Parameters

	)

private

Creates a speed profile according to case one or two of the light controlled intersection, where the vehicle accelerates (then cruises if needed) and decelerates into the intersection.

Parameters

wm	world_model pointer
points_and_target_speeds	of centerline points paired with speed limits whose speeds are to be modified:
start_dist	starting downtrack of the maneuver to be planned (excluding buffer points) in m
remaining_dist	distance for the maneuver to be planned (excluding buffer points) in m
starting_speed	starting speed at the start of the maneuver in m/s
departure_speed	ending speed of the maneuver a.k.a entry speed into the intersection m/s
tsp	trajectory smoothing parameters NOTE: Cruising speed profile is applied (case 1) if speed before deceleration is higher than speed limit. Otherwise Case 2. NOTE: when applying the speed profile, the function ignores buffer points beyond start_dist and end_dist. Internally uses: config_.back_distance and speed_limit_

private

Creates geometry profile to return a point speed pair struct for INTERSECTION_TRANSIT maneuver types (by converting it to LANE_FOLLOW)

Parameters

maneuvers	The list of maneuvers to convert to geometry points and calculate associated raw speed limits
max_starting_downtrack	The maximum downtrack that is allowed for the first maneuver. This should be set to the vehicle position or earlier. If the first maneuver exceeds this then it's downtrack will be shifted to this value.
wm	Pointer to intialized world model for semantic map access
ending_state_before_buffer	reference to Vehicle state, which is state before applying extra points for curvature calculation that are removed later
state	The vehicle state at the time the function is called
general_config	Basic autonomy struct defined to load general config parameters from tactical plugins
detailed_config	Basic autonomy struct defined to load detailed config parameters from tactical plugins

Returns: A vector of point speed pair struct which contains geometry points as basicpoint::lanelet2d and speed as a double for the maneuver NOTE: This function is a slightly modified version of the same function in basic_autonomy library and currently only plans for the first maneuver

◆ isLastTrajectoryValid()

bool light_controlled_intersection_tactical_plugin::LightControlledIntersectionTacticalPlugin::isLastTrajectoryValid	(	const rclcpp::Time &	current_time,
		double	min_remaining_time_seconds = `0.0`
	)		const

private

Checks if the last trajectory plan remains valid based on the current time.

This function verifies that the previously generated trajectory still meets timing and duration requirements. It can also enforce a minimum remaining duration if specified.

Parameters

current_time	The current time stamp.
min_remaining_time_seconds	Optional parameter specifying the minimum required remaining time (in seconds) for the trajectory to be considered valid.

Returns: True if the last trajectory is valid, false otherwise.

Parameters

config The new config to be used by this object

private

Determines whether the last trajectory should be reused based on the planning case. Should use last case if 1) last traj is valid AND last case is the same as new case, OR 2) last traj is valid AND within certain evaluation zone before the intersection where the new case is not successful but last case is.

Parameters

new_case	An enumerated type representing the new trajectory planning case.
is_new_case_successful	A boolean flag indicating if the new trajectory planning was successful.
current_time	The current time stamp.

Returns: True if the last trajectory should be used, false otherwise.
