70 pages?? It takes only one sentence to say zone boundaries need to be
based on access to the network being modeled, period.

The Florida DOT has just posted a 70 page report discussing TAZs and
their construction. While the information is for the model users
community in Florida there is a wealth of information in the report that
those who think about such things will find of interest. The document
is well worth adding to any list of TAZs references that you may have.
The report can be found on the Florida Transportation Modeling web site
