It looks like there's finally another transit agency willing to throw money at a similar concept to the U2C.
The Contra Costa Transportation Authority near San Francisco, California has
announced their plans to establish a 28-mile
system of dedicated guideways to operate 4-passenger autonomous shuttles built and operated by Glydways, the same company discussing plans to develop an airport connector in San Jose. A cost estimate for this system was not provided, with a timeline for implementation of "3 to 5 years".
Relevantly, the Executive Director of the CCTA, Tim Haile, appeared on the
first episode of the Autonomous Mobility
webinar hosted by JTA a few weeks ago.
