Two /*Muni*/ buses were involved in an accident just last month in Chinatown.
From April through June, Muni vehicles had a rate of about six accidents for every 100,000 miles.
That's a 6 percent increase from the previous quarter, and a 27 percent increase from the final quarter of last year.
It's also the first time since last year that the accident rate has exceeded Muni's benchmark for collisions.
