    • Abstract:
      When people hear the phrase "artificial intelligence" (AI), they might think of robots and machines that perform some of the functions that humans do, as such searching for victims in a partially collapsed building or comforting the elderly with personalized advice as part of monitoring their moods and home activity. When defined within the context of the transportation sector, AI conjures up futuristic images of self-driving, fully automated cars. Though these fantasies aren’t yet real, AI does have a lot of potential to positively impact our Nation’s transportation system in the near future. The use of AI to enable computers to digest and analyze large amounts of data and form conclusions—a process known as machine learning—can create many improvements to transportation beneficial to the American public. Highlights include: Improving traffic flows at signalized intersections along specific routes or as part of integrated corridor management, Aiding traffic management centers with improving crash detection, predicting traffic slowdowns, and recommending detours, Facilitating traffic safety by warning vehicles of pedestrians obscured by parked vehicles who are starting to cross the street and monitoring real-time traffic and weather conditions, Discerning and anticipating how drivers might react in certain traffic situations, Providing information to travelers with disabilities to assist in their trip planning and increase their situational awareness, Allowing traffic engineers and urban planners to better understand what variables may reduce the potential for traffic crashes or injuries, Reducing highway infrastructure repair and reconstruction costs by augmenting data from structural health monitoring of highway assets.
