Cell phone users tie up traffic

If you're late for work, <A HREF="http://www.eweek.com/article2/0,1759,2242896,00.asp?kc=EWKNLEDP010308D">a driver using a cell phone may be to blame.</A> U.S. researchers said on Wednesday that people who use cell phones while behind the wheel impede the flow of traffic, clog highways and extend commute times. Prior studies have equated the risk of driving while talking on a cell phone with driving while drunk. Some 50 countries have banned use of hand-held phones while driving.

The latest study shows the impact of cell phone use on traffic patterns. "It has to do with the reaction to changes in speed," said Martin, who teaches civil and environmental engineering.
