I grabbed the road data from http://www.maproom.psu.edu/dcw/ and converted it to a list of points, which I could read into Asymptote (the procedural drawing program I use) directly. If you're using Illustrator, Inkscape, or something similar, you could probably do the same thing with SVG; that is, convert the ARCInfo polylines, which look like this:
Code:
7.7930138E+01 1.8470718E+01 7.7917450E+01 1.8458904E+01
7.7914314E+01 1.8458422E+01 7.7908096E+01 1.8452629E+01
7.7904953E+01 1.8453297E+01 7.7896950E+01 1.8460600E+01
7.7887535E+01 1.8461683E+01 7.7878410E+01 1.8457710E+01
into SVG polylines:
Code:
<polyline points="7.7930138E+01,1.8470718E+01 7.7917450E+01,1.8458904E+01
7.7914314E+01,1.8458422E+01 7.7908096E+01,1.8452629E+01
7.7904953E+01,1.8453297E+01 7.7896950E+01,1.8460600E+01
7.7887535E+01,1.8461683E+01 7.7878410E+01,1.8457710E+01"/>
which you can open as vector data.
