The District Department of Transportation will deploy its latest pedestrian-activated traffic signal at a high-traffic intersection where four months ago an elderly woman was struck and killed by an oncoming vehicle.

The newest HAWK—or high-intensity activated crosswalk—signal will go online next Wednesday at 11:30 a.m. at the intersection of Florida Avenue and 11th Street NE. That’s where on March 21, a Maryland driver killed 71-year-old Ruby Whitfield in a hit-and-run incident. Whitfield in the crosswalk, and was walking home with two indviduals just after leaving practice for a church event.

HAWK signals, which were first installed in D.C. in April 2012, uses sensor technology to change lights when pedestrians are present at high-traffic, high-speed intersections. The signals stay dark when no pedestrians are present, allowing vehicles to barrel through unimpeded. When somebody approaches on foot, the HAWK signal cycles through flashing yellow and then solid yellow to warn drivers to slow down before stopping on two solid red lights. The red lights then blink before traffic resumes.

The driver, Joel R. Bromwell, later pleaded guilty to involuntary manslaughter and driving under the influence of alcohol and will be sentenced in D.C. Superior Court on Aug. 30. He faces up to 30 years in prison, as well as a fine of up to $1,000 for the drunk driving charge.
