Ann Arbor Connected Vehicle Test Environment (AACVTE)

Since 2011, thousands of vehicles have been participating in a large-scale test of connected vehicle technologies in Ann Arbor.  US DOT has sponsored two research programs in Ann Arbor; Safety Pilot Model Deployment (SPMD) and the Ann Arbor Connected Vehicle Test Environment (AACVTE).  Currently, there are about 1,300 vehicles participating.  These vehicles are communicating with each other and with select intersections by broadcasting their latitude and longitude coordinates, heading and speed at ten times per second.  Additionally, 25 intersections are also equipped with communication devices.

After extensive changes to the standards and security protocols that govern dedicated short-range communication (DSRC), AACVTE’s suppliers will begin delivering new vehicle awareness devices (VADs) and after safety market devices (ASDs) in May. Further, 49 intersections will be equipped expanding the infrastructure footprint to include all of Ann Arbor. While the VADs are transmitting devices, the ASDs will run applications and provide drivers with several different types of warnings via a speaker and a light bar. Beginning in early May, we will be replacing existing hardware in current participants’ vehicles as well as recruiting additional drivers to participate in AACVTE.  Drivers who have a VAD or an ASD installed in their vehicles will be paid $40.
