New self-driving car testing ground, the $135 million American Center for Mobility, is now open for business.

Located in Ypsilanti, Mich, the first inaugural test runs have belonged to Toyota and Visteon, an auto electronics and connected car solutions supplier. Both started testing this week. Research will include a deep dive into DriveCore, Visteon’s artificial intelligence-based autonomous driving platform with Level 3 capability. Other areas of testing include but are not limited to sensor technology and vehicle-to-infrastructure projects.

The American Center for Mobility, a collaboration between the State of Michigan and various Michigan-based transportation and economic organizations, is a 500-acre facility funded by AT&T, Toyota, Ford, Gundai, and Visteo.

Other automakers and partners are expected to follow suit next week.

“We are excited to be open for testing and to have our Founders already leveraging the assets of this facility,” said John Maddox, president, and CEO of the American Center for Mobility. “We have been moving rapidly, and along with good input from our founders, a great deal of work has gone into developing this site. Opening our doors is just the beginning as we continue to develop the American Center for Mobility into a global hub for CAV and future mobility technologies to put self-driving cars on America’s roads safely.”

The facility will focus on the development of connected and autonomous vehicle testing using simulated environments. Among them is a 2.5-mile highway loop, double overpassed, roundabouts, intersections, and others. To date, more than $100 million of investments have been secured with private ones expected at a later time.

Activity has also seen the American Center for Mobility partner with 15 Michigan-based universities and community colleges in helping train and provide recruitment opportunities for workers who can become displaced by mobility technology, such as taxi and delivery drivers. At the moment, participation is limited to Michigan schools.

Ann Arbor, Mich. and surrounding areas have quickly grown as a hotbed for autonomous vehicle testing. Another self-driving vehicle testing ground, the 32-acre M-City, located on the University of Michigan’s North Campus Research Complex, is situated 10 miles away.

Opened in the summer of 2015, that site also saw a consortium of financiers such as Ford and Honda make millions of dollars worth of contributions to acquire first use of the facility, which is considered the American Center for Mobility’s “sister city.”
