About self-driving car saw pedestrians 6 seconds before the crash, says NTSB



The National Road Safety Council has released a preliminary report on Uber's deadly pedestrian collision in Tempe Arizona, and the first results do not seem to please anyone.

The preliminary report, which contains no probable cause and is still subject to future adjustments, indicates that the pedestrian involved in the accident wore dark clothing in a poorly lit section of the street while carrying a bicycle without side reflectors. The victim was tested positive for both marijuana and methamphetamine after the collision.

Regarding Uber's self-propelled Volvo XC90 the report confirms that Uber disables Volvo's built-in driver assistance systems, including autonomous emergency braking when operating in autonomous mode. However, while Uber's system has its own Autobrake capabilities, this system is also disabled during autonomous operation to reduce the potential for unpredictable vehicle behavior.

According to data from Uber's system, the pedestrian was first detected about 6 seconds before the crash. The software of the system first recognized the pedestrian as an unknown object, then as a vehicle and finally as a bicycle. Then, 1

.3 seconds before the accident, the braking system was needed to avoid an accident, but since Uber's autobrake was disabled, it was up to the human driver to apply the brakes. Despite the fact that it is the operator, the report states that the system is "not designed to warn the operator".

Eventually, the driver grabbed the steering wheel and tried to apply the brakes less than a second before the impact. She told the NTSB that she "monitors the self-propelled interface before the crash," but if there are no warnings to stop the driver, it makes sense that she only tried after she noticed the pedestrian on the road Has.

"Over the last two months, we have worked closely with the NTSB," said a Uber spokesperson in an e-mail statement. "As their investigation continues, we have launched our own safety review of our self-driving vehicle program, and have also brought former NTSB Chairman Christopher Hart to discuss our overall safety culture, and we look forward to hearing more about The Changes which we will undertake in the coming weeks. "

The investigation is ongoing, so the NTSB may have more data in the future. Meanwhile, Uber has completely stopped its autonomous operations in Arizona saying it will instead focus on tests in Pennsylvania.
