Meeting road safety targets will be assisted by the deployment of a range of Intelligent Transport Systems (ITS) technologies which are already available or which will become available over the next few years. A recent Austroads study involved a review of infrastructure-based safety related ITS. This project takes this work a step further by estimating the potential crash avoidance and injury reduction benefits of different types of ITS for Australia and New Zealand, including in-vehicle ITS. This document is the first step in this process. It is a literature review which focuses on the crash reduction effects of different types of ITS. Then the crash reduction benefits which can be expected from the different technologies in Australia and New Zealand are estimated by applying the crash reduction factors identified to the crash database collated for Austroads. This database contains up-to-date records of crashes in all member jurisdictions. These crash reduction benefits are then used to conduct an economic analysis of the different technologies in the context of Australia and New Zealand.
