In response, Uber quickly halted its self-driving cars as the crash is under investigation.
According to The New York Times, the Uber vehicle was in autonomous mode with a human safety driver at the wheel when it struck the woman, who was crossing the street outside of a crosswalk, the Tempe police said in a statement.
It appears to be the first known death of a pedestrian struck by an autonomous vehicle on public roads.
A spokeswoman from Uber said that the company was "fully cooperating" with the local authorities.
The woman has not been publicly identified. (ANI)
