of municipal progress, citizens once again began to pay their property taxes … and the once-bankrupt city’s finances began to recover.

What’s wrong with this book?  Well, if it’s travel writing, nothing; travel writing is about the adventure, and while you learn things from it, you expect to learn subjective, unquantifiable things that may be inseparable from the character of your guide.  Journalism, on the other hand, has to get its facts right, or at least state its biases.  Grescoe gets a pass on his largest biases, mostly because he’s entirely aware of them and happy to point them out.

But there are a few mistakes.  Like many commentators, Grescoe throws around meaningless or misleading data about urban densities.  Here’s a typical slip:

Thanks largely to the RER, the metropolitan area of Paris, with over 10.2 million residents, takes up no more space on the Earth’s surface than Jacksonville, Florida, a freeway-formed city with fewer than 800,000 residents.

This doesn’t seem to check out, unless some subtle and uncited definition of metro area is being used.  (Wikipedia tells me that the City of Jacksonville is 882 sq mi in area while the Paris with 10.3 million residents is 1098 sq mi.)  But even if it did, this is the classic “city limits problem.”  Jacksonville is a consolidated city-county whose “city limits” encompass vast rural area outside the city, whereas “metro Paris” is by definition a contiguous area that is entirely urbanized.  An accurate comparison with metro Paris would look only at the built-up area of Jacksonville, which is tiny compared to Paris.   The point is that any talk about metro areas or cities is prone to so many different definitions, including some really unhelpful ones, that it’s wrong to cite any urban density without footnoting to clarify exactly what you mean, and how it’s measured. Grescoe is far from alone in sliding into these quicksands.

As with many journalists, Grescoe’s sense of what would be a good transit network is strongly governed by his emotional response to transit vehicles and technologies.  Grescoe is very enamored with rapid transit or “metro” service to the point that he sometimes misses how technologies work together for an optimal and liberating network. 

He claims, for example, that there should be circular metro lines around Los Angeles, Chicago, and Toronto.  In fact, circular or “orbital” services (regardless of technology) rely not just on network effects but also on being radial services into major secondary centers.  This is why the Chicago Circle Line made no sense: Chicago is so massively single-centered that there are few major secondary centres sufficient to anchor a metro line until you get way out into the suburbs, at which point concentrations of jobs are laid out in such transit-unfriendly ways that no one line could serve them anyway. Chicago is going the right direction by improving the speed and usefulness of its urban grid pattern of service – a mathematically ideal network form that fits well with the shape of the city.  Toronto has similar geography and issues.  As for Los Angeles, this is a place with so many “centers” that the concepts of radial vs orbital service are meaningless.  Especially here, where travel is going so many directions and downtown’s role is so small, the strong grid, not the circle, is the key to great transit. 

Grescoe is clear enough about his strongest bias:

“I don’t like buses. … Actually, I hate them.”

Despite his opening statement that “I ride the bus,” Grescoe repeatedly associates buses with losers, and with unpleasant experiences.  In correspondence with me, he wrote:  “The anti-bus bias you perceive was a concession to North American readers whose experience of buses tends to be negative.”  Again, this is understandable as travel writing, but it’s tricky as journalism and very tricky if the purpose is advocacy.  When you presume a bias on the part of your reader, with the intent of later countering it, you can’t really control whether you’ve dislodged the bias or reinforced it.  I felt the bias being reinforced; other readers may have different responses.

Again, the problem with anti-bus bias is not that I don’t share it.  The problem is that if you set transit technologies in competition with one another, the effect is to undermine the notion that technologies should work together as part of a complete network.  If you want a network that will give you access to all the riches of your city, buses are almost certain to be part of it – even if, as in inner Paris, you have the densest subway system in the world.  Hating buses – if that becomes your primary focus — means hating complete networks. 

When it comes to Bus Rapid Transit, Grescoe accepts the common North American assumption that the place to see BRT is Bogotà or Curitíba.  So he comes back from Bogotà with the near-universal reaction of North American junketers there:  The massive structuring BRT is really impressive in the numbers it carries, but hey, this is the developing world. Not only is car ownership low but it’s more authoritarian in its politics, giving mayors the power to effect massive transformation fast without much consultation.  What’s more, these massive busways are effective but really unpleasant as urban design – not something I’d want in my city.  Respecting the effectiveness and utility of the Bogotà busways, Grescoe does endorse Bus Rapid Transit in secondary corridors, but he has not seen busways done completely for a developed-world audience.

North Americans who want to experience successful Bus Rapid Transit in a developed-world context should skip South America and visit Brisbane, Australia, where a wealthy modern city moves, in part, on a complete network of beautifully designed, landscaped, and highly functional busways that flow into an underground segment right through the heart of downtown, and that are designed to provide an extremely frequent rapid-transit experience.  There are some European pieces of good busway, such as Amsterdam’s Zuidtangent.  But you have to go to Brisbane to see an uncompromised developed-world busway network, one that provides reliable operations end to end.

