Application of a Crash Prevention Boundary Metric to a Road Departure Warning System

摘要

The U.S. Department of Transportation is actively involved in assessing the benefit of road departure warning systems (RDWS). A crash prevention boundary (CPB) metric has been proposed as one means of objectively measuring system performance. This paper presents the results of applying the CPB metric to data collected during the validation of an experimental RDWS. Two types of road departure warning scenarios are examined: curve speed and lateral departure.
