Summary

This report, produced by the Minnesota Traffic Observatory for the Minnesota Department of Transportation, addresses the preparation requirements for local road owners facing the integration of Connected and Automated Vehicles (CAVs). The research was motivated by the anticipated impact of CAVs on transportation operations and roadway maintenance, aiming to clarify the distinction between Connected Vehicles (CVs), which communicate wirelessly, and Automated Vehicles (AVs), which rely on internal sensors. The study seeks to provide local agencies with actionable guidance to ensure infrastructure compatibility and minimize future deployment costs. The methodology involved a comprehensive literature review of CAV technologies, applications, and standards, alongside a survey of local road operators in Minnesota to assess current infrastructure readiness and stakeholder interest. The report categorizes CAV applications by automation levels, focusing primarily on Level 0 technologies that provide driver warnings without removing control. It details the hardware and communication requirements for these applications, including Dedicated Short-Range Communication (DSRC) Road-Side Units (RSUs), backhaul communication, and Security Credential Management Systems (SCMS). The analysis also evaluated the costs—both monetary and effort-based—associated with implementing various CV applications and retrofitting existing traffic signal controllers to meet modern standards like NTCIP and Advanced Transportation Controllers (ATC). Key findings indicate that while specific recommendations for CAV applications are premature due to evolving technology, general readiness measures are immediately actionable. The survey revealed varying levels of infrastructure readiness among local jurisdictions, with many relying on older controller technologies. The report identifies that most feasible near-term applications are Level 0, such as red light violation warnings and stop sign gap assists, which require minimal automation but significant communication infrastructure. Cost estimates for equipment and integration were provided for various applications, highlighting the financial and operational burdens of retrofitting legacy systems. The study also emphasized the importance of privacy and security standards in CV ecosystems. The significance of this work lies in its provision of a structured framework for local road owners to begin preparing for CAV integration. The authors recommend maintaining clear road markings and signage, modernizing roadway design information and traffic controllers, and developing communication infrastructure where feasible. They advise agencies to follow guidance from the U.S. Department of Transportation and local DOTs. Additionally, the report includes a deliverable matrix summarizing infrastructure needs and costs for high-interest applications, serving as a practical tool for local stakeholders to plan and prioritize their CAV readiness efforts.
