Aptiv releases massive self-driving car data set, aiming to boost safety research

In an effort to spur greater research into self-driving car safety, automotive tech firm Aptiv is releasing a massive data set to the public. Called NuScenes by Aptiv, it’s made up of sensor data from Aptiv self-driving cars harvested during testing on public roads. Aptiv claims it is the largest data set of its kind to be made available to the public.

“We appreciate the importance of transparency and building trust in AVs [autonomous vehicles],” Karl Iagnemma, president of Aptiv Autonomous Mobility, said in a statement. The kind of data being released “has traditionally been kept confidential with academic communities, cities, and the public at large,” he said.

The NuScenes by Aptiv data set includes 1.4 million images, 390,000 lidar sweeps, and 1.4 million 3D “human annotated bounding boxes,” according to Aptiv. The data is organized into 1,000 “scenes” representing real-life driving scenarios from the streets of Boston and Singapore, the company said. To date, over 1,000 users and 200 academic institutions have registered for access to the data set, according to Aptiv.

The fact that data comes from Boston and Singapore indicates it was collected by NuTonomy, an autonomous-driving tech startup bought by Aptiv predecessor Delphi in 2017. NuTonomy launched a pilot autonomous-taxi service in Singapore in 2016, and also worked with Lyft on an autonomous ride-sharing pilot in Boston, its hometown. A novel point of the Boston pilot is that it uses modified Renault Zoe electric cars — a model not sold in the United States. The French cars were originally confined to a small area of Boston’s waterfront, but are now free to roam throughout the city.

Aptiv was originally the automotive supplier Delphi, but in 2017 the company reorganized itself to focus on autonomous-driving tech. In addition to the test programs that originated with, NuTonomy Aptiv operates a fleet of modified BMW 5 Series sedans in Las Vegas. You can even hail one using the Lyft app.

Self-driving car safety continues to be a controversial issue roughly one year after an Uber test vehicle struck and killed a pedestrian in Tempe, Arizona. The first known fatality involving a self-driving car, it highlighted issues with the technology, but did not appreciably slow its deployment. While many Americans appear uneasy about autonomous cars hitting the road, companies are pushing ahead with new and expanded test programs.

Tesla issues stark warning to drivers using its Full Self-Driving mode
A Telsa Model 3 drives along a road.

Tesla in recent days rolled out a long-awaited update to its Full Self-Driving (FSD) mode that gives its vehicles a slew of driver-assist features.

But in a stark warning to owners who’ve forked out for the premium FSD feature, Tesla said that the software is still in beta and therefore “may do the wrong thing at the worst time.” It insisted that drivers should keep their "hands on the wheel and pay extra attention to the road.”

The future of transportation: Self-driving cars? Try self-driving everything
GM electric flying taxi

Technology is reshaping every aspect of our lives. Once a week in The Future Of, we examine innovations in important fields, from farming to transportation, and what they will mean in the years and decades to come. 

Stroll around any CES (virtual or otherwise) in the last decade and it’s impossible to miss all the feels the tech industry has for transportation, self-driving cars in particular. Every major technology company has its fingers in cars, from the infotainment systems powered by Google and Apple to the operating systems driven by Blackberry and Linux to the components and circuits that make up the car itself, built by Qualcomm and Nvidia and NXP and a dozen more. (And don't get me started about this Apple Car nonsense.)

From Paris to NYC, Mobileye will bring self-driving cars to metropolises

A Tesla in Autopilot mode can ply the highways of Northern California without issue, but when it comes to congested cities packed with erratic vehicle traffic, bikes, and pedestrians, cameras don’t always cut it. Or they didn’t, anyway. After years of testing, Intel-owned Mobileye intends to embrace the madness of the metropolis by rolling out self-driving cars in cities across the world.

On Monday, the first day of CES 2021, the company announced that Tokyo, Shanghai, Paris, Detroit, and New York City will all see fleets of Mobileye-powered vehicles rolled out in early 2021, if all goes well (regulatory issues are still being ironed out in NYC).
