Vehicle Mix Analysis for Open Road Risk

Placeholder page for analysing how vehicle types and traffic composition relate to exposure, collision risk, and severity.

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.
