GoMentum Station

{{Short description|Connected- and autonomous-vehicle testing ground}}

GoMentum Station is a testing ground for connected and autonomous vehicles at the former Concord Naval Weapons Station (CNWS) in Concord, California, United States. The property was acquired and repurposed by the Contra Costa Transportation Authority.

In October 2014, the Contra Costa Transportation Authority announced that the GoMentum Station proving grounds would be used to test self-driving cars; according to them, "The public will not have access to the test site, and the self-driving cars will be restricted to the test bed site. With {{convert|2100|acres}} of testing area and {{convert|19.6|mi}} of paved roadway, the CNWS is currently the largest secure test bed site in the United States".{{cite press release|url=http://www.ccta.net/about/download/PRESS%20RELEASE%20-%20Self-Driving%20Cars%20Headed%20to%20Contra%20Costa%20-%2010%2001%2014.pdf|title=Self-Driving Cars Headed to Contra Costa|publisher=Contra Costa Transportation Authority|date=October 1, 2014|access-date=August 15, 2015|archive-url=https://web.archive.org/web/20141031175405/http://www.ccta.net/about/download/PRESS%20RELEASE%20-%20Self-Driving%20Cars%20Headed%20to%20Contra%20Costa%20-%2010%2001%2014.pdf|archive-date=October 31, 2014|url-status=dead}} Mercedes-Benz is reported to have licenses to test new driving technology, including smart infrastructure such as traffic signals that communicate with cars.{{fact|date=August 2015}} Among the site's other notable features: "a {{convert|7|mi|adj=on}}-long roadway is great for testing high-speed driving, and a pair of {{convert|1400|ft|adj=on}}-long tunnels" for sensor testing.{{Cite magazine|url=https://time.com/4012989/driverless-cars-gomentum/|title=Here's Where Driverless Cars Are Learning the Rules of the Road|magazine=Time}}

Among the roughly 30 partners listed on the company's site are automakers Toyota and Honda, ridesharing companies Uber and Lyft and China-based autonomous driving company Baidu. In summer 2015, reports suggested the Apple electric car project was interested in using the site, as members of Apple's Special Project group were reported to have met GoMentum representatives but there were no subsequent reports of Apple personnel and vehicles actually using the site.{{cite web|url=http://fortune.com/2015/08/15/apple-auto-gomentum-station/|title=Here's the autonomous vehicle test bed Apple asked to see|author=Philip Elmer-DeWitt|date=15 August 2015|publisher=Fortune}}{{cite news|url=https://www.theguardian.com/technology/2015/aug/14/apple-self-driving-car-project-titan-sooner-than-expected|title=Documents confirm Apple is building self-driving car|last1=Harris|first1=Mark|date=August 14, 2015|work=The Guardian}}
