Benjamin Tran Dinh’s interactive isochrone map of Europe showing how far you can go by train in five hours (previously) has a new variant that does the same thing for 1911 France. Getting closer in time and place to those original isochrone maps. [Maps Mania]

How Far Can You Go in Five Hours? Or on a Single Train?
Benjamin Tran Dinh (previously) has built an interactive isochrone map of Europe that shows you how far you can go by train from a given station in five hours (assuming a connection time of 20 minutes, which is an approximation: generous if same-station, less so if you have to cross the city). The map updates as you move the pointer across it, which is a lot of fun.
The isochrones are generated from data from the direct.bahn.guru site, a site that is worth looking at in and of itself: it shows all the direct connections from a given station, i.e., everywhere you can get to on a single train. That site, in turn, gets its data from the Deutsche Bahn via a legacy API that is necessarily incomplete and only covers destinations reachable from Germany. But there are no complete datasets of European transport routes, so this’ll do. [Maps Mania]
Travel Times in Helsinki
Lauri Vanhala wanted to figure out the best place to buy an apartment in Helsinki, so he built an interactive sort-of-isochrone map of the city. He explains: “I calculated the travel time from every address to every other address in Helsinki around 7:30-8:00am (about 30 billion searches total!). Then I calculated the (weighted) average travel time to anywhere in the city, using amount of jobs in the target area as weight.” [OSM]
1882 Isochrone Map of France
I think I'm in love: a stunning isochrone map of travel times from Paris by rail in 1882 (making this a very early example of the genre). pic.twitter.com/gaSEzGCQWI

Cameron Booth (of Transit Maps fame) posted an 1882 isochrone map of France showing travel times from Paris by rail to Twitter and boy did it ever go viral. He’s planning on selling a print of it on his online store.
Road Trees
The Road Trees project has produced animated isochrone maps showing road networks erupting fractally from a single departure point.
An isochrone in a map shows with the same color all points from which it takes the same time to arrive to a specific location.
We chose 10 locations around the world and for each of them constructed the isochrones on top of the road network of the corresponding country. Consequently, we plot these isochrones using a dynamic color palette representing the diffusion from the location of interest to any other point of the road network.
Unexpectedly, we found that the isochrones follow beautiful fractal patterns, very similar to networks shaped in the Nature by rivers, veins, or lightnings.
