Hello Aaran,
Unfortunately, we do not yet have permission to distribute a working
UrbanSim4 sample database. The database we used for the workshop was
allowed for the workshop, but we do not yet have permission to
distribute it globally. This is high on our list, but we need to get
more approvals before this will come to pass. You can be assured that
when we do get permission, we will announce it on our email distribution
lists.
We have collected the list of steps needed to convert an UrbanSim 3
database into the format for UrbanSim 4 and plan to put these into the
manual in the next week or so (I left them in Seattle, so it will have
to await my return on Friday...).

David,
Is there a working updated UrbanSIm 4 sample database? I assume
that you would have used one for the workshop students? If we could get
UrbanSim 4 simulations to run as easily as we did with UrbanSim 3 then
the remaining issues may be easier to solve. A sample base year data
set seems to be the missing piece of the puzzle.

Joe,
The database section of the manual does not yet conform
to the UrbanSim 4 standards. It is very close, but different in several
ways.
One of these ways is models_variables - this table is no
longer used in UrbanSim 4. UrbanSim 4's integrated estimation process
uses a Python file (for instance, see
opus.psrc.estimation.estimation_HLCM_variables.py) to specify the set of
model variables to use. The estimation process then creates
coefficients and specification objects, which may be stored as tables in
the database, so that a later simulation can re-create the coefficient
and specification objects.
We plan to add a tutorial on estimation, hopefully
within the next few weeks.

Liming,
Thanks for your help, you have certainly pointed
me in the right direction.
Reading through the user manual, the LPM model
requires that its variables must be present in the model_variables. I am
using an old model_variables table with the JAVA CLASS column still
pointing to java paths not to OPUS. I have tried tinkering with this
table changing path names and column names but to no avail, i will
continue reading through the code to better understand how everything is
pased from the db.
That being said, Does anyone have the table
schema for URBANSIM4 model_variables table??, ( in the user guide it
merely refers to it).
if not, I will patiently await for documentation
of the Database tables section (Chapter 8) to be completed.
Until then.....Hope you guys had a successful
workshop.
Best Regards,
Joe

Joe,
The error with land price model is
because of a change of variable name format in model specification. You
can refer to the user guide sections of variable name and specification
and coefficients for the new format. We'll also provide some documents
on converting from UrbanSim3 to UrbanSim4 soon. For OpenEV you'll need
to prepare a prototype_dataset and template OpenEV project file
beforehand. It works for the application of PSRC in our environment with
some file locations and names hard-coded. Because of compatibility
issue, we may eventually phase it out and it won't be supported.
Hope these help.
Liming.

Hi all,
I have been exploring Urbansim 4. I have
just encountered problems with running a simulation and creating
indicators for the Eugene_Springfield baseyear 1980. I think this is
attributed to that it was made for Ubransim 3 as the Input Database. Is
there a sample database for Urbansim 4 (PSRC perhaps)?
1. If there isn't, I have started simple
with just simulating the "land price model". I started a simulation but
the following error: "No variable ('gridcell.devtype_1'). Looking
through the opus.urbansim.gridcell , I have found only devtype_DDD . I
do not know how/where this variable is computed from. (I assume devtype
is Development Type)
2. In creating an Openev_map, do you
need to save a opf file beforehand with all the shapefiles loaded within
it? I recieve the following errors: unable to load
'template_region_uga_leg.opf' and get an empty tif file. I have tried
opening the Shapefiles for the Eugene_Springfield in Openev but it just
crashes the program. (I am on WinXP using Openev_FW)
Any advice and comments are greatly
appreciated.
best regrads,
Joe
