If you like, take really free data instead [1]:
-> Download book datasets 
   -> "OSGeo sample dataset for research, development and education"
       nc_spm_05_2007_0509.tar.gz: North Carolina (NC)
                           State Plane metric LOCATION

It contains two street networks: one is detailed, one is
less detailed. Additionally bus routes, also hospitals,
firestations, schools and further point maps, see
   -> Data set list of maps

We plan to update the data set the next week for
additional maps and a few fixes.
