Hi Kurt,
If you use Mapserver with PostgreSQL/PostGIS, this might
help you:

I didn't try Tiger data for routing yet, but it should be
possible.
Of course you need to adjust your data and create a road
network topology.

Dear list,
Here may not be the right place to post this question. However, I
understand that mapserver users come from different fields. There must
be some experts who are able to give me some advices. Thanks in advance.
My question is how to use tiger file for routing purpose. As my
understanding, routing needs the length of every line between source and
target nodes. It seems that the tiger file does not have this
information. I really appreciate if someone can provide some advices,
tips, or references in order to achieve this matter. Thanks again.
Best,
Kurt
