Detailed Description

Lane-changing model based on the Gipps (1986) behavioral model.

This class manages the functionality for vehicle lane-changing decisions, according to the rules defined by Gipps's model. Vehicles decide when to overtake or return to their original lane based on traffic conditions and the parameters from the p_lcm_gipps class.

Constructor & Destructor Documentation

lcm_gipps() [1/2]

lcm_gipps::lcm_gipps

(

)

Default constructor for the Gipps lane-changing model.

Initializes the model with default parameters.

lcm_gipps() [2/2]

lcm_gipps::lcm_gipps

(

p_lcm_gipps *

p

)

Constructor for the Gipps lane-changing model with custom parameters.

Parameters

p	Custom lane-changing parameters.

Member Function Documentation

lch_left()

bool lcm_gipps::lch_left ( point * leader, point * subject, point * new_leader, point * new_follower, model * cfm, params * lcmpars )

overridevirtual

Determine if the vehicle should change lanes to the left.

The decision to change lanes to the left is based on the vehicle's speed relative to a fraction of the free-flow speed. If the speed is lower than a certain threshold, the lane change will be considered.

Parameters

leader	Current leader in the lane.
subject	Current vehicle's position and speed (follower).
new_leader	The vehicle to become the subject's leader in the new lane.
new_follower	The vehicle to become the subject's follower in the new lane.
cfm	A car-following model.
lcmpars	Lane-changing model parameters.

Returns

True if the lane change to the left is feasible, false otherwise.

Implements lcm.

lch_right()

bool lcm_gipps::lch_right ( point * leader, point * follower, point * new_leader, point * new_follower, model * cfm, params * lcmpars )

overridevirtual

Determine if the vehicle should change lanes to the right.

The decision to change lanes to the right is based on the vehicle's speed relative to a fraction of the free-flow speed. If the speed is higher than a certain threshold, the lane change will be considered.

Parameters

leader	Current leader in the lane.
follower	Current vehicle's position and speed (follower).
new_leader	The vehicle to become the subject's leader in the new lane.
new_follower	The vehicle to become the subject's follower in the new lane.
cfm	A car-following model.
lcmpars	Lane-changing model parameters.

Returns

True if the lane change to the right is feasible, false otherwise.

Implements lcm.
