Definitions

How you define a problem determines how you solve it.

Most transit agencies, planners and governments tend to define an urban public transit problem as a decision between Roads and Rails:

Should we use buses, light rail/streetcars or subways?

It’s no surprise then when buses, light rail/streetcars or subways are the end result. That’s what happens when you define a problem from its middle, rather than from its beginning. You get mediocrity, the status quo and exactly what you expect. Better instead to start the discussion where the discussion starts:

How do we move the number of people we need to move through a given environment as quickly, cheaply, safely and efficiently as possible?

Define a problem from its beginning and you’re bound to get more than just Roads and Rails.

Optimism Bias & Ikea on a Saturday Morning

Optimism Bias is the economic concept whereby humans make forecasts, predictions, budgets and schedules that overestimate the positives and benefits while underestimating the negatives and the risks. It’s unconscious and well documented. It’s one of the major reasons public works, transit and infrastructure projects are perpetually over-budget and not-on-schedule.

For example:

This morning (a Saturday no less), my girlfriend and I decided to go to Ikea. How smart was this? Not very. Everything you need to know about the awful side of humanity you can learn from one trip to Ikea on a Saturday morning. And I know this.

I know there’s going to be traffic. I know it’s going to be at least an hour’s drive. I know there’s not going to be a parking spot less than 1 km from the front door. I know it’s going to take me 15 minutes to find a bathroom. I know the line up for $1 hot dogs is going to be longer than the night is dark. I know I’m going to get into a fight with my girlfriend. I know I’m going to confuse the Billy with the Expedit. I know I’m going to need an hour of advanced calculus lessons just to figure out the 17 different components I need to build a desk. I know I’ll have difficulty choosing between Birch and Maple. I know I’m going to add twelve things to my shopping cart only to remove seven of them two hours later. I know I’m going to do that twice. I know it’s going to take the 14 year old salesman 20 minutes to confirm that the item I require to prevent my bookshelf from falling over and injuring me is not in stock despite what the computer tells him. I know I’m not going to be able to read the measurements I took at home because I scribbled them on the back of a napkin. I know half the cash registers will be closed. I know I’m going to have to go to some other counter to place a special order. I know I’m going to spend twice what I had hoped because those tealights were just too good of a deal to pass up. I know it’s going to take 30 minutes (minimum) to figure out how to fit whatever I bought into the back of the car. I know I’m going to need to go back in the store to get rope to tie the trunk closed. I know I’m going to have to stop for gas because that’s just how far away Ikea is.I know it’s going to take me days to allen key together all this stuff. And I know I’m going to have to go back there the very next day to buy the legs that should’ve been included with my table but for some reason are sold separately.

I know all this. I know it like gospel. Ikea on a Saturday morning is like taking candy from strangers. You just don’t do it. Ikea on a Saturday morning is Ikea for an entire weekend. It’s a zero sum game. And yet despite knowing this, I wholeheartedly believed that we could get to Ikea and back with plenty of time to get a blog post up by lunch. Right, Steve, right.

So please accept my apologies for the lateness of this post. My optimism got the better of me.

Medellin/Caracas, Part 7

Two weeks ago I travelled to Medellin, Colombia and Caracas, Venezuela to tour five of the most important CPT systems in the world. This is Part 7 where I discuss the social mandate that underlies the Caracas Metocable. Image by Steven Dale.

If you’ve been paying attention, you’ve probably noticed something problematic about the Caracas Metrocable: The stations are enormous. We’re not talking about just “big” here. We’re talking about “big enough for Cirque du Soleil to perform in.”

This is because the stations themselves are not really stations at all. Whut? Exactly.

In actuality, the Caracas Metrocable stations are full-service community centres with multiple neighborhood facilities all under one roof including a Cable Propelled Transit line. Most of these facilities are not yet complete and as such the stations have an eery empty quality thus far. The plan, however, is to have gymnasiums, markets, dental offices, police stations, medical clinics, theatres, libraries and all other manner of social services located within the 5 stations united by the Metrocable.

The idea is to have each station host one or two such facilities. As each station is linked to the other via Metrocable, those within the poor barrios can travel quickly and cheaply between those services in a way that simply would not have been possible before the Metrocable. When you consider this component of the plan, the Metrocable is less a transit line and more the connective tissue that holds together a network of social services.

Whether or not you agree with the political ideology behind Hugo Chavez’s plan, you have to admit it’s bold and unique. It’s also costly. The price of the Metrocable including stations/community centres has been reported as $265 million USD and I’ve heard numbers as high as $300 million USD. Considering the system is only 1.8 kilometers long, you could practically build a subway for that price.

