TrafSim is a scientific/research project that uses Agent-Based Modeling to simulate traffic. The aim is analyzing some emergent properties of interaction of these agents (cars/drivers) in a cross or high-way with U-turn structures.
Road traffic simulator/game with lots of vehicules, different drivers characteristics, accidents, detours, manual or script-driven traffic lights control, pedestrian traffic, road-works, and plenty more! Solve your simulated traffic-jams problems!
