Currently, Volpe is using the driving simulator for an experiment for the National Highway Traffic Safety Administration (NHTSA) to examine how the driver-vehicle interface
affects drivers' abilities to cope with unintended acceleration.
Virginia Tech's infrastructure-cooperative system contains the following components: a roadside traffic signal controller that provides information about signal phase and timing, an infrastructure-to-vehicle communications system, an in-vehicle global positioning system (GPS) receiver and associated roadway map representation, and an in-vehicle computer and driver-vehicle interface.
Based on information from these four methods, ACAS can predict the curvature of the upcoming roadway more accurately, locate the closest vehicle in the path of the host vehicle, provide warnings to the driver about potential hazards via a driver-vehicle interface, and control the speed of the host vehicle through the brake and throttle when the driver uses the adaptive cruise control.
The design of the driver-vehicle interface - the place where the driver interacts physically and mentally with the vehicle - is critical.
Over time, IVI expects that intelligent vehicles will advance in three primary ways: in the capabilities of in-vehicle systems, in the sophistication of the driver-vehicle interface, and in the ability of vehicles to communicate with each other and a smart infrastructure.
Driver-Vehicle Interface Will Become Increasingly Sophisticated
In addition, more sophisticated voice recognition systems will be incorporated within the driver-vehicle interface.
Research described in this document is part of an effort to develop initial design guidance for vehicle-to-infrastructure (V2I) safety messages provided using driver-infrastructure interfaces and driver-vehicle interfaces
