Three Eye-Opening Papers On How We Build Transit

The other day I discussed how modal choice often has less to do with the intrinsic qualities of a technology and more to do with extrinsic factors. Those comments caused something of a stir with people coming out saying a variation of the following:

  • Light Rail is a scam.
  • Light Rail is awesome.
  • It depends. (Note: This is the camp I tend to fall in.)

Within the comments I disagreed with a commenter who referred to a “Light Rail Scam” but also admitted that “LRT has been foisted onto places that didn’t need it and probably shouldn’t have been built. But that’s not the case everywhere.”

Which prompted frequent commenter Matt the Engineer to question “What LRT lines weren’t needed and shouldn’t have been built?”

Very good question, Matt.

For readers interested in this issue, there are three essential articles they should look to (Note: clicking on the title of the article will allow you to download it):

The Pickrell piece is insanely readable for something as mundane as transit ridership forecasting. If you only have time to read one, this is the one you should look at. It gives a rather disturbing insight into how public transit is planned, funded and built in North America.

The Flyvbjerg piece, meanwhile, is a little more technical but nevertheless eye-opening. In fact, most of Flyvbjerg’s work is essential reading for anyone interested in how we (in)effectively conduct mega projects in the developed world, particularly in regards to public transit. If you take the time to work through his materials, you’ll come out the other end with a different mindset than when you entered.

The FTA piece, lastly, is boring beyond belief. But is great as a reference point to see how this all comes together. In it, you’ll find out which LRT systems in the US are the star performers (they’re not the ones you think), which are the true dogs (they probably are the ones you think), and which ones are middling at best (a few surprises).

If you’re a transit nerd, you need to read these.

What The Death of The Sydney Monorail Teaches Us About Techno-Zealotry

Dead Train Walking, The Sydney Monorail. CC image via Wikipedia.

On the recent news of the soon-in-the-offing death of the Sydney Monorail, Jarrett Walker at Human Transit had this to say:

Technophile commenters will doubtless chalk this up the Sydney decision as a defeat for monorails in general.  I disagree.  It’s a defeat for one-way loops, poor connectivity, and symbolic as opposed to actual mobility.  The monorail didn’t fail just because it was a monorail, but because it was a poorly designed line.

Couldn’t agree more. But I’d like to expand on those words:

Imagine, if you will, a 3.6 kilometre long light rail “loop” with 8 different stations and a flat fee to travel within it. Whether you travel one stop or all six it’s going to cost you roughly five bucks. The line doesn’t allow for integrated fare transfers between local subway or bus connections – not that you’d want to transfer to it as the line effectively takes riders from nowhere in particular to nowhere in specific.

Would you ride that system? Neither would I.

Of course I’m not talking about a fictional light rail system, I’m talking about the real Sydney monorail that was recently purchased by the New South Wales government and slated for demolition whenever “feasible.”

Some have come out showing this to be a definitive example of why monorail technology is somehow an inferior transit mode. A recent article at This Big City, is remarkably inane in its lack of analysis stating “the transit technology just hasn’t been a practical success. Today we have two case studies of cities where building infrastructure up doesn’t always mean moving people forward.” So not only are monorails not a practical success, but elevated transit in general is problematic.

Now I’m no fan of monorail technology as I’ve mentioned before. But my problem has little to do with the actual technology itself and more to do with maddening tourist-oriented installations (such as the Sydney monorail) that bear so little resemblance to actual public transit. Successful monorail systems such as the Wuppertal Schwebebahn, for example, I happen to be rather fond of.

But to return to my original question: Would any average commuter actually ride the above-described light rail line? Would they if it were a subway? A bus line? A gondola? Would they ride it no matter what the technology implemented was?

Of course not. No reasonable person would.

When we argue against a technology because of its inherent (dis)abilities, we have to make sure that our arguments are intrinsic rather than extrinsic to the technology in question. For example:

  • The fact that light rail vehicles must travel on a set of rails is intrinsic to the technology. Where those rails are located, whether in the sky, the ground or in a tunnel is extrinsic to light rail.
  • A monorail intrinsically runs either on top of a single concrete “rail” or is suspended from above by a single steel rail. Extrinsic to the technology is the fare charged for the line and the line configuration.
  • Intrinsic to gondola technology is the fact that intermediary/angle stations are currently required in order for cornering and turns to be realized. Beyond a minimum set of parameters; the size, design, shape and attendant functions of a gondola station are extrinsic to the technology.

