Scheduled Employment Events Model (SEEM)

Objective

The Scheduled Employment Events Model (SEEM) handles employment events (projects) that are scheduled to happen in specified simulation years.

Algorithm

It modifies the jobs table according to specified action of each events in the scheduled_employment_events table. See the sample scheduled_employment_events table below for actions that are supported.

Configuration

OPUS path to model code

urbansim.models.scheduled_events_model

Model Parameters

The configuration of the SEEM in the zone model system is summarized in the following table:

Element	Setting
Dataset	Jobs
Model Type	User specified, rule-based

Data

scheduled_employment_events table is used by the Scheduled Employment Events Model. Below is a sample scheduled_employment_events table that demonstrates the functions of scheduled_employment_events_model. The optional notes column explains what each event does. Column year, action, attribute, and amount is required; users can remove one or all columns sector_id, zone_id,building_type_id or add extra columns that are primary or computed attributes of job dataset.

year	action	attribute	amount	sector_id	zone_id	building_type_id	building_id	__notes__
2010	add	not_used	5000	4	100	-1	-1	add 5000 jobs of sector 4 to zone 100
2010	remove	not_used	1000	3	-1	-1	1001	remove 1000 jobs of sector 3 with building_id equal to 1001
2011	set_value	building_id	1011	3	-1	-1	1001	relocate all sector 3 jobs from building_id 1001 to 1011
2011	target	not_used	3000	5	-1	-1	1002	set number of sector 5 jobs in building 1002 to 3000 (add or remove jobs to meet the target)
