NTSB Report On Fatal Uber Crash In Tempe Arizona
NTSB ^ | 05/24/2018 | NTSB

Posted on 05/24/2018 9:05:03 PM PDT by Moonman62

About 9:58 p.m., on Sunday, March 18, 2018, an Uber Technologies, Inc. test vehicle, based on a modified 2017 Volvo XC90 and operating with a self-driving system in computer control mode, struck a pedestrian on northbound Mill Avenue, in Tempe, Maricopa County, Arizona. The Uber test vehicle was occupied by one vehicle operator, a 44-year-old female. No passengers were in the vehicle.

In the area of the crash, northbound Mill Avenue consists of two left-turn lanes, two through lanes, and one bike lane. The crash occurred before the formation of a right-turn lane. Roadway lighting was present. The posted speed limit was 45 mph.

The crash occurred as the pedestrian, a 49-year-old female, walked a bicycle east across Mill Avenue. The Uber test vehicle was traveling in the right through lane when its right front side struck the pedestrian (see figure 1). As a result of the crash, the pedestrian died. The vehicle operator was not injured.

In this area, northbound Mill Avenue is separated from southbound Mill Avenue by a center median containing trees, shrubs, and brick landscaping in the shape of an X. Four signs at the edges of the brick median, facing toward the roadway, warn pedestrians to use the crosswalk. The nearest crosswalk is at the intersection of Mill Avenue and Curry Road, about 360 feet north of where the crash occurred.

Uber had equipped the test vehicle with a developmental self-driving system. The system consisted of forward- and side-facing cameras, radars, LIDAR, navigation sensors, and a computing and data storage unit integrated into the vehicle.[1] Uber had also equipped the vehicle with an aftermarket camera system that was mounted in the windshield and rear window and that provided additional front and rear videos, along with an inward-facing view of the vehicle operator. In total, 10 camera views were recorded over the course of the entire trip.

The self-driving system relies on an underlying map that establishes speed limits and permissible lanes of travel. The system has two distinct control modes: computer control and manual control. The operator can engage computer control by first enabling, then engaging the system in a sequence similar to activating cruise control. The operator can transition from computer control to manual control by providing input to the steering wheel, brake pedal, accelerator pedal, a disengage button, or a disable button.

The vehicle was factory equipped with several advanced driver assistance functions by Volvo Cars, the original manufacturer. The systems included a collision avoidance function with automatic emergency braking, known as City Safety, as well as functions for detecting driver alertness and road sign information. All these Volvo functions are disabled when the test vehicle is operated in computer control but are operational when the vehicle is operated in manual control.

According to Uber, the developmental self-driving system relies on an attentive operator to intervene if the system fails to perform appropriately during testing. In addition, the operator is responsible for monitoring diagnostic messages that appear on an interface in the center stack of the vehicle dash and tagging events of interest for subsequent review.

On the night of the crash, the operator departed Uber’s garage with the vehicle at 9:14 p.m. to run an established test route. At the time of the crash, the vehicle was traveling on its second loop of the test route and had been in computer control since 9:39 p.m. (i.e., for the preceding 19 minutes).

According to data obtained from the self-driving system, the system first registered radar and LIDAR observations of the pedestrian about 6 seconds before impact, when the vehicle was traveling at 43 mph. As the vehicle and pedestrian paths converged, the self-driving system software classified the pedestrian as an unknown object, as a vehicle, and then as a bicycle with varying expectations of future travel path. At 1.3 seconds before impact, the self-driving system determined that an emergency braking maneuver was needed to mitigate a collision (see figure 2).[2] According to Uber, emergency braking maneuvers are not enabled while the vehicle is under computer control, to reduce the potential for erratic vehicle behavior. The vehicle operator is relied on to intervene and take action. The system is not designed to alert the operator.

The self-driving system data showed that the vehicle operator intervened less than a second before impact by engaging the steering wheel. The vehicle speed at impact was 39 mph. The operator began braking less than a second after the impact. The data also showed that all aspects of the self-driving system were operating normally at the time of the crash, and that there were no faults or diagnostic messages.

