Tokyo Wants People To Stand on Both Sides of the Escalator (citylab.com)
When one side isn't reserved for walkers, it saves time for everyone. But transit users around the world just can't be convinced. Linda Poon, writing for CityLab: I'm one of those people who speed past everyone on the escalator. As long as the left side isn't blocked, no amount of judgement from fellow riders to the right, or safety warnings, or even falls (two and counting) will stop me -- not yet anyway. I'm certainly not alone; it's a common enough habit that some cities occasionally try to change such behavior for safety's sake. London's tried, so has Hong Kong and Washington, D.C. Now it's Tokyo's turn. East Japan Railway Company (JR East) launched a campaign this month calling on riders to stand on both sides of the escalators inside some of the city's busiest transit hubs.
Signs are posted on walls and above escalators, reading, in both Japanese and English, "Walking on escalators may lead to accidents caused by collisions or luggage." Bright pink handrails carry similar messages. And in some stations, security staff with neon-colored vests stand watch and guide people. If people are really in a hurry, JR East suggests, they should take the stairs. So far, the effort has had mixed results: According to the Japan Broadcasting Corporation (NHK), railway officials say that some people did stop but many commuters were still hustling up and down the escalator on Monday. The campaign is set to run until February 1.

I think I saw some research that actually when using both sides of escalator it actually increases the amount of people goes though. But the argument leaving other side free is to let those who are in the hurry walk and rest who are not that in a hurry just stand.
I guess you've never been the Japan. It's not universal but it is a very frequent habit for standers to stay to one side and walkers to freely use the other. They're not particularly wide and I'm an Amerifat but still manage not to clog up the escalator like a double-handrail-holding can't-fucking-balance jackass.
What are you doing touching the rails anyway--you want to pick up the latest cold or flu going around?
These are probably up/down escalator sets both going the same direction. One side is just standing and the other is used by walkers. I think they could just make it so that walking is only permitted when there's no congestion and everyone is happy.
This isn't for safety. It's to reduce lines of people waiting on the escalator. Maybe you've never been somewhere that busy before?
Maybe this is a stupid question, but why not just take the stairs if you're in a hurry? Maybe it's different in Japan or there are a few locations where this doesn't hold true, but I'm assuming that there's a perfectly good set of stairs that can be used instead of escalators. If I'm in a hurry in an airport, I'll almost always take the stairs because they get a lot less traffic and they're often more than wide enough to allow plenty of space to go around people.
I find it surprising that people can operate their legs on normal stairways, yet their legs stop operation when on stairs that move.
Same goes with moving pathways at airports.
How lazy.
"When one side isn't reserved for walkers, it saves time for everyone."
This is an absurd claim that doesn't pass the most basic smell test.
If everyone is a stander, then the latency for everyone is fixed once they are on the device. Therefore, the only way to "save time for everyone" is for everyone to literally have to wait extra time to get on otherwise. That is clearly NEVER the case for everyone and is, in most instances, never the case for ANYONE.
If the most important thing is absolute throughput, then you need to pack like sardines to minimize wait on entry. This is likely never true except in an exceptional place during exceptional demand. Otherwise, it will always be best to yield space to those who need to minimize transit time since your latency will be unaffected. This is so trivially easy to understand it's a joke.
It's not wonder "transit users around the world just can't be convinced", it's because it's wrong. Laughably wrong.
When in a hurry, I often find the stairs are faster than the crowded escalator.

And "little" is racist.

What the featured article refers to as "the city’s busiest transit hubs" you might indeed call "an exceptional place". Besides, the article appears to imply that in JR East's opinion, the most important thing might be neither throughput nor latency but collision safety, particularly for people carrying bulky and/or heavy luggage.

This is frequently the case even when only a small number of people are using an escalator. If you're in a hurry and physically capable, the stairs are almost always a better option.

These are probably up/down escalator sets both going the same direction. One side is just standing and the other is used by walkers. I think they could just make it so that walking is only permitted when there's no congestion and everyone is happy.
And that would be a "social contract" kind of thing, where society's social norms would need to be adjusted. That's hard to do.

Two at a time standing maybe makes sense if there are enough people at the bottom of the escalator to saturate it - i.e. a big enough crowd at the bottom that there are always two more people to step on each step as it appears.That is logically the maximum throughput, if you assume that people walking up leave spaces between them. If you had a pool of fit people who all wanted to get up the escalator as fast as possible, then they could all walk, or, god forbid, run up the escalator and the increased velocity would likely offset the effect of the spaces and you would achieve even greater throughput.
Around here the transit stations are busy, but seldom at saturation levels. People stand on the right and walk on the left. Seems to work well enough. Most people walk up, the ones who stand are usually pulling a suitcase, or elderly, or obese, or heads down reading a book or a screen.