See the difference?

Those items that are extrinsic to a technology are limited not by the technology, but by the choices made by the system designers and operators. Yes, extrinsic choices are sometimes limited by the intrinsic characteristics of a technology (for example, current gondola technology does not allow for more than about 8,000 pphpd), but those situations are more the exception than the rule. Where we get into trouble is when people argue against a technology intrinsically when the problems of the system are clearly extrinsic. (Note that I’ve made a very purposeful differentiation between “technology” and “system”.)

Consider perhaps the best example of this problem – Vancouver’s SkyTrain and Detroit’s Downtown People Mover. The two are polar opposites on the end of the success/failure spectrum yet both use the ICTS Mark II Advanced Rapid Transit technology. One system (guess which) is a perpetual money loser, suffers from terrible ridership, provides no free transfers from the existing public transit system, is a 4.7 km long loop through downtown and targets tourists rather than local commuters.

The other has been a roaring success, has witnessed massive expansion throughout the entire city, functions as mass public transit with free transfers between modes and targets local commuters rather than tourists.

Yet they both use the exact same technology. 

Unfortunately the extrinsic/intrinsic distinction is rarely made by techno-zealots and why celebrations about the death of the Sydney Monorail are disingenuous at best. At worst, techno-zealots use extrinsic arguments against other technologies as evidence of those opposing technologies’ failings. It doesn’t matter that it’s incorrect because that doesn’t change the fact that it happens – a lot. Sadly debate, argument and logical reasoning don’t tend to be a part of our high schools’ curricula so instead of reasoned commentary we get a kind of gangland, partisanship bluster that does nothing to advance conversation.

See! Monorails suck! They’re closing down the Sydney Monorail! Light Rail represent, yo!

Monorails aren’t useless any more than Vancouver’s Skytrains aren’t. The difference is that Vancouver’s Skytrains are treated as public transit whereas the overwhelming majority of monorails have been treated as poorly-thoughout-out tourist traps. It would be like arguing with someone that a football is a terrible kind of ball based solely on the fact that the vast majority of footballs in the world were being used as baseballs.

Nevertheless, that’s where the monorail stands. You can’t turn back history. You can’t eliminate all the missteps along the way. You can’t erase that episode of The Simpsons. Nowadays the monorail is like a disgraced politician. It doesn’t matter if he was good at his job or got thrown under the bus by a scheming associate or whatever. In the court of public opinion, he’s a scoundrel and a deviant and neither has much of a shot in an election. (Though the scoundrels tend to fare better than the deviants in that regard.)

That’s the reason I flee from monorails. They’re a technology with too toxic a reputation and much too much baggage to overcome. That might change sometime in the future, but not in the near future. Right now, monorails are Robert Downey Jr. in 2001 with no guarantee of an Iron Man in the waiting.

Is that fair? No, not in the least. But life isn’t fair and neither is marketing. Anyone who told you otherwise, lied to you.

Sounds of the Subway

The video “Bending Sounds” by Tim Sessler wonderfully captures the sites and sounds of the NYC subway. As the camera slowly meanders through the stations, people rush by, jumping on and off train cars, in and out of turn styles, and along subterranean corridors. The sounds of chatter and footsteps, and the rumble of the subway fade in and out as the camera approaches a number of subway musicians, each with their own sound, style, and charisma.

While the camera moves smoothly through the crowds, slowly, it inevitably passes by each musician, just as everyone around them does, so that each sound fades out just as quickly as it began.

Transit Aesthetics – AutoTram / BusRail

Can the AutoTram revolutionize the way we think about transit planning? Image from fotogalerie.verkehrsgigant-portal.de.

When a city plan is planning a new transit infrastructure project, a lot of time is often spent deliberating over which technology should be implemented. This discussion generally floats back and for between bus and rail (and more recently, sometimes even CPT). For many cash-strapped cities looking for quick wins and cost-effective mass transit solutions, the debate often settles on the mid-tier options, namely bus (BRT) and lightrail/streetcar opportunities (HRT tends to be too expensive and time-consuming to construct.) Amongst the many debate points — capacity, aesthetics, speed, cost, etc. — proponents of both technologies claim their technology is superior.

