Wallace Loggins, 36, is scheduled to be arraigned Friday in connection with the death of 23-year-old Emily Dunn, who was struck while walking in a crosswalk at 18th and Hartford streets on Aug. 19.
Loggins was turning left onto Hartford Street when he struck Dunn, who was about 90 percent of the way across the street when she was hit, according to police.
Prosecutors said Loggins was unaware that he had hit someone until he heard a bystander scream.
"The evidence we have indicates Mr. Loggins was negligent while operating a Muni coach, resulting in the tragic death," district attorney's office spokesman Omid Talai said.
Loggins is not suspected of being under the influence of alcohol or drugs at the time of the accident.
Muni spokesman Paul Rose did not immediately respond to a request this morning for more information on the incident and Loggins' employment status.
