Software for simulating crowd flows
We have been developing software for microscopic, agent-based simulation and analysis of people flows for more than 10 years. It is based on the Optimal Steps Model and is continuously developed further based on the latest scientific findings. We have called it crowd:it.

NEW: Macroscopic Calculation Models
We have now introduced the first macroscopic calculation method into our microscopic simulation software crowd:it:

Microscopic Simulations
In microscopic simulations, each person is represented with their individual path. This results in more accurate outcomes and allows for detailed studies on bottlenecks, congestion times, and evacuation processes.
Pros:
- Precise modeling possible
- More accurate results, including process simulations
Cons:
- Longer and more complex modeling
- Longer computation times


Macroscopic Models
Macroscopic calculation methods enable quick estimations. Established manual calculations in fire protection can be easily implemented in crowd:it, and the results can be extracted.
Pros:
- Quick results
- Rough estimations
- No precise modeling of geometry required
Cons:
- Limitations with complex geometries
- Less accuracy
- Modeling errors can quickly lead to incorrect results

- Individual properties can be mapped using your own agent types
- Realistic representation of vertical connecting elements: stairs, elevators, escalators
- Flow charts and processes
- Timetables
- Highlighting and analysis of individuals
- Analysis of measurement lines, individual areas, special objects
- Individually adjustable heatmaps (RSET, density, velocity...)
- Special reports for congestion analysis

What's inside crowd:it

crowd:it was created in 2013 as part of Dr. Angelika Kneidl's dissertation. Since then, the software has been continuously developed with a great deal of knowledge, passion and dedication. Our software team consists exclusively of experts who have been trained in software development as well as modeling and simulation.
It is very important to us that crowd:it is and remains up-to-date, which is why the latest research results are constantly being incorporated into model development. We work very closely with universities in Germany and around the world.
We work with crowd:it ourselves on a daily basis, so we can quickly see where we can improve processes, incorporate new features and make the entire operating process more user-friendly.
In addition to a good user experience, we are committed to ensuring that our software is always valid - with every major release we run RiMEA tests and validate our software with multiple validation suites. You can read more about our validation process here
Our customers use crowd:it for:
- Fire safety certificates - Building law applications
- Event planning indoor - outdoor
- Planning and dimensioning train stations
- Occupational safety
- Analyzing visitor flows in
- Stadia
- Museums
- Airports
- Concert halls
- Theaters
