RE: Running Simulations and Demo Databases

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.

Subject: Running Simulations and Demo Databases

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
