Module calibration 

Scientific calibration helpers for pedestrian fundamental diagrams.

The microscopic models in this crate keep their literature defaults in their own Params structs. This module provides an explicit calibration layer for deployments that need a published speed-density envelope, starting with Weidmann’s 1993 indoor-corridor fundamental diagram.

Structs

CalibrationPoint

A density/speed observation used by calibration reports.

CalibrationReport

Error summary against a reference fundamental diagram.

WeidmannCurve

One empirical speed-density reference curve.

Functions

apply_weidmann_speed_cap

Clamp every pedestrian velocity to the Weidmann speed at density.

apply_weidmann_speed_target

Set every pedestrian velocity to the Weidmann speed at density.

density_for_area

Density implied by count pedestrians over area_m2 square metres.

mean_speed

Mean scalar speed of the supplied pedestrians.