While Straphanger’s flirtation with anti-bus stereotypes was troubling to me, there’s a limit to how much Grescoe can be criticized for this.  This is journalism of its time, and the bus=loser stereotype is still of our time in some cities.  It’s up to each of us to decide whether to seek experiences that confirm our stereotypes or those that might contradict them, but nobody can challenge all of their stereotypes at once.   Grescoe does eagerly challenge many other destructive attitudes throughout the book, and the brilliance of a book lies in the way it brings delight and confidence to the experience of both using and advocating transit and great urbanism. I heartily recommend this fun, enlightening, and inspiring read.

los angeles cuts bus line that was useful parable

Almost a year ago, I told the story of Los Angeles line 305, a diagonal line that ran every 40 minutes zigzagging across the city's high frequency grid, between Watts and Beverly Hills.  The line was so infrequent, and the surrounding grid service so frequent, that if you just missed the 305 it was faster to take the frequent grid routes and transfer than to wait for the next 305. 

The 305 comes up often in my presentations because it's such a useful example of symbolic transit.  The purpose of the line was not to be useful to very many people, but rather to announce, as a matter of symbolism, that "we run from Watts to Beverly Hills"!  That's certainly how Jennifer Medina of the New York times described it, when it was first proposed to be cut in 2011.  The Times's graphic:

 

4bus-map-popup

The NYT headline of the time even claimed that cutting this line would "make a long bus commute longer," which was factually untrue if you count waiting time as part of travel time.

Well, a year later, LA Metro is finally cutting the 305.  Very few people will experience any loss of travel time as a result, but the system will be simpler, more frequent, and ultimately, more liberating for anyone who wants to get where they're going.  Of course, like such worthily deleted lines as San Francisco's 26-Valencia, the 305 will still be useful as a parable!

 

richard florida’s supersized-airport theory

Bkk airport
Richard Florida has discovered that as cities get bigger, airport traffic goes up even faster than population.  Here's his interpretation:

As with other features of metropolitan life, such as productivity or invention, airport passenger traffic increases disproportionately with population size. This is yet another manifestation of the overall acceleration of social and economic life that occurs in urban population centers—a phenomenon that has been dubbed “superlinear scaling.”

OK, but how much of this is what transport planners call the network effect?  Just as transit planners try to locate connection points at already-active locations, airlines are motivated to locate their hubs in major cities, so that the city and the hub support each other in creating the largest possible market for flights in and out.

For example, ask: what's the biggest US metro area that is NOT an airline hub?  Using this table  (and setting aside greater Riverside because its airport is run by Los Angeles) I get all the way down to San Diego, the 17th largest, before I encounter one where hub effects have little role in the airport's function.  So it doesn't surprise me that the scaling of big city airports is "superlinear" (a fancy word for "curving upward") compared to population, for the same reason that boardings at major transfer points in a transit network are superlinear compared to their immediate surroundings.

I could interpret this as a nice example of the very common tendency of people with social science training to overread demographics and economic indicators, while underreading the effects of network structure and how it determines the actual utility of transport service.  This issue comes up in transit all the time. 

But another interpretation, more to Mr. Florida's liking, would be that the connection in a transport network is not really all that different from the social connections that occur in urban life.  Florida is famous for documenting how all these connections rise in non-linear ways as there are more people around to connect, thus leading to hotspots of creativity and innovation. 

When I suggest that transit agencies use the word connection, instead of the dreary word transfer, it is to invoke exactly this association.  A transport connection isn't just an analogy with the social, cultural, and intellectual connections that drive innovation.  In its multiplying power it's almost the same thing.

a great new resource on european buses and bus rapid transit

In case you've missed the headlines, Europe's economy is even more shaky than that of the US, with the consequences of the global crisis overlaid with the crisis of the Euro.  So as in the US, it's time to do more with less. But they're doing a lot more with less, as you can see by browsing this great online resource, www.bhls.eu.

  Bus_at_stop_N_Riverside_Gothenburg-2

26_-_Nantes_-_bus_way_vue_aerienne_BDefBHLS stands for "Bus at a High Level of Service" and it refers not just to Bus Rapid Transit but to a range of other high-frequency, branded bus products.  The site features case studies from all over Europe, and provides numerous PDF downloads where you can read about individual cases in more detail — not just sexy photos but (Gotheburg above, Nantes at right) but also an explanation of the decision process that led to choosing a bus project over rail.

I'm trying to buy a house and pack up my office today, and will be at the Canadian Urban Transit Association conference in Victoria the next few days, so posting may be slow.  Fortunately, there's enough at www.bhls.eu to entertain anyone who cares about urban transit for days.

 

 

 

fort lauderdale: yet another triumph for multi-destinational networks

If your city is producing lousy outcomes with its bus services, are you sure it's because of the buses, or the drivers, or the sidewalks, or the degree of "transit oriented development", or that they're not streetcars?  Maybe it's because the network structure is obsolete.  A study team led by Gregory Thompson of Florida State looked at the success of Broward County Transit, which serves greater Fort Lauderdale.  Apart from a few special enclaves, Fort Lauderdale is unlikely to be high on anyone's list of urbanist paradises.  It has plenty of gridlock, plenty of pedestrian-hostile environments, and the usual abundance of oversized roads that seem only to generate more congestion.

