This definitely is great. I'm just sad I haven't gotten my hands on a GPS receiver (still doing research on all this stuff, no real time to use it yet).

How were you able to get the one-ways out of the Tiger data? The best I could see was a guarantee that a road was a two way, but nothing to determine if it was a one way -- the difference between divided, undivided, separated, and unseparated from the Tiger fields (basically whether each direction has a distinct edge in the data or not)
