In this talk we discuss recent developments in microscopic traffic flow theory based on extensive analysis of vehicle trajectory data collected as part of the Next Generation Simulation (NGSIM) project, sponsored by the US Federal Highway Administration. First, we present a new behavioral algorithm for oversaturated freeway flow that can be readily used in microscopic simulation models. The proposed algorithm is an integrated car-following and lane changing modeling framework that is consistent with the kinematic wave theory. The algorithm can explicitly model mandatory and discretionary lane changing, including cooperation during lane changing. Also, the proposed algorithm accounts for the relaxation process following lane changing. Next, we propose an asymmetric traffic theory, and explain the frequently observed stop-and-go traffic phenomenon in light of the developed theory.
Alexander Skabardonis, Ph.D. is an internationally recognized expert in traffic flow theory and models, traffic management and control systems, design, operation and analysis of transportation facilities, intelligent transportation systems (ITS), and energy and environmental impacts of transportation. He is a Professor at the University of California, Berkeley, where he also serves as the Director of California PATH, a statewide ITS research center. He is a member of the Transportation Research Board (TRB), Freeway Operations, Traffic Flow Theory and Highway Capacity and Quality of Service Committees. He serves on the editorial board of the Intelligent Transportation Systems Journal, and as a reviewer for several archival journals in transportation.
