Street map data for a specific region can be extracted from larger OSM
extracts using Osmosis. I usually get my large regional extracts from
http://download.geofabrik.de/.
You will find pre-extracted data for various metropolitan areas at
http://metro.teczno.com/
In your case, you want the link titled "18 MB binary PBF OSM data" at
http://metro.teczno.com/#atlanta .
Once you have the files there you can just change the file names in the
configuration XML when you build the graph.
