Summary
This document is a biannual highlights report from the Federal Highway Administration’s (FHWA) Turner-Fairbank Highway Research Center (TFHRC), specifically summarizing the activities of the Human Factors Team during the summer of 2021. The report addresses the resumption of data collection for various safety research projects following previous disruptions, focusing on human behavior in the context of emerging transportation technologies, infrastructure design, and mixed-vehicle fleets. The primary motivation is to advance safety research aligned with federal priorities regarding automated vehicles, pedestrian safety, and economic recovery. The report details several ongoing and completed research initiatives utilizing diverse methodologies. Data collection resumed in the Highway Driving Simulator (HDS) for studies on driver interactions with partial automation when passing bicyclists and responses to emergency vehicles in mixed fleets. Researchers also utilized the National Advanced Driving Simulator miniSim™ to investigate human factors related to truck platooning, recruiting FHWA staff as participants. Field research vehicles were modified to enable remote interactions for a study on vehicle automation and cooperative messaging in eco-driving. Additionally, the team adapted studies on variable message signs and overhead guide signs to use remote data collection methods, including web conferencing and facility-based recruitment. A significant technical development involved integrating the Cooperative Automation Research Program’s CARMA platform into the HDS to create a virtual replica of the TFHRC campus, aiming to combine road and simulation-based testing for cooperative-automated driving systems. Key findings and milestones include the completion of data collection for a project on enhancing the conspicuity of standard signs and retroreflectivity strips. The report highlights the publication of two technical reports: one on effective indicators for partially automated truck platooning and another on the effects of adaptive cruise control on driver engagement and mind wandering. The team also presented updates on aesthetically treated crosswalks and bicycle/pedestrian research at various conferences, including the National Association of County Engineers’ Annual Conference and the Transportation Association of Canada’s Spring Technical Meeting. Furthermore, the team initiated a new project in May 2021 to identify infrastructure solutions for ensuring the safety of vulnerable road users interacting with cooperative driving automation vehicles. The significance of this report lies in its documentation of the FHWA’s strategic shift toward integrating simulation technologies with real-world testing to evaluate human factors in automated and connected vehicle environments. The visual upgrade of the HDS with 4K high-resolution projectors underscores a commitment to improving simulation realism for future research. By aligning their work with the Biden Administration’s priority areas, the Human Factors Team demonstrates a coordinated effort to address safety, climate change, and economic recovery through rigorous empirical study and infrastructure innovation. The report serves as a status update on the operational capacity and research direction of the FHWA’s safety R&D program.
