1. A vehicle system for determining lanes of a roadway, the system comprising:
an optical sensing arrangement including at least one video camera secured to a vehicle for sensing front images relative to the vehicle, including sensing metallic lane striping from photoelectric effect of photoelectrons generated by light from vehicle headlights or light from other sources; and
an electronic control unit including an electronic processor and a memory, wherein the electronic processor is configured to:
determine a location of the metallic lane striping defining a traffic lane based on a location of the photoelectrons emitted from the metallic lane striping that define a border of a traffic lane,
determine a location of metallic paint from a vehicle body of another vehicle based on a location of the photoelectrons generated from the metallic paint of the another vehicle, and
provide at least one from a group of vehicle operations consisting of: lane control to ensure the vehicle maintains proper position in a traffic lane, lane warning assistance, collision avoidance, parking control, and guidance for autonomous driving.
