Traffic as a research area focuses on the quantitative modeling, analysis, and control of flows of vehicles, pedestrians, or data units over networks, typically using tools from transportation engineering, operations research, applied mathematics, and complex systems science. It encompasses microscopic and macroscopic traffic flow theory, congestion formation and dissipation, network optimization, routing and assignment, signal control, and stability analysis of interacting agents. Research often integrates stochastic processes, queuing theory, game theory, and simulation to study capacity, reliability, safety, and efficiency, and increasingly leverages sensing, data analytics, and intelligent transportation systems to design adaptive, resilient, and sustainable mobility networks.
Since New York City introduced congestion pricing in January 2025, the state has heralded significant reductions in traffic and rush hour delays, fewer crashes and noise complaints, and toll revenue projected to hit $500 ...