Broward sidewalk campaignYet the hard-working if unappreciated Broward County Transit system is producing excellent outcomes through multidestinational design.  Instead of running a radial system into a single downtown, they decentralized to serve many destinations, through a network of routes making easy connections with one another. Eric Jaffe tells the story today in Atlantic Cities.

The whole case for this kind of design is in my book Human Transit, esp Chapter 12 and 13, but Thompson has been making it for years.  I'm impressed at how well it's working in not-especially-transit-friendly Florida metros.  Tallahassee took the plunge last year.

Obviously this is an issue close to my heart.  I came to consciousness as a transit planner during the decentralization of Portland's network in 1979-82, which created local pulse networks in each suburban area and culminated in the high-frequency grid that today covers most of the city.  Almost every network design I've ever done has helped to improve the multi-destinational utility of transit networks of all sizes.  Huge amounts of resistance have to be overcome.  But if they're designed well, they work. 

Finally, kudos to the folks at Atlantic Cities for coming back to this issue with one great story after another.  I'm not sure I've ever seen a major media outlet build up this degree of internal understanding about the fundamentals of transit network design — a topic that's easily forgotten while obsessing about how cool technologies are.   Is any other American media outlet dealing with network planning issues so clearly?  Certainly not the New York Times, which publishes one story after another in which well-meaning platitudes about social needs are proposed as ways to change the facts of geometry.

paris: “the bus stop of the future”

Now that Paris has bus lanes on almost every boulevard, we can expect their transit agencies to continue investing and innovating around their frequent and popular bus services.  Today we get "the bus stop of the future," where designer Marc Aurel has packed in every convenience that will fit in the space, plus a few more.

Yes, it's still a bus shelter, but the idea is to make it both more useful and more of a social space.  People may come here for a range of things other than catching the bus, so that social interaction and the life of the street intermix with waiting to produce a more vibrant, interesting, and safe environment.  It's the same principle by which transferring passengers can help activate civic squaresFrom Bati-journal (my rough translation):

This experimental station at boulevard Diderot is not just a place to wait for a bus. Covering an area of ​​80 m2, it was designed as a multi-purpose public space … .  Here you can buy a bus ticket, get information about the neighborhood, have a coffee, borrow a book, play music, recharge a phone, buy a meal to take away, rent an electric bike, stay warm while eating a sandwich, or set up a bag on a shelf to do your makeup.  Variable light adjusts for day and night conditions. This project will also be the first urban test of materials and technological innovations … such as ceramic furniture invented by Marc Aurel, and a sound design integrated into the fabric of furniture …

I'm disappointed they didn't include an art gallery with some durable lendings from the Louvre, on the model of Louvre-Rivoli station

But seriously:  This is what a major bus stop or station might look like if you really, really valued buses, and also value the principle that uses of the street should be intermixed so that they contribute activation, interest, and safety to one another. 

vancouver publishes frequent network map

The Wayfinding team at Vancouver's TransLink has finally unveiled their new network map, with Frequent Network designations.  In this case … orange:

Vanc freq netk slice

Download the whole thing here: regional transit map

The term "FTN" (Frequent Transit Network) also appears on the map here and there.  This term has already been used for several years in TransLink policymaking.  In fact, four years ago in Transport 2040 TransLink committed to this goal:

The majority of jobs and housing in the region are located along the Frequent Transit Network (frequent, reliable services on designated corridors throughout the day, every day).

Now, finally, the public can see it too!  Disclosure: I had a review-and-comment role in a few stages of this process, but it's definitely TransLink's work, led by their excellent Wayfinding team.

shock-shifting to transit, but not back

When some disruption or unusual event causes people to shift from driving to transit, many never shift back.  Ezra Klein  Brad Plumer reviews the evidence in the Washington Post. 

He's talking mostly about shifts caused by gas price shocks, but something similar happens in response to major disruptive events.  For example, the 2010 Olympic Winter Games in Vancouver caused a major burst in ridership — obviously a mix of Olympic visitors and residents who were trying to avoid Olympic traffic.  But ridership never dropped to pre-games levels, and in fact, 2011 ridership was higher than 2010, despite the huge influx of Olympic visitors in 2010.

Klein goes on to lament that the very fuel price volatility that affects transit ridership also affects transit's funding, since federal funding is based on fuel taxes so they drop when fuel use drops.  Unfortunately, US local operating funding (which is the real crux of the matter) is even more volatile, depending typically on payroll or sales taxes.  Loss of a job equals a drop in payroll taxes, and causes drops in spending shortly afterward.  

I wonder if we'll eventually create something like a property tax surcharge that captures some of the benefits of transit to a location — possibly based on some future, vastly more objective Transit Score or index of transit access.  Road funding could work the same way, but tending to fall more on the properties that benefit least from transit, since higher road use correlates to lower transit use.  Property taxes (inevitably passed through to renters) are the least volatile funding source around, and if you want your transit agency to work on real service improvement, instead of endless cycles of cuts, adds, and cuts, we'll have to find our way to a more stable funding solution.
