Three local pedestrians have been killed by hit-and-run drivers this month, bringing to at least 17 the number of hit-and-run accidents involving people walking or riding bicycles in the region this year, according to statistics compiled by the American Automobile Association.

The most recent accident occurred early Sunday, police said, when a pedestrian was struck by a red Honda that fled the scene at the intersection of University Boulevard and Baltimore Avenue in College Park. Another pedestrian died after a hit-and-run early Friday on Arlington Boulevard in Arlington, police said. U.S. Park Police said a District woman was killed by a hit-and-run driver Sept. 9 as she walked westbound on Southland Parkway near Naylor Road. A second accident occurred the same day when a Montgomery County man was struck as he stepped off the curb at the intersection of Georgia Avenue and Windham Lane in Wheaton.

The AAA said that in 13 of the 17 hit-and-run accidents, the victim died. About 11 percent of crashes nationwide involve a hit-and-run driver, according to data compiled by the AAA Foundation for Traffic Safety. The National Highway Transportation Safety Administration reported an increase of 20 percent between 2000 and 2005 in the number of fatal hit-and-run accidents involving pedestrians.

In the Washington region, the Street Smart campaign says pedestrians and bicyclists accounted for about a quarter of all traffic fatalities between 2006 and 2010.

“The trend is troubling because it involves drivers who often willingly or knowingly flee the scene without rendering aid to the victim, making it a crime scene,” said John B. Townsend II of AAA. “That’s cold-blooded, inhumane and unconscionable.”

In addition to the three hit-and-run incidents this month, the 2011 list of accidents includes:
