Paris has a massive transit project that is currently under construction called the Grand Paris Express. It consists of 4 new metro lines, 1 line extension (at both ends), 68 new stations, and 200 km of new tracks. The first phase was the extension of Line 14. That opened last year. And the new lines are planned to open in stages up until 2031. I have no idea if they're on schedule and/or on budget, but here's a map of the GPE project:

Here's what it looks like if you overlay all existing metro lines (note how concentrated they are in Paris proper and how they're clearly designed to bring people into the core):
Here's what it looks like if you overlay all existing tram lines:
And finally, here's what it looks like if you overlay all existing RER lines (suburban rail):
At this point, the map is getting visually pretty cluttered. But if you look at how the GPE lines compare to what's existing, I think you'll start to see just how important this project is for the Métropole du Grand Paris (or Greater Paris). It creates a new set of concentric rings in the inner suburbs and, for the first time, it will allow Parisians to travel around the region (via rail) without first passing through the core of the city. So it's in effect both an expansion and a stitching together of the city.
But let's put some numbers to this.
According to a recent memo by Apur, which looked at the economic composition of the station areas, about 21% of all salaried employees in Grand Paris are located next to one of the new 68 stations. As a total number, this works out to about 934,000 employees (2022 figure). And included in this figure is La Défense, which is the office district where Paris decided to put most of its tall buildings. This has the highest concentration of jobs at approximately 163,599 salaried employees (again, 2022 figure).
Another way to think about these station areas is that they represent what many are now calling New Paris. This is a part of Paris that is less encumbered with history and, therefore, more open to change and new ideas. This creates an exciting opportunity, and already we're seeing that take hold. Later this week on the blog, I'll talk about a specific project in Greater Paris that is currently under construction and that I was fortunate enough to tour on this trip.
The other day I was speaking to a Korean friend of mine and he was telling me about Seoul's new GTX-A commuter railway line. This line opened at the end of 2024 and is part of a broader Great Train eXpress initiative that includes 3 lines (A, B, and C) and that is intended to establish a new "30-minute commute zone" surrounding Seoul. A is the first line to open. C is scheduled for completion in 2030. And already, three more lines are now being planned: D, E, and F.
What this first line has accomplished is pretty extraordinary. GTX-A connects Paju in the north to Seoul in the south. Paju sits at the northern border of South Korea (and therefore houses many US and South Korean Army bases) and has a population of over half a million people. Prior to GTX-A opening, this commute used to take approximately 90 minutes by conventional subway and up to 90 minutes by car, depending on traffic.
Today it takes exactly 22 minutes! If you're interested in seeing a complete walking video of this commute, click here.
The GTX system is a higher-speed railway line. Meaning, the trains are designed to operate up to a maximum speed of 180 km/h. Average speeds vary depending on the segment and stop spacing, but it seems to operate at an average speed of
New York City was supposed to terminate its congestion pricing program last Friday because, well, Trump told them to. But they didn't do it and so harsh words were exchanged and then the deadline was extended for another 30 days. (This sounds oddly familiar.) Who knows what happens next month, but we are able to accurately quantify the benefits of nearly 3 months of congestion pricing.
Firstly, it's generating a lot of money. In the first two months of operation, congestion pricing has already brought in over $100 million in new revenue for the city. This is important because it's money that can be used for transit and other infrastructure improvements.
Equally important is the fact that this money was generated by creating measurable value for drivers. For all of the river crossings that lead into the CBD, average weekday travel times this past January are lower compared to January 2024. And in some cases, they're lower by a lot. The Holland Tunnel, for example, saw travel times drop by 48%.
Lastly, it's encouraging more people to take public transit. Here's a chart from Sam Deutsch over at Better Cities showing the increases in ridership since the program was implemented:

What this also means is that, as new GTX lines continue to come online, the geography of the Seoul urban region will continue to get redrawn. Suburban regions that were previously far out, are now going to get "pulled in" and function as more integral parts of a contiguous city. This improved access should also alleviate housing pressures by effectively opening up more supply.
I mean, 22 minutes is nothing. It can take longer than this to travel 3 blocks on a Toronto streetcar during rush hour. GTX is a prime example of the magic of rail and what's possible once you accept that highways (and tunnels underneath them) aren't going to be what efficiently move the most number of people around a big global city.

The MTA as a whole is now averaging about 448,000 more public transit riders per day. And to put this number into perspective, Sam reminds us that Washington DC has the second most-used public transit system in the US and that it sees an average of about 304,000 total riders per day (January 2024 figure). So in other words, New York's congestion pricing bump alone was nearly 1.5x DC's entire ridership base.
Some critics will argue that NYC's subway is dangerous and that this program unfairly pushes people toward it. But crime data suggests otherwise. New York's subway also saw over a billion rides in 2024! So I don't know how you argue that less people should be taking it. It's pretty clear that this is what moves the city. Imagine if the above went the opposite way and 448,000 more people started driving to work.
Some people may not like it, but the reality is that congestion pricing is doing exactly what it's intended to do: reduce traffic congestion, make money, and encourage more sustainable forms of urban mobility.
