I didn't want to spend money on that, so I just used Selenium to simulate what a real user may do.

This whole code is just a big bodge. I just control the web browser with the script, and instruct it to type into the search input coordinates, and scrap the page to retrieve the times.

If you'd like a better way to do this with an API, reach to me in DMs, I'd be happy to help

Unfortunately, I think my code won't help you that much. As I dont have access to any maps API, I basically just used Selenium to simulate inputs as a real user would do. This is time consuming because the whole page has to render, for nothing.

If you don't mind spending a few bucks on a Google Developer account, you may have an easier time achieving your goal using their API.

I'd be happy to help if you need.

A bit of context :

This was done using Python. The algorithm works by asking Google Maps what is the fastest route using public transports from any point to Notre-Dame, on 02/20/2023 at 4PM.

Changes from a subway line to another are allowed, as well as walking or taking the bus.

EDIT : Also, Notre-Dame as been chosen because it is roughtly at the center of Paris, and the starting point of all distance measurements in France
