Car

The agent in the model.

The public methods in the car are:

class car.Car(starting_position, starting_velocity, braking_rate=25, acceleration_rate=10, max_velocity=60, desired_velocity=40, length=4, stop_space=8, safe_dist=100)

Definition of the Car class. Here Car can take several arguments during initialization.

Parameters:

• starting_position (float) – Starting position of the car
• starting_velocity (float) – Starting velocity of the car
• braking_rate (float) – Rate of retardation (braking rate) of the car
• acceleration_rate (float) – Rate of acceleration of the car
• max_velocity (float) – Maximum velocity that the car can reach up to
• desired_velocity (float) – The velocity of the car that it tries to achieve in normal case
• length (float) – Length of a car
• stop_space (float) – Space that the car must have between the car in the front before colliding
• save_dist (float) – A safe distance the car wants to have with the car in front

position_history

History of all position that this car has traveled

Type:list

return_position_array()

Give history of the array for plotting.

Returns:Return an array of positions for each time point in the simulation.

update_position(position_of_next_car)

Get the new position of the car after a single time step, based on the position of the car in front.

Update the position history of the car.

Parameters:position_of_next_car – distance to the next car including Returns:The position of the car after the next time step
