Morning rush hour traffic on U.S. Highway 101 in San Francisco, Calif. on March 13, 2019. Berkeley researchers are addressing the emerging era of self-driving vehicles on multiple fronts, including a tool that uses machine learning to manage traffic where autonomous, partially-automated and manual vehicles share the road. Alexandre Bayen's project, called Flow, is the first time deep reinforcement learning has been integrated with traffic-simulation tools. (Photo by Adam Lau/Berkeley Engineering)
