class polaris.analyze.result_kpis.ResultKPIs(inputs: PolarisInputs, cache_dir: Path, population_scale_factor: float)#

Bases: object

This class provides an easy way to extract relevant metrics for a single simulation run of POLARIS. The easiest way to generate an instance is via the factory method from_iteration which takes the path to the outputs of a simulation run (or a ConvergenceIteration())

from polaris.analyze.result_kpi import ResultKPIs

kpis = ResultKPIs.from_iteration(ref_project_dir / f"{city}_iteration_2")

Metric comparison plots can then be generated in a notebook using:

results = KpiComparator()
results.add_run(kpis, 'an-arbitrary-label')
results.plot_mode_share()
results.plot_vmt()
results.plot_vmt_by_link_type()

Any number of runs can be added using add_run up to the limit of readability on the generated plots.
