Overview

The models to execute when running UrbanSim are determined by the configuration (see Section ). Its entry ``models'' is a list of character strings that identify the models to run in that order. UrbanSim defines following models:

``land_price_model''

- activates the LandPriceModel which predicts residential and non-residential land value (see Section 7.4.2).

``development_project_transition_model''

- activates the DevelopmentProjectTransitionModel which creates projects of different types for development (see Section 7.4.3).

``residential_development_project_location_choice_model''

- activates the
DevelopmentProjectLocationChoiceModel for residential projects only. It places the newly created projects of residential type into locations (see Section 7.4.5).

``commercial_development_project_location_choice_model''

- activates the
DevelopmentProjectLocationChoiceModel for commercial projects only. It places the newly created projects of commercial type into locations (see Section 7.4.5).

``industrial_development_project_location_choice_model''

- activates the
DevelopmentProjectLocationChoiceModel for industrial projects only. It places the newly created projects of industrial type into locations (see Section 7.4.5).

``development_event_transition_model''

- activates the DevelopmentEventTransitionModel which creates development events from given projects (see Section 7.4.6) and the EventsCoordinator which processes the actual annual development (see Section 7.4.7).

``residential_land_share_model''

- activates the ResidentialLandShareModel which predicts the fraction of residential land (see Section 7.4.8).

``household_transition_model''

- activates the HouseholdTransitionModel which simulates deaths and births in the population of households (see Section 7.4.9).

``employment_transition_model''

- activates the EmploymentTransitionModel which simulates creation and loss of jobs (see Section 7.4.10).

``household_relocation_model''

- activates the AgentRelocationModel where agents are set to be households. It determines which households will move to another locations in the simulated year (see Section 7.4.11).

``household_location_choice_model''

- activates the AgentLocationChoiceModel where agents are set to be households. It places moving households to another locations (see Section 7.4.12).

``employment_relocation_model''

- activates the AgentRelocationModel where agents are set to be jobs. It determines which jobs will be moved to another locations in the simulated year (see Section 7.4.11).

``employment_location_choice_model''

- activates the AgentLocationChoiceModelMember where agents are set to those types of jobs that are contained in the table job_building_types. For each type, it places moving jobs to another locations (see Section 7.4.14). An exception is the type 'governmental' for which the ScalingJobsModel is activated (see Section 7.4.15).

``distribute_unplaced_jobs_model''

- activates the DistributeUnplacedJobsModel which places all non-placed jobs randomly to another locations (see Section 7.4.16).
