Parameters of the Social Force Model in VISSIM
7.6 Parameters of the Social Force Model in VISSIM
The parameters of the model can be categorized into three groups:
1. Parameters of the original model (by pedestrian type).
2. Parameters of the model extensions for VISSIM (by pedestrian type).
3. Implementation-specific global parameters include all discretization
parameters: E.g. for models formulated using a continuous time. As
analytical approaches to solve the differential equations are only possible
in scenarios of limited size in any respect, time needs to be discretized in
some way to make a simulation on a computer possible.

7.6.1 Model Parameters by Pedestrian Type
For each type of pedestrians, parameters derived from the original model
can be set. Furthermore additional VISSIM-specific parameters can be set by
pedestrian type.
