For a very long time, there was a great debate in Toronto about whether or not the elevated Gardiner Expressway should be removed from downtown and replaced with something else. As recently as five years ago, that debate was centered around removing the eastern portion of the expressway and replacing it with a large surface boulevard.

But that ship has sailed. A controversial decision was made not to remove the "Gardiner East," but instead reroute it (that wasn't my first choice). At the same time, wonderful new city building initiatives, such as The Bentway, have started to reclaim the long overlooked spaces that sit underneath it.

Another good example of this is the "West Block," which was recently unveiled at the northeast corner of Bathurst St and Lake Shore Blvd W. New retail uses (such as the above LCBO) and new public spaces (note the above stair/seating combo) have been tucked underneath the expressway's structure, creating a beautiful contrast between old and new.

It reminds me of some of the urban spaces that you might find in other dense urban centers such as Tokyo, because this may be the first fully fledged retail space located underneath the Gardiner. I think it is. But here's what's counterintuitive: the more we embrace the Gardiner in these ways, the more it will recede into the background.

At some point in the near future, these spaces will be filled with people. People eating outside at restaurants. People sitting on the above steps enjoying an illegal drink (because of our antiquated liquor laws). And when that happens, I'm sure most won't even consider what's above their head.

On Saturday, Toronto closed a few of its major roads, including Lake Shore Boulevard West, to provide more space for outdoor activities and social distancing. A number of "quiet streets" were also created last week. These now only allow local vehicular traffic. This, of course, isn't anything novel. Most cities around the world have been reallocating their public space in the wake of this pandemic, with many hoping that some of these changes will stick.

I rode my bike out to the Humber Bay Shores on the weekend (where I took the above photo) and it was clearly the fix that we needed. Our current waterfront trails simply cannot safely accommodate the volume of people who are out right now on the weekends. I reckon that, under normal circumstances, a good percentage of these runners, cyclists, and rollerbladers would probably be on a patio drinking. That's not possible right now, so demand for outdoor activities is way up. (Entirely unproven theory.)

But as is always the case, changes like this make a lot of people grumpy. Traffic got backed up on Lake Shore and the regular "war against the car" narrative flared up. I'm not sure where all these cars were going, but they were out in the sunshine trying to go places. So we have a situation where the reallocation of public space has flipped the supply and demand imbalance to another user -- drivers. Now it's us versus them: "Isn't there already more than enough room on those big bike trails?"

I'm frankly tired of this never ending debate, which is why I have argued before that we could use better data and better metrics. How many people are we moving with the decisions we are making? How many people are we accommodating per square meter of space? Where are users of this public space coming from? What performance standards are we trying to meet and/or maintain? What is the most equitable allocation of a finite amount of space?

But perhaps I'm naive to think that people might listen to facts.

When I was a kid I remember my parents having something called a “Perly’s” in their car. It was basically a map book and it was the best thing around. 

You would start by looking at a big grid of the city and then you’d find the specific area you were looking for and then flip to that page. If you were on the road a lot for work, a Perly’s was a mandatory addition to your car.

Things have obviously come a long way since then. It could take you a long time to find the street you were looking for in a Perly’s. I remember doing that from the passenger seat. Now our phones do that for us and if the connection makes us wait for more than few seconds, we get irritated.

But we’ve also moved beyond just static maps. 

The other morning I was driving out to the suburbs and I saw this road sign telling me that – given current traffic conditions – it was going to take me 15 minutes to get to HWY 427. 

Have you ever wondered how they come up with those time estimates?

There are a few ways to do it. But here in Toronto along the Gardiner Expressway and Lake Shore Boulevard it’s done using your mobile phone. Phones have unique network identifiers called MAC addresses. And when they try and connect via Bluetooth or Wifi they actually send out their MAC address.

So what happens as you’re driving along is that your phone’s MAC address is being picked up at various locations. And since the distance between these various reception points is known, it’s pretty easy to determine how fast you’re traveling. That’s how they come up with those time/traffic estimates. 

This data is anonymous but, in theory, the city also knows if people are speeding when the traffic is light.

This same technology is being used by many retailers and shopping malls to track how people move through their spaces. It’s used to see, among other things, which merchandising strategies are working and what synergies one might be creating (or not creating) with the tenant mix.

But getting back to traffic, there are obviously ways to collect traffic data without any additional physical infrastructure.

As I was about to leave the suburbs and head back downtown, my phone somehow knew I was about to do that (perhaps because I was stopped at a Starbucks near the highway) and so it decided to tell me this:

It wasn’t the best notification to receive on my phone, but I was impressed nonetheless. This traffic data is collected using GPS data transmitted from mobile phones using Google Maps, Apple Maps, and so on. Clearly we’ve come a long way since the days of manually leafing through a thick Perly’s.

At the same time, it feels like we are still pretty far away from solving the problem of urban congestion. Every big city in the world is grappling with this issue. 

Part of the problem, I think, is the belief that there’s some sort of silver bullet – more highways, a magic smartphone app, and so on – that will enable everyone to be able to drive around in their own car by themselves. I don’t believe that’s possible in big cities. And the sooner we get away from that toxic thinking, the quicker we’ll solve this problem.
