UMTRI Reaches Year-End Goal for Connected Vehicle Installations

January 7, 2019

The University of Michigan Transportation Research Institute (UMTRI) reached its 2018 year-end target by equipping 2,200 connected vehicles and deploying 75 connected infrastructure sites in the Ann Arbor Connected Vehicle Test Environment (AACVTE).

To date, nearly $50M has been invested in Ann Arbor. AACVTE is the world’s largest combined vehicle and infrastructure connected environment and is the first commercial launch of connected vehicle technology.  Additionally, $3.4M has been secured through the University of Michigan’s Mcity to operate and maintain the environment for the next three years. Mcity also has sponsored deploying pedestrian detection (V2P) in the AACVTE, as well as contracting Green Hills to use its production security credential management system (SCMS).  The Green Hills’ SMCS is the cornerstone for interoperability with production vehicles that will be rolling off the assembly line from GM, Toyota, and others. 

In the context of vehicle safety systems, connected vehicles are those that communicate wirelessly with each and with the infrastructure, as opposed to vehicles that are connected to the internet. This communication is accomplished through dedicated short-range communications (DSRC) technology.  DSRC is ready for production and has the potential to eliminate 82% of all unimpaired accidents, saving over 30,000 lives each year and saving hundreds of millions of dollars in costs associated with vehicle crashes. In Ann Arbor, the AACVTE vehicles are equipped with both vehicle-to-vehicle (V2V) and vehicle to infrastructure (V2I) applications. The applications include forward collision warning, emergency electronic brake light, ice warning, pedestrian detection, emergency vehicle approach, intersection movement assist, curve speed warning, and red light violation.

“Ann Arbor is an international hub for connected vehicle technology and research. DSRC is ready for prime time, as demonstrated in AACVTE, and the sooner we get it on the roads, the sooner we can start to save lives,” said James R. Sayer, director UMTRI.

Additionally, UMTRI is spearheading efforts to make all of southeastern Michigan’s connected environments commercially interoperable.  This includes the City of Detroit’s ATCMTD project, Macomb County’s deployment of over 300 RSUs, MDOT’s deployment of thousands of RSUs along SE Michigan’s freeways and major arterials including I-69, I-75, I-94, I-96, I-275, I-696, M-10, M-59, and M-153, and Oakland counties Telegraph Road corridor.
