As of 2001, the Department of Transportation had established an Intelligent Vehicle Initiative (IVI) the goal of which was to improve significantly the safety and efficiency of motor vehicle operations by reducing the probability of motor vehicle crashes as a major component of the Intelligent Transportation System (ITS) program. As part of the IVI, NHTSA evaluated the performance of CWS and adaptive cruise control (ACC) by participating in field operational tests of vehicles equipped with advanced safety systems. In May 2005, NHTSA released the results of its passenger vehicle testing, Automotive Collision Avoidance System Field Operational Test Final Program Report, showing potential to reduce rear-end crashes by 10 percent and reporting positive user reaction to the systems.
The final report on the commercial vehicle field testing conducted for the U.S. Department of Transportation by Battelle and Volvo Trucks North America, Inc., was released in January 2007. The preliminary findings of the report indicate that a combined CWS and ACC bundled safety system account for a statistically significant reduction in rear-end crashes through reduced exposure to safety-critical driving scenarios. The Board has requested but has not yet received any information on NHTSA’s interpretation of the commercial vehicle testing or timeline for future actions to mandate use of this technology.
NHTSA, along with its cooperative partners the FHWA, the FMCSA, and RITA appears to be working consistently, although slowly, on this important technological safety issue. The preliminary results of the testing on advanced safety systems are encouraging, but rulemaking is needed to ensure uniformity of system performance standards, such as obstacle detection, timing of alerts, and human factors guidelines, on new passenger and commercial vehicles.
