On Saturday morning, a 39-year-old man struck a 60-year-old man with a sedan at 16th and De Haro streets, police said Monday.

The pedestrian was struck while crossing the road in the crosswalk at 8:48 a.m. Officials said he suffered a traumatic brain injury and is in critical condition at San Francisco General Hospital. The driver was not arrested, police said.

Just last Thursday, a 69-year-old female pedestrian was struck and killed by a truck driver just a seven-minute drive away from Saturday's crash, near 19th Street and South Van Ness Avenue. The woman was transported to the hospital with life-threatening injuries, where she later died, an SFPD spokesperson said. Bay City News reports that the woman was identified by the SF Medical Examiner's office as Pilsoo Seong of San Francisco. 

Last year, 23 people died on city streets, and as of August 31, the 2019 death toll from traffic fatalities in San Francisco was 22 people. That number doesn't include Seong or other pedestrians who were killed in September and October. 

Large parts of 16th Street are part of the city’s high-injury corridors, the 13% of streets where 75% of traffic crashes occur, but the intersection of 16th and De Haro streets is not. San Francisco's Vision Zero program aims to end all traffic fatalities on city streets by 2024, but the city is struggling to meet that goal. 

Last week, Walk SF executive director Jodie Medeiros said in a statement that "lives are being lost all too frequently, and devastating families and our communities."

Update, November 8: On Friday, Walk SF announced that the victim succumbed to his injuries in the hospital. 

The death marks the 17th person killed while walking or biking in San Francisco this year. Pilsoo Seong, who was struck and killed by a truck driver in the Mission last week, was the 16th.

"We grieve yet another life lost to traffic violence," said Jodie Medeiros, executive director of Walk SF. "We hold the loved ones of the victim close in our thoughts."

This week, the Board of Supervisors declared a state of emergency on pedestrian and cyclist fatalities in San Francisco. However, the declaration is largely ceremonial, and does not force the SFMTA to prioritize changes like reducing and enforcing speed limits or adding red-light cameras.
