Evacuation in terms of reduced gravity


With the advent of multiple colonization programs, located off earth and in low gravity environments, there is a need to focus on safety procedures and standards in the habitable spaces.

As living hubs and habitable spaces get larger the complexity of layout and necessary systems becomes greater. Contemporary knowledge shows the more people in an environment without fully prescribed behavior, the higher the required complexity of the habitat and the more redundant safety systems there must be.  Emergency systems for egress of 10 people significantly differ from those for 50 people.

Safety of the people is a top technical priority in every enclosed habitat under any environmental conditions. It follows therefore, the design of a base, colony or even a city in orbit or on a planetary surface complies with this principle.

Each space related project of habitable volume must assume different scenarios for people’s behavior during emergency situations. The base must provide as much failsafe shelter as possible which can be used under panic or failure of training situations.

Functional, structural, engineering and construction method solutions as well as adequate procedures must provide efficient emergency egress sufficient for the number of people able to be in a space at any one time.

This evacuation process is one of the key elements in saving human lives in emergency situations within hostile environments.

The evacuation processes are based on the mechanics of locomotion of those involved. The reduced gravity inherent to these situations significantly influences single human movement as well as crowd formation and flow. Although the locomotion of individual humans is well studied in different gravitational conditions, the crowd formation and influence on safety design does not appear to have been focused on within that research.

Human movement mechanics in low gravity environments is different enough to state that crowd behavior will not follow predictions made in standard gravity conditions. This indicates that mistakes in planning may result in casualties and injuries.

This project focuses on high-level methods and major guidelines for preparing data for evacuation processes in low gravity environments.

The purpose is to formulate guidelines for evacuation strategy and reiterated design policies in low gravity environments.

The methods used to obtain the highest standards in safety design are multi-iterated software simulations of crowd movements with constant upgrade of assumed solutions. These methods can be used to help in the design and maintenance of construction methodology and quality.

The project is going to develop in two major directions:

Explore crowd formation and movement in terms of changeable locomotion conditions (and collision avoidance) in terms of reduced gravity

Explore different base sizes to seek for differences between safety guidelines and safety measures

We are gratefull Thunderhead Engineering for suporting our work!
Thunderhead Engineering provides simulation software:
Pathfinder  -an Agent based simulation software
PyroSim – Fire Dynamics Simulatoer (FDS)

Those simulators are critical in RSET (Required Safe Egress Time) and ASET (Availabe Safe Egress Time) calculations.
With formulas you may find in the video above we may introduce Mars and Moon based walking speeds and simulate the emergency situation there.

imagine you have to tweet it to you wife and she has to understand it 🥸
Szymek (Simon) Matkowski May 18, 2022 @ 7:26am
you must equip safety zone with independent basic Eclls ssytem... etc etc.
Szymek (Simon) Matkowski May 18, 2022 @ 7:26am
so i take a base. run a simulation and say - to maintain eg.10min time - you need to provide 2 safey zones
Szymek (Simon) Matkowski May 18, 2022 @ 7:25am
hehe, kind of mind bending making guidelines for base design to provide maximum evac posibility
Cimmero (Enrico) May 17, 2022 @ 11:48pm
Can you explain this in half the words? I find it difficult to follow
Szymek (Simon) Matkowski May 16, 2022 @ 6:14pm
Hi. I am working on the table (for 3 different sizes) based on SFPE guide to human behavior in fire - Chapter VI. Factors and Considerations in Human Behavior Analysis for different Habitat sizes https://docs.google.com/document/d/1J7W3B4AxrQCOxN2-PaPUlXklF62oDrkN9VoeNZpMph8/edit#heading=h.h30ditx0umkh maybe there is someone willing to check it out or write some thoughts? @​Cimmero (Enrico) ?
Szymek (Simon) Matkowski May 14, 2022 @ 4:29pm

