Waymo Robotaxis Expand to Freeways in LA, SF & Phoenix

Waymo Expands Robotaxi Service to Include Freeways

Sixteen years ago, the initial autonomous vehicle trials for what would become the Google self-driving project were conducted on the freeway linking Silicon Valley and San Francisco.

The project subsequently evolved into Waymo, and autonomous vehicle testing broadened, extending to numerous other cities.

Commercial robotaxi services were ultimately launched by the company in Phoenix, San Francisco, and Los Angeles, with further cities joining the network.

Freeway Access: A Significant Milestone

Despite early freeway testing, these high-speed routes remained inaccessible for regular service. This changes now.

Waymo announced on Wednesday the commencement of robotaxi rides incorporating freeway usage across San Francisco, Phoenix, and Los Angeles.

This represents a crucial expansion for the company, projected to reduce ride durations by as much as 50%.

This improvement in travel time is anticipated to attract a wider user base, particularly those needing to commute between towns and suburbs within the San Francisco Bay Area, or across the extensive Los Angeles and Phoenix metropolitan regions.

Essential for Airport Connectivity

Freeway access is also vital for Waymo to facilitate rides to and from San Francisco Airport, a location currently undergoing testing.

Phased Rollout and Service Area Expansion

Initially, the service will not be universally available to all Waymo users.

Riders interested in experiencing freeway rides can indicate their preference within the Waymo application.

Upon requesting a ride, users may then be matched with a trip that includes freeway segments, as per the company’s statement.

The company’s service area will now extend to San Jose, creating a comprehensive 260-mile operational zone across the Peninsula.

Furthermore, Waymo will introduce curbside pickup and drop-off services at San Jose Mineta International Airport, complementing the existing curbside service offered at Sky Harbor Phoenix International Airport.

Challenges of Autonomous Freeway Driving

“Mastering freeway driving for full autonomy, without a human driver as backup, and at scale, presents a unique challenge,” stated Waymo co-CEO Dmitri Dolgov during a media briefing.

“It required a deliberate and thorough approach, prioritizing system safety and reliability.”

Waymo robotaxis have been observed on freeways for several months, including a TechCrunch test ride in the Phoenix area last year.

Employee trips incorporating freeways have been conducted for over a year, alongside expanded testing utilizing closed courses and simulations.

Addressing Rare Scenarios

While often perceived as simpler, freeway driving introduces specific complexities, according to principal software engineer Pierre Kreitmann.

He explained that critical events occur less frequently on freeways, resulting in fewer opportunities to expose the self-driving system to uncommon situations and validate its performance under pressure.

To address this, the company supplemented real-world driving with extensive closed-course and simulation testing.

Ensuring Safe Transitions and Operational Protocols

This expanded testing and validation process was implemented to guarantee seamless and secure transitions between freeways and surface streets.

It also ensures the vehicles can accurately recognize and adapt to the surrounding road conditions.

Waymo has also refined its operational protocols, including enhanced coordination with safety authorities like the California Highway Patrol, now that its robotaxis operate on freeways.
