As a general rule, road pricing isn’t popular. But that’s not because it doesn’t work. The problem is that it works too well, and people don’t like the idea of driving less and paying for roads (that currently have a zero marginal cost).

Here’s a recent study by Robert Bain and Deny Sullivan that looked at just how well it can work. In it, they examine 76 data points from 16 countries, including roads, bridges, tunnels, and cordons (areas).

The question: What happens to demand once the marginal cost of using a road goes from $0 to some cost greater than zero? (As part of this, they also looked at whether the road or bridge in question has viable alternatives.)

The results:

The median traffic reduction was 25%. But the interquartile range was -17% to -44%. This is all very significant. Said differently, the traffic impact in nearly a quarter of the examples was -45% or more. So almost a halving of traffic congestion.

These reductions are obviously a function of the cost of using each road, but regardless, the overarching takeaway remains the same: You may not like or want road pricing, but it totally works.

In Google's guide to its maps, there is a section on live traffic congestion, and in it, this image is used:

It is a map of the Toronto region, and not surprisingly, it is showing traffic congestion on the 401 highway. But what's interesting about this image is that there's no traffic at all on the 407 express toll route. (This is the green highway running generally parallel and north of the 401, for those of you who aren't familiar with Toronto.)

This is, of course, accurate. A 2019 study by the Canadian Centre for Economic Analysis called the Economic Impacts of Highway 407 found that, at the time, an average of 413,000 drivers were using the 407 highway each weekday. And of these trips, more than 85% of vehicles were travelling at or above 100 km/h. This translates into a traffic congestion index of almost zero.

During this same time, the highway 401 through Toronto showed that about 85% of vehicles were travelling below 50 km/h. Meaning, lots of congestion. This also had a significant impact on collision and fatality rates. On the 407, both were about half of what they were on the 401. (I couldn't find any more decent data, but if you have it, please share it in the comments.)

The reason for these differences is simple: the 407 charges for congestion. Here are the current per kilometer weekday rates for light vehicles travelling westbound:

Naturally, there are people who think the 407 is too expensive and that it shouldn't have been privatized. But the reality is that it works; really well in fact. And this is the only method that has been proven to reliably combat congestion. We can go ahead and spend a gazillion dollars building a new tunnel under the 401, and double the number of lanes (it's already 18 lanes at its widest point), but we already know that it won't solve our congestion problem.

Either we price roads and congestion, or we don't. But if we don't, then we need to be brutally honest with ourselves about the economic trade off that we are making: free/underpriced roads = traffic congestion, and accurately priced roads and congestion = less traffic. The choice is ours. But know, there's no such thing as a free lunch.

There are parts of Toronto that are pedestrian only. There's the Distillery District, some small laneways in Yorkville, the Toronto Islands (though this is a bit of a unique situation), and various other pockets around the city.

There are also streets that we temporarily open up to only pedestrians, such as Market Street and King Street, and areas, such as Kensington Market, that we have been rigorously considering pedestrianizing for as long as I can remember.

What is clear is that pedestrian-only streets are controversial. Motorists fear that it will make driving in the city even more inconvenient. And businesses fear that it will limit their customer base.

While it is true that not all streets can and should be pedestrianized, there are countless examples of streets and areas that appear to be thriving because of it.

Take, for example, Montréal.

Since 2021, the city has been pedestrianizing a stretch of 30 blocks along Mont-Royal Avenue during the summer months. And according to Mayor Valérie Plante, the commercial vacancy rate for the street has dropped from 14.5% in 2018 to 5.6% in 2023:

Maybe you don't want to infer causality here, but at the very least, it seems to suggest that the street isn't dying and bereft of human activity. This year, pedestrianization is also planned to be extended further into the fall.

This won't necessarily be the outcome for all streets, but I do agree with this recent Globe and Mail article that, oftentimes, the reasons for not pedestrianizing are "a question of philosophy, not geography." Because there's lots of research and data to support doing this.

If any of you are business owners along Mont-Royal, I'd love to hear about your experiences and how you think, for better or for worse, it has changed the area. Leave a comment below or drop me a line.
