SUMO (Simulation of Urban MObility) simulates individual vehicles, transit, cyclists, and pedestrians across entire city networks, imports OpenStreetMap directly, and exposes every simulation step through the TraCI API — which made it the de facto environment for connected-vehicle and reinforcement-learning traffic research.
Best for: researchers and cities running large-scale, scriptable traffic studies, V2X work, and signal-control ML experiments.
Consider alternatives when agencies require validated commercial workflows and polished deliverables (PTV Vissim).
