The Bowser administration announced on Tuesday that it will retime traffic signals at 93 intersections in Wards 6, 7, and 8 as a part of the mayor’s Vision Zero Initiative, which aims to eliminate pedestrian fatalities by 2024.

All the lights will be retimed starting on November 2, giving pedestrians a head start on cars turning on a green light.

Already this year, 31 people have died in traffic, bike, or pedestrian crashes—more than the year-end total of 30 people in 2017. Traffic fatalities have fallen dramatically from their all-time high of 72 people in 2001, but fatalities have increased every year since the mayor launched Vision Zero in 2015.

As the number of deaths has risen, the cycling community in particular has pressured Bowser to take immediate action to reduce them.

The District Department of Transportation identified 93 of all 227 traffic signals in targeted area that needed retiming, according to a press release from the agency. The area is mainly in Navy Yard and in “high volume areas” in Wards 7 and 8, where”data-testing has recognized the greatest need,” the agency says.

More than 50 percent of this area will now have pedestrian walk lights with “leading pedestrian intervals,” meaning pedestrians are given their walk signal a few seconds before cars are given a green light.

“This ‘head start’ provides pedestrian priority and improves pedestrian visibility by establishing a presence in the crosswalk before turning vehicles start moving,” says DDOT in the press release. The agency adds that lead pedestrian intervals are shown to reduce the number of pedestrians hit by vehicles at the intersections where they’re implemented.
