RE: Running Simulations and Demo Databases

Himanshu Joshi,

The simulation ran smoothly. As suggested, i placed the fully qualified
variable name in the variable name column of the model specification table.

Thanks to all that help.

Joe

Joe,
 
I just figured out the problem. The problem lies in your
residential_land_share_model_specification and coefficients table. The new
variable names have opus.urbansim.gridcell. before its description. For
example the coefficient_name dev1 has variable name as
opus.urbansim.gridcell.devtype_1 instead of just devtype_1.
I was getting this error too, but after making this change I was able to run
the model for our data successfully.
 
Hope this will help.

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
