Automatic vehicle identification to support driver information systems

The authors describe how research in automatic vehicle identification (AVI) technology can be transferred to practical transportation engineering situations. They focus on the development and implementation, for the Virginia Department of Transportation, of an AVI-based electronic toll collection system known as Fastoll. One of the most promising areas where the Fastoll system could be enhanced relatively easily is through the provision of improved real-time driver information for the avoidance of congestion. The authors consider the use of the Fastoll AVI technology to provide input to route guidance and other driver information systems.<>
