Seems to me that formal studies would have more of an effect looking at how to manage crowds that are already too dense without making things worse. If you want to avoid the density in the first place, you decide on a maximum density within a central perimeter, and also manage density appropriately along the ingress routes. That way you don't just push the unsafe densities into the outer side of the perimeter. And you set your desired densities low enough to both avoid dangerous situations inside the central perimeter, and allow the central crowd to get out if there is a fire/etc. inside it.
Essentially if you want a max density in area A, you enforce some other max densities in the area several times larger than A.

(I believe there are larger migrations like China’s Lunar New Year, but those are more diffuse since it’s more people to hometowns.)

- bobthepanda 2y agoI admittedly don’t know very much about that festival. One interesting thing about Hajj is that not only is travel to a specific place mandated but also travel in a specific path and direction; you need to walk around the Kaaba seven times and walking between the hills of Safa and Marwah seven times. Given the Kaaba is only 12m x 10.5m its a very small place to concentrate people in.
