Adverse weather events can significantly affect vehicle and driver behavior. With the advent of automated vehicles (AVs), the Federal Highway Administration Road Weather Management Program has begun research and testing to identify how vehicles and drivers will detect and react to adverse weather and road weather conditions. AVs have sensors and perception systems to detect objects and events in their vicinity. Using this information, they control the steering or speed, or both, to move the vehicle along its selected path. Their ability to properly perceive the situation and execute a maneuver can be affected by atmospheric conditions and road weather. Several tests were developed and conducted with the intent to challenge perception systems across a variety of simulated adverse winter weather conditions in a controlled outdoor laboratory setting in traffic settings. The presentation will describe the tests and results that were obtained during the testing in Winter 2021 along with some videos.
