The applicatopn allows you to set the threshold parameters of people’s movement paths.
Evacuation Routes
People movement routes and exits with a height of less than 1.9 meters and a width of less than 0.7 meters are not taken into account when compiling an evacuation calculation scheme, except for cases established in fire safety regulations.
This requirement is applied in the application automatically. Therefore, if the distance between two obstacles is less than 0.7 meters, or there are obstacles in the path of movement at a height of less than 1.9 meters, then people will not proceed there.
In some cases it is necessary to set up specific parameters of the evacuation routes. For example, if there is a turnstile on the evacuation route.
To set up the evacuation route parameters, do the following:
- Navigate to Simulation | Evacuation Simulation Parameters.
- Switch to the Evacuation Routes tab.
- Select the desired scenario.
- Enter the desired parameter values.
- Click Apply.
Simulation Control
When the Interrupt simulation, when people remain in the high-density flow for a long time option is selected, the application automatically interrupts simulation when people are located in the high-density human flow longer than the specified period of time.
You can specify the critical density of the human flow and define the maximum time period during which people are located in the high-density human flow.
When the evacuation simulation is interrupted, you can analyze evacuation results and make necessary changes to the scenario, so that people spend less time in the high-density human flow.
According to the methodology for determining the individual fire risk for buildings of various fire danger classes, if the duration of congestion (human flow density exceeds 0.5 m²/m²) exceeds 6 minutes, then the probability of evacuation equals zero. These values are used by default.
Therefore, if at any point of the simulation the duration of congestion exceeds 6 minutes, there is no need to continue the evacuation simulation, as the fire risk will most likely exceed the maximum threshold value, and it is necessary to develop additional fire safety measures.
Regardless of the critical people flow density values and maximum threshold time set in the evacuation simulation parameters, the application always uses a density of 0.5 m²/m² when calculating fire risk to determine the duration of congestion.
