SAN FRANCISCO — Uber Technologies is speeding ahead with plans for flying cars, which could zoom among urban centers such as Silicon Valley, San Francisco and Oakland, by hiring a NASA veteran who has presented research about the possibilities.

If it sounds like “The Jetsons” or the flying DeLorean in the “Back to the Future” movies, the comparison might be apt. Uber and others working in this new field call the flying cars “vertical take-off and landing aircraft,” or VTOL for short.

The new technologies are being touted as a way to ease the mammoth traffic jams that snarl busy employment hubs such as the Bay Area.

“Imagine traveling from San Francisco’s Marina to work in downtown San Jose — a drive that would normally occupy the better part of two hours — in only 15 minutes,” Jeff Holden, Uber’s chief product officer, stated in a post at Medium.com. “Every day, millions of hours are wasted on the road worldwide.”

San Francisco-based Uber, which is building a co-headquarters in Oakland, said Monday it has hired Mark Moore, chief technologist with the NASA Langley Research Center in Virginia.

“Uber continues to see its role as a catalyst to the growing and developing VTOL ecosystem,” said Nikhil Goel, Uber’s head of product for advanced programs, in confirming the hiring of Moore. “We’re excited to have Mark join us to work with companies and stakeholders as we continue to explore the use case described in our white paper.”

Still, such initiatives are primarily blue sky-type studying, rather than a world suddenly filled with flying vehicles overhead, analysts said.

“We are decades off from the reality of flying cars, but some companies are starting to do the research now,” said Ben Bajarin, an analyst with Campbell-based Creative Strategies, which tracks tech trends. “Good on Uber to start seeing how feasible this is.”

A flying vehicle would initially require a fee of $129 for a flight between San Francisco and San Jose, whereas an UberX trip might cost about $111 during commute travel times, Uber’s white paper said. But the trip duration up in the sky would be 15 minutes rather than approaching two hours, it said.

An array of helipads could be used as landing sites for the flying vehicles.

“Just as skyscrapers allowed cities to use limited land more efficiently, urban air transportation will use three-dimensional airspace to alleviate transportation congestion on the ground,” Uber stated in its white paper. “A network of small, electric aircraft that take off and land vertically will enable rapid, reliable transportation between suburbs and cities and, ultimately, within cities.”

The helipads could be on rooftops or in the middle of freeway cloverleafs. The white paper indicated that many such cloverleafs exist in metro areas such as Santa Clara County and nearby regions.

“On-demand aviation has the potential to radically improve urban mobility, giving people back time lost in their daily commutes,” Uber stated. “We view helping to solve this problem as core to our mission and our commitment to our rider base.”

In recent weeks, Elon Musk, chief executive officer of Palo Alto-based Tesla Motors, a maker of electric vehicles, said one option for Bay Area traffic woes might be to dig beneath the street surfaces that are packed with conventional automobiles and transit conveyances.

“The only options for expanding routes are down and up,” Bajarin said.

A 2015 NASA study determined that a metro center of roughly 47 square miles — by coincidence, San Francisco consists of 49 square miles — would require approximately 50 helipads. A large urban center such as the South Bay might require 200 helipads to cover 280 square miles.

Even Uber concedes that plenty of market barriers loom. Vehicle safety, the regulatory and permit process, battery technology, vehicle efficiency and performance, air-traffic control, noise and the availability of “vertiports” and charging stations are among the obstacles and challenges.

“We believe that in the long-term, VTOLs will be an affordable form of daily transportation for the masses, even less expensive than owning a car,” Uber stated in its white paper.
