Attention to driver acceptance and performance issues during system design will be key to the success of the Automated Highway System (AHS). A first step in the process defining driver roles and driver-system interface requirements for AHS is the definition of system visions and operational scenarios. These scenarios then become the basis for first identifying driver functions and information requirements, and, later, designing the driver`s interface to the AHS. In addition, the scenarios provide a framework within which variables that potentially impact the driver can be explored systematically. Seven AHS operational scenarios, each describing a different AHS vision, were defined by varying three system dimensions with special significance for the driver. These three dimensions are: (1) the degree to which automated and manual traffic is separated, (2) the rules for vehicle following and spacing, and (3) the level of automation in traffic flow control. The seven scenarios vary in the complexity of the automated and manual driving maneuvers required, the physical space allowed for maneuvers, and the nature of the resulting demands placed on the driver. Each scenario describes the physical configuration of the system, operational events from entry to exist, and high-level driver functions.
