Recommended Objective Test Procedures for Road Departure Crash Warning Systems



Sandor S. Szabo, Richard J. Norcross


Under the auspices of the Department of Transportation Intelligent Vehicle Initiative, the National Highway Traffic and Safety Administration (NHTSA) is evaluating the safety benefits of Road Departure Crash Warning Systems (RDCWS). These systems warn inattentive drivers when their vehicle is about to depart the road or collide with a roadside obstacle. To further understand the capabilities and benefits of these warning systems, NTHSA, with the assistance of the National Institute of Standards and Technology (NIST), is devising test procedures that provide performance data in an objective and quantitative manner. These tests will evolve to reflect new insight into performance measurement and to maintain pace with the capabilities of the warning systems. In the long term, these tests may one-day become part of a standard procedure developers follow to achieve a safety rating similar to the 5-star ratings used in the automotive industry today.
