At the end of the holiday, many people are going to commute to work in a busy crowd. Have you found out why you can't walk fast in a crowded crowd? Even on an one-way street, there is always someone in front to slow down the whole team, not to mention the two-way flow of people coming and going.

Who is slowing down the pace of progress? Researchers have used scientific methods to find out the "culprits" that affect traffic.

Who is slowing down the pace of walking? | Pixabay in an experiment, researchers recruited 27 people to simulate the scene of walking in both directions on the road. One group of people (red hats) walked intently on the road, while in the other group (yellow hats), the researchers placed three people walking while playing with their mobile phones.

In order to investigate more carefully, the researchers also assigned the three mobile phone players to the front, middle and back of the team to observe their impact on the whole team.

Does playing with your cell phone really affect crossing the road? | reference [1] generally speaking, when we walk on the road and see oncoming crowds, we will consciously predict their direction and position through TA's eyes and behavior, actively look for channels and avoid collisions with others.

This synchronous group behavior seems simple, but it contains a lot of knowledge. For example, flocks of birds and fish will be arranged in various formations, so that they can not only keep up with the team, but also ensure that they do not collide with others.

In short, whether in the human group or in the animal society, we or animals will always spontaneously do some behavior to maintain the order of the whole group. In other words, as long as you walk honestly on the road, you can improve traffic efficiency.

In the experiment, we can also see that even if people walk toward each other, they will spontaneously split into two teams and cross the road quickly.

The Red Hat and Yellow Hat groups formed a clear queue and quickly crossed the road. | reference [1] but after the installation of "people who play with mobile phones", the situation becomes less optimistic.

You can see that in the video, when the mobile phone player stood at the front of the line, the pace of both teams slowed down significantly. The whole team with yellow hats had to slow down because it was difficult to avoid obstacles.

And the red hat team opposite has also been greatly affected. Because the mobile phone player bows his head, the direction of progress is unpredictable. To make matters worse, oncoming pedestrians need to slow down or turn to try to avoid the inattentive passer-by.

Mobile phones can distract us and make it difficult for us to predict the pace of the people around us. Studies have shown that if you stare at your phone while walking, your original wide field of vision will be reduced to between 1 and 10 degrees. Make you completely unaware of what's going on around you.

The study shows that walking and playing with mobile phones is not only harmful to you, but also disturbs a whole group of people.

Of course, this experiment only simulates the simplest scenario of crossing the road without a car. The situation on the road is often much more complicated, we have to move forward in the traffic, but also in the crowd up and down the stairs or in and out of the subway, and at this time, playing with the mobile phone affects more than just speed.

Stop playing | Weibo screenshot while looking at the phone while walking, not only affect the speed, affect the field of vision. And when you think you're walking in a straight line, you've already missed!
