Used as a description/spec for traffic actors (e.x. Vehicles, Pedestrians, etc). The defaults provided are for a car, but the name is not set to make it explicit that you actually want a car.

accel: float = 2.6

The maximum acceleration value of the actor (in m/s^2).

decel: float = 4.5

The maximum deceleration value of the actor (in m/s^2).

depart_speed: float | str = 'max'

The starting speed of the actor

emergency_decel: float = 4.5

maximum deceleration ability of vehicle in case of emergency

property id: str

The identifier tag of the traffic actor.

imperfection: Distribution = Distribution(mean=0.5, sigma=0)

Driver imperfection within range [0..1]

junction_model: JunctionModel

lane_changing_model: LaneChangingModel

max_speed: float = 55.5

The vehicle’s maximum velocity (in m/s), defaults to 200 km/h for vehicles

min_gap: Distribution = Distribution(mean=2.5, sigma=0)

Minimum gap (when standing) in meters.

sigma: float = 0.5

The driver imperfection

speed: Distribution = Distribution(mean=1.0, sigma=0.1)

The speed distribution of this actor in m/s.

tau: float = 1.0

The minimum time headway

vehicle_type: str = 'passenger'

The configured vehicle type this actor will perform as. (“passenger”, “bus”, “coach”, “truck”, “trailer”)
