This European travel map by Benjamin Td shows how far you can travel in five hours, given the location of the station. Just hover over the map and you’ll see areas or isochrones that can be reached in five hours, assuming 20 minutes to exchange.
The project is based on data from Deutsch Bahn, and was inspired by Juli Tens’ multi-point map. It reminds me of Tom Carden’s (now retired Flash) travel time map from 2008.
I wonder what this would look like for the United States, but I’m also a little scared to know.
