Two rapidly developing technology areas, Cooperative Intelligent transport systems (C-ITS) and Automated Driving (AD) applications, are reputed to have a substantial impact on road trauma through the increased use of technology both to assist drivers with the driving task, as well as providing enhanced crash avoidance capabilities. This project aimed to identify emerging C-ITS and AD applications and assess their potential safety benefits for Australia and New Zealand.

A comprehensive literature review and expert consultation found that C-ITS and AD were predicted to have significant potential to reduce road crash risk and injury consequences, with estimates varying widely between studies.

Using an analysis of Australian serious injury real-world crashes, expert estimates were made of the potential effectiveness of the following light passenger vehicle applications, as well as estimates of the annual savings in serious injuries Australia and New Zealand-wide.

Despite the clear potential benefits, several limitations were found that will need to be addressed before widespread implementation becomes possible.