From my personal experience (your experience may be different), based on conversations with transit planners, engineers, operators and average joes, one of the biggest arguments in favour of LRT is its aesthetics. You can go on and on about all the capabilities and characteristics of modern bus technology, but in the end, a bus is still a bus.

But what makes a bus, such a bus? Its shape? Size? Look? Smell? Other than rubber on road vs steel on rail, what if a bus could be completely remodeled and redesigned to look and feel like LRT? Would this make it as attractive as LRT, and therefore able to attract just as much new transit riders as the rail systems claim?

The Fraunhofer Institute decided to find out. In 2005 they introduced the AutoTram – essentially a road-based LRT. The makers of this technology describe it as:

“… [it] combines features of conventional buses (e.g. high flexibility, low infrastructure costs and moderate life cycle costs) with the advantages of trams like high transport capacity, driving comfort and the possibility of partial emission-free operation.”

Could the AutoTram succeed and if it does, what does this mean for the future of light rail and transit planning?

World’s Largest Bus – Youngman JNP6250G – 300 Persons

Youngman JNP6250G - world's largest bus in terms of capacity. 300 passengers.

In recent news, various news media outlets (1,2,3) have reported that we’re about to see the world’s largest bus - Youngman JNP6250G in China. The official statistical breakdown of this public transit behemoth is as follows:

  • 300 person capacity (40 seats, 260 standing)
  • 25 meters (standard bus: 12m)
  • top speed ~80kph
Of course, as soon as this news story went online, the classic age old debate of “my bus is bigger than your bus” soon emerged. The Brazilians and Swiss have chimed in and proved that their bi-articulated buses are similar in length if not longer than their Chinese competitors (Switzerland: 24.7m and Brazil: 28m). Despite such similar bus sizes, the Chinese bus somehow beats their challengers in terms of maximum capacity (300 persons vs the 128 person capacity in Switzerland and 250 person capacity in Brazil). My initial guess for this discrepancy is that loading standards vary dramatically country by country.

Nevertheless, given the enormous capacity of these buses, it appears that it begins to challenge those coveted numbers seen in LRT systems. Let’s do a quick comparison:
  • Melbourne’s Bombardier Flexity Swift LRV: 150 
  • Minneapolis’ Bombardier Flexity Swift LR: 180
  • Calgary Siemens SD160NG: 226
If we directly compared these figures, the Youngman bus holds up to 2x the number of passengers in the Melbourne LRVs. 

 

So I understand that capacity is not the only thing important in building better and faster rapid transit networks. However, since we’re now able to manufacture such large functional modern buses and assuming building BRT infrastructure is more cost-effective than LRT, what’s preventing us from pursuing such transit initiatives in North America? Aesthetics? Comfort? Pride? Environmental concerns?

One of the Best Analyses of PRT You’ll Ever See

Image via swiftprt.com.

We here at The Gondola Project tend to be a pretty open-minded group of individuals with our readership generally following suit. We’re not, however, slaves to fads or trends. When we look at new ideas, innovations and technologies, we try our very best to be objective and analytical about them (but appreciate and love the craziness of things like the Chinese Tunnel Bus™).

We approach things from a position of empirical skepticism. We need to see that something can actually work - or at the very least, that the theory and logic underpinning a concept makes sound and reasonable sense. As a result, we’ve tended not to have a fondness for the mythologized panacea of the public transportation world; Personal Rapid Transit (check here and here for two of our more interesting debates with PRT advocates).

The fundamental logic behind PRT is quite simply flawed with most advocates of the technology blind to the economic and technological limitations of it. But that doesn’t prevent it from being continually trotted out as transportation messiah.

That’s why the work of blogger and researcher Apatzer is so fascinating.

Over at a brand new site called Swiftprt.com Apatzer meticulously (and sometimes exhaustingly) details the 6 months he spent researching and coding a simulated PRT network to investigate the technology’s feasibility.

His basic findings are that PRT is financially unfeasible; is incapable of providing the needed capacity in dense urban environments; and cannot provide the time savings over the private automobile typically sold by PRT advocates and companies.

I won’t go through his entire analysis as that would take about as long as it took him to do his study. As such, it’s hard for us to say whether his work is “right” or “wrong.” But for anyone interested in PRT as a viable urban transportation solution, they should spend a serious amount of time and energy exploring his work.
