Research on autonomous driving technology and vehicles is taking place throughout America, and the technology is primed to transform existing and future transportation systems. As the technology for autonomous vehicles continues to develop and eventually becomes ready for real-world testing, cooperative automation can improve the efficiency and safety of these vehicles within the transportation system. Cooperative driving automation (CDA) supports and enables communication between vehicles with driving automation features, other road users, and transportation infrastructure. Once deployed, CDA has the potential to improve transportation efficiency, facilitate freight movement, increase productivity, and save billions by reducing the need to increase roadway facilities. Most importantly, CDA has the potential to reduce crashes caused by human error and save lives.127
