Social force model default parameters
Potentials
SFM potential (obstacle) in the default is significantly higher (20.1) than for the SFM Tests (10.0) as well as in helbing-1995 (10.). That is U_{\alpha B}^0 = 10 m^2/s^2 (code: obstacleBodyPotential
)
SFM pedestrian potential differs from helbing-1995: pedestrianBodyPotential
(should be V_{\alpha \beta}^0), according to helbing-1995 2.1 m^2/s^2, the default in the simulation is 2.72.
The other two parameters of the potentials, pedestrianRecognitionDistance
or \sigma
as well as obstacleRepulsionStrength
or R
align with helbing-1995.
