SACSIM land use inputs are the primary data source for households and jobs on each parcel. While SACSIM does not require land use input updates to run, users may wish to make their own adjustments to land use and population to test alternative scenarios. To aid users in making these adjustments, SACOG staff have provided multiple processing tools and documentation to help users assemble SACSIM’s parcel-point land use and population inputs. Assembly of additional land use inputs such as school employment and enrollments, street pattern, off-street parking supply and cost, and transit proximity are also described in the resources below.

SACOG also provides python scripts for land use input processing. These scripts are available on SACOG’s GitHub.
