Defining walking behavior
You can define different walking behaviors and assign them to an area behavior type and to the pedestrians of a pedestrian type. Walking behavior is comparable to driving behavior (Defining driving behavior in a driving behavior parameter set).
To link the walking behavior to a construction element, assign the area behavior type selected for it to the desired walking behavior. You select the area behavior type via the Behavior type attribute of the construction element. In area behavior type, you can define a special walking behavior for each pedestrian class (Defining area behavior types). You can also assign several walking behaviors to one area behavior type.
If no area behavior type is selected for an area, ramp or stairs or if an area behavior type has not been assigned a walking behavior, the walking behavior assigned to the pedestrian type is used.
The following default walking behaviors can be predefined:
| Element | Description |
|---|---|
| Elevator (in cab) |
Walking behavior of pedestrians in an elevator cab The default walking behavior differs from the Noise parameter = 0.3 (walking behavior default = 1.2). This means the pedestrians in the elevator cab are not moving much. |
| Elevator (alighting) |
Walking behavior of pedestrians alighting from an elevator car to continue their route in the area in front of the elevator. The following parameters differ from the default walking behavior:
These values allow passengers alighting from the elevator cab to easily pass other passengers. |
1. On the Base Data menu, click > Walking Behaviors.
The Walking Behaviors list opens. The columns in the list also contain model parameters per pedestrian type according to the social force model (Defining model parameters per pedestrian type according to the social force model).
By default, you can edit the list (Using lists).

Note: In lists, you can use the |
2. Right-click in the list.
3. On the shortcut menu, click Add.
A new row with default data is inserted.
4. Enter the desired data.
| Element | Description |
|---|---|
| No |
Unique number of walking behavior |
| Name |
Name of walking behavior |
| The following columns contain model parameter values (Defining model parameters per pedestrian type according to the social force model): | |
|---|---|
| Tau |
Relaxation time or inertia that can be related to a reaction time Default value 0.4 s Tau will be set to 0.8 s for pedestrians that wait in front of a red signal head. This allows for realistic passing of approaching pedestrians and calm waiting behavior of pedestrians in stationary state. As soon as the signal head turns green, Tau is reset to the default value. |
| ReactToN |
React to n: During calculation of the total force for a pedestrian, considers only the influence exerted by the n closest pedestrians. |
| ASocIso |
A social (isotropic) and B social (isotropic) govern the force between pedestrians. |
| BSocIso |
B social (isotropic) and A social (isotropic) govern the force between pedestrians. |
| Lambda |
Lambda governs the degree of anisotropy of the forces. |
| ASocMean |
A social (mean) governs the strength (A) of the social force between two pedestrians. |
| BSocMean |
B social (mean) governs the range (B) of the social force between two pedestrians. |
| VD |
Parameter VD in seconds |
| Noise |
The greater this value, the stronger the random force that is added to the systematically calculated forces if a pedestrian remains below his desired speed for a certain time. Noise is set to 0 for pedestrians waiting in front of a red signal head. This allows for realistic passing of approaching pedestrians and calm waiting behavior of pedestrians in stationary state. As soon as the signal head turns green, Noise is reset to the default value. |
| Side preference | Specifies whether opposing pedestrian flows prefer using the right or the left side when passing each other. |
