The first open-source digital twin of the Mcity Test Facility\u2014the University of Michigan’s test center for connected and autonomous vehicles and technologies\u2014is now available to the public, giving researchers around the world a new free tool.<\/p>\n

A digital twin is a virtual representation of a physical environment that also exchanges data with that environment, enabling simulation and testing. The new Mcity digital twin is the first open-source digital twin for mobility systems testing, including autonomous driving. It provides a faster, safer, less expensive way to test autonomous and connected vehicle software.<\/p>\n

Researchers anywhere can use the facility’s features\u2014with a variety of road materials, markings, signals and intersections\u2014to test their autonomous algorithms without having to make the trip to Ann Arbor.<\/p>\n

“This takes our almost 10-year-old track and puts the digital replica directly over it,” said Greg Stevens, Mcity’s director of research. “That’s a living, breathing manifestation of that physical track where people can do mixed reality testing and development.”<\/p>\n

The digital twin works with TeraSim<\/a>, an open-source traffic simulator developed by Mcity researchers. It introduces other road users, such as pedestrians, cyclists and other drivers, and generates safety-critical events like potential collisions. Using traffic behavioral models calibrated with real-world data, it simulates both normal and high-risk driving scenarios.<\/p>\n

Mobility officials have touted AVs, along with connected vehicles and infrastructure, as a path to safer, more efficient and equitable transportation. Still, a great deal of research remains ahead before the technologies will produce everyday benefits for a large portion of the population. Testing in the real world takes time and money and creates a host of safety issues, but virtual testing can enable control software to demonstrate a high level of safety ahead of that stage.<\/p>\n

“You can drive millions of miles in your AV in a digital twin built off of a real-world environment before your AV actually touches the real world,” said Darian Hogue, an Mcity software engineer who helped develop the digital twin. “With this, we can control all kinds of factors. That includes controlling and manipulating simulated pedestrian traffic\u2014a factor that is random in the real world. This focuses and accelerates simulated testing.”<\/p>\n

Opened in 2015, the Mcity Test Facility is the world’s first purpose-built proving ground for connected and automated vehicles. Its physical features include:<\/p>\n
