Last weekend a friend of mine sent me an article from The Economist talking about why trams, streetcars, and light rail are a waste of money. The argument is basically that steetcars are expensive, less efficient, and that – despite North America’s renewed interest in them – we should instead be spending our scarce public dollars on more buses.
Here’s a snippet from the article:
…but cash spent on streetcars displaces spending on other, more cost-effective forms of public transport like buses, which offer cheaper and more-efficient service but are considerably less sexy. The capital cost per mile of a streetcar is between $30m and $75m, while a rapid bus service costs anywhere between $3m and $30m, according to the American Public Transportation Association.
Now, there’s no question that buse routes are initially cheaper to implement. You don’t have track to build. But I don’t agree that the cost structure is quite that simple if you consider the number of people you need to move in your city. I struggle to see buses as a more efficient service.
The big difference between modern light rail and buses is capacity. Toronto’s new streetcars will move about 3 times as many people as your typical bus. So you’d need to triple the number of buses and triple the number of drivers – adding to your labor costs – if you want to have a chance at moving the same number of people.
Streetcars are also electric, which means they run on a renewable energy source. We’re in the process of making this switch with private transport, so why go backwards when it comes to public transport? You can certainly run electric buses as well, but then you’re building overhead power lines and bringing up your initial costs.
I think the challenge is that when people think of light rail, they think of slow lumbering streetcars. I agree that many of these lines are inefficient and I’ve written about it. But there are a number of ways to implement light rail. And when done well it can efficiently move a lot of people for costs that are far less than a subway.

Here’s further evidence that technology is starting to infiltrate into many other industries, including architecture. London-based architect and designer Pernilla Ohrstedt is currently working on an exhibition for Dezeen and MINI Frontiers that will architecturally visualize the 3D data that driverless cars collect in order to navigate around.
I had never thought of this before, but as a byproduct of driverless cars, we’re about to start collecting detailed replicas of all of our cities – well beyond the static images we currently have with Google Streetview. In order to navigate by themselves, driverless cars are constantly scanning their surroundings to create a “point cloud” replica of the built environment. This point cloud basically tells the car where they are, where they should drive, and what obstacles might be around.
It could look something like this:
Already there are firms like ScanLAB emerging to provide 3D scanning, publishing, and visualization services. But this is obviously just the tip of the iceberg. I can only imagine what innovation will emerge from the passive collection of all this data once driverless cars become commonplace in our cities.
As one example, it could be a way for us to systematically measure the correlation between the qualities of a street and the vibrancy of its street life. Is there a perfect width? An ideal traffic volume? A right scale? All of this data could make city building more of a science (and perhaps less political).
My hope though is that this data would be open and accessible to all, so that clever entrepreneurs could build on top of it.
What are some of your ideas?

I was out for a bike ride last night and, on my way home, I decided to try out the new dedicated bike lane on Adelaide Street. Usually I would take King Street, but it was completely full because of Caribana parties.
For those of you who may not be aware, the city of Toronto is currently piloting two dedicated bike lanes on Adelaide Street and Richmond Street in the downtown core. Both streets are one-way and because the lanes were so big to begin with (highway-like spacing), I’m told that these new bike lanes didn’t even eat up a driving lane.
Here’s a map of the pilot area:
Given that dedicated bike lanes are a scarce resource here in Toronto, I have to say that it was rather luxurious having my own piece of road. And because there’s no longer any fear of parked car doors swinging open, I was able to ride a lot faster than I normally would.
But as my friend Evgeny pointed out earlier this week, there’s a big difference between dedicated and grade separated bike lanes. Indeed, on my trip from Bathurst Street to Church Street last night, I encountered 3 cars parked in my lane.

So, I hope that these bike lanes become a permanent fixture downtown, but that the city makes them grade-separated. I’m sure people will use them. At the same time, I think they could also act as a catalyst for more pedestrian life along both of these streets.
If you haven’t yet tried them out, I would encourage you to do so. The city is tracking usage and so you would be supporting the cause. And if there’s anybody parked in your lane, below is one way to handle it. It’s a video by Casey Neistat out of New York. If you can’t see it below, click here.
