Older Road Users: Emerging Trends
  • Publication no: AP-R530-16
  • ISBN: 978-1-925451-39-9
  • Published: 20 October 2016

This report identifies trends in crash involvement amongst older road users (aged 75+).

The project incorporated a literature review; analysis of 10 years of crash data from every jurisdiction in Australia and New Zealand; analysis of three years of detailed hospital injury data for older road users in South Australia; analysis of the contributing factors in older road user crashes examined using the Centre for Automotive Safety Research in-depth investigation method; consultations with representatives of all jurisdictions in Australia and New Zealand; and a summary of relevant sections of road safety strategies in a sample of international jurisdictions.

The report provides policy recommendations and describes crash countermeasures relevant to older road users.
