I don't think people comprehend how incredibly dangerous crowds can be when not carefully controlled and influenced by well planned processes and design. The Halloween crush in Korea killed 159 people in just minutes, and there was no stopping it from happening until it was far too late. This is such an important and underappreciated type of design and psychology, glad to see content focusing on it.

[@SkyFlame27]

Actually horrifying. I was almost at that but decided last minute to hang with friends somewhere else instead. The thought of not being able to move and people screaming, fainting and dying next by you with no way out is terrible. I’m so thankful for that last minute change of plans.

Just couple of days ago in India a stampede happened killing 121 people just because of the lack of preparation for crowd control

[@Alphoric]

I know people can comprehend that based on historic events that killed people due to crowd crushes. There are dozens of cases sometimes with hundred of deaths. Indonesia 2022 - 133 die in a crowd crush at a football match India 2013 - 115 die in a crowd crush at a religious festival Ivory Coast 2013 - 60 die in a crowd crush after a fireworks event Mecca 2015 - 2300 die in a crowd crush during the Hajj pilgrimage England 1989 - Hillsborough disaster 97 die in a crowd crush during a football match People know about crowd crushes

[@FelixAufYoutube]

Similar thing happened in Germany during Love Parade in Duisburg, 2010. 21 People died because they locked off ways to exit the area and were crushed in tunnels. This lead to one of the biggest cases in court where they had to rent fair halls for the trial. There’s even an english Wikipedia article. It ultimately lead to very strict guidelines for events in Germany.

[@Zebedee777]

I work in the events industry and let me tell you A LOT of thought and work goes into tiny aspects of crowd management. Even the specific size and shape of the pit barrier. Where I used to work we had people on towers at music shows just monitoring how the crowd was moving and behaving from above to try and spot potential issues before they developed. Of course there have been some recent high profile disasters, but these underpin how important this subject is. Crowds have a mind of their own and can make people behave very differently.

[@MartijnPennings]

Sadly things have gone wrong a lot before people started planning this better. Brings to mind a Pearl Jam concert imat Roskilde festival in 2000 where 9 people were crushed due to a stampede. This lead to better crowd control during festivals, like the inner ring in front of the stage for "early bird" fans.

[@raygunsforronnie847]

@@MartijnPennings The Who at Riverfront Stadium in 1979 comes to mind.

[@Zebedee777]

@@MartijnPennings Videos of disasters like this one are actually shown in some of the training we do. When I did pit barrier installation training they showed multiple videos of crowd crushes and broke down in detail what caused them and how better safety precautions could have prevented them. As I said, it’s really hard to predict how a crowd is going to act on any given day and it’s affected by things like the weather, any delays to the schedule, alcohol consumption etc. Once it gets out of hand there is very little you can do, so our best shot is trying to avoid mistakes of the past. I think the worst recent example was the Astroworld crush. But the Brixton academy crush was very shocking and sad too.

The definition of art is weird. To me there's art, which usually stems from creativity and exists only to make people feel certain emotions or convey a message. Be it through painting, animation, music. But it doesn't serve any purpose. As an artist myself I need to make sure that we artists don't contribute anything useful to society.

Japan comiket has some of the best crowd controls I’ve seen and experienced. Multiple ways of transportation to get to the venue, ultra organized line to get in, and multiple ways to get out when the event is over.

[@dimitar297]

In India people trample over one another to catch the train.

[@Tailss1]

One crucial issue overlooked in this but is vitally important is how do you safely and efficiently evacuate large numbers of people safely and quickly in the event of en emergency. That is also the job of engineers.

[@FPVogel]

In Germany in arenas we usually build (depending on amount of people) two passageways to the left and right of the stage which are at least 3m wide for the people on ground level, so they can just go straight ahead and out. For everyone not on the ground there are emergency exits when standing up and going up the stairs and out. It also does depend on whether you have a standing or a seated crowd. For minor accidents/incidents you also may not want people to evacuate, in case your power went off for example, you still have emergency lighting and letting them evacuate then, you do not have any real control on guiding 10k+ people out.

[@owenskel4804]

How could you plan an evacuation of planet earth? You would need a team of engineers

[@funlovingvoyeur]

With an emergency, people are not waiting to look at posters, standing in a walking route to talk to each other, or crossing the street to go to a station. They want out and get away, never mind blocking a street or whatever. So people go in the same direction. Still worth a look (or many looks) as mostly the route out of a venue is small, hence why there are emergency doors.