Oh I was not aware. So you have the original link?
Szymek (Simon) Matkowski May 12, 2022 @ 9:13pm
Szymek (Simon) Matkowski May 12, 2022 @ 9:13pm
Gee Cemron. It is already on NA siet
rough93 May 12, 2022 @ 8:12pm
@​Szymek (Simon) Matkowski were you able to finalize a logo?
Szymek (Simon) Matkowski May 10, 2022 @ 12:39pm
Szymek (Simon) Matkowski May 10, 2022 @ 12:39pm
NA design
Szymek (Simon) Matkowski May 10, 2022 @ 12:38pm
This is really what I need:
Szymek (Simon) Matkowski May 10, 2022 @ 12:31pm
wow. i did not count for any new design... That would be the best! For 1000 I will use old Twardowsky base.
Cimmero (Enrico) May 10, 2022 @ 10:48am
I can definitely do something, will be fun!
Szymek (Simon) Matkowski May 10, 2022 @ 10:30am
i was considering B.Mckenzie Mars Homestead - but it is way to small https://www.space.com/1419-homestead-project-making-mars-settlement-reality.html Also I got a project Novum http://sicsa.egr.uh.edu/sites/sicsa/files/files/projects/novum2016canaanmartinmastersthesisbook.pdf with greater potential for quick adaptation.
Szymek (Simon) Matkowski May 10, 2022 @ 10:15am
best if plan - I can deduct from 3D model as well. I have practice with NA CityState competition models . the design matters.
Cimmero (Enrico) May 9, 2022 @ 9:55pm
You mean like a plan, a 3d model?
Szymek (Simon) Matkowski May 9, 2022 @ 6:10pm
@​Cimmero (Enrico) Hi Enrico. Maybe you can help with some ideas of 100 people bases that are - big enough (100 and above people) to have an impact on the design - authors can share estimated habitat population layout (in terms of age) - best if they are at least 2 level – to study vertical emergency egress impact - they are modular or at least divided into sections - best if they are provided with differentiation of habitable volumes (so there are possible mass gatherings vs small passages or cabins) - the location is irrelevant – it may be Mars or Moon – I am going to use the same design on both gravitation conditions
Szymek (Simon) Matkowski May 8, 2022 @ 1:44pm
super! so I will confirm my presence in Brno on 12-14.09 gee it is going to be a hot period
bigred May 8, 2022 @ 1:42pm
yes i think there is no problem with that as long as you represent it as NA and the authors. We signed those contracts with NA exactly so we can retain the ability to publish where ever we want
Szymek (Simon) Matkowski May 7, 2022 @ 4:30pm
@​bigred do you think i can present the same material - but let's say as a powerpoint presentation? not to mention to upload same whitepaper?
Szymek (Simon) Matkowski May 6, 2022 @ 7:30pm
Yep. I need to write iaf for permission for same material presentation I think
rough93 May 6, 2022 @ 6:53pm
Wow that's great! It's hosted by the same company that sponsored our license right?
Szymek (Simon) Matkowski May 6, 2022 @ 5:14pm
Wow. I was invited to be a presenter on FEMTC conference.
Szymek (Simon) Matkowski May 5, 2022 @ 6:43pm
bit it concerns mostly their soft
Szymek (Simon) Matkowski May 5, 2022 @ 6:43pm
they have also additional programming manual.
Szymek (Simon) Matkowski May 5, 2022 @ 6:43pm
Hi @​Orion Lawlor - Alaska in fact this soft provider gives full mathematical data on their product - i imagine this may interest you to compare algorithms here is a link to their Technical manual: https://support.thunderheadeng.com/docs/pathfinder/2022-1/technical-reference-manual/
Orion Lawlor - Alaska May 5, 2022 @ 7:47am
Neat project! Decades ago I did a project where we simulated evacuation from a room with up to thousands of people--the code is ancient Windows C++ but should be considered public domain, and the basic approach and data structures should work with anything: https://www.cs.uaf.edu/~olawlor/projects/1999/mcm_99/index.html I'd like to update this project at some point!

I checked out the project on staging and looks great! @​Szymek (Simon) Matkowski let me know if / how I can help!
rough93 May 2, 2022 @ 4:02pm
and once you've finalized the logo @​Szymek (Simon) Matkowski @​luna<3 (Rose) can get it onto the merch store
rough93 May 2, 2022 @ 4:02pm
@​Szymek (Simon) Matkowski Definitely, go ahead and create the folders in the drive since you have permission, I'll set you up with channels on the server. @​Betamaxx (James) if you could help out with getting a new project page online for this project that would be awesome
Szymek (Simon) Matkowski May 2, 2022 @ 10:57am
I can publish myself, but I 'd rather like to coordinate
Szymek (Simon) Matkowski May 2, 2022 @ 10:56am
I also need to make a call for specialists - I need help or at least a discusussion on what I do - I think I would need also a long distance overlook on my goals to get feedback if I am moving in right direction (as the subject is huge and it is impossible to put all in one simple 10 pages paper)
Szymek (Simon) Matkowski May 2, 2022 @ 10:54am
and also make a final link on webpage
Szymek (Simon) Matkowski May 2, 2022 @ 10:53am
@​Cameron (SSAM) is it possible to receive a full project on NA as I have requested in a form or you see it other way? I need to make some sub folders - except CHAT
Szymek (Simon) Matkowski May 1, 2022 @ 7:12pm
