The company plans to restart testing in Pittsburgh after federal agencies have concluded their investigations.
Uber has decided to shutter its autonomous car testing program in Arizona.
The decision comes months after one of the company's prototype cars struck and killed a pedestrian in Tempe. Neither the autonomous system nor the human safety driver reacted in time to prevent the accident.
Uber has temporarily halted all autonomous testing since the accident. The program will be restarted after federal agencies complete their investigations, but initially only in Pittsburgh. The company is also in talks with regulators in California, according to The Republic.
"We're committed to self-driving technology, and we look forward to returning to public roads in the near future," the company said in a statement. "In the meantime, we remain focused on our top-to-bottom safety review, having brought on former NTSB Chair Christopher Hart to advise us on our overall safety culture."
No detailed explanation has been given for the decision to shut down its Arizona operations, which hosted around 300 workers.
