Analyze your simulation and identify important key figures


How is your venue used? Which routes are heavily frequented? Where is space unused?

Agents can be coloured according to the routes they take. Identify crowded paths and areas with high levels of footfall.

Paths can be coloured according to various criteria. Visualize the paths of all or individual agents, coloured by origin, destination or agent ID. This allows you to quickly identify where agents are coming from or where they are going.

 How can pedestrian routes be evaluated?
In the graphic on the right, paths are coloured according to agents’ destinations. Areas in this building that are not accessed are clear. These passive areas can be used for other purposes.

How long does an evacuation take? How long does an evacuation take when other paths are used? How are the exits used?

You can analyse a completed simulation by inserting counting lines (tripwires) at various points. Then produce graphically summarized data in tables and diagrams. You'll find out:

  • The evacuation time
  • The time at which the first agent leaves an area
  • The "course" of the evacuation, i.e. how many agents crossed a line at a certain point in time, whether the flow was continuous or not, etc.

How can data from tripwires be evaluated?
The screenshot on the right shows that after about 3 minutes all agents have left the premises. The graphs are linear, which implies a continuous flow.

How many agents wait in a particular area?

Analyse the behaviour of agents in a selected part of the simulation. For certain areas within your plan, polygons can be used to perform a detailed analysis. You can evaluate the following and display it automatically in diagrams:

  • Waiting time
  • Density
  • Speed

How can areas of interest be evaluated?
The image on the right shows the analysis of a bottleneck using a polygon. It shows how many agents pass through the observation area during a selected period of time.

Analysis of a bottleneck.

Where are the bottlenecks? What is the Level of Service?

Heatmaps enrich floor plans by colour coding grids which lay over the floor, facilitating the analysis of simulation results. Heatmaps can be used to calculate a large number of key figures, for example:

  • RSET: Each tile describes the time at which the last agent left it to determine the required clearance time.
  • Density: Each tile describes how high the density is, quickly identifying bottlenecks.
  • Speed: Each tile describes how fast agents move in the tile (minimum, maximum, average) which evaluates the flow.

How can data from heatmaps be evaluated?
The graphic on the right shows an RSET heatmap. The darker the tiles, the later people leave this area when they are evacuated.

Can I change my reports? Do I always have to reset everything with every simulation?

You can change all evaluations in crowd:it. Freely select the data you wish to analyse and display the results as diagrams, curves, screenshots or videos. The colours and axes can be adapted according to your needs. You can also export, save and reuse all reports.

In the graphic on the right you can see the kind of data that can be displayed­­­­.

Can I produce a 3D video?

Yes. A 2D, birds-eye view video of your scenario is best for evaluation, however 3D is also possible. You can export and save videos and screenshots with a couple of clicks.
