The implementation of vehicle-highway automation early in the 21st century will provide an enhanced level of surface transportation accessibility and mobility. Vehicle-highway automation technologies and systems can be described in four categories: warning systems that sense and then advise drivers of potential hazards, control assistance systems that augment the driver's ability to control the vehicle, control override systems that intervene in some aspect of the control of the vehicle during unsafe conditions, and automated control systems that control all motions of the vehicle. Automation has the ability to generate fundamental changes in transportation, including improvements in safety, spurred economic development, reduced traffic congestion, and extended mobility for many, especially the elderly and disabled. This paper describes some probable directions, recognizing that the actual future depends mostly on how transportation automation opportunities evolve and integrate with the future needs of individuals and society. |
