Pedestrians struck and killed by cars often are extremely drunk. In fact, they are intoxicated more frequentlyand 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. 10which by law in most states signifies intoxication 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 deaths.

　　Pedestrian accidents have not received enough attention in the past, according to Kay Colpitts, who chairs a boards committee on pedestrians. Few methods exist to monitor walking habits, she said, and researchers have been mystified about how to prevent mishaps.

　　Studies have revealed some of the causes, which range from a lack of adult supervision for many children involved in accidents to long delays in traffic signals that may encourage jaywalking, speakers said at a meeting. The most challenging problem, however, is alcohol. Some researchers suspect that part of the problem, ironically, may be former drunken drivers whose licenses were suspended and who now are walking. Other researchers, emphasizing the larger social problem of alcohol abuse in general, say many drunken pedestrians are poor alcoholics who often face lonely deathsand not only on highways.
