Use of Advanced In-Vehicle Technology by Young and Older Early Adopters: Survey Results on Adaptive Cruise Control Systems. Traffic Safety Facts

摘要

Adaptive cruise control (ACC) is an in-vehicle convenience feature designed to maintain a set speed and, when applicable, adjust the set speed to maintain a specified distance from a lead vehicle. When following another vehicle, the ACC system will automatically slow down or speed up in responses to changes in the lead vehicles speed. Adaptive Cruise Control systems are still relatively new technologies and are not widely available within the U.S. passenger vehicle fleet. One in eight Americans is 65 or older, and this proportion will continue to grow as the American population ages. It is possible that new technologies such as ACC can assist older drivers to drive more safely with less stress, thus extending their safe driving years. It is also possible that ACC may cause unintended consequences such as over-reliance on the technology. The research reported here was conducted as part of a broader study to learn more about driver experience with several emerging in-vehicle technologies. The focus of this study is on how these technologies are being used and how well their function and limitations are understood, with a particular emphasis on the experiences of older drivers.
