Detailed Description

Parameter class for the linear car-following model.

This class stores the parameters used in the linear car-following model. These parameters include:

• Free-flow speed (V): The desired speed when no vehicles are ahead.
• Coefficients (c1, c2, c3): Constants that control the sensitivity to speed and spacing differences.
• Jam spacing (sr): The minimum distance maintained between vehicles when stopped.
• Reaction time (tau): The time it takes for the driver to react to changes in the vehicle ahead.

These parameters are essential for simulating vehicle behavior in traffic flow.

Constructor & Destructor Documentation

p_linear() [1/2]

p_linear::p_linear

(

)

Default constructor for p_linear.

Initializes the parameters with default values based on typical traffic conditions: Free-flow speed = 120 km/h, reaction time = 4/6 seconds, and default coefficients for speed and spacing.

p_linear() [2/2]

p_linear::p_linear	(	double	V,
		double	c1,
		double	c2,
		double	c3,
		double	sr,
		double	tau )

Constructor with custom parameter values.

This constructor allows setting custom values for the linear model parameters.

Parameters

V	Free-flow speed in m/s.
c1	Coefficient for speed difference sensitivity.
c2	Coefficient for follower's speed difference sensitivity.
c3	Coefficient for spacing sensitivity.
sr	Jam spacing in meters.
tau	Driver's reaction time in seconds.