The price of the gondola system, however, was modest. Everything necessary for the gondola system (the “electro-mechanical” cost in industry-speak) was only $18 million USD.

Consider that for a moment: Only 6-7 % of the total cost of the Metrocable went to the transit system and infrastructure itself. The rest was spent on the stations/community centres and land expropriation costs.

I want to state this plainly so that no one opposed to the concept of cable transit can use Caracas as an example of how expensive the technology is: The Caracas Metrocable did not cost $300 million. It cost $18 million. The additional monies spent were on community centre facilities and land expropriation costs that were separate from the transit system itself.

Once again (because the internet is great at taking people out of context): The Caracas Metrocable did not cost $300 million. It cost $18 million. The additional monies spent were on community centre facilities and land expropriation costs that were separate from the transit system itself.

Should some of those additional monies be allocated to station costs? Yes, but not the vast majority of it. The Medellin Metrocable (which uses similar MDG technology) Linea K cost $26 million USD in 2006; that included 1.8 kms of length and 4 stations. Linea J cost $50 million USD in 2008; that included 2.7 km and 4 stations. Linea L cost $25 million USD in 2010; that included 4.8 km and 2 stations. It would be fair to allocate an additional $10 – $20 million dollars to the cost of the Metrocable itself, but no more than that.

As a social experiment, it will be interesting to see how the Caracas Metrocable pans out. I, for one, am hopeful. Caracas needs these kinds of services, particularly in the barrios. One thing, however, I’m not certain of is the overt social message of the Metrocable. Many cabins are adorned with single word imperatives suggesting qualities which those in the barrio should aspire to and exemplify:

Sacrificio . . . Moral . . . Libertad . . . Equidad . . . Humanismo . . . Amor . . .

It’s an odd design choice that has nothing to do with the technology itself. But as one rides the Metrocable or sees them glide overhead, one can’t escape this blatant messaging. Granted, it’s hard to argue with the message: Sacrifice, Morals, Liberty, Equality, Humanity, Love. But at the same time, is it a transit agencies job to suggest how to behave? Maybe, maybe not.

In the western world we’re used to being told how to ride our transit. Hold the handrail. Exit by the rear doors. Don’t spit. Don’t litter. Give up your seat for the elderly. Mind the gap. These instructions transit agencies force upon us are nothing more than the practical application of the emotional instructions the Caracas Metrocable forces upon its riders.

Maybe we wouldn’t need so many rules and instructions in our transit systems if we simply had signs that read “Love” or “Equality.” Or not, I don’t know. It’s something I’ve wrestled with a lot since seeing it. Is it propaganda? No. But it veers pretty close to it and that’s what makes me uncomfortable. The message plays so blatantly upon emotions and that’s problematic. But at the same time, the sweet naiveté of the gesture is charming enough, innocent enough to catch even the most cynical observer off-guard.

I honestly don’t know. I’d love to know what everyone else thinks about this matter. Take a look at the images below and form your own opinion: Are the messages on the Caracas Metrocable propaganda? Are they amusing and pleasant? Are they harmless? Are they dangerous? What do you think?

Medellin/Caracas, Part 6

Two weeks ago I travelled to Medellin, Colombia and Caracas, Venezuela to tour five of the most important CPT systems in the world. This is Part 6 where I discuss the technological innovations of the Caracas Metocable. Image by Steven Dale.

Like the Medellin Metrocable, the Caracas Metrocable is a MDG system, the most basic of aerial Cable Propelled Transit technologies. It is fully-integrated into the local Metro system, has a maximum operating speed of 18 km/hr, a capacity of 3,000 pphpd and is 1.8 km long. Vehicles can carry 8 sitters and 2 standees. The system has 2 terminals and 3 intermediary stations; a total of 5 stations. Unlike the Medellin systems, which were built by the French-Italian consortium of Poma-Leitner, the Caracas Metrocable was built by the Austrian-Swiss partnership of Doppelmayr/Garaventa.

The most important aspect of the Caracas Metrocable is its alignment. The Caracas Metrocable’s alignment includes two extreme 90 degree turns. That this was the first aerial cable system in known history to implement a 90 degree turn is impressive, that the designers had the guts to attempt two 90 degree turns is all the more so. With this single act, the cable transit industry has demonstrated their ability to adapt, innovate and improve upon their technology within the public transit market.