It's bad enough when some bureaucrat wants to protect us from ourselves, even when they have their facts right. Doing it when they are wrong is just adding insult.
And unlike those sillies on the escalator, you won't be stuck on the stairs in the event of a power outage. :D
This space unintentionally left blank.
are you retarded? if an escalator is void of people, running up or down the escalator is significantly faster than stairs.
No, the signs aren't lying. But if being accurate about the motivation leads to lower compliance then they'll change the story to engage people's social imperatives.
Throughput obviously decreases when someone decides to stand on the left side. How the hell did you reach the opposite conclusion?
Only if you put a higher priority on walkers. If there's still a love on the non-walker side, then it's not optimal for the general case. All it takes it one walker to prevent the side from being used by lots of non walkers.
What stairs? Plenty of London stations only have escalators.
SJW n. One who posts facts.
It's only when traffic volume exceeds a certain level that double-standing makes sense. But if it's not clear when "double time" is, the confusion can cause problems and injuries.
You need explicit and standardized timed signs.

I ignore the posted signage unless there's someone in authority to give me a hard time about it.
It even has symbol painted on the ground showing right side as immobile and left side as walking. Frankly most people also stick to right side even when not prescribed e.g. frankfurt hbf people stick to the right side or go to the right side when they hear you climbing.

People in Wyoming get stranded on escalators for hours when they lose power!

No, in Japan the escalators in the subways are mostly wide enough for a double-file line on the same escalator.
"First they came for the slanderers and i said nothing."
Complete failure. Possibly because of the nightmarish idiotic posters that they had to promote this. Made me want to throw up.
Not just in Japan. I've been to quite a few countries in Asia, and the escalators are all "double-wide". In most places I've been, there are actually signs that say some version of "stand on the right, walk on the left".
A few years back Prague public transport tried something similar. They attempted to convince people to stop standing only on one side of the escalators. The reason was completely different. When people stand on one side, then this side is being worn out more than the other one. This was causing some troubles with servicing escalators. Apart from that I don't see any problems with allowing people in a hurry to walk/run the escalators. Especially when there are no stairs to run around the problem. BTW: if you walk on escalator, then you are always faster than someone on stairs :). If it comes to question of capacity, then it surly will win standing on both sides. But life is not always about maximum capacity.
Let's call the escalator speed "1". If you have an escalator capable of holding two persons per step, the output would be 2/step-arrival if everyone stands still.
If 25% of the users are walkers, and ascend twice as fast as the escalator, that would result in a 2/sa metric. If more than 25% use the "walk" lane, throughput increases. If fewer use it, throughput decreases.
The critical factor is not "have a walk lane or not", it's "how do people use the escalator". And that is completely ignoring the "perception factor". A certain setup may be less efficient than the optimum, but if people like it better, it should be used. The amount of time and money spent dealing with complaints about the "better" system almost always outweigh the efficiency benefits.
Wreck less people ruin it for the considerate. Where stairs are an option fine hog the escalator. But Most people can stand to the right and let those in a hurry move faster. The point should be made if you have luggage use left side, no passing. Otherwise if space permits stand to the left. There are times where folks with luggage need to use right side since crowded in which case tough luck for those who want to go fast. Likewise for less mobile people old / handicap , babies etc have right to stay on right. Able body people should be considerate and step to the left to allow those non right to pass. This will continue with a few jerks making life difficult unnecessarily for others.
It's known as a general courtesy around the globe that this is how it's done and if you block the left you're a bloody cunt.
City governments may be looking at uneven wear patterns on bearings, rollers or belts that an escalator uses. I am guessing that keeping maintenance cycles down they would be saving money. I think it's in the cities best interest to let the faster people out front instead of forcing 300+ people cross the intersection at the same time.
~ People that think they are better than anyone else for any reason are the cause of all the strife in the world.
The correct side to stand on depends on where you are. In Osaka and the surrounding region we stand on the right side. Only clueless out-of-towners from Tokyo would be dumb enough to stand on the left blocking busy commuters.
I would personally find it frustrating to be blocked when there is clear space beyond the blockage that I could be walking up. I have a train to catch.
I'm in Osaka right now and they already have floor signs making people to stand in 2 queues for each escalator.. well, as I saw the traffic in subway hubs, I do understand.

That's a valid point. But there's an easy solution to that: Alternate the sides. A lot of highways in the US have signs that say "Trucks use X lane". That lane changes to move the heavy vehicles to different lanes (and, thereby, extending the life of the road). It would be a simple (and cheap) solution to have digital signs that say "Stand on X side, Walk on Y side".
And... now you've tweaked my "inner engineer" to wonder which side puts more stress on the system. The "standing" lane is a constant, static load. The "walking" lane is an intermittent, dynamic load (of higher frequency).
Are there any mechanical engineers (or maintenance workers) who can chime in?
Am I the only one finding it weird that most of people stop as soon as they get on the escalator? Why wouldn't you keep going?
This is why I don't like big cities and mass transit. At the end of the day, all humanity gets reduced to automata. You are not a person with your own goals and desires. We much force you into a box that exactly matches all the other boxes so that we can increase efficiency. Step on the escalator, ignore your personal space and sidle up next to the other person that you have never met as if you're best friends.
No, thank you.
