Uber asks to test driverless cars 8 months after death

Nearly eight months after DETROIT 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 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, Ariz., 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.

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.
