Re: Running Simulations and Demo Databases

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
