Vehicle Mix Analysis

Overview

This page will describe how vehicle types and vehicle mix relate to traffic exposure and collision severity.

Note

Placeholder page.

Planned Content

  • Vehicle-type breakdown from STATS19.
  • HGV and long-vehicle exposure from traffic data.
  • Severity patterns by vehicle mix.
  • Planned Stage 1c vehicle-mix modelling.
