Abstract:Manufacturers are developing and promoting automated vehicles (AVs), which will have to perform in a variety of adverse weather conditions. With recent advancements in AV technology, the Federal Highway Administration is exploring AV needs, opportunities, and potential shortcomings during adverse weather conditions. The objective for Automated Vehicles and Adverse Weather Phase 3 (AVAW3) testing is to explore how adverse weather and road conditions in different driving environments affect AV dynamics and operations, driver behavior, communications, and AV sensor capabilities. This report presents scenarios, weather conditions, and driving environments applied for AVAW3 field tests, along with summaries of the test results, stakeholder engagement, and recommendations for potential future research. The first round of field tests occurred in spring/summer road weather conditions and assessed performance of AVs in Work Zone Lane Change with Barrels, Work Zone Lane Closure with Lane Markings, Pavement Markings with Brake Marks, and Pavement Markings with Disappearing Shoulder scenarios. The second round of field tests occurred under winter road conditions and assessed performance of AVs during Lane Keeping, Right Lane Changing, movements at a Green Signalized Intersection, and Stopped Car Detection scenarios.
