Uber Advanced Technologies Group has officially resumed on-road testing of its self-driving vehicles in Pittsburgh, nine months after the company halted its entire autonomous vehicle operation after one of its vehicles struck and killed pedestrian Elaine Herzberg in the Phoenix suburb of Tempe.

The relaunch follows the Pennsylvania Department of Transportation decision to authorize Uber ATG to put its autonomous vehicles on public roads.
