Paris introduces new limited traffic zone

As counterintuitive as it may sound, one way you could try and improve traffic congestion is to discourage people from riding their bikes and instead encourage them to drive more. That’s what’s happening in Toronto right now. Another way is to dramatically restrict car usage. And starting this Monday, that’s what Paris will be doing with its new limited traffic zone (zone à trafic limité) in the center of the city:

This new ZTL is approximately 5 square kilometers. About 100,000 people live within its boundaries, and it is estimated that somewhere between 350,000 to 500,000 vehicles enter it each day. But according to the city, it is estimated that only around 30% of these trips are absolutely necessary (because of a lack of alternatives, for example). The purpose of the ZTL is to reduce the unnecessary ones.

The way it will work is that drivers will no longer be allowed to drive through this zone. You’ll only be able to enter if you plan on stopping for a legitimate reason. It’s not yet clear what this exact list of approved reasons will be, but the general idea is that if you want to drive in for dinner or to attend a meeting, that’s fine. What you can’t do, though, is just drive around in a souped-up Honda Civic blasting Taylor Swift.

The next 6 months are planned to be a period of education. Drivers exiting the zone are just going to be told that there’s this new ZTL and that they better have stopped somewhere. But eventually there will be a 135 euro fine and eventually drivers will be expected to furnish some sort of supporting evidence for their stop, such as a restaurant receipt. There’s also talk of adding automatic cameras.

Of course, this creates a lot of gray areas. What about if you’re just going over to a friend’s place for dinner? Will they then need to write you a note saying that you went over for some homemade bouillabaisse? Yeah, I don’t know the answer to this. But you have to admit that this is a bold city-building move, and a far more effective way of improving traffic flows.

Unlike removing bike lanes, this plan will actually work.

    I’m surprised there was no ZTL here before. There are lots of Cities in Italy that have ZTLs or something similar. When we were looking at AirBnBs, I believe there was a procedure for how you get access to the ZTL. In some case, there are no physical restrictions and just cameras so you just get a ticket in the mail down the road.

      Based on the above Le Parisien article, it sounds like Italy is doing it through video cameras. I experienced something similar in Bordeaux this past summer, where access was controlled through bollards and you had to buzz in.

    There was an image I had seen many years ago as a student that left a lasting impression on me. It showed the amount of road space required to transport 200 people by car, bus and bikes. It’s so obvious, but when you see it side by side, it’s impactful. More transit and bike lanes please!

    Parisians don’t eat bouillabaisse. That’s how the cops get you.

      I love bouillabaisse and like saying the word

    This is one of the dumbest ideas – prohibitively expensive to enforce, and practically unenforceable.

      It’s common in many European cities
