A recent study by the American Traffic Safety Agency (AAA) showed that advanced systems to help drivers will make many car and vehicle leaders around the world bad drivers, their skills and abilities to drive over time will be eroded, not paying attention to the road, and preoccupied with secondary side matters While driving, they let drowsiness slip into their eyes, which may result in errors and accidents, and dent traffic safety on roads.

AAA reported that the study, conducted in cooperation with the Virginia Institute of Transport Technology, targeted 120 drivers for more than a year, in order to understand the effects that semi-automatic driving systems have on the skills and behavior of drivers and drivers while driving.

The study sample

In a report published by the study on its website recently, the Foundation stated that the study sample was divided into two groups, the first for drivers driving in a natural, non-motorized manner, but with advanced driving systems in their cars, whether active or inactive, while the second group included drivers who drive Under driving conditions, low, medium, or full-level, they rely on two basic systems of advanced driver assistance systems known as ADAS, which are the ACC Adaptive Cruise Control system, which assists the driver in steering the vehicle, especially at curves and crossing intersections. And others, in addition to n Or to help keep the car inside track «L K er», which is driving the car to the final station at the end of the journey, and makes them into a safe path all the way.

Implementation

The Foundation indicated that to carry out the study, the vehicles participating in the test were equipped with a data acquisition system, which relies on video cameras and vehicle sensors to collect data related to the driver and driving continuously, and during a period that lasted more than a year tens of hundreds of video clips and other data that documented behavior were taken Drivers while driving, where kinetic algorithms were used to identify potential critical safety events, while trained data specialists used video and kinematics to illustrate factors on the driver, vehicle and environment.

She added that the remote view locations that drivers look at while driving, such as off-road sites, whether related to driving or not related to driving for the purposes of the analysis, were also classified, as was the analysis and evaluation of drowsiness periods, through analyzes of videos captured on the face of the driver, to determine the percentage of time The eyes are closed.

Results

The study concluded that the concurrent use of the ACC systems for adaptive cruise and the LCA system to maintain the vehicle's path by the group of drivers who drive naturally, was associated with a 50% increase in the likelihood of drivers engaging in forms of secondary activities and behaviors Not related to driving, such as looking outside the car, tampering with mobile phones, or talking to the person with them, compared to drivers who do not use any of the two systems. But the matter is a little different for drivers from the second group, whose cars operate with fully automatic driving systems or Intermediate, where analyzes and follow-up showed that they were more likely to engage in secondary things and get their eyes out of the wheel, but they did not, which indicates a lack of confidence in automated systems so completely.

Speed ​​errors

The study noted the existence of behaviors that can be classified as "unsafe behaviors" in the natural driving group, as these behaviors embodied that the performance errors related to speed reached 11% in the data samples that were documented for drivers in the absence of the two "ACC" systems And "LKA", but these errors increased to 19% when the two systems were in operation, while when operating each system separately, speed errors reached 16%.

Drowsiness while driving

The study revealed that the prevalence of drowsiness and a tendency to sleep while driving was low in the normal driving group, as it appeared in only 0.6% of cases, but the second group of motorists operating in advanced automated assistance systems, in which sleepiness and a tendency to sleep increased to 5.4% of cases.

AA

The AAA Traffic Safety Education and Research Foundation was founded in 1947. It is a not-for-profit organization that is supported and supported by the US government, and is dedicated to saving lives by preventing traffic accidents and reducing injuries when they occur, by conducting research on their causes and educating the public about accident prevention strategies and reducing Injuries when they occur.
