UrbanSim Database Tables

Note: This section does not yet represent UrbanSim 4.

This chapter describes what UrbanSim needs in its baseyear database, ways in which the baseyear may be structured, how to create a set of scenario databases that share much of their data, and the use of output databases.

UrbanSim currently uses three types of databases, each of which is described in more details in following sections:

baseyear database

- defining the initial state of a simulation in a particular base year.

scenario database

- defining changes to a baseyear (or another scenario) database.

output database

- optional repository for simulation results.

Most database tables are optional. The required set of tables is determined by the variables used by the models. This can be found by looking at the models' specification tables.
