Is the statement of left line and right line correct?

The meaning of "walking left and standing right": "walking left and standing right" is a kind of behavior etiquette that advocates civilized travel and improves traffic efficiency during peak hours. "Walk left and stand right" is neither a safety standard nor an international practice.

The content of "walk left and stand right" means that when taking the escalator, passengers stand on the right, leaving a left position to leave a passage for people who are in a hurry. Keep to the left during rush hours to speed up traffic and improve efficiency.

Scholars question

In 2006, Su Tingbi, an assistant professor in the Department of Architecture of the City University of Hong Kong and a scientific consultant of the Hong Kong International Association of Elevator Engineers, wrote that "walking left and standing right" is actually a trap, leaving a passage to encourage passengers to walk on the elevator, which makes people ignore that walking on the escalator is also a high-risk behavior. He analyzed that in fact, the escalator will suddenly slow down because of unstable voltage, and catching small garbage or cigarette butts will also cause the elevator to suddenly stop. If passengers are walking, it is easy to lose their balance. Su Tingbi also said that passengers walking on the escalator can only save a few seconds, which is not helpful to increase the passenger capacity of the elevator, because if there are two people in each elevator station, the density can be higher, but passengers should keep a large distance when walking. Moreover, walking left and standing right will lead to uneven load bearing on the left and right of the steps and accelerate the loss of parts.

Official query

"Walk left and stand right": After the Beijing accident, Zhang Lexiang, deputy secretary-general of China Elevator Association, pointed out that the biggest misunderstanding of the public riding the escalator at present is "walk left and stand right". This is because the steps on the escalator are not ergonomically designed and it is unsafe to walk on the escalator. Therefore, Zhang Lexiang suggested that passengers should hold the handle, stand well and try not to walk when taking the escalator.

Potential security risks

"Walk left and stand right" focuses on improving the traffic efficiency during peak hours, but ignores the personal safety of passengers. If all the passengers are "standing on the left and standing on the right", even if some passengers fall backwards on the way up, the passengers behind can also play a supporting role. -This is a serious misleading and deception, which will cause many people on the elevator to fall and get injured like dominoes.

Can't stand

In the media, it is always advertised that when riding the escalator, it should be in line with international standards, and walk left and stand right. A propaganda slogan was posted on the escalator of the subway, and a group of young volunteers spared no effort to dance, as if to persuade people to abandon darkness and vote for light. But there was no answer, and of course there was no me. I don't approve of changing to left-handed and right-handed. Although I have known this for a long time abroad, I can't stand this practice in Shanghai at present:

1. First of all, it is impolite to walk and run on the escalator. In a hurry? You can't squeeze much time into such a short escalator. Every time I watch someone rush along the escalator, I wonder why the old and wide pedestrian steps next to the escalator can give full play to everyone's speed, but they have to be squeezed on the narrow escalator. It's like taking a narrow path to speed up when there is an expressway, and blaming other cars on the road for taking up space.

We are used to standing in two rows on the escalator. Why? Just look at the crowd pouring out behind the subway station. Do you want dark people to gather on the platform and wait for them to stand to the right one by one? Quality will bow to tight resources. Twenty years ago, I got on the bus in Shanghai without queuing. Now you can queue up to get on the bus. Not because I went to college, but because I know there are enough cars and enough space. When the People's Square subway station can have 50 escalators, I will follow this suggestion.

Pseudocivilization

As far as I know, only subways in Britain and other countries have such regulations, and other countries do not. As Hong Kong, Singapore and other places were originally British colonies, this provision was also implemented in the past. However, after the return of Hong Kong, the government began to gradually abolish some laws and regulations with colonial characteristics. At present, it is not recommended to stand left and right on the subway in Hong Kong.

First, contrary to the subway design: there is generally only one escalator at an exit of the subway, and the stairs next to it are for people who are in a hurry. Going left and standing right will reduce the capacity. You know, in places like Hong Kong and Japan, there are often more than three escalators or even no stairs at the exit.

Second, it is easy to cause the platform to be crowded: the transportation capacity caused by standing left and right will be reduced, which will inevitably make the platform personnel unable to evacuate in time and easily lead to accidents.

Third, it is harmful to pedestrians: escalators in subways often break down because of frequent use. Friends who often take the subway will inevitably encounter several sudden stops of the escalator, resulting in a scene of one trip. If passengers are walking on the escalator at this time, the footwall is unstable and may be injured. In some countries, when passengers are found walking on escalators, the staff will discourage them. And should our country advocate it?

condition

The present situation of "walking left and standing right" 1: "walking left and standing right", which has been regarded as a symbol of civilization for many years, is actually unscientific and prone to accidents when walking on escalators. Hong Kong Metro changed "station left and station right" to "enterprise setting" [1]. The staff of Guangzhou Metro Company reminded that "walking left and standing right" is not a "safety criterion", and the subway believes that it is most important to stand firm and support.

Status quo 2: In fact, in Hong Kong, which is regarded by many as a model of "walking left and standing right", the government and the subway have stopped advocating this behavior in recent years. A spokesman for the Electrical and Mechanical Services Department (EMSD), the Hong Kong government agency in charge of elevator safety, said that EMSD does not encourage people to walk on escalators because people who walk tend to lose their balance and fall. Since then, the Electrical and Mechanical Services Department has issued special guidelines, pointing out that walking on escalators is dangerous. Under the guidance of the government, the MTR Corporation, the operator of the Hong Kong subway, has stopped advocating "walking left and standing right" in recent years, and replaced it with the propaganda slogan of "holding the handrail and standing still".

"Walk left and stand right" Status 3: All escalators in Guangzhou Metro have posted the slogan "Please pay attention to safety and stand firm" to guide passengers to use escalators safely. Many passengers don't have a good habit of grabbing handrails, and once they encounter an emergency, they are prone to accidents. Especially passengers with babies, don't forget to hold the handrail with both hands.
