 - The path candidates generated there are referred to by the main thread, and the one judged to be valid for the current planner data (e.g. ego and object information) is selected from among them. valid means no sudden deceleration, no collision with obstacles, etc. The selected path will be the output of this module.
 - If there is no path selected, or if the selected path is collision and ego is stuck, a separate thread(freespace path generation thread) will generate a path using freespace planning algorithm. If a valid free space path is found, it will be the output of the module. If the object moves and the pull over path generated along the lane is collision-free, the path is used as output again. See also the section on freespace parking for more information on the flow of generating freespace paths.
