Subway entrance to Bockenheimer Warte located in the city center of Frankfurt, Germany
To a greater or lesser degree, most modern subway diagrams ignore the true geographic locations of lines and stations. Riders need to know which line serves which station, and where to transfer to get there, but actual mileage or accurate compass directions aren’t necessary to navigate the system. A time-scale map agrees, but adds a bit of information that the rider does care about: travel time. Stations are spaced according to travel time between them. (You don’t need to tell me these times are, let’s say,optimistic. They’re based on scheduled travel time from MBTA’s trip planner. Your results will vary.)
This is AWESOME. Click through the photo for the whole explanation :)
Travel times on subway maps - interesting approach, but only really for cities with few subway lines, all going in and out of the city centre.
