# Hobsons Bay TIRTL Freight Harm Report v0.2

This folder fixes the truck-share display issue from v0.1.

## Correction

Truck share is now calculated as:

`nearest_tirtl_total_trucks / nearest_tirtl_total_vehicles * 100`

The v0.1 report accidentally displayed truck counts in the truck-share column because the detector selected the `trucks` column as the truck-share field.

The truck-rate metrics such as `harm_score_per_million_observed_trucks` were already based on truck counts and remain conceptually valid.

## Public caveat

This is still a first-pass proximity match between heavy-vehicle crash coordinates and nearby TIRTL sites. It is not an engineering safety audit.
