Driver monitoring technology could prevent thousands of serious road injuries
New research from the Monash University Accident Research Centre (MUARC) has found that camera-based Driver Monitoring Systems (DMS) linked to Advanced Driver Assistance Systems (ADAS) already fitted to vehicles could prevent or mitigate nearly 40,000 serious injury crashes in Victoria alone over the next 30 years, and that doing so would be highly cost-effective.
These findings were presented at the prestigious 28th Enhanced Safety of Vehicles (ESV) conference co-hosted by Transport Canada and the United States National Highway Traffic Safety Administration, held in Toronto earlier this month.
The paper, led by MUARC's Associate Professor Michael Fitzharris, examined the proportion of serious injury crashes in which driver distraction and drowsiness were direct contributing factors. It then estimated the likely financial benefits of implementing DMS technology as required under the EuroNCAP Driver Engagement Protocol, which came into effect on 1 January 2026.
Findings from MUARC's Enhanced Crash Investigation Study showed driver distraction and drowsy driving together contributed to around 40 per cent of hospitalisation crashes, pointing to a significant opportunity to reduce serious injury crashes. Once alcohol and drug impairment, mobile phone use, and sudden medical events were also considered, more than half of all serious injury crashes involved at least one of the risk factors targeted by the EuroNCAP Driver Engagement Protocol.
Under the EuroNCAP Protocol, vehicles must be fitted with a driver-facing camera system that continuously monitors driver state. When distraction or drowsiness is detected, the system warns the driver and automatically increases the sensitivity of forward collision and lane-keeping systems. If the driver is unresponsive, the vehicle can assume control and bring itself to a safe stop.
The analysis found that ‘flipping the fleet’ and fitting DMS to the full Victorian passenger and light commercial vehicle fleet would deliver a benefit-cost ratio of 2.82, meaning that for every dollar spent, almost three dollars in avoided trauma costs would be returned. Over a 30-year implementation period, as DMS-equipped vehicles progressively replace older ones, the benefit-cost ratio rises to 21.8, with an estimated AUD $13 billion in savings against an implementation cost of around AUD $0.6 billion.
Associate Professor Michael Fitzharris said the findings make a compelling case for the rapid adoption of driver monitoring technology.
"Distraction and drowsiness are persistent and significant problems, being contributing factors to four in ten serious injury crashes," Associate Professor Fitzharris said.
"What this analysis shows is that the technology required under the EuroNCAP Protocol is not only effective in addressing these behaviours, it is overwhelmingly cost-effective. Even under conservative assumptions about effectiveness and higher implementation costs, the benefits far outweigh the costs."
