Typical questions of simulations and how they can be answered with analyses
How is the total area used? Which routes are heavily frequented? Where is space left?
Agents can be colored according to their walking routes. Use them to identify busy routes and high-traffic areas.
Paths can be easily colored according to different criteria. Visualize the paths of all or individual agents, colored by origin, destination or ID. This allows you to quickly see where agents are coming from or going to.
How can paths be evaluated?
In the graphic on the right, the paths are colored according to the destination of the agents. You can see very clearly that there are areas in this building that remain unused. These passive areas can be used for other purposes.
Pathways of all agents
How long does the overall evacuation take? How long does the evacuation take depending on the escape route? How are the available exits used?
Tripwires can be inserted at various points in order to measure flow rates etc. The data of these tripwires can be summarized in tables and diagrams.
Thereby one learns:
- The total evacuation time
- The time at which the first agent leaves an area.
- The flow rate of the escape, i.e., how many agents crossed a line at a given time, whether the evacuation was continuous or staggered, etc.
How can tripwires be evaluated?
The screenshot on the right shows that after about 3 minutes all agents have left the site. The graphs are linear, which implies a continuous outflow.
Evacuation times of different exits
How long is the queuing or waiting time? How many people are in a particular area?
Analyze the behavior of the agents in a selected part of the scenario. For specific areas within your plan, a detailed analysis can be performed with polygons. You can evaluate the following measures and display them in diagrams:
- Waiting time, queuing time
How can detailed analyses be evaluated?
The picture on the right shows the analysis of a bottleneck using a polygon. It shows how many agents pass the area of interest in a selected time period.
Analysis of a bottleneck
Where do bottlenecks occur? What is the level of service?
Heatmaps enrich spatial plans with information by color coding, which facilitates the analysis of simulation results.
To create heatmaps, the floor is divided into measurement tiles. This allows a variety of metrics to be calculated, such as:
- RSET: Each tile describes when agents last crossed it to determine the required evacuation time.
- Density: each tile describes how high the density is in that area to quickly identify bottlenecks.
- Speed: Each tile describes how fast agents move in the area (minimum, maximum, average) to evaluate flow rates.
How can heatmaps be evaluated?
The graph on the right shows an RSET heatmap. The darker the tiles, the later people leave that area during an evacuation.
Can I change my reports? Do I always have to reset everything every time I run a simulation?
You can modify all evaluations in crowd:it, freely select the data to be analyzed and display the results as diagrams, curves, screenshots or videos. The colors and the scales can be customized according to your wishes.
Moreover, you can export all the analyses and save your favorite reports to re-use them at any time.
Right you can see which info can be selected by "drag&drop" and displayed in a curve.

Is there also a 3D video?
A 2D video from the top view is the best way to evaluate a scenario. To present your results to all stakeholders, you can export and save them.
For a modern presentation, you can also visualize the simulation in 3D.
