Lane-keeping and Collision Detection reduce crash risk by more than 30 percent

Most ADAS (driver assistance systems) can significantly reduce the risk of an accident. This is according to new research by the Data Analytics Centre (DAC) of the Dutch Association of Insurers. This confirms the results of a previous study. This time, a much larger dataset was used. Two systems stand out: Lane Keep Assist and Collision Detection. These systems, which warn the driver and/or can intervene immediately if you accidentally leave the lane or before an impending collision, can reduce the risk of an accident by 30 to 40 percent.

Not only is the broader dataset new, but the mutual correlation between systems and the effect in bad weather conditions has also been examined. This also yields interesting results. ADAS still helps in bad weather, but that's not the case for all systems and the effect is slightly smaller. The big positive outlier is Driver Monitoring. This system, which warns you if you are no longer alert enough, can sometimes be a life saver here: the chance of an accident is then almost twice as small. The study also shows that some systems may increase the risk of an accident. This is the case, for example, with (Adaptive) Cruise Control. In bad weather conditions, this effect is even stronger. Further research, for example into the system itself or when and how these systems are used, can provide more insight here.

Geeke Feiter, director of the Dutch Association of Insurers: "The results show that these systems make an important contribution to road safety, if used safely. And that is desperately needed, because the casualty figures, which last year resulted in 745 deaths and 134,000 injuries, are worrying. Let's focus on the further development and good understanding of these systems among motorists." Ward Koopmans, chairman of the ADAS alliance: "The ADAS alliance is pleased with this relevant research into ADAS by the Dutch Association of Insurers. The research shows that ADAS make an important contribution to road safety. Recently, the ADAS covenant was renewed. The cooperating parties in the alliance have agreed to jointly further stimulate safe use. The results of the study offer many tools for the alliance to take the next steps."

For the study Advanced Driver Assistance Systems (ADAS): Road Safety and CO2 Emissions , a unique dataset was used, consisting of accident data from insurers, data from the Road Traffic Department (RDW) and ADAS data, collected by Solera. The dataset consists of more than 690,000 private passenger cars, over the period 2015 to 2022.
