Parameters for Social Force Model

All attributes are initialized with reasonably good defaults.

See the scientific publication for more details about this model https://doi.org/10.1038/35035023

bodyForce[source]#

describes the strength with which an agent is influenced by pushing forces from obstacles and neighbors in its direct proximity. [in kg s^-2] (is called k)

friction[source]#

describes the strength with which an agent is influenced by frictional forces from obstacles and neighbors in its direct proximity. [in kg m^-1 s^-1] (is called \(\kappa\))

bodyForce: float = 120000[source]#
friction: float = 240000[source]#
class SocialForceModelAgentParameters[source]#
