Third pedestrian death downtown within a month

A 79yearold woman died Saturday night after being struck by a car at Fifth and Market streets in San Francisco, authorities said, marking the third pedestrian death downtown in less than a month.

Officers responded to reports of the incident at 8:50 p.m. and found Hui Jun Yang of San Francisco in the street, according to the San Francisco medical examiner’s office. She died at the scene.

The driver stopped and cooperated with police. Neither alcohol nor drugs appear to be factors in the collision, police said.

It was the 14th fatal crash this year in San Francisco involving a pedestrian and the third in a fourblock stretch in less than a month.

On July 18, a tractortrailer fatally struck 50yearold Michael Evans of San Francisco near Eddy and Mason streets, close to the Powell Street BART station. The driver fled and was detained near the Embarcadero, police said. Officials have not said whether the driver will be charged.

Three days later, police said, a 21yearold woman drove a Tesla through a red light and hit a couple walking in a crosswalk at Taylor and O’Farrell streets, killing the husband, 39yearold Benjamin Dean of Clovis (Fresno County). The driver, Kelsey Cambridge of Vallejo, was charged with vehicular manslaughter.

Taylor Street between Market and Sutter streets has been identified as one of the city’s most dangerous corridors. From 2011 to 2016 there were 109 crashes there, 69 of which involved pedestrians or bicyclists, according to the San Francisco Municipal Transportation Agency.

The intersection of Fifth and Market is one of the most dangerous in the city for pedestrians, according to Vision Zero SF, the city’s pedestrian safety initiative.

Supervisor Matt Haney, whose district includes the South of Market and Tenderloin neighborhoods, tweeted a photo of the collision scene Saturday night.

“Too many cars. Too fast. Too many turns,” he wrote. “It’s f—ing infuriating and deadly.”

He said pedestrians need to be given more time to cross the street and further protections against cars turning into crosswalks.
