This working paper describes a proposed research plan to explore the application of advanced technology to highway vehicle navigation. The proposed research addresses navigation, communication, and control technology, benefits of improved vehicle navigation, system requirements, and design and implementation issues. The paper introduces the issues involvedin highway vehicle navigation and communication, and discusses recentdevelopments in vehicle navigation technology.The importance of a vigorous program of research in this area is identified, and six near term and ten follow-on projects are described, including provision estimates of the level of effort required
