Abstract

See full text

An intelligent vehicle highway system requires a multi-functional roadway reference system to help the vehicle locate its lateral and longitudinal position along a highway. This information at a minimum is required to control the vehicle. The present invention consists of a roadway reference system in which discrete markers installed in the center of a traffic lane code one or more bits of information. An on-board sensing system acquires the information when the vehicle passes over the reference markers and thereby determines vehicle deviation and upcoming road geometry. Other coded information may be provided through the passive discrete markers to include such items as geographical position, warning of future conditions and the like.
