Drivers navigating the Washington area know that some intersections can be particularly dangerous, even without the choking traffic that plagues the region.
Motorists stumped by New York Avenue and Florida Avenue NE in D.C. can know they're not alone in nerve-wracking near-misses when crawling through that intersection:
It was one of D.C.'s top hot spots for accidents in the past year, tying with the junction of Pennsylvania Avenue SE and the Anacostia Freeway.
The Washington Examiner analyzed area police departments' lists of intersections having the most crashes in their jurisdictions. Experts warned against comparing jurisdictions, as each one collects and records crash data differently. Fairfax County did not provide crash information.
But the lists do remind drivers to be alert when steering through places like Four Corners in Silver Spring, at the intersection of Colesville Road and University Boulevard, which had 51 collisions last year -- the most in Montgomery County. Or when driving down Alexandria's Duke Street, whose intersections landed the thoroughfare in nine of the top 10 slots for accidents in the city, for a total of 172 crashes.

"It is paramount for motorists to always pay attention," said Dave Buck, a spokesman for the Maryland State Highway Administration. "Clearly when you come up on these more congested intersections, the potential for conflict points in a crash increases, and therefore you need to be in a heightened state of awareness."
Buck said most incidents result from driver errors, such as failure to pay attention, driving too fast or driving under the influence.
But some intersections are designed poorly -- or could use a few tweaks to help prevent accidents. Arlington engineers recently rebuilt a signal at the intersection of Arlington Boulevard and South George Mason Drive, where the county had 25 crashes in the past year, to help drivers see it better, said Arlington traffic engineer Wayne Wentz.
Officials from area jurisdictions regularly comb accident reports to identify road flaws that could have contributed to crashes.
"If we identify an intersection that has a high number of collisions -- and we're going through this systematically -- we then look at all the features, the striping, the signing, the signal timing," Wentz said.
For some pesky intersections, there's not much that can be done. The interchange at Arlington Boulevard and South Washington Boulevard saw 45 accidents from May 2012 to April 2013 -- the most of any intersection in Arlington County -- but state engineers say the interchange was built in 1944, back when design standards and cars were different, and now development around the roads makes expanding or reworking the intersection difficult.
"The standards have evolved as we've learned more about how people behave and how drivers drive. To build it properly -- there's just no room there," said Ivan Horodyskyj, a traffic engineer for the Virginia Department of Transportation.
Many intersections in the Washington region are handling more cars than they were designed for, wearing out faster than planners in cash-strapped governments can fix them, said AAA Mid-Atlantic's Lon Anderson.
But even without major fixes, educating drivers and enforcing the rules of the road go a long way toward keeping accidents down, officials said.
"The engineering part of it can only do so much," said Buck. "It's driver attention, keeping the speed down. It's watching out for pedestrians -- things like that."
