Office of Operations Research and DevelopmentTurner-Fairbank Highway Research CenterFederal Highway AdministrationThe Federal Highway Administration (FHWA) has led the research and development of innovative applications of connected automation which offer the potential of significant mobility, safety, and environmental benefits. One of the major challenges in testing and demonstrating the benefits of these innovative technologies is the small number of test vehicles available for experiments. This leads to a lack of CAV field data for the development of valid CAV modeling tools for State and local transportation agencies.One approach to overcoming these challenges is to use emerging HIL tools that allow real test vehicles to interact with virtual vehicles from traffic simulation models, providing an evaluation environment that can replicate actual deployment conditions at early stages of CAV development
