The Congestion Impacts Reduction via CAV-in-the-loop Lagrangian Energy Smoothing (CIRCLES) project aims to reduce instabilities in traffic flow, called "phantom jams," that cause congestion and wasted energy. If you have ever encountered a temporary traffic jam for no apparent reason, this might have been a phantom jam that occurred naturally because of human driving behavior.

The CIRCLES Consortium consists of 5 lead researchers and 35 scholars coming from diverse academic backgrounds. CIRCLES is led by UC Berkeley and the Institute of Transportation Studies (ITS) Berkeley, in coordination with Vanderbilt University, University of Arizona, Temple University, Rutgers University-Camden, the Tennessee Department of Transportation, Toyota North America, and General Motors. The project is backed primarily by DOE and NSF funding. It will also provide the opportunity for engagement with major automotive partners and federal agencies (e.g., DOE, DOT).
