Baltimore gets a radical new transit map (direct PDF link) to go along with its redesigned bus network, which goes into service on Sunday. The map, which Greater Greater Washington reports was designed by Marc Szarkowski, adopts a diagrammatic radial style—essentially, a diagrammatic map based on concentric circles rather than a grid.

For those who find such a map just a little too out there, the Maryland Transit Administration also has a system map with a more familiar design (PDF).

They call it a geographic system map, only it isn’t: it’s still a schematic, just less radical—or, if you like, less radial. [Planetizen]
