While drunken driving may be on the decline, traffic safety experts remain puzzled over how to deal with
another alcohol related danger: drunken pedestrians (行人).
Pedestrians struck and killed by cars often are extremely drunk. In fact, they are intoxicated more
frequently, and with higher blood alcohol levels, than drunken drivers who are killed in accidents, various
studies have shown. Forty percent of adult pedestrians involved in fatal crashes have a blood alcohol level of
at least 0.10, which by law in many states signifies intoxication (醉酒), compared to only 25 percent of drivers
in deadly accidents, according to recent federal data.
Some types of pedestrian accidents have been declining nationally, especially those involving children, but
the number of adult pedestrians who are drunk when killed in traffic has remained relatively steady at 2,500 a
year. The total number of pedestrians killed annually in U.S. traffic accidents is at least 7,000, or one of every
seven highway accidents resulting in death.
"We're dealing here, we think, with a very severe drinking problem that leads to a severe highway safety
problem," said Richard Bloomberg, president of Dunlap and Associates Inc, in Norwalk, Coon.
Bloomberg, whose consulting company found a very high rate of alcohol involvement in a controlled study
of pedestrian accidents in New Orleans, was among several researchers who spoke on the topic at the annual
meeting of the Research council's Transportation Research Board (TRB) in Washington in January.
Pedestrian accidents have not received enough attention in the past, according to Kay Culprits, who chairs
the board's committee on pedestrians. Few methods exist to monitor walking habits, she said, and researchers
have been confused about how to prevent disasters.
