| 摘要： | With the increasing popularity of cellular phones and public concern about the safety of using phones while driving, there has been increased interest in tracking the incidence of driver cell phone use. This report provides a detailed look at the 2002 data on this topic from the National Highway Traffic Safety Administration, data that comes from NHTSAs National Occupant Protection Use Survey. The survey estimated that during daylight hours, drivers of cars, trucks, vans, and sport utility vehicles used hand-held phones during 4 percent of their driving time in 2002, up from 3percent in 2000. These results were obtained by observing actual traffic. In fact the NOPUS is currently the only source of probability-based observed national data on driver cell phone use. While the NOPUS percentages are small, they indicate a substantial and growing phenomenon, translating into approximately 600,000 drivers on the road at any given time between 8 a.m. and 6 p.m. using hand-held phones in 2002, up from 400,000 in 2000. When combined with data from other surveys on hands-free use, NOPUS finds that nearly 900,000 drivers on the road at any given daylight time are using cellular phones in some manner, whether by holding the phone or using a hands-free device. However, while NOPUS finds an increase in hand-held use behind the wheel, the survey data indicates a shift toward the use of hands-free devices. The growth in hands-free use while driving that occurred between 2000 and 2002 outpaced the growth in hand-held phones (a 33 percent growth for hand-held phones, compared to 100 percent for hands-free). NOPUS first observed cell phone use in 2000, and so the data in this report represents some of the first direct measurements of this form of driver distraction on the road. |
