Blaise Pascal Invented Fixed-Route Public Transit on His Deathbed
One of the Greatest Inventions in the History of Human Transport
In 1662, dying of illness at 38, Blaise Pascal designed and launched the world's first fixed-route public transport network in Paris. His eight-passenger horse-drawn carriages ran on predictable frequencies along radial and orbital routes, forming a connected network that anticipated every bus, tram, and train. The service was affordable, popular, and overcrowded—a success that proved geometry, not private carriages, could solve the city's mobility problem.
Pascal discerned that fixed routes — and only fixed routes — could solve the geometry problem in a way that could include far more people in the benefits of urban mobility.

> Had this really not been done before? Apparently not on land. Ferries are an ancient idea, both for crossing water bodies and for traveling along them. They are fixed routes, of course, but that’s mostly because the shore is fixed. Pascal’s idea was that even though carriages could go from anywhere to anywhere on Paris’s street network, a special kind of usefulness would arise if they didn’t do that, but instead followed paths that people could remember and plan around.
While not exactly a transit system, there were fixed trade and courier routes before this where the dependability and consistency induced build up and improvements around the route. There were probably even times and places you could hitch a ride on someone's cart or group up with others for safety because of how well the routes were used.

> Frequency ranged from 7.5 minutes to 15 minutes, so these came often enough that people could just go out and wait for them, not worrying about a schedule'
If only most cities could have this today

about ferrys. Douglas Adams let one of his protagonists in Dirk Gently's Holistic Detective Agency postulate that the book of revelations was the product of despair waiting for a ferry

It occurs to me looking at the map that a tourist in modern day Paris would still be well-served by this network.
That thought also made me wonder how central Paris' modern metro system overlays onto this. Here's a quick little visualization: https://stirring-biscotti-a978fa.netlify.app/
If you're traveling to or interested in Paris and its history, I really enjoyed "Parisians: An Adventure History of Paris" by Graham Robb. Has some good, accessible and entertaining history relating to (among other things) the construction of the metro.

Well he'd be proud to see the extend of the fixed routes network in France today : https://cartes.app/?style=transports#6.32/47.811/2.097
Each blue polygon is a network. Zoom to see the lines.
Of course we should do way better, and unify all that with a single ticket and single website for route planning.
