To better prepare for the task of identifying advanced technologies that may be incorporated in future highway systems, a scanning team was assembled to survey European planning and applications of advanced technologies. This advanced technology scanning team was drawn from Federal and State highway agencies, the National Institute of Standards and Technology, and Carnegie Mellon Research Institute. These experts in various advanced technologies met with experts in Denmark, Germany, France, and the Netherlands. Their objectives were to: assess the state of ongoing research in evolving computer-based technologies such as artificial intelligence, data visualization, etc.; assess support for longer range, high-risk research ventures; determine how these countries get innovations tested and into practice; and define technologies in which the United States can collaborate on joint research and development efforts. The team identified several technical projects that should be considered for followup. This report consists of: (1) an executive summary; (2) introductory information; (3) country summaries describing what was observed in each country in the following categories: management, design and decision-support tools, traffic management, data management, sensors, computational methods, and global positioning systems/geographic information systems applications; (4) a description of how various countries address specific technical subjects, such as traffic control, pavement management, materials research, etc.; and (5) an identification of areas and countries that should be followed up on through in-depth technical exchanges and cooperative or coordinated research. |
