A university research team published remarkable research results ahead of the deregulation of electric kickboards on the 10th of next month.
This is an analysis of how much you hurt someone when you hit a bicycle or a person walking while riding the'electric wheel'.
The case of'electric kickboard' can also be inferred.
Reporter Han Sang-woo will tell you in detail.

Cyclists are always nervous when personal vehicles such as electric wheels and kickboards approach.
[Hanman-eok/Gwanak-gu, Seoul: I do a U-turn quickly, turn left, turn right, and suddenly stop suddenly. So, I think I need a way to write a hand signal or something.] The
research team at Hongik University assumes that an electric wheel collides with a pedestrian or a bicycle. Estimated the degree of injury.
When a bicycle with an electric wheel running at a speed of 20 km/h hits a stationary bicycle, there is a 69% chance that a cyclist will suffer a compound injury that injures several places at the same time.
In a head-on collision at 15 km/h, the probability of a cyclist getting multiple injuries reached 100%.
Pedestrians are more likely to be seriously injured.
It was found that if the electric wheel hits a pedestrian from the front at 25 km/h, the probability of compound injury reaches 95%, and if it hits from the rear, there is a 100% possibility of compound injury.
Unlike electric wheels, where the wheels dominate, kickboards with handles and iron posts are more dangerous, the researchers say.
[Kim Kyu-Hyun/Hongik University, Professor of Mechanical System Design Engineering: Kickboard has many hard parts, so if you compare it closely, it will be a little more dangerous, so you can expect it.]
After a collision with a personal vehicle, both passengers and pedestrians fall to the floor and head to the ground. You need to wear a helmet as much as it can cause serious injury, and you should consider lowering the speed limit to minimize damage.
