Creators

The model can be created using pre-defined creators in urbansim. They set useful default values for arguments of the AgentLocationChoiceModel constructor, run_config and estimate_config, depending on what model they create. In a production run we use one creator, namely the HouseholdLocationChoiceModelCreator. It uses all default values of the LocationChoiceModel constructor and sets run_config to:

{   "compute_capacity_flag": True,
    "sample_size_locations": 30,
    "correct_sampling_bias": False,
    "capacity_string": "vacant_residential_units",
    "number_of_agents_string": "number_of_households",
    "number_of_units_string": "residential_units"  }

Entries of estimate_config are set as to:

{   "estimation": "opus_core.bhhh_mnl_estimation",
    "sample_size_locations": 30,
    "estimation_size_agents": 1.0,
    "correct_sampling_bias": False,
    "weights_for_estimation_string": "residential_units" }
