Ann Arbor Connected Vehicle Test Environment (AACVTE) is the world’s largest operational, real-world deployment of connected vehicles and connected infrastructure, built on the existing Ann Arbor Safety Pilot Model Deployment (SPMD) project at University of Michigan. Over 2,500 vehicles (e.g., passenger vehicles, buses, and trucks) are equipped with CV devices including
passenger vehicles, commercial trucks, and buses. The vehicles are equipped with one of the two types of DSRC on-board units: aftermarket safety device (ASD) or vehicle awareness device (VAD). The aftermath safety devices (ASDs) enable V2V communication for safety applications, including forward collision warning (FCW) and intersection movement assist (IMA), among others. The vehicle awareness devices (VADs) simply transmit the basic safety message (BSM) to seed the environment with connected vehicles to maximize interactions for optimal technology and application development. In addition to the ASD or VAD, the vehicles are equipped with a global navigation satellite system (GNSS) antenna and a DSRC antenna.
Furthermore, the SPMD infrastructure footprint has grown from 25 sites to over 70 infrastructure locations equipped with RSUs. The RSUs located at the 60 intersections are connected to the traffic signal controllers and broadcast SPaT messages and MAP messages to support infrastructure-related applications such as red light violation warning (RLVW) and curve speed warning (CSW). All vehicle and infrastructure communications follow national and international standards including SAE J2735, SAE J2945, IEEE 1609.2, and IEEE 1609.3, with production security certificates to ensure security and privacy.
