Love them or hate them (I happen to love them), Toronto's streetcars are part of this city's identity. Most North American cities got rid of their streetcars around the middle of the 20th century. But Toronto didn't. And that has left us with the largest first generation streetcar network in the Americas in terms of total track length, number of cars, and ridership. That's something. If you're also a fan of streetcars (or just like geeking out about cities), you may enjoy this little ode to Zürich’s tram network by Monocle. It's called, "My life as a tram."

Joe Berridge's recent opinion piece in the Globe and Mail makes the case for why Shanghai is destined to become "the capital of future." Brash city building, massive scale, and entrepreneurial hustle are among some of the reasons why he believes the city is on a path to global supremacy. And similar to other great capitals, it has benefited from a strategic geographic position on an important waterway -- in this case the Yangtze River.

By way of comparison, Toronto is said to be the fastest growing urban region in both North America and Europe right now. We add somewhere around 125,000 people each year. Shanghai, on the other hand, is adding between 700,000 and 800,000 people each year -- much of it from internal migration. The city currently has a population of around 24 million people and it is expected to grow to somewhere between 35 and 45 million people by 2050. (Figures from the Globe.)

Notwithstanding all of our successes as a global city region, as I was reading Berridge's piece I couldn't help but come back to this comparison. Shanghai opened its first subway line in 1993. Today it has one of the most extensive networks in the world; whereas, it would probably take Toronto this long to figure out if that first line should be light rail or a below-grade subway. And we haven't even gotten to the number of stops yet.

But that's one of the differences between top-down and bottom-up city building: speed.

Starting in the late 1930s, New York City began hiring photographers to document each and every building in the city. It did this to improve the accuracy of its tax assessments, and so every photo was taken with a sign board indicating the building’s block and lot number. The photos looked like this (taken from here):

The initiative produced over 700,000 black and white photos, all of which have been recently digitized according to the New York Times. The Times also recently published this interactive piece where they go back to these archival photos to see how the city has and hasn’t changed. 

In the late 1930s and early 1940s, documenting a city and its buildings was clearly a manual endeavor. Today we have Google Street View (launched in 2007), which has now photographed much of the world. Many countries, including all of North America, are reported as having “mostly full coverage.”

But already autonomous vehicles (and their supporting services) are starting to scan and map our cities in new ways. So it will be interesting to see what ends up getting built on top of this data. I am certain it will empower much more than just better tax assessments.

Happy New Year, friends. Thanks for reading over the last year.
