Collisions and Injuries

According to SFPD records, from 1999 to 2003 between San Jose at Randall and Guerrero at Cesar Chavez, there were:

  • 105 collisions
  • 101 injuries
  • 11 injuries to pedestrians or bicyclists (3 "hit and run")

Many collisions are not reported to the police. The UC Berkeley Institute of Transportation Studies estimates that police data "underestimates pedestrian-injury collisions by at least 21.8 percent." (View source)

Speed and death

At 15 mph, the odds of a pedestrian surviving a collision are approximately 96%. But when a person is hit by a car traveling at 31 mph, the odds are significantly reduced. And at 45 mph the odds of survival are just 17%.

Car-Building Collisions

5 of the 9 houses on the west side of Guerrero just south of Cesar Chavez have had their facades and/or entry stairs destroyed by cars going out of control as they speed around the corner--some more than once.

Worse, a man was killed INSIDE his house when a car rammed into it at San Jose and Valley. Steel beams now protect the building (but will surely kill the next driver who hits it).
