Summary
This document summarizes the findings of the Federal Highway Administration’s (FHWA) National Dialogue on Highway Automation Operations Workshop, held in October 2018. The workshop addressed the challenge of safely and efficiently integrating automated vehicles (AVs) into the national roadway network. Motivated by the potential of AVs to improve safety and mobility, as well as the uncertainty they introduce for infrastructure owners and operators (IOOs), the event aimed to gather stakeholder input to inform FHWA research, policies, and programs. Over 170 participants from government, industry, academia, and associations engaged in breakout sessions and interactive discussions to identify operational impacts, strategies, and action plans. The workshop utilized a structured design comprising three breakout sessions and a “Collaboration Corner.” Breakout Session I focused on AV impacts and operational issues, while Session II addressed strategies for managing system efficiency. The Collaboration Corner featured seven stations where participants provided input via sticky notes and suggestion boxes on topics including operational environments, workforce preparation, data needs, terminology, and research priorities. Session III focused on developing an action plan for the transportation community. This format allowed for both small-group deliberation and broad, informal feedback collection across diverse stakeholder groups. Key findings highlighted significant operational challenges, particularly regarding mixed fleets where automated and human-driven vehicles coexist. Participants identified complex environments such as work zones, adverse weather, poorly defined roadways, and interactions with emergency vehicles as critical areas requiring further study. There was a strong consensus on the need for clear guidance for IOOs, including workforce training resources and prioritization frameworks for infrastructure investments. Stakeholders emphasized the necessity of direct, two-way communication between IOOs and AV developers to share data on infrastructure conditions and vehicle performance. Additionally, participants noted that misinformation and inconsistent terminology hinder effective collaboration, calling for a harmonized lexicon and objective public outreach. Law enforcement and emergency responders specifically requested standard operating procedures for interacting with AVs, including protocols for pulling over vehicles and managing incidents. The significance of this workshop lies in its role in shaping federal and local approaches to AV integration. The collected input informs the development of technical guidance, research priorities, and readiness standards. Recommendations include establishing roadway readiness ratings, creating a national forum for dialogue on operational design domains, and standardizing emergency response procedures. The document underscores the importance of multijurisdictional coordination and data standardization to support nationwide AV interoperability. By identifying specific research needs, such as understanding AV behavior in mixed fleets and the impact of pavement markings on sensor performance, the workshop provides a roadmap for future FHWA initiatives aimed at ensuring the safe deployment of automated vehicles.
Key finding
Stakeholders identified mixed-fleet operations, challenging environmental scenarios, and the lack of standardized procedures for public safety interactions as primary operational barriers to AV integration.
