Collision Free Speed Model V2

This is a variation of the Collision Free Speed Model where geometry and neighbor repulsion are individual agent parameters instead of global parameters.

A general description of the Collision Free Speed Model can be found in the originating publication https://arxiv.org/abs/1512.05597

A more detailed description can be found at https://pedestriandynamics.org/models/collision_free_speed_model/

class CollisionFreeSpeedModelV2AgentParameters[source]#

Agent parameters for Collision Free Speed Model V2.

See the scientific publication for more details about this model https://arxiv.org/abs/1512.05597

Note

Instances of this type are copied when creating the agent, you can safely create one instance of this type and modify it between calls to add_agent

E.g.:

positions = [...] # List of initial agent positions
params = CollisionFreeSpeedModelV2AgentParameters(v0=0.9) # all agents are slower
for p in positions:
    params.position = p
    sim.add_agent(params)

position[source]#: Position of the agent.

time_gap[source]#: Time constant that describe how fast pedestrian close gaps.

v0[source]#: Maximum speed of the agent.

radius[source]#: Radius of the agent.

journey_id[source]#: Id of the journey the agent follows.

stage_id[source]#: Id of the stage the agent targets.

strength_neighbor_repulsion[source]#: Strength of the repulsion from neighbors

range_neighbor_repulsion[source]#: Range of the repulsion from neighbors

strength_geometry_repulsion[source]#: Strength of the repulsion from geometry boundaries

range_geometry_repulsion[source]#: Range of the repulsion from geometry boundaries
