It sometimes is convenient to have a small subset of a baseyear that you can use for testing whether the system is behaving appropriately. We have a tool to create such as subset by giving either the city or county name. It's a bit hard coded to the PSRC use, but you can modify it for your application. TODO: Clean up this module so that it isn't hard coded to PSRC.
Use the create_database_subset_by_city_or_county.py module in
urbansim.tools. Fill in input database name near the bottom (for
example, PSRC_2000_baseyear). Edit the values of the
DB_server_setting to be your values. Then execute this module with an
argument that is a city name or a county name. To create a subset of Seattle,
only, use the command:
> python create_database_subset_by_city_or_county.py city seattle
