INVESTIGATION OF ALTERNATIVE DISPLAYS FOR SIDE COLLISION AVOIDANCE SYSTEMS

Abstract

: Side Collision Avoidance Systems (SCAS) are designed to warn of impending collisions and can detect not only adjacent vehicles but vehicles approaching at such a speed that a collision would occur if a lane change were made. Side object detection systems (SODS) represent a subset of SCAS; they warn of the presence of adjacent vehicles only, whether or not there is a lane change. Despite a measure of success in producing first-generation SODS devices, relatively little is known about Driver Vehicle Interface (DVI) requirements for these complex human-machine systems. The DVI is important because it affects the ability of drivers to detect, understand, and correctly respond to the warning information presented by the system. In the current study, a large range of alternative SODS DVI designs were identified and evaluated to determine potential DVI characteristics that enhance driver acceptance. Key issues, including driver preferences for the format, location, and symbology of SODS...
