(ONN) – A $45 million testing ground for self-driving vehicles has opened in Ohio.

The Transportation Research Center unveiled its 540-acre SMARTCenter on Wednesday.

The state-of-the-art automated and connected testing facility is located in East Liberty, about 40 miles northwest of Columbus.

The SMARTCenter features roads and structures intended to replicate the high-speed intersections, rural roads and urban areas normally encountered by drivers.

Officials say the facility is among the most advanced in North America.

The goal is to help researchers and developers improve the performance of self-driving vehicles.
