Detailed Description

Abstract class for lane-changing models.

This class handles the logic for determining whether a vehicle should change lanes based on its current state, the state of nearby vehicles, and model-specific parameters.

Member Function Documentation

is_lch_possible()

virtual bool lcm::is_lch_possible ( point * leader, point * follower, point * new_leader, point * new_follower, model * cfpars, params * lcmpars )

protectedpure virtual

Check if a lane change is possible.

This method determines whether a lane change is feasible, based on the position and speed of the leader and follower in both the current lane and the target lane.

Parameters

leader	Current leader in the lane.
follower	Current follower in the lane.
new_leader	New leader in the target lane.
new_follower	New follower in the target lane.
cfpars	Car-following model parameters.
lcmpars	Lane-changing model parameters.

Returns

True if the lane change is feasible, false otherwise.

lch_left()

virtual bool lcm::lch_left ( point * leader, point * follower, point * new_leader, point * new_follower, model * cfpars = nullptr, params * lcmpars = nullptr )

pure virtual

Determine if the vehicle should change lanes to the left.

This method computes whether the subject vehicle should change lanes to the left, based on the position and speed of nearby vehicles and the lane-changing model parameters.

Parameters

leader	Current leader in the lane.
follower	Current follower in the lane.
new_leader	New leader in the target lane.
new_follower	New follower in the target lane.
cfpars	Car-following model parameters.
lcmpars	Lane-changing model parameters.

Returns

True if the lane-changing maneuver is feasible, false otherwise.

Implemented in lcm_gipps, and no_lch.

lch_right()

virtual bool lcm::lch_right ( point * leader, point * follower, point * new_leader, point * new_follower, model * cfpars = nullptr, params * lcmpars = nullptr )

pure virtual

Determine if the vehicle should change lanes to the right.

This method computes whether the subject vehicle should change lanes to the right, based on the position and speed of nearby vehicles and the lane-changing model parameters.

Parameters

leader	Current leader in the lane.
follower	Current follower in the lane.
new_leader	New leader in the target lane.
new_follower	New follower in the target lane.
cfpars	Car-following model parameters.
lcmpars	Lane-changing model parameters.

Returns

True if the lane-changing maneuver is feasible, false otherwise.

Implemented in lcm_gipps, and no_lch.
