Netizens suggested that the escalator "go left and stand right" Chengdu Metro: it is not advocated
Recently, some netizens suggested Chengdu Metro
Guide passengers with loudspeaker reminders
When riding the escalator, "go left and stand right".

Chengdu Metro responded that the height of each step of the escalator is much higher than that of ordinary walking stairs, and walking on the escalator has the risk of "falling and falling", and may also cause a large area of stampede, so it is recommended that everyone stay still when taking the escalator. If passengers do need it urgently, they can opt for a fast-track staircase.
Netizens have mixed reviews on this matter. ↓↓
Some netizens support the practice of "walking left and standing right".
Some netizens believe that this practice is dangerous.
Some netizens said that they generally choose to take the stairs.
In recent years, Beijing, Shanghai, Guangzhou, Nanjing, Hong Kong and other places have canceled the "left and right" initiative. In 2019, Shanghai Metro also issued the "Latest Version of the Escalator Instructions", canceling the previous advocacy of "walking on the left and standing on the right", and adding "prohibiting walking and running while taking the escalator".
In addition, according to the operation data of Nanjing Metro Operating Company, the long-term "left and right" damage to the elevator is great, and 95% of the elevator damage is caused by the uneven force of the elevator.
Why is it not suitable to move around when riding an escalator?
First of all, let's answer from a scientific point of view, why is it not suitable to walk and run when riding an escalator?
According to the current national standard (GB16899-2011), the step height of the escalator is generally 21cm, and the highest shall not be greater than 24cm, which is 13cm-18cm higher than the design height required by the stairs in public places; In addition, according to the regulations, the step depth of the escalator should not be less than 38cm, which is also far higher than the minimum national requirement of 22cm for the tread width of ordinary stairs.
Therefore, if people walk on the escalator, it is easy to step on the air or trip, and it is easy to squeeze into other passengers on the escalator during the walk, resulting in accidents.
In addition, the speed of the elevator in the mall is generally 0.5 meters per second, while the elevator speed in the subway is a little faster, about 0.65-0.7 meters per second, which belongs to the "high-speed elevator". If someone is in a hurry to go up and down, it is easy to "bring down a large piece" in the event of a fall or emergency.
The escalator has a high slope and is not suitable for walking
Wu Bin, senior engineer of elevator expert: From the design principle of the escalator, it is completely different from the traditional staircase, because the slope of the escalator is a little higher than the height of the staircase of our daily building mechanism structure, which is not suitable for walking.
The "left-to-right" approach is also unreasonable, because it will produce a balance deviation, which will cause the "left" side of the elevator to be relatively lighter, and the right side of the elevator will be a little heavier, which will produce a tilt.
Experts say that when taking the escalator, you only need to stand firm and hold it up, and passengers who are in a hurry, if you want to pass safely and quickly, the best way is to take the stairs.
