How Connectivity: CV, CAV, and V2X affects Transportation Systems Operations (and Efficiency)

Connected vehicles (CVs), connected autonomous vehicles (CAVs), and Vehicle-to-Everything (V2X) technologies can improve transportation system operations and efficiency. For example, Guler et. al [1] used simulations to assess the potential for CVs to optimize intersection efficiency, finding that CVs could reduce delays by up to 60 percent. The reductions in intersection delays were up to 7 percent greater for CAVs compared to CVs controlled by drivers [1]. Platooning technology can reduce fuel consumption and smooth traffic oscillation [2], and there is a growing body of research around autonomous intersection management [3], [3], [4], [5]. Vehicle to infrastructure (V2I) technology can also improve traffic efficiency by optimizing traffic signal control [6].

A significant body of research exists on how to optimize traffic and safety using connective technology, but it is primarily based on simulations since real-world data is limited [1].
