Among the driver assistance systems, the so-called Adas (short for Advanced driver-assistance systems), automatic emergency braking is one of the most widespread: it has been widely offered for the last three or four years and is also standard in many city car. There are various types, which act at city speed or even at high speed. These devices use a front camera and / or radar capable of detecting obstacles, whether they are cars, pedestrians or cyclists, and activate the brakes to slow the car to a stop if the driver does not do it in time, avoiding an accident or limiting the consequences.
Known in English as Autonomous Emergency Braking, abbreviated to AEB, automatic braking is the focus of a study commissioned by the Automobile Club of Italy and Bosch, a German company specializing in car components. With the support of the Filippo Caracciolo Foundation for road safety and the Politecnico di Torino, they cross-referenced a series of data, including information on the nature of accidents in Italy, numbers relating to the models of cars in circulation, and information on distances from from the “black boxes” of 1.5 million vehicles in 2017 and 1.8 million in 2018. LESS ACCIDENTS – Based on this information, the authors of the study narrowed the field of investigation to the role played by automatic braking in accidents from rear-end collision, about one third of those recorded overall in Italy. It emerged that the reduction in rear-end collisions in vehicles less than three years old, those in which AEB is most prevalent, stands at 45%. In addition, some models equipped with automatic braking have been shown to be up to 38% less likely to be involved in a traffic accident than those without one.
These results reinforce the conclusions reached by a 2019 study, with the Adas at the center: a vehicle registered for more than fifteen years, therefore without driver assistance systems, is almost 50% more likely to be involved in a serious accident compared to one registered for only two years. Furthermore, models with more Adas are involved in an accident 5.7 times every million kilometers, while vehicles without them are exposed to a triple risk, being involved in up to 15 accidents every million kilometers traveled.
The European Union has also recognized the importance of ADAS on the road safety front, so much so that, starting from 2022, newly approved cars, vans, trucks and buses have a series of systems as standard. including intelligent speed adaptation, data logging in the event of an accident, warning the driver in the event of drowsiness and distraction, and blood alcohol monitoring. In addition, cars and vans must also be equipped with automatic emergency braking, lane maintenance and systems to reduce the physical consequences of pedestrians and cyclists in the event of an investment.
