I had the very same problem. ESRI has a site to get that data and more. If you go to this link:

you should get the data you seek.

Has anyone had problems using the shape files or E00 files for TAZ boundaries available on the Census website? We have noticed that some of our TAZ boundaries look strange, as if there is a problem with collapsing polygons. Do I need to create the TAZ boundaries myself from the TIGER files? Any guidance on this would be greatly appreciated.

Thanks.
