When riding an escalator
Do you have a habit of standing on your right side?
If you're in a hurry
Will you walk around or even run on an escalator?
Recently
Some netizens suggested Chengdu Metro
Remind and guide passengers
"Walk left and stand right" when riding the escalator
But Chengdu Metro responded
This practice is not encouraged
Netizens suggested that the escalator "go left and stand right"
Chengdu Metro: Not recommended
"Left and right" means that when taking an escalator, the passenger stands on the right side of the escalator and gives way to the left side of the escalator, so that people in a hurry can go first from the left.
Because of the goodwill that reflects the convenience of others, "walking on the left and standing on the right" was once regarded as a habit of civilized courtesy, and many large cities in the world have promoted and advocated it, and thus it has become a certain "weather vane" of the city's developed and civilized degree.
For netizens' suggestions, Chengdu Metro recently replied that the height of each step of the escalator is much higher than that of ordinary walking stairs, and there is a risk of "falling and falling" when walking on the escalator, especially during peak periods, when the flow of people is large, once someone in front falls and the passengers behind cannot avoid it, it may cause a large-scale stampede.
In addition, in the long run, "left and right" will have a certain impact on the escalator, so "left and right" is not advocated. In order to ensure the safety of passengers, passengers are encouraged to remain stationary when riding the escalator.
Studies have shown that when people are "walking on the left and standing on the right", the escalator can carry 81 passengers per minute, and when people stand on both sides at the same time, the escalator can carry 113 passengers per minute. In order to make it easier for a small number of passengers to hurry, more passengers were blocked at the entrance of the escalator. In the long run, it will also cause the escalator to tilt slightly.
In addition, people walking on elevators are more likely to cause elevator accidents, and data shows that about three-quarters of escalator accidents are caused by people walking around.
In many places, the "left-to-right" initiative has been cancelled
In recent years, Beijing, Shanghai, Guangzhou, Nanjing, Hong Kong and many other places have canceled the "left-to-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?
- The step height of the escalator is different from the step height of the staircase, 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 higher than the design height of the stairs in public places 13cm-18cm;
- In addition, according to the regulations, the step depth of the escalator cannot be less than 38cm, which is much higher than the minimum requirement of 22cm for the tread width of ordinary stairs.
- 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".
- From the perspective of the design principle of the escalator, the slope of the escalator is a little higher than the height of the stairs of the daily building mechanism, which is not suitable for walking.
Expert: Just stand firm when you sit on the escalator
Wu Bin, an elevator expert and senior engineer, said that the "left and right" method will produce balance deviations, resulting in a lighter load on the "left" side of the elevator and a heavier load on the right, which will cause tilting.
Therefore, when taking the escalator, you only need to stand firm and hold it up, and passengers who are in a hurry need to pass safely and quickly, the best way is to take the stairs.
