I. Introduction
Autonomous path-following is an important ability applied by autonomous guided vehicles (AGVs) and self-driving vehicles (SDVs). AGVs are employed extensively by the warehousing and manufacturing industries to lower operational costs and improve production efficiency [1], with modern guidance techniques for AGVs involving either fixed paths or computer-determined paths [2]. Unlike AGVs, fully autonomous SDVs are still in their research and development stage [3]. Once improvements in the developments of SDVs allow them to be commercially available, their anticipated advantages include the environmental benefits of reducing fuel consumption, air pollution, and carbon emissions, and the public safety advantage of reducing traffic accidents [4].
