Han Cheng Li, 62, Killed by Driver at 16th and Potrero

Han Cheng Li, 62, was struck and killed by a driver on 16th Street at Potrero Avenue in the Mission at about 11:38 p.m. Saturday night, according to reports. Police have not released details about how the crash occurred or the name of the driver, but he has been identified as a 54-year-old man. Li is the 12th pedestrian to be killed in traffic in San Francisco this year.

Nicole Schneider, executive director of Walk SF, pointed out that between 2005 and 2010, five pedestrians were injured at 16th and Potrero, about one per year. “We are deeply sorry for Han Cheng Li’s family and friends,” she said. “While we still don’t know how the collision occurred, each of these deaths are preventable.”

Sixteenth and Potrero both have four traffic lanes and few measures in place to tame driving speeds. Although a plan to redesign a section of Potrero is in the works, it would only encompass the stretch south of 17th Street. On 16th Street, the Muni Transit Effectiveness Project calls for two traffic lanes to be converted to center-running bus lanes — which could have the added benefit of calming motor traffic — but that project is several years away from implementation.

“We know that a pedestrian hit by a car traveling 40 mph has a 30 percent chance of surviving, but by reducing speed to 30 mph, that chance of survival goes up to 80 percent,” said Schneider. “The city has the tools needed to calm traffic on our streets, and we want to see those tools implemented before any additional families have to suffer the loss of a loved one.”