The holy mosque in Makkah is also a perfect example of crowd control engineering. Amazing video.

[@littlekirby6]

the waiting in pens thing blows my mind. You're telling me you're having a huge sports crowd wait for a traffic light for a few cars to pass? Where I live, the few streets around the stadium are closed off temporarily. So it's not the whole city obviously, but it gives just enough room for people to disperse in different directions

[@july_fish]

i assume it would be more helpful to have the traffic light so people would enter the train station in batch

[@user28a7dj8e7]

The issue is that Earls Court Station is RIGHT there and there's not really anywhere else to go unless you happened to be staying in the immediately surrounding area. The road was basically just an excuse to create breaks in the flow of traffic of people leaving the stadium without anyone noticing that they were doing so.

[@ReallyRealBenMills]

I'm pretty sure that the road was closed. The real issue is that the station entrance is narrow, about the width of the sidewalk, so there was never any sense in allowing everyone to pile up at that entrance. It could turn into a lethal crowd crush very quickly.

[@TPixelAdventures]

@@ReallyRealBenMills why would they need to wait for the traffic lights if the road was closed, though? I suspect that the traffic was allowed to keep flowing to make people stop. Having a real threat like being run over by a vehicle is a good way to keep patience levels high. Plus, the feeling of "fairness" that everyone will eventually get their turn helps as well.

[@ReallyRealBenMills]

@@TPixelAdventures The purpose of the pens was to regulate the width of the crowd before the entrance did it the hard way. They weren't waiting for much actual traffic, but that's also the best way to clear access for emergency vehicles should the need arise. Barring the movement of emergency vehicles and event vehicles, they most likely didn't wait for the traffic lights, but instead, had event personnel letting groups out of the pens in sequence to smooth out the flow.

[@beavertonmike5818]

One time I was at Disney and I marveled at the psychology of the lines. You think you are almost to the ride but nope, it turns. But you feel you are making progress. Jump to the fireworks time, I thought I was smarter than their line system and tried to fight against the traffic. It was stupid and I should have realized they knew the best way to clear out.

Seen a dangerous situation in Edinburgh with an overcrowded platform, a fight broke out and people were almost falling onto the track trying to get out of the way.

[@MAjaLeahHB]

i went to wembley stadium for a sold out concert and i thought the way they handled the crowd was extreamly distressing. when you first get out of the venue you don't know why you can't just go in any direction, you get funneled somewhere but you're not sure exactly where (i think many people in the audience haven't been to the area before), you also can't move forward and people keep coming out of the venue pushing from behind. i saw so many people pass out in the crowd. i only went there once, so maybe things are usually different but i still remember how unsafe i felt.

The picture at 0:20 was from Rock im Park, a music festival in Germany, which is the absolutely worst organized event I have ever attended. It became worse after COVID for some reason, and keeps getting worse every year. This year was a new highlight, when after Green Day finished playing and the field was emptying, the crowd was filling the street and for some reason did not move at all. It took forever to walk a relatively short distance, and once we cleared the crowd we saw that there was no obstacle or anything that would have been a reason for the crowd to move this slowly. It was absolutely fascinating how this happened. My only explanation is that people wanted to move in both directions simultaneously, causing everyone to bump into others approaching them, slowing everything to a crawl.

[@tsbrownie]

Or escalators that empty into an area of equal size where people are expected to wait, like train station platforms. People reach the end, get off, and often just stand there or stop to get their bearings. During busy times, people getting off have no where to go and a crush starts forming as more people are dumped into the area off the escalators.

Entrance to Hyde Park events is usually well managed.

[@manus21]

Last weekend at the Taylor Swift concert: The arena adapted the disorganized queue and it was SO absurd. There were 5 or 6 security checks next to each other, so in theory people could have used all of them - but somehow there was ONE HUGE LONG queue in front of one security check - like, the line was ridiculously long. Apparently everybody coming to the venue thought that they had to queue in this single line. Some people walked by it, saw all the empty security checks next to the line and got in without long waiting times. This could have easily been avoided by adapting a different queuing system, like the Disney-Queue for example.
