The National Transportation Safety Board (NTSB) has wrapped up more than a year of research in a slow collision between a self-driving shuttle and a delivery van in Las Vegas on November 8, 2017. The agency identified two possible suspicions for the accident: the truck driver's assumption that the shuttle would move to evade it, and that the safety officer in the shuttle did not have direct access to the manual override controls.
That the truck driver was somewhat blamed, immediately described the descriptions of the crash that occurred on the first working day of the shuttle. On that day, a Las Vegas government official described the truck that was moving the detained shuttle as it pulled back into an alley, which the NTSB eventually found in its investigation.
But the NTSB discovered that the safety operator in the shuttle and at least one of the eight passengers was aware that the truck was about to make contact. The problem was that the operator did not have direct access to the manual control buttons for the shuttle, which came in the form of an Xbox controller.
At the time of the crash, it was Operator Keolis' policy to store the controller in a storage compartment on the shuttle during journeys. If the operator had quick access to the controller, he could have moved the shuttle away from the truck, or at least triggered the horn to let the driver know that he was about to crash.
Instead, the nine people were left in the shuttle to watch the crash play in super slow motion. "Oh, he's going to hit you," said a passenger according to the NTSB report. The security operator slapped the window of the shuttle, waved his hands and called "stop", but to no avail. A few seconds later, the same passenger said, "Oh, he can't see this" and then the wheel of the truck pulled the left front corner of the shuttle.
The NTSB says that Keolis changed this policy after the crash and that the Xbox controller was easily available during the rest of the year-round pilot in Las Vegas during each subsequent trip.
The shuttle differently did the NTSB thought that the slower drive for the truck blocking its path and would have stopped if the operator had not pressed the emergency stop button. After all, it was a very simple route that only included four clockwise turns and one that was plotted and plotted before the test.
The operator said he "considered" to reach for manual operation, but ultimately did not believe he had enough time. "Things happened very quickly. Even though he was slowly backing up, a lot of things went through my mind," he told researchers. "(M) y main thought or my initial focus was I needed to get the shuttle stopped."
The truck driver, meanwhile, did see the shuttle coming. But he told the investigators that after seeing it coming to him, he thought it was a "reasonable assumption" that the shuttle would "stop a reasonable distance from a trailer for a trailer." So he turned away to watch an intersection pedestrian. When he made his next move, he scraped the shuttle.
"I thought the thing was under control," he told the researchers. "I thought they should have let the case work out; (that) it would work well. I thought someone could stop it if necessary. & # 39;
The pilot in Las Vegas, which was conducted in collaboration with AAA, was billed as the first such autonomous shuttle test in live traffic in the country. The shuttle is made by a company called Navya and is managed by Keolis. Since then, a number of different companies have offered similar pilots across the country.
