DETROIT (AP) — Nearly eight months after one of its autonomous test vehicles hit and killed an Arizona pedestrian, Uber wants to resume testing on public roads.
The company has filed an application on with the Pennsylvania Department of Transportation to test in Pittsburgh, and it has issued a lengthy safety report pledging to put two human backup drivers in each vehicle and take a raft of other precautions to make the vehicles safe.
Company officials acknowledge they have a long way to go to regain public trust after the March 18 crash in Tempe, Arizona, that killed Elaine Herzberg, 49, as she crossed a darkened road outside the lines of a crosswalk.
Police said Uber's backup driver in the autonomous Volvo SUV was streaming the television show "The Voice" on her phone and looking downward before the crash. The National Transportation Safety Board said the autonomous driving system on the Volvo spotted Herzberg about six seconds before hitting her, but did not stop because the system used to automatically apply brakes in potentially dangerous situations had been disabled. A Volvo emergency braking system also had been turned off.
"Our goal is to really work to regain that trust and to work to help move the entire industry forward," Noah Zych, Uber's head of system safety for self-driving cars, said in an interview. "We think the right thing to do is to be open and transparent about the things that we are doing."
Among the other precautions Uber will take are keeping the autonomous vehicle system engaged at all times and activating the Volvo's automatic emergency braking system as a backup.
In addition, Uber is requiring more technical training and expertise of employees sitting behind the wheel of the vehicles, according to a 70-page safety report the company released Friday.
The report comes after the ride-hailing company shut down autonomous vehicle testing to do an internal review of its safety procedures, as well as an outside review by risk management firm LeClairRyan.
Pennsylvania law at present does not allow testing of autonomous vehicles without human backup drivers. Google's Waymo already is carrying passengers in the Phoenix area without human drivers, and General Motors' Cruise Automation expects to do that next year.
Under Pennsylvania's voluntary autonomous guidelines, the Transportation Department has until Nov. 13 to approve or deny Uber's application, or to ask further questions.
The city of Pittsburgh can't legally prevent testing, but is in safety talks with Uber and four other entities that have permits to test autonomous vehicles, said Karina Ricks, Pittsburgh's director of the Department of Mobility and Infrastructure.
For instance, the city wants to limit self-driving vehicle speeds to 25 miles per hour in urban settings, even if the posted speed is higher.
"Lower rates of speed give more time for the vehicle and the safety driver to react and prevent a crash," said Ricks, who characterized the talks as fruitful.
Uber said it is focused on restarting tests in Pittsburgh, where it has an autonomous vehicle development center. Later it will discuss resumption in Arizona, California and Toronto, Ontario, its other test sites. Arizona suspended the company's permission to test after the crash.
Herzberg's death was the first involving a fully autonomous vehicle, raising questions about the safety of computer-controlled cars being built by Uber and dozens of other companies.
