Connected and Automated Vehicle (CAV) technology has been recognized as having the potential to bring safety, mobility, and environmental benefits to our Nation’s surface transportation system. A recent study estimated the potential impacts of Automated Vehicles (AV) such as crash avoidance, reduced energy consumption and vehicle emissions, reduced travel times, and increased petroleum consumption through longer travels. Another research study conducted by Volpe center presented a framework for estimating the potential benefits and dis-benefits of technologies contributing to AVs. While the proposed framework has included methods to evaluate safety and environmental components, no specific tool or model was presented to assess the mobility benefits of AV technology. The other shortcoming of the study is that it has focused more on AVs and has not considered CAVs. The CAV technology has more interaction with infrastructure-related components that would result in substantial mobility improvement. Therefore, methodologies for cost benefit analysis are needed to not only evaluate mobility advantages of AV technology, but also of CAV. The intent of this research is to study the costs and benefits of deploying CAV technology along signalized corridors. Specifically, the research should explore innovations in benefit analysis of deploying systems such as Multi-Modal Intelligent Traffic Signal System (MMITSS) and Glidepath along arterials. The framework developed from this research will be designed to be incorporated into a larger, overall analysis framework for use by state and local transportation agencies to justify investment into CAV technology.
