UrbanSim 3 vs. 4

Hi,

I'm working on a research project for TxDOT looking at what type of land
use model is best for each type of region (defined by size, resources,
need, ...) depending on a variety of factors. I had been trying to get
UrbanSim 4 running for awhile and was having some of the same problems
as Zachary, so I just this week switched to UrbanSim 3.
Although there are many advantages to UrbanSim 4 (as listed
http://www.urbansim.org/news/index.shtml#opus), we're worried that there
are still some bugs in the code and the documentation has not yet been
ironed out. Also, it is very helpful to have the Eugene test database
running for the earlier version. As we're looking for general
conclusions about types of models, we feel this should suffice. My only
concern is that the Java version is no longer being maintained, so if we
do have a problem it may be more difficult to get it resolved.

I just wanted to see if anyone on this list had any convincing arguments
as to why we shouldn't use the Java version for our research...

Thanks!
