Over the next 20 years, advanced driver information systems for North America will evolve through three stages: (1) the information stage, (2) the advisory stage, and (3) the coordination stage. For each stage, this paper describes the goals, vehicle equipment and infrastructure, expected benefits, research and development required, deployment issues, obstacles and constraints. A series of operational field tests are defined for evaluating the systems at each stage. The paper concludes with an outline of standards which will be required. This information was developed at a series of workshops sponsored by Mobility 2000 under the leadership of the Federal Highway Administration.