What’s more, engineers did not utilize a separate drive wheel at each angle station as is common in most corner-turning applications. Instead, engineers used a single, passive deflection bullwheel at the two 90 degree stations, dramatically reducing complexity, size and cost of the system. Only at the middle station is a second drive wheel utilized. This, in essence, means that the Caracas Metrocable is made up of two separate lines where vehicles switch automatically from one line to the second at the middle station.

A graphical representation of the Caracas Metrocable system. Notice how the system is made up of two separate lines (represented by two different shades of blue). If one line fails, vehicles can be re-routed back onto the original line. Image by Steven Dale.

Additionally, a mechanism was designed into the middle station that allows operators to divert vehicles such that they do not automatically switch onto the new line, returning instead from whence they came. This configuration creates enormous additional benefit from an operations perspective. In the even that either of the two lines were to experience mechanical difficulties, the second of the two lines would be able to continue operations.

This simple feature debunks the common (but provably misinformed) opinion that with cable technology when one part of the system goes down, the whole system goes down.

Further features add to the Metrocable's appeal: Two way intercoms are located in each vehicle to assist with safety and emergency situations. Image by Steven Dale.

Medellin/Caracas, Part 5

Last week I travelled to Medellin, Colombia and Caracas, Venezuela to tour five of the most important CPT systems in the world. This is Part 5 where I introduce Caracas, Venezuela's brand-new Metocable. Image by Steven Dale.

The Caracas Metrocable, Introduction

Imitation, they say, is the greatest form of flattery. And if that’s the case, then Caracas is clearly smitten with Medellin. Inspired by Medellin’s incredibly positive experience with Cable Propelled Transit, Venezuela has embarked on their own CPT campaign, beginning first in the capital city of Caracas.

Like Medellin, Caracas exists in a narrow mountain valley. It is crowded, dangerous and littered with impoverished, poorly connected hillside barrios. It is an ideal environment for CPT. But the similarity ends there. So much is similar between the Medellin and Caracas Metrocables (not the least of which is the name), it would be easy to ignore the differences. But those differences are many and dramatic. The two systems are both cousins and rivals, synonyms and antonyms. The Caracas component of Medellin/Caracas will partly focus on those differences.

One difference between the Caracas and Medellin situations must be stated up front: While both cities (like all cities) suffer from traffic congestion, one is typical (Medellin) and the other is a complete and utter basket case (Caracas). See, Venezuela is a net exporter of oil whose central policy is to subsidize petrol prices. This policy results in Venezuela having the cheapest gasoline on the planet; 12 cents per gallon (USD)! Consequently, the roads of Caracas are a traffic nightmare the likes of which would make North Americans pine for the rush hour gridlock they are typically accustomed to. A trip of a half dozen kilometers can take (literally) hours. Traffic lights, lane demarcations and signals are ignored and pointless. Bumper-to-bumper is a ridiculous understatement.

In other words, Caracas needs cheap public transit outside the right-of way of the private automobile in a way that one needs to witness to appreciate. It could rightly be called a crisis. The Metrocable is part of the solution to that crisis.

As the Caracas Metrocable opened mere weeks ago (it had been out of testing for just two weeks during my visit), it is impossible to discuss the “success” of the system, only it’s existence. But the fact that it exists at all is important. That the world doesn’t know it even exists, more so.

The photos you’ll see here over the next few days are unique. I was afforded time to speak with technicians, operators, designers and salesmen associated with the Metrocable and given free reign to photograph and videotape as I saw fit. Please lead people to these next few posts. Anyone associated with or interested in public transit needs to see them.

Hopefully you find the Caracas Metrocable as inspiring as I did.

‘Make No Small Plans’

That’s what the famous American urban planner Daniel Burnham is often-quoted as having said. Make no small plans. We teach our planning students this edict like its religion. But how many big plans, grand plans, enormous plans are ever actually realized?

Few, and rarely as per the original design.

Big plans are cumbersome beasts. They are easily thwarted by political inertia, economic change and elections. Big plans just don’t work in the financial, social and political reality of today.

Imagine if Medellin had tried to plan and build three Metrocable lines all at once. How long would that have taken to plan? How easy would it have been for opponents of the project to simply delay until a new Mayor came into office? What if the Colombian economy collapsed? How likely would that plan have fallen apart?

Instead, Medellin started small. One cable transit line, 1.8 kms long. Simple, easy and modest. Yet even still, from idea through to completion it took 6 years. But they got it done. They were successful precisely because they started small. And because they got it done, because they were successful, now they open a new cable line every other year with ease. Medellin’s a lesson not just for cable, but for public works projects in general.

To realize big plans, you have to accomplish small plans first. Stop planning the big. Start doing the small.
