The increasingly popular lane keeping assist (LKA) and lane departure warning (LDW) systems offer a “statistically significant” reduction in traffic, according to a report from a leading Australian research body. with road injuries.
The highly regarded Monash University Accident Research Center (MUARC) in Melbourne has found the installation of such systems is associated with an estimated 22% reduction in crashes resulting in death or serious injury. critical, often occurring in high-speed areas.
This is because unintentional lane departures at high speeds account for an overwhelming proportion of serious light vehicle crashes, accounting for 42% of fatal crashes and 55% of all deaths.
The often-cited accident research agency says its new study – billed as Australia’s first – is designed to calculate the benefits that could be derived if LKA and LDW were required for an accident. with all new light vehicles entering Australia.
The results show that in this hypothesis, you can expect the total number of collision accidents in Australia to drop to 884 per year using current numbers, of which 76 are fatal. and 517 cases of serious injury.
MUARC said how and when the hypothetical scenario of fully equipping the fleet with LKA could be achieved is not within the scope of the study.
MUARC adds: “These estimates can be conservative as not all model variants identified as equipped with LKA in the analysis are actually equipped with this technology,” MUARC added. adds, and recommends that further assessments be performed after accumulating more real-world data.
“…Technologies that reduce unintentional lane departures are vital in Australia’s road safety landscape, particularly on high-speed country roads,” it added.
This project is funded as a contract study by the Victorian Government Department for Transport and focuses on light vehicles with a gross vehicle weight of less than 3.5 tonnes.
The dataset includes statistics on police-reported accidents from Queensland, New South Wales, Victoria, South Australia and Western Australia for the years 2013 to 2019, which is considered nationally representative.
The make and model of the vehicles recorded in the crash data were determined using the VIN decoding procedure while the LDW and LKA equipment were determined using the specification data. media specifications provided by RedBook.

About 60% of new vehicles will be equipped with this technology as standard or optionally by 2020, but the total breakdown rate that year is equipped with some type of LKA is more than 12%.
The process of estimating potential benefits includes the following steps:
- Definition and tabulation for light vehicles population in accidents considered susceptible to mitigation or avoidance by LKA or LDW
- Identify and tabulate light-sensitive vehicle injuries accident
- Determine the proportion of sensitive collisions in the entire collision population
- Determination of injury rates by severity (including fatalities) in sensitive crashes in the entire crash injury population
- Collision estimation and LKA-related injury reduction impact in light vehicles
- Calculate accident or injury benefit rates for all police-reported crashes
