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 you're 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.
The new studies， lead-authored by Rutgers University， Newark， Economics Professor Peter D. Loeb2， 136 ， showing that the current increase in deaths resulting from cell phone use follows a period when cell phones actually helped to reduce pedestrian and traffic fatalities. However， this reduction in fatalities disappeared once the numbers of phones in use reached a “critical mass” 3 of 100 million， the study found. These studies looked at cell phone use and motor vehicle accidents from 1975 through 2002， 137 ， 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.
Loeb and his co-author determined that， at the current time， cell phone use has a “significant adverse effect on pedestrian safety” and that “cell phones and their usage above a critical thresholds adds to motor vehicle fatalities.” In the late 1980s and part of the 1990s， before the numbers of phones exploded， cell phone use actually had a “life saving effect” in pedestrian and traffic accidents， Loeb notes. “Cell-phone users' were able to quickly call for medical assistance when involved in an accident. This quick medical response actually reduced the number of traffic deaths for a time，” Loeb hypothesizes.
However， 138 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， 139 ， and there weren't enough cell phones in use to make a difference in summoning help following an accident， he explains.
The “life-taking effect” occurred as the volume of phones grew into the early 1990s， 140 explains Loeb. But this life-saving effect was canceled out once the numbers of phones reached a “critical mass” of about 100 million and the “life-taking effect”. increased accidents and fatalities outweighed the benefits of quick access to 911 services， according to Loeb.

Loeb2， 136 ， showing that the current increase in deaths resulting from cell phone use follows a period when cell phones actually helped to reduce pedestrian and traffic fatalities.
A、this was not the case when cells were first used in the mid-1980s.
B、because drivers and pedestrians probably were still adjusting to the novelty of using them.
C、and factored in a number of variables.
D、relate the impact of cell phones on accident fatalities to the number of cell phones in use.
E、Loeb and his co-authors used econometric models to analyze data from a number of government and private studies
F、to reduce the number of fatalities
G、and increasing numbers of cells were used to call 911 following accidents， leading to a drop in fatalities
