Abstract
A method and system for facilitating cost effective, reliable, system redundant, self-driving vehicles involves the employment of specialized lane marking components that permit unprecedented sensor feedback, and in particular, a system and method that enables accurate lane marking recognition despite adverse weather conditions, which presently pose problems experienced by self-driving systems that rely upon vision based camera systems.
