The District Department of Transportation just released a big report on traffic accidents in D.C. from 2010 through 2012. We mapped the intersections where the most crashes were reported during those three years.
The blue pins mark the 20 intersections where the highest number of crashes took place. These intersections are in each quadrant of the city except Southwest, with six east of the Anacostia, just one west of Rock Creek, and the other 14 in between.
The No. 1 site of the most accidents was New York Avenue and Bladensburg Road NE. From 2010 through 2012, 226 crashes occurred at that intersection.
New York Avenue appears on the top 20 list more than any other road. Six of its intersections, including two in the Langdon neighborhood in Northeast and four on a half-mile stretch that runs through NoMa, accounted for 934 crashes.
What may be more interesting to drivers wondering where their risk of a collision is highest is the green set of pins. These represent the 20 intersections with the highest rate of crashes — the worst ratios of cars that got into accidents versus those that drove through safely.
The single most likely place to get into a car crash in D.C. in 2010 to 2012, it turns out, was 14th and U streets NW, followed by Wisconsin Avenue and M Street NW, then 19th Street and Independence Avenue SE.
For all its accidents, New York Avenue is actually comparatively safe, given the huge number of cars that drive it every day. None of its intersections make the list of the 20 crossings with the worst crash rates.
Southern Avenue, which runs along the border between the District and Maryland, turns out to be among the worst offenders in terms of crash rate. Three of its intersections made the top 20 list, as did two intersections just one block apart on Seventh Street NW in Chinatown.
The Howard University researchers who compiled the traffic accidents report analyzed these intersections in more sophisticated ways, including something called a “crash composite index” which takes into account the severity of the collisions, too. You can dive into the whole report here.
And before you start redrawing your commute to avoid the trouble spots on this map, remember that a host of other factors influence car accidents. The report also looked at the influence of gender, speed, time of day and much more.
