A Roadway Information System for Vehicle Guidance/Control

This paper describes the principle of an Intelligent Roadway Reference System (IRRS). It discusses both the sensing and communication capabilities of an IRRS. It then assesses the information capability of an IRRS, focusing on the ability for providing static information for an Intelligent Vehicle Highway System (IVHS). This paper also investigates the information representation methods and indicates that some of the static information needed for IVHS can be conveyed by an IRRS.
