Parameters:

trip_length_distribution_path (Annotated[Path, PathType(path_type=file)])
cost_function (Literal['log_normal', 'tanner'])
cost_function_params (tuple[float, float] | dict[int | str, tuple[float, float]])
calibrate (bool)
cat_zone_correspondence_path (Annotated[Path, PathType(path_type=file)] | None)
furness_jacobian (bool)

cat_zone_correspondence_path: Annotated[Path, PathType(path_type=file)] | None = None#: Correspondence between the categories in the TLD and the model zones.

furness_jacobian: bool = True#: Whether to Furness the Jacobian matrix in the gravity model. Find your nearest demand modelling expert for more information.
