Driving Smarter Mobility: From OpenStreetMap to Real-Time Traffic Simulation with SUMO & Godot
summary
A Lugano project converts OpenStreetMap into a real-time, city-scale traffic simulator by combining a React prototype, Godot rendering, and SUMO as the physics engine via a libsumo C# bridge. It models individual vehicles (acceleration, stops, traffic lights), supports editing lanes or closing streets, and reports a concrete metric — cost = vehicle waiting time — with real-time and cumulative heatmaps. Development spans weeks (web), ~1 month for Godot, ~1 month to integrate SUMO, and the demo runs successfully using OSM + SUMO + Godot.
