AAA Concluded Flaws In Pedestrian Detection System
The American Automobile Association (AAA) has concluded about pedestrian detection technology that it isn’t as effective as car-makers and regulators have claimed. Several popular systems have been put into the test in a variety of conditions, and results obtained were shocking.
AAA utilized a 2019 Chevrolet Malibu with Front Pedestrian Braking, a 2019 Honda Accord with Honda Sensing, a 2019 Tesla Model 3 with Automatic Emergency Braking, and a 2019 Toyota Camry with Toyota Safety Sense. They chose to examine those four types of sedans due to their popularity.
After the study, they found that the car’s detection system can’t see much better than its drivers after the sun goes down. AAA wrote: “All of systems being evaluated were ineffective at night, which is when 75% of accidents related to pedestrian occurring in the United States.” Though manufacturers have already warned drivers of this limitation in the owner’s manual, so what was the point of pedestrian detection technology created for?
The technology worked best when a pedestrian stepped out in front of a car and with the car travelling at 20 miles/hour in daytime. The system collectively avoided collision 40% of the time, and alleviated the speed of the impact by 4.4 miles/hour. Or you may put it in another way, the car still crashed into the dummy pedestrian in 60% of scenarios, which AAA considered as still at high risk.
According to the study, the system worked less effective when the pedestrian’s size shrinked or when the car’s speed increased. The car, travelling at 20 miles/hour, avoided a collision with a child only 11% of the time, and car’s speed could be reduced automatically by 5.9 miles/hour. None of the cars could avoid an accident (or even slow down) when encountering a pedestrian if making a right turn at 15 miles/hour. There was 89% of chance hitting a child who walked in between the two cars even when cars were travelling at just 20 miles/hour. None of the systems avoided a child running into the road at 30 miles/hour.
AAA encouraged drivers to stay aware of their surroundings at all times and not to rely on pedestrian detection technology, particularly at night. They also recommended that automakers should improve the precision of their collision-avoidance system in low-light conditions. And, if you were a pedestrian or a biker, we suggest you be aware of your surroundings as much as possible. Things you can do such as: wear clothing that makes you visible at night, and avoid walking where drivers are not expecting to find you.
