  Cell Phones Increase Traffic, Pedestrian Fatalities

  Cell phones are a danger on the road in more ways than one. Two new studies show that talking on the phone while traveling, whether youre driving or on foot, is increasing both pedestrian deaths and those of drivers and passengers, and recommend crackdowns on cell1 use by both pedestrians and drivers.

  These studies looked at cell phone use and motor vehicle accidents from 1975 through 2002, and factored in4 a number of variables, including vehicle speed, alcohol consumption, seat belt use, and miles driven. The studies found the cell phone-fatality correlation to be true even when including factors such as speed, alcohol consumption, and seat belt use.

  However, this was not the case when cells were first used in the mid-1980s, when they caused a life-taking effect among pedestrians, drivers and passengers in vehicles. In those early days, when there were fewer than a million phones, fatalities increased, says Loeb, because drivers and pedestrians probably were still adjusting to the novelty of using them, and there werent enough cell phones in use to make a difference in summoning help following an accident, he explains.

  Loeb and his co-authors used econometric models to analyze data from a number of government and private studies. He and his co-authors recommend that governments consider more aggressive policies to reduce cell phone use by both drivers and pedestrians, to reduce the number of fatalities.
