# video | Do pedestrian detection systems help avoid accidents?

Statistics show that in 2017 cars5 977 pedestrians were shot down, whereas in 2009 this figure was much lower - about 4 109 incidents were recorded. To reduce the number of accidents, car manufacturers equip them with pedestrian detection systems, which, when people suddenly appear on the road, automatically activate the brakes. Researchers at the Insurance Institute for Road Safety (IIHS) decided to test the effectiveness of these systems by conducting a very intense test, which was filmed on video.

Pedestrian recognition systems are in models withautomatic driving function. For continuous scanning of the road for pedestrians, two sets of sensors are used: cameras installed on the rear-view mirror and sensors on the front grille. A special algorithm determines whether the object in front is a pedestrian and assesses the risk of a collision - if it is high, the system applies the brake at a higher speed than the human response.

According to the IIHS Active Testing ManagerDavid Ailor’s safety, reduced man’s response to sudden pedestrians is associated with low concentration. Car software has no distractions, so it will respond much faster anyway.

To verify this, the institute conducted a test involving 11 SUVs with a braking function in the event of pedestrians. Within its framework, researchers recreated several dangerous scenarios.

The three most common situations where a car knocks a person:

  • adult, facing the street on the right side;
  • a child running out on the street because of two parked cars;
  • adult, walking back to the road, turning away from the movement.

The study showed quite soothingresults. Four SUVs showed instant response to pedestrians: Honda CR-V, Subaru Forester, Toyota RAV4 and Volvo XC40. Five models slightly touched pedestrians, but still they would hardly have caused serious damage: Chevrolet Equinox, Hyundai Kona, Kia Sportage, Mazda CX-5 and Nissan Rogue. The worst results were shown by Mitsubishi Outlander and BMW X1 - it’s better not to rely on their braking system.