Several Uber self-driving system cameras captured the crash event. The videos were reviewed by the NTSB and the parties to the investigation. The forward-facing videos show the pedestrian coming into view and proceeding into the path of the vehicle. The videos also show that the pedestrian, once visible, did not look in the direction of the vehicle until just before impact. The videos show that the pedestrian was dressed in dark clothing and that the bicycle did not have any side reflectors. The bicycle had front and rear reflectors and a forward headlamp, but all were facing in directions perpendicular to the path of the oncoming vehicle. The videos show that the pedestrian crossed in a section of roadway not directly illuminated by the roadway lighting.

The inward-facing video shows the vehicle operator glancing down toward the center of the vehicle several times before the crash. In a postcrash interview with NTSB investigators, the vehicle operator stated that she had been monitoring the self-driving system interface. The operator further stated that although her personal and business phones were in the vehicle, neither was in use until after the crash, when she called 911.

The NTSB continues to gather information on the Uber self-driving system, the vehicle interface, and the driver’s personal and business cell phones. Although toxicological specimens were not collected from the vehicle operator, responding officers from the Tempe Police Department stated that the vehicle operator showed no signs of impairment at the time of the crash.

The NTSB continues to gather information on the pedestrian and is seeking information from anyone who might be aware of her activities before the crash. Those with information should contact the NTSB by email at witness@ntsb.gov. Toxicology test results for the pedestrian were positive for methamphetamine and marijuana.

All aspects of the crash remain under investigation as the NTSB determines the probable cause, with the intent of issuing safety recommendations to prevent similar crashes. The NTSB is working with the parties to the investigation—Uber, Volvo Cars, and the Arizona Department of Transportation—to compile a complete and accurate account of the crash.

Anyone looking at the poor quality video (and the actual video was better) would instantly recognize a woman walking a bike. The object recognition is not ready for the real world and probably won't be for another decade or two.

The radar and LIDAR sound pretty useful for anticipating pedestrians and cyclists. Not sure if the display actually showed the driver that someone was approaching, though, even though the sensors appeared to have detected her 6 seconds before impact.

The deep state is determined to push this technology regardless of the number of casualties.

They want to make it illegal for human beings to drive ordinary passenger cars.

Driving a passenger car on public roads is a privilege, not a right protected by the Constitution.

Simple. Look both ways before crossing the street.

Also, it seems that a collision with anything should have been grounds for an avoidance and braking. I cannot guess why software engineers would want a system under development to not activate emergency procedures in the event of an eminent collision. The concept of avoiding erratic driving does not really make sense, since the software would in theory make the best of the situation.

Or else as you post, the system is not ready for prime time. In which case why would it be tested on actual roads? With actual pedestrians with bicycles?

It’s not. That’s why there was a safety driver and the emergency braking was disabled. It does seem that an audible alert would have been helpful, though.

And don’t cross the road where there are signs saying not to cross the road.

There’s no market demand for driverless other than from the CIA assassins’ guild.

" I cannot guess why software engineers would want a system under development to not activate emergency procedures in the event of an eminent collision."

I think it is because the cameras will see a shadow, slam on the brakes and cause many accidents. Instead they are relying on accurate object detection, which doesn't exist (yet), and stopping for known objects.

I was wondering what was up with this ‘self driving cars’ rubbish. It was astonishing, to me, that people had become so lazy that they don’t even want to drive their own cars anymore. All the money being pissed away on this foolishness could certainly be put to better use.

Or don’t cross any streets that have deadly driverless cars on them.

Then let the cars finance and build their own highways and streets.

Almost 40,000 people die in traffic accidents every year in the United States.

The idea is that eventually self driving cars, or cars with some type of autopilot will be much safer.

all this tells me self driving cars at this point are pretty stupid and really require a person driving it.

That woman was also drunk (and an ex-con for numerous thefts and drug crimes) who did not once look to see if a car was coming, despite walking across a busy road away from a crosswalk and away from overhead lights.

And in SIX SECONDS did nothing to avoid killing the woman. The driver was busy was readouts instead of the road. Park these cars!

They keep getting better, and Waymo has some cars now that have no safety driver.
