“We shape the cities, and then our cities shape us.” That’s one of my favorite lines from the documentary The Human Scale, featuring Danish architect and urban designer Jan Gehl. I like it because I don’t think many of us think enough about the way in which the built environment – that we create – ultimately goes on to influence the way we live our lives.
One of the most interesting connections for me is the link between urban form and public health. There’s been a lot of talk over the years about how suburban sprawl is, or might be, making us fat (among other things). We’ve created environments that are only navigable by cars and that has forced many of us into sedentary lifestyles. We sit in our cars, and then we sit in our offices.
So today I’d like to conduct a bit of a poll. If you’d like to participate, please share the following 3 things in the comment section below: 1) your city, 2) the type of neighborhood you live in (urban, suburban, rural, etc.), and 3) the amount of time you spend walking or doing something active on an average day.
Here’s me:
I live downtown Toronto in the St. Lawrence Market neighborhood (urban). I take the subway to work and the station is a 10 minute walk from my place. So as a bare minimum, I spend at least 20 minutes a day walking. But since I also walk to do most of my regular errands, and since my gym is another 10 minute walk from my place, I’d say I average a good 30-45 minutes of walking each day.
Now it’s your turn :)
This is a pretty crude survey, but with the advent of things like smartwatches and health monitors, I think we’ll soon have lots of great data on the ways in which our cities might shape our health.

Right now the Toronto International Film Festival is going on in the city. It’s actually one of my favorite times in Toronto. There’s so much going on and the city generally does things that it doesn’t normally allow, but that it should do all throughout the year, such as extending last call at bars and closing down streets to cars.
This year, King Street between University Avenue and Peter Street has been made pedestrian-only. It encompasses an area known as the Entertainment District and includes the Bell Lightbox, which is the TIFF HQ. The street was closed last Thursday and will reopen this Monday. So it’s a 4 day thing, that TIFF is calling “Festival Street.”
Some people – like me – are really excited about this. Here’s s picture I tweeted out on Thursday night. Given the engagement (retweets/favorites), I think there are others who feel the same way I do:
Pedestrian only King Street for #TIFF. Look at this magic! #athiscity pic.twitter.com/KVR7t2Irvs

But there are others who are furious that their commute was disrupted last week and that we’re inconveniencing locals for the sake of hosting one of the top film festivals in the world. (King Street typically moves about 60,000 people per day on the streetcar and 20,000 vehicles.)
But when I walked the entire 650 meter stretch on Thursday night, it was completely full of people. There were people playing large-scale chess. There were people eating at picnic benches. And there were lots of people just enjoying a wonderful summer stroll in the city.
And all I could think about is that this is an unmet need in the city. King Street is a wonderful place to be right now and we don’t have an equivalent during the other 361 days of the year here in Toronto. So rather than be upset that we’ve closed down 6 blocks of downtown, I’m only upset that we don’t do more of this and make it permanent during the rest of the year.
I’m not necessarily saying that King Street is the best place to do this. Yonge Street initially strikes me as being a better place to start. But I am saying that if we have to reconfigure things to make our city more awesome for when guests come over, that maybe we should think about how to make it more awesome all the time.
Last week The National Post published an article talking about Toronto's Crosstown LRT and how it’s spurring a wave of development all along Eglinton Avenue. Below is a map, taken from that article, showcasing some of the developments that are currently in the pipeline and awaiting the Crosstown’s opening date of 2020.
Not surprisingly, developers like transit investment. But more specifically, they like fixed track transit investment. Rarely do new bus routes elicit the same sort of response that you’re seeing above. And that’s because fixed track investment has permanence. If you’re going to go long on an area, you want certainty.
As the Crosstown tunnel boring machines move across midtown Toronto, I thought it would be interesting to look at a transit concept that I first learned about through Jarrett Walker’s Human Transit blog. It’s called: the radius of demand.
One of things that transportation planners look at when designing and building a new line is the spacing of stops. Typically, as you move from buses all the way up to subways, the spacing between stops and stations increases. Spacing is always a bit of a trade off though, because more stops means easier access for riders, but it also means slower overall service. Somewhat famously, Paris designed its metro system so that you’re rarely more than 500 meters away from a station.
Once you have your station locations, it’s quite common to then draw a radius around each stop to simulate the catchment area. In other words: How much of the city can I service with this station and how far will people be willing to walk in order to get there? However, this distance, which is the radius of the circle, usually depends on the type of transit. Oftentimes people are willing to walk further in order to get to faster transit service.
But what’s most interesting about this radius of demand is that it’s entirely dependent on the fabric of the city. Take for example, the following two maps from Seattle, which I have taken from Walker’s blog. On the left is a suburban setting and on the right is a downtown setting. In both cases, the red circle represents a 1 km radius.
Now, if humans could fly over barriers, such as highways, and every Seattle resident was willing to fly exactly 1 km to a transit station, these two radiuses of demand would be perfectly accurate. But since that’s not the case, we instead need to look at what actually represents a 1 km walk – those are the blue lines in each image.
Because once you do that, you realize that the cul-de-sacs and highways on the left make it impossible for most of that radius of demand to actually walk to the station in under 1 km. So the catchment area actually becomes much smaller. On the other hand, if you look at the image on the right, you’ll see that the tried and true city grid is actually remarkably efficient for walking. Almost all of the circle is serviced.
So as the Eglinton Crosstown LRT makes its way through the center of Toronto, I think it’s important to keep in mind that it’ll be cutting through quite a few different kinds of street grids. Some of them will be highly conducive to transit usage and others not as much. And in many ways, this is one of the greatest challenges of transit investment. The track itself is only one part of the puzzle.
That’s why the City of Toronto is also undertaking a planning exercise called Eglinton Connects. Its intent is to leverage the opportunities, as well as address the challenges, that will result from Metrolinx’s Crosstown LRT. If you’re interested in the future of Eglinton Avenue, you should consider getting involved. Oftentimes it’s only the critics that speak up. But that’s not the best way to build anything.
